STTH810G Equivalent & Substitute Parts

Part Overview

The STTH810G is a general-purpose fast recovery rectifier diode rated for 1000 V DC reverse voltage and 8 A average rectified current in a surface mount D2PAK package. This component is classified as obsolete, which necessitates identification of equivalent substitute parts for ongoing design support and procurement continuity. The STTH810G-TR provides a direct functional equivalent with identical electrical specifications and improved product status classification.

Substitute Part Grouping Explanation

Substitution of the STTH810G is determined by equivalence across the following critical parameters:

Voltage Rating: DC reverse voltage of 1000 V (maximum)
Current Rating: Average rectified current of 8 A
Forward Voltage Drop: 2 V maximum at 8 A forward current
Recovery Characteristics: Fast recovery classification with 85 ns reverse recovery time
Package Compatibility: TO-263-3 D2PAK surface mount configuration
Thermal Rating: 175°C maximum junction temperature
Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The STTH810G-TR meets all these criteria and is therefore classified as a direct equivalent substitute. Both parts share identical electrical performance specifications and mechanical packaging, with the primary distinction being product status and packaging format.

Product Status: The STTH810G-TR maintains active product status, ensuring long-term availability and supply chain continuity compared to the obsolete STTH810G.
Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements.
Moisture Sensitivity: The STTH810G-TR features MSL 1 (unlimited shelf life) compared to MSL 3 (168 hours) for the STTH810G, providing improved handling and storage flexibility.

Frequently Asked Questions (FAQ)

Q: Can the STTH810G-TR be used as a direct replacement for the STTH810G in existing designs?

A: Yes. The STTH810G-TR is electrically and mechanically equivalent to the STTH810G. All voltage ratings, current ratings, forward voltage characteristics, and recovery times are identical. The D2PAK package footprint is identical, permitting direct PCB substitution without design modification.

Q: What is the difference between STTH810G and STTH810G-TR?

A: The primary differences are product status and packaging format. The STTH810G is classified as obsolete, while the STTH810G-TR is active. The STTH810G-TR is supplied in Cut Tape (CT) and Digi-Reel® packaging formats. The STTH810G-TR also features improved moisture sensitivity level (MSL 1 versus MSL 3), providing unlimited shelf life compared to 168-hour storage limits.

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

A: No. Both parts share identical maximum junction temperature ratings (175°C), reverse recovery time (85 ns), forward voltage drop (2 V @ 8 A), and reverse leakage current (5 µA @ 1000 V). Thermal and electrical performance are equivalent.

Q: What packaging options are available for the STTH810G-TR?

A: The STTH810G-TR is supplied in Cut Tape (CT) and Digi-Reel® packaging formats. Both formats contain the same D2PAK surface mount component.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the STTH810G and STTH810G-TR are ROHS3 compliant and REACH unaffected. Both parts carry the same ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

Q: Why is the STTH810G classified as obsolete?

A: The STTH810G has reached end-of-life status. The STTH810G-TR serves as the active replacement part, ensuring continued availability and supply chain support for this rectifier diode specification.
