VS-8TQ080STRLHM3 Equivalent & Substitute Parts

Part Overview

The VS-8TQ080STRLHM3 is an 80V, 8A Schottky diode manufactured by Vishay General Semiconductor - Diodes Division, designed for surface mount applications in the TO-263AB (D2PAK) package. This component is classified as a fast recovery Schottky rectifier with automotive-grade qualification (AEC-Q101) and is currently in active production status. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when packaging format requirements differ.

Substitute Part Grouping Explanation

Substitute parts for the VS-8TQ080STRLHM3 are identified based on electrical and mechanical parameter equivalence. The primary substitution criterion is the matching of all critical electrical specifications: reverse voltage rating (80V), average rectified current (8A), forward voltage drop (720 mV @ 8A), recovery speed (Fast Recovery ≤ 500ns), reverse leakage current (550 µA @ 80V), and junction capacitance (500pF @ 5V, 1MHz). The package type must remain TO-263AB (D2PAK) to ensure mechanical and thermal compatibility with existing PCB layouts and thermal management designs. Operating temperature range (-55°C to 175°C), technology classification (Schottky), and automotive qualification (AEC-Q101) must be maintained. The only permitted variation is packaging format (Tape & Reel versus Tube), which affects supply chain logistics but does not alter electrical or mechanical performance.

Engineering Selection Recommendations

Both the VS-8TQ080STRLHM3 and VS-8TQ080S-M3 are active production parts from Vishay General Semiconductor - Diodes Division with identical electrical and mechanical specifications. Selection between these parts is determined by supply chain and inventory requirements rather than technical performance criteria. The VS-8TQ080STRLHM3 is supplied in Tape & Reel format, suitable for high-volume automated assembly operations. The VS-8TQ080S-M3 is supplied in Tube format, suitable for lower-volume applications or manual assembly processes. Both parts maintain ROHS3 compliance, unlimited moisture sensitivity rating (MSL 1), and automotive-grade qualification. The choice between these substitutes does not affect circuit performance, thermal management, or reliability characteristics.

Frequently Asked Questions (FAQ)

Q: Can VS-8TQ080S-M3 be used as a direct replacement for VS-8TQ080STRLHM3?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: Tape & Reel versus Tube. This affects handling and assembly processes but not component performance.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts share identical specifications for reverse voltage (80V), forward current (8A), forward voltage drop (720 mV @ 8A), recovery speed (Fast Recovery ≤ 500ns), reverse leakage current (550 µA @ 80V), and junction capacitance (500pF @ 5V, 1MHz).

Q: Do both parts meet automotive qualification requirements?

A: The VS-8TQ080STRLHM3 is explicitly qualified to AEC-Q101. The VS-8TQ080S-M3 qualification status is not specified in the provided data.

Q: What is the difference between Tape & Reel and Tube packaging?

A: Tape & Reel packaging is used for automated pick-and-place assembly in high-volume manufacturing. Tube packaging is used for manual assembly or lower-volume applications. Both formats contain the same component and provide identical electrical performance.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. Both parts use the TO-263AB (D2PAK) package with identical pin configuration, footprint, and thermal characteristics. PCB layouts and thermal designs require no modification.
