TPSMC11HE3_A/I Equivalent & Substitute Parts

Part Overview

The TPSMC11HE3_A/I is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This component is designed for surface mount applications in the DO-214AB (SMC) package and provides transient overvoltage protection with a 9.4V reverse standoff voltage and 15.6V maximum clamping voltage. The part is classified as obsolete, making identification of active equivalent alternatives essential for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution of the TPSMC11HE3_A/I is determined by strict equivalence across the following critical electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 9.4V
• Voltage - Breakdown (Min): 10.5V
• Voltage - Clamping (Max) @ Ipp: 15.6V
• Current - Peak Pulse (10/1000µs): 96.2A
• Power - Peak Pulse: 1500W
• Unidirectional Channels: 1
• Package / Case: DO-214AB, SMC
• Operating Temperature Range: -65°C to 185°C (TJ)
• Grade: Automotive
• Qualification: AEC-Q101

The TPSMC11AHE3_B/I meets all these criteria and is classified as an active product, making it a direct functional equivalent suitable for replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The TPSMC11AHE3_B/I is the direct equivalent for the obsolete TPSMC11HE3_A/I. Both parts are manufactured by Vishay General Semiconductor - Diodes Division and share identical electrical specifications, thermal operating range, and automotive-grade qualification (AEC-Q101). The substitute part maintains ROHS3 compliance and MSL Level 1 rating.

The primary distinction is product status: the TPSMC11HE3_A/I is obsolete, while the TPSMC11AHE3_B/I is active. The substitute part is available in Tape & Reel (TR) packaging, which is standard for production environments. Both parts are functionally interchangeable in circuit applications requiring 9.4V standoff protection with 96.2A peak pulse current handling in the DO-214AB surface mount package.

Frequently Asked Questions (FAQ)

Q: Can the TPSMC11AHE3_B/I be used as a direct replacement for the TPSMC11HE3_A/I?

A: Yes. Both parts are identical in electrical performance, thermal range, package type, and automotive qualification. The substitute part is active and currently available.

Q: What is the difference between the two part numbers?

A: The TPSMC11HE3_A/I is obsolete, while the TPSMC11AHE3_B/I is active. The suffix designations (_A/I versus _B/I) indicate different manufacturing revisions or packaging configurations, but electrical and mechanical specifications remain equivalent.

Q: Are there packaging differences between these parts?

A: Both parts use the DO-214AB (SMC) surface mount package. The TPSMC11AHE3_B/I is supplied in Tape & Reel (TR) format, which is standard for automated assembly. The TPSMC11HE3_A/I packaging format was not specified in the available data.

Q: Is the TPSMC11AHE3_B/I suitable for automotive applications?

A: Yes. The substitute part carries automotive-grade classification and AEC-Q101 qualification, meeting the same standards as the original part.

Q: What are the critical parameters for substitution?

A: Substitution is valid when the following parameters match: reverse standoff voltage (9.4V), breakdown voltage (10.5V minimum), clamping voltage (15.6V maximum), peak pulse current (96.2A), power rating (1500W), operating temperature range (-65°C to 185°C), and package type (DO-214AB, SMC).
