Product details
Overview
TPSMP30AHM3_A/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the PAR® family, designed for high-reliability automotive and industrial overvoltage protection. It features a 28.5 V to 31.5 V breakdown voltage (VBR), 41.4 V clamping voltage (VC) at 9.7 A peak pulse current, 400 W peak pulse power (10/1000 µs), 185 °C maximum junction temperature, and SMP (DO-220AA) package with 1.0 mm profile - deployed to protect sensor signal lines and drive transistors in ADAS ECUs.
For engineers reviewing the TPSMP30AHM3_A/H datasheet, TPSMP30AHM3_A/H pinout, TPSMP30AHM3_A/H application, or TPSMP30AHM3_A/H equivalent, this page delivers verified electrical ratings, AEC-Q101 qualification status, thermal derating behavior, clamping performance under surge conditions, and validated alternative parts for automotive-grade circuit protection design.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology optimized for low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of ESD and load-dump transients per ISO 16750-2. Its unidirectional polarity supports DC-biased signal line protection without reverse conduction during normal operation.
The device operates across -65 °C to +185 °C, meets MSL Level 1 per J-STD-020 (260 °C reflow peak), and is halogen-free, RoHS-compliant, and qualified to AEC-Q101 - confirming suitability for under-hood automotive electronics where thermal stability and long-term reliability are critical.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ30A | Lower PPPM (400 W vs. 400 W same), but higher VC (48.4 V), larger SMA package (2.5 mm height), no AEC-Q101 qualification | Not suitable for automotive under-hood use; limited to industrial/commercial environments with lower thermal demands | Select only if AEC-Q101 is not required and board height allows SMA footprint |
| TPSMA6.8A | Same SMP package, but lower VBR (6.45–7.14 V), lower PPPM (250 W), rated for 125 °C TJ max., AEC-Q101 qualified | Designed for 5 V logic protection; insufficient clamping margin for 24 V systems requiring ≥28.5 V VBR | Use only for low-voltage digital I/O protection; not interchangeable with TPSMP30AHM3_A/H due to VBR mismatch |
Compared with SMAJ30A and TPSMA6.8A, TPSMP30AHM3_A/H provides superior thermal robustness (185 °C vs. 150 °C/125 °C), automotive qualification, and identical 400 W surge rating - making it the sole choice for space-constrained, high-temperature 24 V automotive signal line protection.

FAQ
What is the clamping voltage of TPSMP30AHM3_A/H at its rated peak pulse current?
The TPSMP30AHM3_A/H has a maximum clamping voltage (VC) of 41.4 V when subjected to its rated peak pulse current (IPPM) of 9.7 A under the standard 10/1000 µs waveform. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on the protected circuit during surge events. The TPSMP30AHM3_A/H maintains this clamping performance across its full operating temperature range, supporting robust protection in automotive environments.
Is TPSMP30AHM3_A/H qualified for automotive applications?
Yes, TPSMP30AHM3_A/H is AEC-Q101 qualified and rated for operation from -65 °C to +185 °C, meeting stringent automotive reliability requirements including temperature cycling, highly accelerated life testing, and ESD immunity. Its SMP (DO-220AA) package is MSL Level 1 compliant for lead-free reflow, and the device is halogen-free and RoHS-compliant - fulfilling material compliance mandates for modern automotive ECUs and ADAS systems.
What is the standoff voltage rating for TPSMP30AHM3_A/H?
The reverse standoff voltage (VWM) for TPSMP30AHM3_A/H is 25.6 V - the maximum DC or continuous reverse voltage that can be applied without causing significant leakage current. This rating ensures the TPSMP30AHM3_A/H remains non-conductive during normal operation in 24 V automotive systems, activating only when transients exceed its 28.5–31.5 V breakdown range. VWM is specified at 25 °C and derates predictably with temperature.
Does TPSMP30AHM3_A/H have a unidirectional or bidirectional configuration?
TPSMP30AHM3_A/H is a unidirectional TVS diode, meaning it conducts only in one direction - from cathode to anode during reverse-biased transient events. Its polarity is marked by a cathode band, and it is intended for DC-biased protection applications such as 24 V supply rails or sensor signal lines referenced to ground. It does not provide symmetrical clamping for AC signals or bipolar transients.
What package type does TPSMP30AHM3_A/H use, and what are its key mechanical attributes?
TPSMP30AHM3_A/H uses the SMP (DO-220AA) package: a compact surface-mount outline measuring 3.61 mm × 2.18 mm with a typical height of 1.0 mm. It features matte tin-plated terminals compliant with J-STD-002 and JESD 22-B102, meets JESD 201 Class 2 whisker resistance, and carries a cathode band for polarity identification. The molding compound is UL 94 V-0 rated, supporting high-density automated placement and reflow compatibility.
