TPC13HM3/87A Equivalent & Substitute Parts

Part Overview

The TPC13HM3/87A is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This component is designed for transient overvoltage protection in automotive applications, featuring a 10.5V reverse standoff voltage and 19V maximum clamping voltage. The part is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity. The TPC13AHM3_A/I serves as a direct functional equivalent from the same manufacturer series.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for TVS diodes is determined by the following critical parameters:

• Reverse standoff voltage tolerance and breakdown voltage range
• Maximum clamping voltage at peak pulse current
• Peak pulse current capability
• Peak pulse power dissipation
• Operating temperature range
• Package compatibility (TO-277A SMPC)
• Automotive grade and AEC-Q101 qualification
• Surface mount mounting type

The TPC13AHM3_A/I qualifies as a substitute based on matching these core criteria within acceptable engineering tolerances. Both components belong to the PAR® and eSMP® series from Vishay, share identical package specifications, and maintain equivalent thermal and electrical performance characteristics for automotive transient protection applications.

Parameter Comparison

Engineering Selection Recommendations

The TPC13AHM3_A/I is the designated substitute for the obsolete TPC13HM3/87A. Both components maintain identical automotive grade classification and AEC-Q101 qualification, ensuring compliance with automotive reliability standards. The substitute part is currently in active production status, providing supply continuity and long-term availability.

Electrical parameter variations between the two parts are within acceptable ranges for TVS diode applications. The TPC13AHM3_A/I exhibits a slightly higher reverse standoff voltage (11.1V vs. 10.5V) and marginally lower clamping voltage (18.2V vs. 19V), with correspondingly higher peak pulse current capability (82.4A vs. 78.9A). These differences remain within the operational envelope for transient voltage suppression in automotive circuits.

Both components share identical thermal operating ranges, package specifications, and surface mount compatibility. The primary distinction is packaging format: the main part is supplied in bulk, while the substitute is available in Tape & Reel format, which is standard for high-volume production environments.

Frequently Asked Questions (FAQ)

Q: Can TPC13AHM3_A/I directly replace TPC13HM3/87A in existing designs?

A: Yes. Both components share identical package specifications (TO-277A SMPC), mounting type (surface mount), and thermal operating range (-65°C to 185°C). Electrical parameters are within acceptable substitution tolerances for TVS diode applications.

Q: What are the key electrical differences between these parts?

A: The TPC13AHM3_A/I has a reverse standoff voltage of 11.1V compared to 10.5V in the main part, and a maximum clamping voltage of 18.2V versus 19V. The substitute offers higher peak pulse current (82.4A vs. 78.9A). Peak pulse power dissipation remains identical at 1500W for both components.

Q: Are both parts automotive qualified?

A: Yes. Both the TPC13HM3/87A and TPC13AHM3_A/I carry automotive grade classification and AEC-Q101 qualification, meeting automotive reliability and quality standards.

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

A: Bulk packaging is suitable for small-quantity applications and manual assembly. Tape & Reel packaging is designed for automated pick-and-place assembly in high-volume production environments. Both formats contain the same component.

Q: Why is the main part listed as obsolete?

A: The TPC13HM3/87A is no longer in active production. The TPC13AHM3_A/I serves as the active production equivalent, ensuring continued availability and supply chain stability.

Q: Are there any compliance or certification differences?

A: No. Both components are ROHS3 compliant, REACH unaffected, and carry identical MSL ratings (1 - Unlimited). Compliance profiles are equivalent.
