Product details
Overview
TPSMP36AHM3_A/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the eSMP® Series, designed for high-reliability automotive and industrial overvoltage protection. It features a 34.2 V to 37.8 V breakdown voltage (VBR), 30.8 V stand-off voltage (VWM), 400 W peak pulse power (10/1000 µs), 8.0 A peak pulse current (IPPM), and 185 °C maximum junction temperature - deployed to protect sensor signal lines and drive transistors in harsh environments.
For engineers reviewing the TPSMP36AHM3_A/I datasheet, TPSMP36AHM3_A/I pinout, TPSMP36AHM3_A/I application, or TPSMP36AHM3_A/I equivalent, key selection criteria include its AEC-Q101 qualification, DO-220AA (SMP) package with 1.0 mm profile, low incremental surge resistance, fast response time, and MSL Level 1 rating for lead-free reflow compatibility.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver stable clamping performance under repetitive surge stress. Its unidirectional polarity and 30.8 V stand-off voltage enable reliable operation in DC-biased signal paths where reverse leakage must remain below 1.0 µA at room temperature and 5.0 µA at 150 °C.
The device is optimized for automated SMT placement on FR-4 PCBs using 5.0 mm × 5.0 mm copper pads per terminal, with thermal derating defined up to 185 °C junction temperature and validated clamping voltage of 49.9 V at 8.0 A IPPM.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A-E3/57T | DO-214AC (SMA) package; 36.0–40.0 V VBR; 400 W PPPM; higher profile (2.29 mm) | Less suitable for ultra-thin modules; requires larger pad area and greater board clearance | Select when legacy SMA footprint compatibility is required and height constraint is relaxed |
| TPSMD36H | DO-218AB (SMC) package; same VBR range; 500 W PPPM; 2.6 mm height | Better surge margin but incompatible with compact layouts; not AEC-Q101 qualified | Choose for industrial power supplies needing higher energy absorption where automotive qualification is unnecessary |
Compared with SMAJ36A-E3/57T and TPSMD36H, the TPSMP36AHM3_A/I delivers identical clamping performance in a 1.0 mm profile with AEC-Q101 validation - making it optimal for next-generation automotive ECUs and space-limited industrial controllers where reliability and miniaturization are jointly critical.

Yes, TPSMP36AHM3_A/I meets J-STD-020 MSL Level 1 and is rated for lead-free reflow with a maximum peak temperature of 260 °C. Its matte tin-plated terminals and halogen-free molding compound ensure reliable solder joint formation without preconditioning or special handling.
Does TPSMP36AHM3_A/I have automotive qualification?
Yes, TPSMP36AHM3_A/I is AEC-Q101 qualified and categorized as automotive grade per Vishay documentation. It undergoes stress testing for temperature cycling, humidity, mechanical shock, and high-temperature operating life - confirming suitability for engine bay, chassis, and ADAS applications.
What is the maximum clamping voltage of TPSMP36AHM3_A/I at rated surge current?
The maximum clamping voltage (VC) of TPSMP36AHM3_A/I is 49.9 V when subjected to its rated 8.0 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is guaranteed across temperature and ensures protected ICs remain within safe operating limits during surge events.
How does the SMP (DO-220AA) package of TPSMP36AHM3_A/I compare to SMA or SMC packages?
The SMP (DO-220AA) package of TPSMP36AHM3_A/I offers a 1.0 mm typical height - less than half that of SMA (2.29 mm) and SMC (2.6 mm) - while maintaining 400 W surge capability. Its compact footprint and low thermal resistance make it ideal for dense layouts where vertical space is constrained, unlike larger alternatives.
