18TQ035STRL

Overview

The Vishay 18TQ035STRL is a Schottky rectifier in the D2PAK (TO-263) surface-mount package. It features an average forward current rating of 18 A and a maximum repetitive peak reverse voltage of 35 V. The device supports junction temperatures up to 175 °C and offers a typical forward voltage drop of 0.53 V at 18 A and 125 °C. Electrical characteristics include a maximum reverse leakage current of 2.5 mA at 25 °C and a typical junction capacitance of 1400 pF.

Feature Summary

Optimized for low reverse leakage current at elevated temperatures
Proprietary barrier technology enables reliable operation up to 175 °C junction temperature
Guard ring structure provides enhanced ruggedness and long-term reliability
High purity, high temperature epoxy encapsulation ensures mechanical strength and moisture resistance

Applications

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

Procurement Notes

Verify the specific ordering suffix 'TRL' corresponds to left-oriented tape and reel packaging as defined in the manufacturer's ordering information table. Confirm that the component meets lead-free (PbF) requirements if applicable to the assembly process. Ensure the selected variant matches the required voltage rating within the 35 V to 45 V range.

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 when designing heatsinking solutions. Verify that the 1800 A non-repetitive surge current capability aligns with the circuit's transient requirements. Ensure the operating case temperature remains within the allowable limits defined by the duty cycle.

Part Context

This part belongs to the Vishay 18TQ...S Schottky rectifier series, which includes variants with different voltage ratings such as 40 V and 45 V. The series is designed for high-power applications utilizing proprietary barrier technology. The D2PAK package allows for efficient surface-mount assembly while maintaining robust thermal performance for high-current scenarios.

Replacement Considerations

Direct substitutes within the same series include the 18TQ040S and 18TQ045S for higher voltage requirements. Cross-manufacturer replacements must match the 18 A current rating, 35 V minimum reverse voltage, and D2PAK package dimensions. Verify thermal resistance and forward voltage characteristics to ensure equivalent performance.
