8TQ100STRR

Single Diodes Overview

The Vishay 8TQ100STRR is an 8 A Schottky rectifier with a 100 V maximum DC reverse voltage (VRRM). It operates within a junction temperature range of -55 °C to 175 °C and features a low forward voltage drop of 0.58 V at 8 A and 125 °C. The device supports a non-repetitive peak surge current of 850 A and has a maximum thermal resistance of 2.0 °C/W from junction to case. Packaged in a D2PAK surface-mount housing, it is supplied in tape-and-reel format.

Single Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package orientation and lead-free status. The 'TRR' designation indicates right-oriented tape and reel packaging. Confirm RoHS compliance and Pb-free markings on the component body. Ensure the supplier provides valid traceability documents matching the manufacturer's part number and revision history.

Single Diodes Selection Notes

Select this component when designing circuits requiring high-frequency operation and low forward voltage drop under high thermal loads. The 175 °C junction temperature rating allows for robust performance in compact switching power supply designs without excessive heatsinking. Verify that the 100 V reverse voltage rating exceeds the circuit's peak inverse voltage requirements.

Single Diodes Part Context

This component belongs to the Vishay 8TQ...S Schottky rectifier series, which includes variants with different voltage ratings such as 80 V and 100 V. All members of this series share the same 8 A average forward current rating and D2PAK package style. The series is engineered specifically for applications demanding high reliability and low reverse leakage characteristics.

Single Diodes Replacement Considerations

Official substitutes include other Vishay 8TQ series parts like the 8TQ080S for lower voltage applications. Cross-manufacturer replacements must match the 8 A current rating, 100 V reverse voltage, D2PAK footprint, and 175 °C thermal capability.
