T40HFL10S02

Single Diodes Overview

The T40HFL10S02 is a fast recovery power diode module from the Vishay T-Module series, rated for a maximum average forward current of 40 A and a repetitive peak reverse voltage of 100 V. It features a single diode configuration within a D-55 package, providing electrical isolation between the semiconductor junction and the metal base plate. The device exhibits a maximum reverse recovery time of 70 ns at a di/dt of 100 A/μs and operates within a junction temperature range of -40 °C to +125 °C.

Single Diodes Procurement Notes

Verify the specific voltage code (10) and recovery time code (S02) against the datasheet ordering information table to ensure correct part selection. Confirm that the application requires the 100 V rating and 70 ns recovery characteristic specified for this suffix combination. Ensure thermal interface materials are compatible with the D-55 case style.

Single Diodes Selection Notes

Select this component when a single-diode fast recovery solution with an electrically isolated base is required. The 40 A current rating and 100 V blocking capability define the operational limits. Consider the 70 ns reverse recovery time for high-frequency applications where low switching losses are critical compared to standard recovery alternatives.

Single Diodes Part Context

This module belongs to the T40HFL series, which shares the same 40 A current rating but offers various voltage and recovery time combinations. The S02 suffix specifically denotes the 70 ns reverse recovery speed, while the '10' indicates the 100 V voltage rating. Other variants in the family include higher voltage ratings up to 1000 V and slower recovery options.

Single Diodes Replacement Considerations

Direct substitutes within the same series include T40HFL20S02 (200 V), T40HFL40S02 (400 V), and T40HFL60S02 (600 V). For different recovery speeds, T40HFL10S05 (500 ns) and T40HFL10S10 (1000 ns) are available. Cross-brand replacements require matching the D-55 footprint, 40 A rating, and isolation requirements.
