Product details
Overview
TPSMA10AHE3_B/H from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor in SMA (DO-214AC) package, rated for 10 V breakdown voltage (VBR = 9.5–10.5 V at 1.0 mA), 400 W peak pulse power (10/1000 µs), and 185 °C maximum junction temperature. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power supply rails against lightning-induced surges and inductive switching transients.
For engineers reviewing the TPSMA10AHE3_B/H datasheet, TPSMA10AHE3_B/H pinout, TPSMA10AHE3_B/H application, or TPSMA10AHE3_B/H equivalent, key selection criteria include clamping voltage (VC = 27.6 V at IPPM), unidirectional polarity, AEC-Q101 qualification, and MSL Level 1 reflow compatibility up to 260 °C.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with optimized junction passivation for stable clamping under high-temperature operation (TJ up to 185 °C). Its low incremental surge resistance and fast response time enable effective suppression of sub-microsecond transients on DC power and signal paths.
The device operates exclusively in unidirectional mode with cathode band marking, and its 400 W peak pulse power rating is defined per 10/1000 µs waveform at 0.01 % duty cycle. Thermal derating follows Fig. 2 in the datasheet, with full power valid only at TA ≤ 25 °C on specified 5.0 mm × 5.0 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 9.5 V / 10.0 V / 10.5 V at 1.0 mA - defines precise voltage threshold where avalanche conduction begins under controlled test conditions |
| VWM | 8.65 V - maximum continuous reverse working voltage before leakage exceeds 5.0 µA at 25 °C |
| VC @ IPPM | 27.6 V - clamping voltage during 400 W surge event, limiting downstream voltage stress |
| PPPM | 400 W - peak pulse power handling capability with 10/1000 µs waveform, critical for IEC 61000-4-5 compliance margin |
| TJ max. | +185 °C - enables use in under-hood automotive environments and high-power industrial enclosures without thermal derating penalties |
| Polarity | Unidirectional - blocks reverse current only; requires correct orientation relative to protected circuit's ground reference |
| MSL Level | Level 1 per J-STD-020 - supports standard SMT reflow profiles up to 260 °C peak without preconditioning |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, molded plastic case meeting UL 94 V-0; cathode indicated by color band; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Surge current sink | Connected to protected line (e.g., +12 V rail); conducts during overvoltage events to shunt energy to ground |
| Cathode | Reference terminal / Ground return path | Connected to system ground or low-impedance return; establishes clamping reference and defines unidirectional behavior |
Key Features
| Feature | Design Value |
|---|---|
| Junction passivation optimized design | Enables stable VBR and low leakage (<5 µA at VWM) across -65 °C to +185 °C operating range |
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per AEC specification |

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 | Same SMA package, 400 W PPPM, but VBR = 11.1–12.3 V (min/typ/max), VC = 16.7 V; not AEC-Q101 qualified | Higher clamping voltage margin but lacks automotive qualification; suitable for commercial-grade industrial power supplies | Select SMAJ10A only when AEC-Q101 is not required and higher VBR tolerance is acceptable for system margin |
| TPSMA10AHM3_B/H | Identical electrical specs and AEC-Q101 qualification; differs only in halogen-free molding compound (HM3 vs HE3) | No functional difference; HM3 variant required for RoHS-compliant, halogen-free manufacturing programs | Choose TPSMA10AHM3_B/H if halogen-free compliance is mandated by your environmental policy or customer requirement |
Compared with SMAJ10A and TPSMA10AHM3_B/H, the TPSMA10AHE3_B/H provides identical surge performance and automotive qualification with standard RoHS compliance-making it optimal for cost-sensitive AEC-Q101 designs where halogen-free material is not mandatory.

FAQ
What is the breakdown voltage tolerance of TPSMA10AHE3_B/H?
The TPSMA10AHE3_B/H has a breakdown voltage (VBR) range of 9.5 V to 10.5 V at 1.0 mA test current, corresponding to ±5 % around the nominal 10.0 V rating. This tight tolerance ensures predictable clamping onset across production lots and temperature extremes, critical for precision overvoltage protection in automotive ECUs where margin to system operating voltage must be tightly controlled. The TPSMA10AHE3_B/H maintains this spec across its full -65 °C to +185 °C junction temperature range.
Is TPSMA10AHE3_B/H compatible with lead-free reflow soldering?
Yes, the TPSMA10AHE3_B/H is fully compatible with lead-free reflow soldering and meets MSL Level 1 per J-STD-020, allowing exposure to peak temperatures up to 260 °C without preconditioning. Its matte tin-plated terminals comply with J-STD-002 and JESD 22-B102, and the device has passed JESD 201 Class 2 whisker testing. This makes the TPSMA10AHE3_B/H suitable for high-volume SMT assembly in automotive and industrial manufacturing lines using standard Pb-free profiles.
Does TPSMA10AHE3_B/H meet AEC-Q101 requirements?
Yes, the TPSMA10AHE3_B/H is explicitly AEC-Q101 qualified, as confirmed by the "HE3" suffix in its ordering code and documented in Vishay's official datasheet (Document Number: 88405, Revision: 23-Jan-2024). Qualification includes stress tests for temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge (ESD), ensuring reliability for automotive under-hood and body-control module applications. The TPSMA10AHE3_B/H is not just rated for 185 °C-it is validated to operate continuously at that junction temperature per AEC-Q101.
What is the clamping voltage of TPSMA10AHE3_B/H at its rated surge current?
The clamping voltage (VC) of the TPSMA10AHE3_B/H is 27.6 V measured at its peak pulse current (IPPM) of approximately 14.5 A, corresponding to the 400 W rating under a 10/1000 µs waveform. This value is guaranteed maximum per the datasheet's Electrical Characteristics table and reflects worst-case voltage seen by protected circuitry during a full-rated surge event. The TPSMA10AHE3_B/H achieves this with a clamping ratio (VC/VBR) of ~2.76, indicating efficient energy diversion without excessive voltage overshoot.
Can TPSMA10AHE3_B/H replace TPSMA10AHM3_B/H in a design?
Yes, the TPSMA10AHE3_B/H can directly replace TPSMA10AHM3_B/H in most designs, as both share identical electrical specifications, AEC-Q101 qualification, and SMA (DO-214AC) mechanical form factor. The only difference is material composition: HE3 uses standard RoHS-compliant molding compound, while HM3 adds halogen-free certification. Unless halogen-free compliance is contractually required, the TPSMA10AHE3_B/H offers equivalent protection performance and is fully interchangeable in layout and function.
