TPSMA16HE3_A/I Equivalent & Substitute Parts Reference

Part Overview

The TPSMA16HE3_A/I, manufactured by Vishay General Semiconductor - Diodes Division, is an automotive-grade transient voltage suppressor (TVS) diode. It features a 12.9V reverse standoff voltage, 23.5V clamping voltage, and is rated for 17A peak pulse current with a 400W peak pulse power, housed in a DO-214AC (SMA) surface-mount package. The part is obsolete, which makes the identification of alternative models with equivalent parameters essential for maintaining form, fit, and function in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution is determined strictly by the alignment of electrical parameters, package form factor, automotive grade, and compliance status. The acceptable substitute must match or closely align with the following parameters: Type, unidirectional channel count, reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current, peak pulse power, automotive qualification (AEC-Q101), RoHS and REACH compliance, mounting type, package/case, and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

TPSMA16HE3_A/I is obsolete. TPSMA16AHE3_B/I is active, automotive grade, AEC-Q101 qualified, ROHS3 compliant, and REACH unaffected. It shares the same series, package, mounting type, and critical environmental qualifications as the original part.

Frequently Asked Questions (FAQ)

Q: What are the main criteria for selecting a substitute for TPSMA16HE3_A/I?
A: Substitute selection is based strictly on matching or closely aligning electrical parameters, package type, automotive certification, and compliance status.

Q: Is TPSMA16AHE3_B/I form and footprint compatible with TPSMA16HE3_A/I?
A: Both devices use the DO-214AC (SMA) surface-mount package and have the same mounting type.

Q: Does the automotive and environmental compliance match between main and substitute parts?
A: Both parts are automotive grade, AEC-Q101 qualified, ROHS3 compliant, and REACH unaffected.

Q: Are there differences in voltage or current ratings between the two parts?
A: TPSMA16AHE3_B/I has a slightly higher reverse standoff and breakdown voltage, a lower clamping voltage, and a higher peak pulse current, all other key parameters are consistent.

Q: Can TPSMA16AHE3_B/I be used in applications requiring RoHS and REACH compliance?
A: TPSMA16AHE3_B/I is ROHS3 compliant and REACH unaffected, aligning with environmental compliance requirements.
