Product details
Overview
TPSMP10AHM3_A/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMP (DO-220AA) package, designed for high-reliability automotive and industrial overvoltage protection. It features 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 on signal lines of automotive sensor units and microcontroller I/O interfaces.
For engineers reviewing the TPSMP10AHM3_A/H datasheet, TPSMP10AHM3_A/H pinout, TPSMP10AHM3_A/H application, or TPSMP10AHM3_A/H equivalent, key selection criteria include unidirectional polarity, 185 °C junction temperature capability, low-profile 1.0 mm height, MSL Level 1 reflow compatibility, and verified clamping performance under 10/1000 μs surge conditions.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with optimized junction passivation, enabling stable operation up to TJ = 185 °C and compliance with automotive reliability standards. Its unidirectional configuration provides precise reverse-biased clamping without forward conduction during normal operation.
The device delivers 300 W peak pulse power (10/1000 μs waveform) with low incremental surge resistance and fast response time, ensuring robust protection for sensitive ICs against ESD and load-dump transients. It is rated for 40 A non-repetitive forward surge current and exhibits only 5.0 μA maximum reverse leakage at VWM = 8.55 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 9.50 V / 10.5 V - defines reliable turn-on threshold for transient clamping |
| VWM | 8.55 V - maximum continuous reverse voltage before leakage exceeds 5.0 μA |
| VC @ IPPM | 20.7 V - clamped voltage during 20.7 A 10/1000 μs surge, limiting stress on downstream ICs |

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 | Higher VC = 16.0 V @ 17.1 A; lower PPPM = 400 W but larger SMA package (2.2 mm height) | Less suitable for ultra-low-profile automotive modules; better for industrial PCBs with higher surge margins | Select SMAJ10A only if board height >2.0 mm is acceptable and higher clamping voltage is tolerable |
| TPSMA6.8A | Lower VBR = 6.45–7.14 V; same SMP package; PPPM = 250 W; not rated for 185 °C operation | Limited to consumer/commercial temperature range (−65 °C to +150 °C); unsuitable for under-hood use | Choose TPSMA6.8A only for cost-sensitive non-automotive designs where 10 V clamping is excessive |
Compared with SMAJ10A and TPSMA6.8A, the TPSMP10AHM3_A/H uniquely combines AEC-Q101 qualification, 185 °C operation, 1.0 mm height, and 20.7 V clamping - making it the only option qualified for space- and temperature-constrained automotive signal-line protection.

FAQ
What is the clamping voltage of the TPSMP10AHM3_A/H under standard surge conditions?
The TPSMP10AHM3_A/H has a maximum clamping voltage (VC) of 20.7 V when subjected to its rated peak pulse current (IPPM) of 20.7 A using the 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and ensures downstream ICs remain within safe operating voltage limits during transient events. The TPSMP10AHM3_A/H maintains this clamping performance across its full operating temperature range.
Is the TPSMP10AHM3_A/H suitable for automotive under-hood applications?
Yes, the TPSMP10AHM3_A/H is AEC-Q101 qualified and rated for junction temperatures up to +185 °C, making it suitable for under-hood automotive applications such as engine control units and transmission control modules. Its SMP (DO-220AA) package supports reflow soldering at 260 °C (MSL Level 1), and its construction meets automotive humidity and thermal cycling requirements. The TPSMP10AHM3_A/H is explicitly designed for this environment.
What does the "HM3_A/H" suffix indicate in TPSMP10AHM3_A/H?
The "HM3" suffix denotes halogen-free, RoHS-compliant construction with matte tin-plated leads that meet JESD 201 Class 2 whisker resistance. The "A/H" indicates the revision code ("A") and packaging format ("H" = 7-inch tape and reel, 3000 units per reel). This suffix confirms compliance with automotive material standards and ensures traceable, controlled manufacturing per Vishay's eSMP® Series specifications. The TPSMP10AHM3_A/H carries this full designation on its marking and ordering documentation.
How does the TPSMP10AHM3_A/H compare to bidirectional TVS diodes in signal-line protection?
The TPSMP10AHM3_A/H is unidirectional and optimized for DC-biased lines like power rails and single-ended signal paths where reverse conduction must be avoided. Unlike bidirectional devices, it provides tighter VWM/VBR ratios (8.55 V / 9.5–10.5 V) and lower leakage (<5.0 μA), improving noise immunity. For AC-coupled or differential lines, a bidirectional variant would be required - but the TPSMP10AHM3_A/H excels where polarity-aware clamping is critical. Its design intent is explicit in Vishay's application guidance for automotive sensor interfaces.
What is the recommended PCB pad layout for the TPSMP10AHM3_A/H?
Vishay specifies a minimum pad layout of 5.0 mm × 5.0 mm copper area per terminal to achieve rated PPPM and thermal performance. The footprint must accommodate SMP (DO-220AA) dimensions: 3.61 mm × 2.18 mm body with 2.54 mm center-to-center lead spacing. Thermal relief and solder mask defined pads are advised to ensure manufacturability and mechanical reliability. These dimensions and layout rules are documented in the TPSMP10AHM3_A/H datasheet Figure 4 and are essential to realize the full 300 W surge rating. The TPSMP10AHM3_A/H requires this validated layout to meet spec.
