Product details
Overview
TPSMP9.1HE3/84A from Vishay General Semiconductor is a unidirectional automotive-grade transient voltage suppressor (TVS) in DO-220AA (SMP) package, with 9.1 V breakdown voltage (VBR), 21.7 V clamping voltage (VC) at 50 A peak pulse current, and 300 W peak pulse power rating for 10/1000 µs waveform. It provides robust ESD and surge protection for low-voltage signal lines in automotive sensor units and control modules.
For engineers reviewing the TPSMP9.1HE3/84A datasheet, TPSMP9.1HE3/84A pinout, TPSMP9.1HE3/84A application, or TPSMP9.1HE3/84A equivalent, key selection criteria include its AEC-Q101 qualification, 1.0 mm profile for space-constrained PCB layouts, low incremental surge resistance, and verified clamping performance under IPPM = 50 A.
Technical Context
The TPSMP9.1HE3/84A employs Vishay's patented PAR oxide-passivated chip construction to achieve stable breakdown characteristics and excellent clamping linearity. Its unidirectional configuration supports DC-biased signal lines where reverse conduction must be blocked.
Designed for automotive environments, it operates across –65 °C to +185 °C junction temperature range and meets MSL Level 1 per J-STD-020 with 260 °C lead-free reflow compatibility. The device delivers consistent surge response with <1 ns typical response time and low thermal resistance due to optimized die attach and SMP package geometry.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ9.0A | Higher VBR (9.0 V min), same DO-214AC package but 2.2 mm height; 200 W PPPM. | Lacks AEC-Q101 qualification; rated for commercial/industrial use only. | Select when automotive qualification is not required and board height budget permits 2.2 mm profile. |
| TPSMP9.0AHE3/84A | Lower VBR (8.65–9.55 V), identical DO-220AA package, same 300 W rating, and AEC-Q101 compliance. | Narrower VBR tolerance (±5 % vs. ±10 % for TPSMP9.1HE3/84A) suits tighter voltage margin designs. | Prefer for systems requiring tighter clamping onset precision, especially with 8.5–9.0 V nominal rails. |
Compared with SMAJ9.0A and TPSMP9.0AHE3/84A, the TPSMP9.1HE3/84A offers optimal balance of automotive qualification, ultra-low profile, and predictable clamping at 9.1 V nominal breakdown-critical for modern 12 V automotive domains where space and reliability are non-negotiable.
