12TQ035

Overview

The Vishay 12TQ035 is a Schottky rectifier in the 12TQ series, rated for a maximum DC reverse voltage of 35 V and an average forward current of 15 A. It utilizes TO-220AC packaging with a base cathode configuration. The device supports junction temperatures up to 150 °C and features a typical forward voltage drop of 0.50 V at 15 Apk and 125 °C. Maximum non-repetitive surge current reaches 990 A under specific pulse conditions.

Feature Summary

• Optimized for very low forward voltage drop with moderate leakage characteristics
• Reliable operation supported by proprietary barrier technology up to 150 °C junction temperature
• High purity, high temperature epoxy encapsulation provides enhanced mechanical strength and moisture resistance
• Guard ring design ensures enhanced ruggedness and long term reliability

Applications

• Switching power supplies
• Converters
• Freewheeling diodes
• Reverse battery protection

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lead-free marking on the package. Ensure thermal management meets the specified junction-to-case thermal resistance requirements during installation.

Selection Notes

Select this component for applications requiring low forward voltage drop and high frequency operation. Verify that the operating junction temperature remains within the -55 to 150 °C range. Consider the 15 A average forward current rating and ensure adequate heatsinking to maintain case temperature limits.

Part Context

This part belongs to the Vishay 12TQ... Series of Schottky rectifiers. The series includes variants with different voltage ratings (35 V, 40 V, 45 V) but shares the same 15 A current rating and TO-220 package style. The 'Q' designation indicates the specific Schottky series generation.
