10TQ035

Overview

The Vishay 10TQ035 is a single Schottky rectifier in the PbF series, housed in a TO-220AC package with an exposed cathode base. It features a maximum average forward current of 10 A and a maximum DC reverse voltage of 35 V. The device supports junction temperatures up to 175 °C and offers a typical forward voltage drop of 0.49 V at 10 A and 125 °C. Key electrical parameters include a non-repetitive surge current capability of 1050 A (5 µs sine) and a maximum reverse leakage current of 2 mA at 25 °C.

Feature Summary

• Optimized for low reverse leakage current at elevated temperatures using proprietary barrier technology
• High frequency operation capability combined with low forward voltage drop
• Guard ring structure designed to enhance ruggedness and long-term reliability
• High purity, high temperature epoxy encapsulation providing enhanced mechanical strength and moisture resistance

Applications

• Switching power supplies
• Converters

Procurement Notes

Verify the specific ordering suffix when purchasing. The standard production version lacks the PbF suffix, while lead-free variants require the PbF designation. Confirm compliance requirements against the datasheet specifications before procurement. Ensure the package style matches the required mounting configuration for the target application design.

Selection Notes

Select this component for applications requiring reliable operation at junction temperatures up to 175 °C. The TO-220AC package facilitates heatsinking via the exposed cathode base. Evaluate thermal resistance characteristics against the expected duty cycle and ambient conditions to ensure the average forward current rating remains within safe operating limits.

Part Context

This part belongs to the Vishay 10TQ...PbF Schottky rectifier series, which includes variants with different voltage ratings such as the 10TQ045. The series is engineered for industrial level qualification and utilizes silicon technology. The TO-220AC package provides a standardized footprint for through-hole mounting in high-power discrete semiconductor applications.

Replacement Considerations

Direct substitutes are not explicitly listed in the provided documentation. Verify pinout compatibility and thermal resistance values when considering alternative manufacturers. Ensure replacement devices meet or exceed the 175 °C junction temperature rating and 35 V reverse voltage specification.

FAQ

What is the maximum junction temperature for the 10TQ035?

The maximum junction temperature range is -55 °C to 175 °C.
