Product details
Overview
TPSMC15AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients on power and signal lines. It features 15 V nominal breakdown voltage (VBR = 14.3–15.8 V), 12.8 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 µs), <1 µA reverse leakage at VWM, and 21.2 V maximum clamping voltage (VC) at 70.8 A peak pulse current - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the TPSMC15AHE3_A/H datasheet, TPSMC15AHE3_A/H pinout, TPSMC15AHE3_A/H application, or TPSMC15AHE3_A/H equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C junction temperature rating, unidirectional polarity, low clamping ratio (VC/VBR ≈ 1.41), and RoHS-compliant matte tin-plated terminals suitable for J-STD-002 soldering.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology with junction passivation optimized for high-reliability operation under thermal stress. Its 185 °C maximum junction temperature and MSL Level 1 rating support reflow compatibility up to 260 °C peak, enabling use in under-hood automotive modules and industrial motor drives where sustained thermal cycling occurs.
The device delivers 1500 W peak pulse power per 10/1000 µs waveform with low incremental surge resistance and fast response time (<1 ns), ensuring effective suppression of ESD, load dump, and inductive switching transients before downstream components experience overvoltage stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 14.3 / 15.0 / 15.8 V - defines precise voltage threshold at which clamping initiates under 1 mA test current |
| VWM | 12.8 V - maximum continuous reverse operating voltage without significant leakage current |
| VC @ IPPM | 21.2 V at 70.8 A - clamped voltage during worst-case 1500 W transient, limiting stress on protected ICs |
| PPPM | 1500 W - peak pulse power handling capability with standard 10/1000 µs waveform per IEC 61000-4-5 |
| TJ max | +185 °C - enables operation in high-temperature environments such as engine control units and power converters |
| Polarity | Unidirectional - provides reverse-biased clamping only; requires correct orientation relative to DC bias |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15A | Same VBR range (14.3–15.8 V), but lower PPPM = 600 W and SMB (DO-214AA) package (smaller footprint, lower thermal mass) | Limited to lower-energy transients; unsuitable for automotive load dump or industrial motor drive snubbing | Select when space-constrained PCB layout prioritizes size over surge robustness and thermal endurance |
| TPSMC15AHM3_A/H | Identical electrical specs and SMC package; differs only in halogen-free molding compound (HM3 vs HE3) | No functional difference; HM3 required only where halogen-free compliance is mandated by OEM or regional regulation | Choose HM3 version if RoHS + halogen-free certification (e.g., IEC 61249-2-21) is contractually required |
Compared with SMBJ15A and TPSMC15AHM3_A/H, the TPSMC15AHE3_A/H offers superior surge handling (1500 W vs 600 W) and automotive qualification without halogen restrictions - making it optimal for high-reliability 12 V systems where thermal stability and AEC-Q101 validation are mandatory.

FAQ
What is the maximum clamping voltage of the TPSMC15AHE3_A/H at its rated peak pulse current?
The TPSMC15AHE3_A/H has a maximum clamping voltage (VC) of 21.2 V at its specified peak pulse current (IPPM) of 70.8 A, measured using the standard 10/1000 µs waveform. This value ensures that protected circuitry remains within safe voltage limits during high-energy transients. The TPSMC15AHE3_A/H maintains this clamping performance across its full operating temperature range, with minimal derating up to 185 °C junction temperature.
Is the TPSMC15AHE3_A/H qualified for automotive applications?
Yes, the TPSMC15AHE3_A/H is AEC-Q101 qualified, as confirmed by Vishay's documentation and ordering code suffix "HE3", which denotes RoHS-compliant and AEC-Q101-qualified variants. It undergoes rigorous stress testing including high-temperature reverse bias (HTRB), temperature cycling, and ESD verification - making the TPSMC15AHE3_A/H suitable for engine control units, body control modules, and ADAS sensor interfaces.
What is the stand-off voltage (VWM) of the TPSMC15AHE3_A/H, and why does it matter?
The TPSMC15AHE3_A/H has a stand-off voltage (VWM) of 12.8 V, meaning it remains non-conductive under normal operating conditions up to this DC or RMS voltage. This parameter prevents unwanted leakage or power loss while ensuring reliable clamping activation only when transients exceed the 14.3 V minimum breakdown threshold. For 12 V automotive systems, the TPSMC15AHE3_A/H's VWM provides sufficient margin against ripple and tolerance drift.
How does the TPSMC15AHE3_A/H differ from the TPSMC15AHM3_A/H?
The TPSMC15AHE3_A/H and TPSMC15AHM3_A/H share identical electrical specifications, package (SMC), and AEC-Q101 qualification. Their sole difference lies in material composition: HE3 uses standard RoHS-compliant molding compound, while HM3 adds halogen-free compliance per IEC 61249-2-21. The TPSMC15AHE3_A/H is selected when halogen-free content is not mandated, whereas HM3 is required for specific OEM green-material specifications.
What is the thermal rating and reflow compatibility of the TPSMC15AHE3_A/H?
The TPSMC15AHE3_A/H is rated for a maximum junction temperature (TJ) of +185 °C and meets MSL Level 1 per J-STD-020, allowing exposure to peak reflow temperatures up to 260 °C without preconditioning. Its SMC (DO-214AB) package with matte tin-plated leads ensures reliable solder joint formation per J-STD-002, making the TPSMC15AHE3_A/H fully compatible with standard lead-free SMT assembly lines.
