WNS40H100CQ

Diode Arrays Overview

The WNS40H100CQ is a dual power Schottky diode manufactured by WeEn Semiconductors, designed for high-efficiency rectification in power supply applications. It features a common cathode configuration with two independent anodes within a single package. The device supports a repetitive reverse voltage (VRRM) of 100 V and an average forward current (IF) of 20 A per section. The maximum forward voltage (VF) is specified at 770 mV, while the non-repetitive peak forward surge current (IFSM) reaches 250 A. Operating temperatures range up to +175 °C, ensuring reliability under thermal stress.

Diode Arrays Feature Summary

Diode Arrays Procurement Notes

Verify the specific ordering suffix and marking code against the official datasheet to ensure compatibility with your assembly process. Confirm that the TO-220AB-3 package dimensions match your PCB footprint requirements. Check for any recent lifecycle status updates or alternative recommendations from the manufacturer before finalizing procurement plans.

Diode Arrays Selection Notes

Select this component when a dual-channel rectifier with low forward voltage is required in a through-hole package. Ensure the 100 V reverse voltage rating exceeds the peak inverse voltage in the circuit. Verify that the 20 A current rating accommodates the RMS load current, considering derating factors for ambient temperature and thermal resistance.

Diode Arrays Part Context

This part belongs to the WNS series of silicon carbide Schottky diodes from WeEn Semiconductors. These devices are engineered for high-frequency applications where traditional silicon diodes suffer from high reverse recovery charges. The TO-220AB-3 package provides robust mechanical mounting and efficient heat dissipation capabilities suitable for industrial power electronics.

Diode Arrays Replacement Considerations

Consult official substitution lists for equivalent dual Schottky diodes in TO-220 packages. Verify pinout compatibility and electrical parameter margins before replacing. Generic equivalents may differ in thermal characteristics or packaging tolerances.
