Overview
TPSMB13AHM3_A/H from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) designed for clamping inductive switching surges and lightning-induced transients on power rails and signal lines. It features a 13.0 V nominal breakdown voltage (VBR), 11.1 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 µs), 18.2 V maximum clamping voltage at 33 A, and operates up to +185 °C junction temperature - deployed in automotive power supply protection and industrial sensor interface circuits.
For engineers reviewing the TPSMB13AHM3_A/H datasheet, TPSMB13AHM3_A/H pinout, TPSMB13AHM3_A/H application, or TPSMB13AHM3_A/H equivalent, this page delivers verified electrical parameters, SMB (DO-214AA) package mapping, AEC-Q101 qualification status, thermal derating curves, and direct alternative part comparisons for high-reliability overvoltage protection design.
Technical Context
The TPSMB13AHM3_A/H uses passivated anisotropic rectifier technology to achieve low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of ESD and load-dump transients before sensitive downstream ICs are damaged. Its unidirectional polarity and cathode-band marking align with standard SMB PCB layout conventions.
Rated for 75 A non-repetitive forward surge current (IFSM) and 33 A peak pulse current (IPPM) at 10/1000 µs, it maintains stable VBR across -65 °C to +185 °C with a +0.072 %/°C temperature coefficient - critical for under-hood automotive environments where thermal drift must be minimized.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A | Same SMB package, 13 V VBR, but rated for 600 W only at 10/1000 µs; not AEC-Q101 qualified; higher VC = 21.5 V | Lacks automotive qualification and has 3.3 V higher clamping voltage - unsuitable for tight-margin 12 V systems | Select TPSMB13AHM3_A/H when AEC-Q101 compliance and lower clamping are required; choose SMBJ13A only for cost-sensitive consumer designs. |
| TPSMB13AHE3_A/H | Identical electrical specs and AEC-Q101 qualification; differs only in termination - HE3 suffix is RoHS-compliant with standard tin plating, HM3 is halogen-free | No functional difference; HM3 meets stricter environmental mandates (e.g., JESD201 Class 2 whisker resistance) | Choose TPSMB13AHM3_A/H for halogen-free compliance and enhanced whisker resistance; use HE3 version if halogen content is unrestricted. |
