Vishay Intertechnology, Inc. introduced a versatile new 30 V n-channel TrenchFET® Gen V power MOSFET that delivers increased power density and enhanced thermal performance for industrial, computer, consumer, and telecom applications.
Featuring source flip technology in the 3.3 mm by 3.3 mm PowerPAK® 1212-F package, the Vishay Siliconix SiSD5300DN provides best in class on-resistance of 0.71 mΩ at 10 V and on-resistance times gate charge — a critical figure of merit (FOM) for MOSFETs used in switching applications — of 42 mΩ*nC.
Occupying the same footprint as the PowerPAK 1212-8S, the device released today offers 18 % lower on-resistance to increase power density, while its source flip technology reduces thermal resistance by 63 °C/W to 56 °C/W. In addition, the SiSD5300DN’s FOM represents a 35 % improvement over previous-generation devices, which translates into reduced conduction and switching losses to save energy in power conversion applications.
PowerPAK1212-F source flip technology reverses the usual proportions of the ground and source pads, extending the area of the ground pad to provide a more efficient thermal dissipation path and thus promoting cooler operation. At the same time, the PowerPAK 1212-F minimizes the extent of the switching area, which helps to reduce the impact of trace noise.
In the PowerPAK 1212-F package specifically, the source pad dimension increases by a factor of 10, from 0.36 mm2 to 4.13 mm2, enabling a commensurate improvement in thermal performance. The PowerPAK1212-F’s center gate design also simplifies parallelization of multiple devices on a single-layer PCB.
The source flip PowerPAK1212-F package of the SiSD5300DN is especially suitable for applications such as secondary rectification, active clamp battery management systems (BMS), buck and BLDC converters, OR-ing FETs, motor drives, and load switches. Typical end products include welding equipment and power tools; servers, edge devices, supercomputers, and tablets; lawnmowers and cleaning robots; and radio base stations.

Siltronic AG has published its forecast for the financial year 2024 in an ad-hoc announcement. Due to the weakness in demand, as a result of elevated customer inventories and the associated further postponement of delivery volumes, the Executive Board expects sales for the current financial year to be in the region of the previous year.
The first six months of the financial year 2024 are likely to be affected most by the postponement of delivery volumes, meaning that sales for this reporting period are expected to be at the level of H2 2023. The forecast is based on a Euro/US Dollar exchange rate of 1.10. On a positive note, average selling prices are expected to remain stable.
The EBITDA margin, before ramp costs, will also be in the region of the previous year. Due to the commissioning of our new state-of-the-art 300 mm fab in Singapore, the margin will be reduced by up to three percentage points compared to the previous year. Ramp costs primarily comprise energy, material and labor costs.
“Our strategic growth targets until 2028 remain unchanged. In the short-term, however, the continuing weakness in demand will weigh on the development in the financial year 2024. In addition, the expected ramp costs for our new 300 mm fab in Singapore will become noticeable. With the increase in production volume over the next few years, the fab will contribute significantly to the profitable growth of Siltronic. Therefore, we stick to our medium-term ambition and expect sales to grow to more than EUR 2.2 billion and an EBITDA margin in the high 30’s until 2028,” commented Dr. Michael Heckmeier, CEO of Siltronic AG.
The Executive Board expects a noticeable reduction in energy and material costs (before ramp costs) in 2024 compared to the previous year. However, the positive effect will roughly be compensated by rising labor tariffs and the lower currency hedging result compared to the previous year. The high level of capital expenditure in recent years will almost double depreciation and amortization compared to the previous year. As a result, the EBIT will be significantly lower than in the previous year.
As already announced, capital expenditure will be more than halved compared to the previous year’s record level of EUR 1,316 million. Therefore, the company expects a significant improvement in net cash flow, although it will still remain significantly negative.
Growth targets until 2028 remain unchanged
As communicated in November 2023, significant sales growth to more than EUR 2.2 billion and an improvement of the EBITDA margin to the high 30’s are expected until 2028. This confidence is driven by the increasing relevance of global megatrends such as artificial intelligence, digitalization and electromobility and will lead to a sharp rise in demand for semiconductors and therefore also for wafers. The increase in Group profitability will be primarily driven by expected volume growth and higher cost efficiency, which will be significantly above the expected inflation-related cost increases.
