Diode Arrays Procurement Notes

Verify the specific datasheet revision, currently Rev.1.1 dated July 05, 2022, against your procurement requirements. Confirm that the application does not fall under Sanken's excluded high-reliability categories, such as aerospace or medical devices, without prior written authorization. Ensure compliance with export control regulations if applicable.

Diode Arrays Selection Notes

Select this component for applications requiring robust 30 A handling with fast switching speeds. The TO3PF-3L package facilitates direct heatsink mounting via screw terminals. Evaluate derating curves for average forward current based on the expected case temperature and duty cycle to ensure reliable operation within the -40 to 150 °C junction temperature range.

Diode Arrays Part Context

This component belongs to Sanken Electric's line of silicon fast recovery rectifiers designed for high-efficiency power conversion. The FMN-4306S utilizes a planar passivation structure to enhance reliability. It is distinct from standard rectifiers due to its minimized reverse recovery charge, making it suitable for high-frequency switching environments where low switching losses are critical.
