6TQ045S

Overview

The Vishay 6TQ045S is a single Schottky rectifier in a D2PAK package, rated for 6 A average forward current and 45 V maximum DC reverse voltage. It features a low forward voltage drop of 0.53 V at 6 A and 125 °C junction temperature, with a maximum reverse leakage current of 7 mA at 125 °C. The device supports operation up to 175 °C junction temperature and withstands a non-repetitive surge current of 690 A.

Feature Summary

Optimized for high-frequency switching applications with low forward voltage drop
High purity epoxy encapsulation provides enhanced mechanical strength and moisture resistance
Guard ring design ensures ruggedness and long-term reliability
Qualified for automotive Q101 level standards

Applications

Switching power supplies
DC-DC converters
Freewheeling diodes
Reverse battery protection circuits

Procurement Notes

Verify the specific ordering suffix (e.g., TRL, TRR) to confirm tape and reel orientation and packaging quantity. Confirm lead-free status via the M3 suffix if required. Ensure thermal management aligns with the specified junction-to-case thermal resistance for the intended duty cycle.

Selection Notes

Select this component for high-efficiency rectification where low forward voltage drop minimizes power loss. Verify that the 45 V rating exceeds the peak reverse voltage in the circuit. Consider the D2PAK package for surface mount assembly and adequate heat dissipation capabilities up to 175 °C.

Part Context

Part of the 6TQ...S Schottky rectifier series designed for high-power applications. The series utilizes proprietary barrier technology to maintain low reverse leakage at elevated temperatures. Available in multiple voltage ratings including 35 V and 40 V variants within the same package footprint.

Replacement Considerations

Direct substitutes include other Vishay 6A Schottky rectifiers in D2PAK packages such as the 6TQ040S or 6TQ035S, provided the reverse voltage requirements are met. Cross-brand replacements must match the 6 A current rating, 45 V minimum blocking voltage, and D2PAK outline dimensions.