Future use of funds with focus on growth, innovation and debt reduction –
Dividend proposal of EUR 1.20 for 2023 due to persistent weakness in demandSiltronic will use the cash flows generated as a result of the above mentioned targets primarily for further organic growth, strengthening its innovative power and reducing debt. The latter had increased noticeably due to the high level of capital expenditure in the recent past. Nevertheless, Siltronic shareholders will continue to participate in the company’s success through a dividend. In view of the current difficult market situation, the Executive Board will propose to the Annual General Meeting on May 13, 2024 the payment of a dividend of EUR 1.20 per share for the financial year 2023 and thus a payout ratio of around 20 percent of the Group profit attributable to Siltronic shareholders.
“As a company in a capital-intensive and cyclical industry, we know how important a solid balance sheet policy and a forward-looking liquidity management are. That is why we will put an even stronger focus on our costs and capex this year. In view of the upcoming refinancing needs, we are convinced that our dividend proposal of EUR 1.20 represents an appropriate balance between capital discipline on the one hand and dividend continuity for our shareholders on the other,” explains Claudia Schmitt, CFO of Siltronic AG.
Despite this noticeable reduction compared to the previous year, Siltronic confirms its dividend policy for the future, according to which around 40 percent of the Group profit determined in accordance with IFRS principles, attributable to the shareholders of Siltronic AG, will be distributed. The upper limit remains unchanged at EUR 3.00 per dividend-bearing share.

Power Integrations announced financial results for the quarter and year ended December 31, 2023. Net revenues for the fourth quarter were $89.5 million, down 29 percent compared to the prior quarter and down 28 percent from the fourth quarter of 2022. GAAP net income for the fourth quarter was $14.3 million or $0.25 per diluted share compared to $0.34 per diluted share in the prior quarter and $0.40 per diluted share in the fourth quarter of 2022.
For the full year, net revenues were $444.5 million, compared to $651.1 million in the prior year. Full-year GAAP net income was $55.7 million or $0.97 per diluted share compared to $2.93 per diluted share in the prior year. Full-year cash flow from operations was $65.8 million.
In addition to its GAAP results, the company provided non-GAAP measures that for the fourth quarter of 2023 exclude stock-based compensation, amortization of acquisition-related intangible assets and the related tax effects. Non-GAAP net income for the fourth quarter of 2023 was $12.7 million or $0.22 per diluted share compared to $0.46 per diluted share in the prior quarter and $0.48 per diluted share in the fourth quarter of 2022. For the full year, non-GAAP net income was $74.5 million or $1.29 per diluted share compared to $3.29 per diluted share in the prior year. A reconciliation of GAAP to non-GAAP financial results is included with the tables accompanying this press release.
Commented Balu Balakrishnan, chairman and CEO of Power Integrations: “Fourth-quarter revenues declined as expected, and we project first-quarter sales to be about flat sequentially due to continued soft demand and elevated supply-chain inventories. However, channel inventory fell significantly in the fourth quarter, and we expect a further reduction in the first quarter. Based on lower inventories and seasonal patterns we expect sequential revenue growth beginning in the June quarter. We also expect gross margin to rise in the June quarter driven by the dollar/yen exchange rate, higher manufacturing utilization and end-market mix.”
During the fourth quarter Power Integrations repurchased 680 thousand shares of its common stock for $47.4 million. The company had $26.0 million remaining on its repurchase authorization as of December 31, 2023. Power Integrations paid a dividend of $0.20 per share on December 29, 2023, and will pay a dividend of $0.20 per share on March 29, 2024, to stockholders of record as of February 29, 2024.
Financial Outlook
The company issued the following forecast for the first quarter of 2024:
- Revenues are expected to be $90 million plus or minus $5 million.
- GAAP gross margin is expected to be approximately 51.5 percent; non-GAAP gross margin is expected to be approximately 52.5 percent. The difference between GAAP and non-GAAP gross margins is equally attributable to stock-based compensation and amortization of acquisition-related intangible assets.
- GAAP operating expenses are expected to be approximately $49 million; non-GAAP operating expenses are expected to be approximately $42.5 million. Non-GAAP operating expenses are expected to exclude about $6.5 million of stock-based compensation.
