FMU-12S

Diode Arrays Overview

The FMU-12S is a silicon diode with a resin molded structure designed for high-frequency rectification. It features a transient peak reverse voltage of 250 V and a peak reverse voltage of 200 V. The average forward current rating is 5.0 A, while the peak surge forward current reaches 30 A for a 10 ms half-sine wave pulse. Electrical characteristics include a maximum forward voltage drop of 1.5 V at 2.5 A and a maximum reverse leakage current of 50 uA at VRM. Reverse recovery time is specified as 400 ns max at 90% recovery point and 180 ns max at 75% recovery point. Thermal resistance from junction to case is 4.0 °C/W max.

Diode Arrays Procurement Notes

Verify component authenticity against official Sanken Electric documentation. Confirm package dimensions and marking codes match the provided datasheet specifications. Ensure compliance with UL94V-0 flammability requirements if applicable to the end-use environment. Check for availability status as the component may be restricted for new designs.

Diode Arrays Selection Notes

Evaluate thermal management requirements based on the 4.0 °C/W junction-to-case resistance. Consider derating curves for average forward current relative to case temperature. Verify that the 200 V peak reverse voltage meets circuit operating conditions. Assess reverse recovery time suitability for specific switching frequencies in the target application.
