Equivalent & Substitute Parts for TPSMC30HE3_A/I

Part Overview

The TPSMC30HE3_A/I is a unidirectional transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. It features a 24.3V reverse standoff voltage, 43.5V clamping voltage, and a peak pulse power rating of 1500W in a DO-214AB (SMCJ) surface-mount package. The current part status is "Obsolete," making it necessary to identify equivalent substitute models to maintain supply, compliance, and design continuity in applications where this device was utilized.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are selected exclusively based on the following explicit key parameters: device type (Zener, unidirectional), voltage ratings (reverse standoff, breakdown, clamping), peak pulse current, peak pulse power, package style (SMC/DO-214AB, SMA/DO-214AC), mounting method, and compliance criteria (RoHS, AEC-Q101 if applicable, MSL, ECCN). The substitute grouping is limited to parts provided in the input list, each meeting or closely matching the principal electrical and mechanical attributes.

Parameter Comparison

Engineering Selection Recommendations

Selection from substitute TVS diode models is determined by product status and compliance information. TPSMC30AHE3_B/I from Vishay General Semiconductor - Diodes Division is "Active" and maintains automotive AEC-Q101 qualification, full RoHS3 compliance, and identical mounting and package. SMCJ24A by EVVO Semi is "Active" and RoHS3 compliant, with surface-mount capability. When the original part is obsolete, selection must use parts that are "Active," meet stated compliance standards, and match specified electrical/mechanical parameters as listed.

Frequently Asked Questions (FAQ)

Q1: What key parameters should be matched when selecting a substitute for TPSMC30HE3_A/I?
A1: Voltage ratings (reverse standoff, breakdown, clamping), peak pulse power, peak pulse current, package/case style, mounting type, unidirectional channel count, RoHS compliance, qualification (e.g., AEC-Q101 automotive), and MSL.

Q2: Are package differences between DO-214AB and DO-214AC relevant for substitution?
A2: Yes, package style and supplier device package must be considered for mechanical and layout compatibility when selecting a substitute.

Q3: Does substitute part SMCJ24A meet automotive qualification requirements?
A3: Only data explicitly confirming AEC-Q101 qualification is referenced. SMCJ24A lacks stated grade or qualification.

Q4: Can I substitute an obsolete part with a part that has different voltage or current ratings?
A4: Substitution must be based strictly on the provided key parameters. Only substitutions listed in the provided input are permitted.

Q5: Which substitute parts maintain RoHS3 and ECCN EAR99 compliance?
A5: All listed substitutes, TPSMC30AHE3_B/I and SMCJ24A, are RoHS3 Compliant and assigned ECCN EAR99 per provided data.
