Product details
Overview
TPSMC15HE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, designed for clamping voltage transients on power and signal lines. It features 13.5 V to 16.5 V breakdown voltage (VBR), 12.1 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 µs), 68.2 A peak pulse current (IPPM), and 22 V maximum clamping voltage (VC) - used to protect MOSFETs and ICs in automotive power supplies.
For engineers reviewing the TPSMC15HE3_A/H datasheet, TPSMC15HE3_A/H pinout, TPSMC15HE3_A/H application, or TPSMC15HE3_A/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 185 °C junction temperature rating, DO-214AB mechanical compatibility, and clamping performance under 10/1000 µs surge conditions.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology with junction passivation optimized for high-reliability operation. Its unidirectional structure provides low incremental surge resistance and fast response time to suppress transients induced by inductive load switching or lightning surges.
Rated for TJ = –65 °C to +185 °C, it meets MSL Level 1 per J-STD-020 and passes JESD201 Class 2 whisker testing. The device is RoHS-compliant and qualified to AEC-Q101, making it suitable for under-hood automotive electronics where thermal stability and long-term reliability are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 13.5 V / 16.5 V - ensures reliable turn-on above normal operating voltage while avoiding false triggering during line ripple. |
| VWM | 12.1 V - maximum continuous reverse working voltage compatible with 12 V automotive systems. |
| VC @ IPPM | 22 V - clamps 10/1000 µs surge to safe level for downstream 24 V-rated components. |
| PPPM | 1500 W - handles high-energy transients such as ISO 7637-2 Pulse 1 and Pulse 2b without degradation. |
| IPPM | 68.2 A - peak surge current capability validated at 25 °C with 0.31" × 0.31" copper pads. |
| TJ max. | +185 °C - enables placement near heat sources (e.g., engine control units) without derating concerns. |
| Polarity | Unidirectional - protects against positive-going transients only; requires correct orientation relative to DC bias. |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, matte tin-plated leads, cathode indicated by color band. Meets UL 94 V-0 flammability rating and J-STD-002 solderability requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction | Connected to lower-potential side of protected line; defines unidirectional clamping direction. |
| Cathode | Current exit terminal during forward conduction; marked with band | Connected to higher-potential side (e.g., battery rail); determines polarity-sensitive placement on PCB. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A | DO-214AC (SMA) package; 15 V VWM; 24.4 V VC; 1000 W PPPM; same AEC-Q101 qualification. | Lower power handling and larger VC margin reduce protection margin in high-energy automotive transients. | Select SMAJ15A only if board space constraints require smaller footprint and surge energy is limited to ≤1000 W. |
| TPSMC15AHE3_A/H | Same DO-214AB package; tighter VBR tolerance (±5 % vs. ±10 %); 14.3–15.8 V VBR; 21.2 V VC. | Narrower breakdown range improves consistency across production lots but offers no advantage in non-critical clamping applications. | Choose TPSMC15AHE3_A/H when design requires guaranteed VBR matching across units, e.g., in precision voltage reference protection. |
Compared with SMAJ15A and TPSMC15AHE3_A/H, the TPSMC15HE3_A/H delivers higher surge power headroom (1500 W vs. 1000 W), lower clamping voltage (22 V vs. 24.4 V), and broader VBR tolerance - making it optimal for cost-sensitive, high-reliability automotive power rail protection where exact VBR matching is secondary to robustness.

FAQ
What is the breakdown voltage range of the TPSMC15HE3_A/H?
The TPSMC15HE3_A/H has a specified breakdown voltage (VBR) range of 13.5 V to 16.5 V at 1 mA test current, per the Vishay datasheet revision 22-Jul-16. This ±10 % tolerance allows robust operation across manufacturing variance while ensuring reliable clamping above typical 12 V system rails. The TPSMC15HE3_A/H maintains this specification across its full operating temperature range.
Is the TPSMC15HE3_A/H suitable for automotive applications?
Yes, the TPSMC15HE3_A/H is AEC-Q101 qualified and rated for junction temperatures up to +185 °C, making it suitable for under-hood automotive applications including engine control units, body control modules, and ADAS power supplies. Its DO-214AB package, MSL Level 1 rating, and 1500 W surge capability align with ISO 7637-2 and ISO 16750-2 requirements. The TPSMC15HE3_A/H is explicitly listed in Vishay's automotive-grade product portfolio.
What is the maximum clamping voltage of the TPSMC15HE3_A/H at peak pulse current?
The TPSMC15HE3_A/H exhibits a maximum clamping voltage (VC) of 22 V at its rated peak pulse current (IPPM) of 68.2 A, measured under the standard 10/1000 µs waveform condition. This value is guaranteed at TA = 25 °C with 0.31" × 0.31" copper pads per terminal. The TPSMC15HE3_A/H maintains clamping performance across temperature due to its high-TJ design.
Does the TPSMC15HE3_A/H have unidirectional or bidirectional polarity?
The TPSMC15HE3_A/H is a unidirectional TVS diode, as confirmed in the Vishay datasheet section "FEATURES" and "PRIMARY CHARACTERISTICS". It protects against positive-going transients only and must be oriented with the cathode band toward the higher-potential side of the circuit. Bidirectional variants (e.g., TPSMC15CA) are separate part numbers and not interchangeable with the TPSMC15HE3_A/H.
What packaging and reel options are available for the TPSMC15HE3_A/H?
The TPSMC15HE3_A/H is supplied in 7" diameter plastic tape and reel format with a base quantity of 850 units per reel, designated by the "H" package code in the ordering part number. The "A/H" suffix indicates RoHS-compliant construction, AEC-Q101 qualification, and HE3 plating (matte tin, JESD201 Class 2 whisker tested). The TPSMC15HE3_A/H is not offered in bulk or tube packaging per Vishay's official ordering information.
