Product details
Overview
TPSMP13AHM3_A/I 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 12.4 V to 13.7 V breakdown voltage (VBR), 11.1 V stand-off voltage (VWM), 400 W peak pulse power (PPPM), 185 °C maximum junction temperature, and SMP (DO-220AA) package with 1.0 mm typical height - deployed to protect sensor signal lines and drive transistors against ESD and lightning-induced surges.
For engineers reviewing the TPSMP13AHM3_A/I datasheet, TPSMP13AHM3_A/I pinout, TPSMP13AHM3_A/I application, or TPSMP13AHM3_A/I equivalent, key selection criteria include its AEC-Q101 qualification, unidirectional polarity, low incremental surge resistance, 22.0 A peak pulse current (IPPM), and clamping voltage of 18.2 V at rated surge - critical for robust front-end protection in automotive ECUs and industrial I/O modules.
Technical Context
The TPSMP13AHM3_A/I employs passivated anisotropic rectifier technology optimized for high-power-density transient suppression. Its junction passivation enables stable operation up to TJ = 185 °C and supports MSL Level 1 reflow compatibility (260 °C peak).
It delivers fast response time (<1 ns) and low clamping ratio (VC/VBR ≈ 1.42), with a 10/1000 μs waveform rating and derating per ambient temperature per Figure 2. The device is strictly unidirectional and requires cathode-band orientation during PCB layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V - defines reliable avalanche initiation range under 1 mA test current |
| VWM | 11.1 V - maximum reverse voltage before leakage exceeds 1 μA, ensuring no false triggering |
| PPPM | 400 W - peak surge power handling capability with 10/1000 μs waveform on standard PCB pads |
| IPPM | 22.0 A - maximum non-repetitive surge current the device safely clamps without failure |
| VC @ IPPM | 18.2 V - clamped voltage during full-rated surge, limiting downstream IC stress |
| TJ max. | 185 °C - enables operation in under-hood automotive environments and high-ambient industrial enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A | Higher VC (21.5 V), lower PPPM (400 W same but derates faster), SMA package (2.5 mm height) | Less suitable for space-constrained automotive modules due to taller profile and reduced thermal margin at 185 °C | Choose SMAJ13A only if legacy SMA footprint reuse is required and thermal derating is acceptable. |
| TPSMA6.8A | Lower VBR (6.45–7.14 V), lower PPPM (250 W), same SMP package but not AEC-Q101 qualified | Not approved for automotive use; limited to consumer/industrial applications where qualification is not mandated | Select TPSMA6.8A only for cost-sensitive non-automotive designs requiring lower clamping voltage. |
Compared with SMAJ13A and TPSMA6.8A, the TPSMP13AHM3_A/I offers superior thermal capability (185 °C vs. 150 °C), automotive qualification, and lower profile - making it the preferred choice for next-generation automotive sensor nodes and high-density industrial controllers where reliability and space are co-constrained.

FAQ
What is the exact breakdown voltage range for TPSMP13AHM3_A/I?
The TPSMP13AHM3_A/I has a guaranteed breakdown voltage (VBR) range of 12.4 V to 13.7 V when tested at 1.0 mA, per the Vishay datasheet Document Number 88471. This range ensures consistent avalanche initiation across production lots and supports precise system-level overvoltage threshold design. The TPSMP13AHM3_A/I is specified at TA = 25 °C with square-wave pulse testing per ANSI/IEEE C62.35 standards.
Is TPSMP13AHM3_A/I suitable for automotive applications?
Yes, the TPSMP13AHM3_A/I is AEC-Q101 qualified and rated for TJ = -65 °C to +185 °C, making it fully suitable for under-hood and body-control automotive applications. Its construction meets JESD201 Class 2 whisker resistance, MSL Level 1 reflow compatibility, and halogen-free RoHS compliance - all verified per Vishay's qualification report for the HM3 suffix. The TPSMP13AHM3_A/I is explicitly designated as automotive grade in the datasheet.
What is the clamping voltage of TPSMP13AHM3_A/I at its rated surge current?
The TPSMP13AHM3_A/I exhibits a maximum clamping voltage (VC) of 18.2 V when subjected to its rated peak pulse current (IPPM) of 22.0 A under a 10/1000 μs waveform. This value is measured at TA = 25 °C on a PCB with 5.0 mm × 5.0 mm copper pads per terminal. The TPSMP13AHM3_A/I maintains this clamping performance with minimal degradation up to its 185 °C junction limit.
Does TPSMP13AHM3_A/I have bidirectional capability?
No, the TPSMP13AHM3_A/I is strictly unidirectional. Its electrical characteristics - including VBR, VWM, and IPPM - are defined only for reverse-bias operation, with polarity indicated by a cathode color band. Bidirectional behavior is not characterized or guaranteed. For AC-line or differential-signal protection requiring symmetrical clamping, a dedicated bidirectional TVS such as the TPSMP13CA must be selected instead of the TPSMP13AHM3_A/I.
What package type and dimensions does TPSMP13AHM3_A/I use?
The TPSMP13AHM3_A/I uses the SMP (DO-220AA) package: a compact, surface-mount outline measuring 3.61 mm × 2.18 mm × 1.0 mm (L × W × H), with 0.61 mm lead width and 2.54 mm center-to-center terminal spacing. It features matte tin-plated leads compliant with J-STD-002 solderability and JESD22-B102 wetting balance testing. The TPSMP13AHM3_A/I's SMP footprint is distinct from SMA or SMC and requires dedicated land pattern per Vishay's recommended pad layout.
