8TQ100STRL Schottky Diode Equivalent & Substitute Parts

Part Overview

The 8TQ100STRL is a Schottky rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, rated for 100 V DC reverse voltage and 8 A average rectified current in a surface mount TO-263AB (D2PAK) package. This part is classified as obsolete, necessitating identification of active equivalent and substitute components for new designs and production continuity. Equivalent parts maintain identical electrical and mechanical specifications, while substitute parts provide functional alternatives with modified parameters suitable for the same application circuit topology.

Engineering Selection Recommendations

Primary Equivalent Selection:

VS-8TQ100STRL-M3 is the direct equivalent replacement for the obsolete 8TQ100STRL. This part maintains identical electrical specifications (100 V, 8 A, 720 mV forward voltage) and mechanical compatibility (TO-263AB package). The part is active, RoHS3 compliant, and available in Tape & Reel packaging suitable for automated assembly. This selection eliminates obsolescence risk while maintaining design compatibility.

Alternative Equivalent (Tube Packaging):

VS-8TQ100S-M3 provides identical electrical and mechanical specifications to the main part with active product status and RoHS3 compliance. This variant is supplied in Tube packaging, suitable for lower-volume applications or manual assembly processes.

Automotive-Grade Equivalent:

VS-8TQ100SHM3 is an automotive-qualified variant (AEC-Q101) of the 8TQ100 series, maintaining identical electrical specifications and TO-263AB package compatibility. This part is suitable for automotive applications requiring formal qualification documentation.

Cross-Manufacturer Equivalent:

STPS8H100G-TR (STMicroelectronics) provides electrical equivalence with a marginally lower forward voltage (710 mV @ 8 A versus 720 mV @ 8 A) and superior reverse leakage characteristics (4.5 µA @ 100 V versus 550 µA @ 100 V). The part is active, RoHS3 compliant, and supplied in Cut Tape & Digi-Reel packaging. Mechanical compatibility is confirmed through D2PAK package equivalence to TO-263AB.

Higher Current Substitute:

DSS16-01AS-TRL (IXYS) provides a higher current rating (16 A versus 8 A) at the same 100 V reverse voltage. Forward voltage is 790 mV @ 15 A. This part is suitable for applications requiring increased current capacity within the same voltage class and package footprint. The part is active and RoHS3 compliant.

Frequently Asked Questions (FAQ)

Q: Can VS-8TQ100STRL-M3 be used as a direct replacement for 8TQ100STRL?

A: Yes. VS-8TQ100STRL-M3 is a parametric equivalent with identical electrical specifications (100 V, 8 A, 720 mV forward voltage) and mechanical compatibility (TO-263AB package). The primary difference is product status (Active versus Obsolete) and RoHS3 compliance. No circuit modifications are required.

Q: What is the difference between VS-8TQ100S-M3 and VS-8TQ100STRL-M3?

A: Both parts are parametric equivalents with identical electrical specifications. The difference is packaging: VS-8TQ100S-M3 is supplied in Tube packaging, while VS-8TQ100STRL-M3 is supplied in Tape & Reel (TR) packaging. Tape & Reel is standard for automated assembly; Tube packaging is used for manual assembly or lower-volume applications.

Q: Is VS-8TQ100SHM3 suitable for non-automotive applications?

A: Yes. VS-8TQ100SHM3 maintains identical electrical and mechanical specifications to the standard 8TQ100 series. The automotive qualification (AEC-Q101) is an additional certification that does not restrict use in non-automotive applications. This part is interchangeable with other 8TQ100 variants.

Q: Can STPS8H100G-TR replace 8TQ100STRL in all applications?

A: STPS8H100G-TR is electrically equivalent with a lower forward voltage (710 mV @ 8 A versus 720 mV @ 8 A) and superior reverse leakage performance (4.5 µA @ 100 V versus 550 µA @ 100 V). The D2PAK package is mechanically compatible with TO-263AB. This part is suitable for direct replacement in applications where the improved leakage characteristics are beneficial or neutral.

Q: When should DSS16-01AS-TRL be selected instead of the 8 A equivalent?

A: DSS16-01AS-TRL should be selected when the application circuit requires current capacity exceeding 8 A but within the 100 V voltage class. The 16 A rating provides design margin for higher-power applications. The forward voltage (790 mV @ 15 A) is higher than the 8 A equivalent; verify that power dissipation and thermal management remain acceptable.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All active substitute parts listed (VS-8TQ100S-M3, VS-8TQ100SHM3, VS-8TQ100STRL-M3, STPS8H100G-TR, DSS16-01AS-TRL) are RoHS3 compliant. The original 8TQ100STRL is RoHS non-compliant, making migration to an active equivalent necessary for new designs subject to RoHS requirements.

Q: What is the Moisture Sensitivity Level (MSL) for all substitute parts?

A: All substitute parts maintain MSL 1 (Unlimited), identical to the original 8TQ100STRL. This classification indicates no moisture sensitivity restrictions during storage or handling.

Q: Can the package footprint be used interchangeably between TO-263AB and D2PAK?

A: Yes. TO-263AB and D2PAK are equivalent package designations for the same physical form factor (2 Leads + Tab, surface mount). Parts specified with either designation are mechanically and electrically compatible on the same PCB footprint.
