FMU-22S

Diode Arrays Overview

The FMU-22S is a high-frequency rectification silicon diode manufactured by Sanken Electric. It features a peak reverse voltage of 200 V and an average forward current rating of 10 A, with a transient peak reverse voltage capability of 250 V. The device supports a peak surge forward current of 40 A for 10 ms half-sine waves. Electrical characteristics include a maximum forward voltage drop of 1.5 V at 5.0 A and a reverse recovery time of 400 ns under standard conditions. Thermal resistance from junction to case is limited to 4.0 °C/W. Operating temperatures range from -40 °C to +150 °C.

Diode Arrays Procurement Notes

Verify the specific datasheet revision (61426-01) matches your design requirements. Confirm that the component status is acceptable for your project lifecycle, as it is marked Not Recommended for New Designs. Ensure thermal management aligns with the provided derating curves for case temperature versus average forward current. Check polarity marking conventions on the package body during assembly.

Diode Arrays Selection Notes

Select this component when a robust silicon diode with 200 V reverse voltage and 10 A average current capacity is required for high-frequency operation. Consider the 400 ns reverse recovery time for switching speed requirements. Evaluate thermal performance against the 4.0 °C/W junction-to-case resistance. Verify compatibility with the specified operating temperature range of -40 °C to +150 °C.

Diode Arrays Part Context
