Single Diodes Procurement Notes

Verify the specific datasheet revision (EM1B-DSE Rev.1.4) before implementation, as Sanken Electric may update product information without notice. Confirm that the application environment complies with the specified absolute maximum ratings and derating curves provided in the official documentation to ensure long-term reliability.

Single Diodes Selection Notes

Select this component when designing commercial power supplies requiring high-voltage blocking capability up to 800 V. Ensure the circuit design accounts for the thermal resistance between the junction and lead, which is rated at 17 °C/W. Verify that the surge forward current requirements do not exceed the 35 A half-cycle sine wave limit.
