Overview
TPSMP10AHM3_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 circuit protection. It features a 9.5 V to 10.5 V breakdown voltage (VBR), 8.55 V stand-off voltage (VWM), 20.7 V clamping voltage at 20.7 A peak pulse current, 300 W peak pulse power rating, and AEC-Q101 qualification - deployed to safeguard signal lines and ICs in engine control units and sensor interfaces.
For engineers reviewing the TPSMP10AHM3_A/I datasheet, TPSMP10AHM3_A/I pinout, TPSMP10AHM3_A/I application, or TPSMP10AHM3_A/I equivalent, key selection criteria include its DO-220AA (SMP) package, 185 °C junction temperature rating, low-profile 1.0 mm height, unidirectional polarity with cathode band marking, and compliance with JESD201 Class 2 whisker testing and MSL Level 1 reflow requirements.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for fast response (<1 ns) and low incremental surge resistance, enabling robust suppression of ESD and lightning-induced transients per IEC 61000-4-2/4-5. Its unidirectional configuration supports DC-biased signal and power rail protection without reverse conduction during normal operation.
The device operates across -65 °C to +185 °C, with thermal derating defined per Figure 2 and validated on FR-4 PCB using 5.0 mm × 5.0 mm copper pads per terminal. Clamping performance is specified under 10/1000 µs waveform conditions, with VF = 2.5 V at 25 A forward surge and IR ≤ 5.0 µA at VWM.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | DO-214AC (SMA) package; 1.8 mm height; 200 W PPPM; VC = 16.0 V @ 17.4 A; no AEC-Q101 qualification. | Lower power rating and non-automotive qualification limit use to consumer/industrial boards without automotive lifecycle requirements. | Select SMAJ10A only for cost-sensitive non-automotive designs where 200 W surge capacity suffices and board height >1.0 mm is acceptable. |
| TPSMD10A | DO-218AB (SMC) package; 2.6 mm height; 400 W PPPM; VC = 16.7 V @ 23.9 A; AEC-Q101 qualified; higher thermal mass. | Greater surge handling but larger footprint and height - unsuitable for ultra-thin modules like camera PCBs. | Choose TPSMD10A when system-level surge tests exceed 300 W or when thermal dissipation demands larger copper area and higher mounting pad mass. |
Compared with SMAJ10A and TPSMD10A, the TPSMP10AHM3_A/I uniquely balances AEC-Q101 compliance, 300 W surge capability, and 1.0 mm profile - making it the only option among the three suitable for space-constrained automotive modules requiring full qualification and mid-range power handling.

FAQ
What is the clamping voltage of the TPSMP10AHM3_A/I under standard test conditions?
The TPSMP10AHM3_A/I has a maximum clamping voltage (VC) of 20.7 V when subjected to its rated peak pulse current (IPPM = 20.7 A) under the standardized 10/1000 µs waveform. This value is measured at TA = 25 °C with specified PCB mounting conditions (5.0 mm × 5.0 mm copper pads), and ensures downstream ICs remain within safe operating voltage limits during surge events.
Is the TPSMP10AHM3_A/I suitable for automotive applications?
Yes, the TPSMP10AHM3_A/I is AEC-Q101 qualified and rated for operation from -65 °C to +185 °C, making it suitable for under-hood and cabin automotive applications. Its HM3 suffix confirms compliance with JESD201 Class 2 whisker testing, UL 94 V-0 flammability, and MSL Level 1 reflow - all required for modern automotive electronics production.
What does the "HM3_A/I" suffix indicate in TPSMP10AHM3_A/I?
The "HM3" denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification and JESD201 Class 2 whisker resistance. "A" is the revision code; "I" specifies packaging in 13-inch tape-and-reel format with 10,000 units per reel - distinct from "H" (7-inch reel, 3,000 units) used in other variants of the same base part.
How does the TPSMP10AHM3_A/I compare to bidirectional TVS diodes?
The TPSMP10AHM3_A/I is unidirectional and intended for DC-biased lines such as power rails or single-ended signals referenced to ground. Unlike bidirectional devices, it blocks reverse voltage up to -8.55 V but conducts only in one direction during clamping - providing lower leakage and tighter VBR tolerance than equivalent bidirectional parts, which is critical in precision analog and automotive power domains.
What is the maximum steady-state power dissipation for the TPSMP10AHM3_A/I?
The TPSMP10AHM3_A/I has a maximum steady-state power dissipation (PD) of 2.5 W when mounted on an infinite heatsink at TA = 75 °C. On standard FR-4 PCB with recommended pad layout, derating applies per Figure 6 in the datasheet - actual usable DC power is limited to ~0.5 W at 100 °C ambient due to thermal resistance constraints.
