Single Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation before procurement. Suffixes such as 'TRL' or 'TRR' indicate tape and reel packaging orientation, while 'H' denotes AEC-Q101 qualification. Confirm that the selected variant matches the required packaging format and automotive qualification status for your specific application requirements.

Single Diodes Selection Notes

Select this component when designing circuits requiring a single Schottky rectifier with a 20 A continuous current rating and a 45 V reverse voltage capability. Ensure the thermal management strategy accommodates the specified maximum junction temperature of 150 °C and the thermal resistance characteristics provided in the datasheet for the intended operating environment.

Single Diodes Part Context

This part belongs to the VS-20TQ... Schottky rectifier series, which includes variants with different voltage ratings such as 35 V and 40 V. All members of this series share the same 20 A current rating, D2PAK package, and core technological features optimized for low forward voltage drop and high-frequency operation in power electronics applications.

Single Diodes Replacement Considerations

Direct substitutes within the same series include VS-20TQ035SHM3 and VS-20TQ040SHM3, which offer identical current and package specifications but lower reverse voltage ratings of 35 V and 40 V respectively. Verify that the system voltage does not exceed the replacement part's maximum working peak reverse voltage.
