18TQ035

Overview

The Vishay 18TQ035 is a Schottky rectifier with an average forward current rating of 18 A and a maximum DC reverse voltage of 35 V. It operates within a junction temperature range of -55 °C to 175 °C. The device features a maximum forward voltage drop of 0.60 V at 25 °C and 0.53 V at 125 °C, both measured at 18 A. Maximum reverse leakage current is 2.5 mA at 25 °C and 25 mA at 125 °C. It utilizes a TO-220AC package.

Feature Summary

Optimized for low reverse leakage current at elevated temperatures
Proprietary barrier technology enables reliable operation up to 175 °C junction temperature
High purity 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 the specific ordering suffix when sourcing this component. Standard production versions are available without suffixes, while lead-free variants carry a PbF designation. Confirm that the required voltage rating matches the 35 V specification, as other ratings exist within the same series. Ensure compliance with RoHS requirements if applicable to the manufacturing process.

Selection Notes

Select this component for applications requiring high-frequency operation and low forward voltage drop. Consider the thermal resistance of 1.50 °C/W from junction to case when designing heatsinking solutions. Verify that the peak repetitive reverse voltage requirement does not exceed 35 V. Evaluate the surge current capability against potential inductive load conditions.

Part Context

This part belongs to the 18TQ... Schottky rectifier series manufactured by Vishay High Power Products. The series includes variants with different voltage ratings, specifically 40 V and 45 V options. All devices share the same 18 A current rating and utilize the TO-220AC package style.
