Product details
Overview
TPSMC15AHE3_A/I 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), 21.2 V maximum clamping voltage at 70.8 A peak pulse current, 1500 W peak pulse power (10/1000 µs), and operates up to +185 °C junction temperature - ideal for automotive power rail protection.
For engineers reviewing the TPSMC15AHE3_A/I datasheet, TPSMC15AHE3_A/I pinout, TPSMC15AHE3_A/I application, or TPSMC15AHE3_A/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, MSL Level 1 rating, 1.0 µA max reverse leakage at VWM, and compatibility with high-reliability automotive and industrial PCB layouts requiring robust ESD/surge immunity without derating at elevated temperatures.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver stable clamping performance across -65 °C to +185 °C operating range. Its low incremental surge resistance and fast response time ensure effective suppression of inductive switching spikes and lightning-induced surges on DC power rails and sensor interfaces.
The device is rated for 200 A non-repetitive forward surge current (8.3 ms half-sine) and exhibits a typical VBR temperature coefficient of +0.076 %/°C, enabling predictable voltage threshold behavior under thermal stress in engine control units and battery management systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 14.3 / 15.0 / 15.8 V - ensures reliable conduction onset above normal 12 V system rail during transients |
| VWM | 12.8 V - blocks leakage below system nominal voltage while allowing safe margin before clamping |
| VC @ IPPM | 21.2 V - limits downstream IC voltage stress during 70.8 A surge, protecting 24 V-rated components |
| PPPM | 1500 W (10/1000 µs) - handles high-energy load dump and ISO 7637-2 Pulse 5a events |
| TJ max | +185 °C - supports under-hood automotive placement without thermal derating penalties |
| Leakage @ VWM | 1.0 µA - minimizes standby power loss in always-on vehicle modules |
| AEC-Q101 qualified | Yes - validated for automotive electronic systems per stress test requirements |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, matte tin-plated leads, RoHS-compliant and halogen-free (HE3 suffix), MSL Level 1, 260 °C reflow compatible.

Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power (10/1000 µs) | Withstands severe ISO 7637-2 load dump and coupled surge events in automotive ECUs |
| Junction temperature rating up to +185 °C | Enables direct mounting near heat sources (e.g., power converters) without thermal throttling |
| Unidirectional polarity only | Simplifies layout for DC-biased rails where reverse conduction is not required |
| Low clamping ratio (VC/VBR ≈ 1.41) | Minimizes overvoltage overshoot during fast transients, improving system-level robustness |
| Meets JESD201 Class 2 whisker resistance | Ensures long-term solder joint integrity in vibration-prone automotive environments |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V supply inputs of engine control units (ECUs) against load dump and alternator transients. IC Role / Device Role / Timing Role: Transient voltage suppressor placed between battery rail and input filter capacitor.

IC Role / Device Role / Timing Role: Unidirectional TVS connected between signal line and local ground plane. Use Value: Limits induced ESD and switching noise to <22 V, preserving ADC reference integrity and avoiding false trip conditions in safety-critical loops. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A | Lower PPPM (400 W), same VBR range, SMA package (smaller footprint, lower thermal mass) | Not AEC-Q101 qualified; limited to commercial-grade consumer/industrial use | Select when space-constrained layouts prioritize size over automotive reliability and surge energy handling |
| TPSMC15AHM3_A/I | Identical electrical specs; HM3 suffix denotes halogen-free construction (vs. HE3's RoHS-only) | No functional difference; used where halogen-free compliance is mandated by OEM procurement policy | Choose HM3 version if material compliance requirements exceed standard RoHS, e.g., Tier 1 automotive BOMs |
Compared with TPSMC15AHE3_A/I, SMAJ15A offers reduced surge capability and no automotive qualification, while TPSMC15AHM3_A/I provides identical protection performance with stricter material compliance - making the HE3 variant optimal for cost-sensitive AEC-Q101 applications where halogen-free status is not contractually required.

FAQ
What is the clamping voltage of TPSMC15AHE3_A/I at its rated peak pulse current?
The TPSMC15AHE3_A/I has a maximum clamping voltage (VC) of 21.2 V when subjected to its peak pulse current (IPPM) of 70.8 A under the standardized 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures predictable overvoltage limiting for downstream 24 V-rated ICs. The clamping performance is guaranteed across the full -65 °C to +185 °C operating junction temperature range.
Is TPSMC15AHE3_A/I qualified for automotive applications?
Yes, TPSMC15AHE3_A/I is AEC-Q101 qualified, as confirmed by Vishay's official documentation and ordering code suffix "HE3", which denotes RoHS-compliant and AEC-Q101 qualified variants. It meets all stress tests defined in AEC-Q101, including high-temperature operating life, temperature cycling, and surge robustness - making it suitable for engine control, body electronics, and ADAS power domains.
What does the "HE3" suffix mean in TPSMC15AHE3_A/I?
The "HE3" suffix in TPSMC15AHE3_A/I indicates that the device is RoHS-compliant and AEC-Q101 qualified, with matte tin-plated leads meeting J-STD-002 and JESD 22-B102 solderability standards. The "_A/I" denotes revision A and packaging in 13-inch tape-and-reel (3500 units). HE3 parts are distinct from HM3 variants, which add halogen-free compliance.
Can TPSMC15AHE3_A/I be used in bidirectional configurations?
No, TPSMC15AHE3_A/I is unidirectional only, as explicitly stated in Vishay's datasheet. It conducts in reverse bias during overvoltage events but blocks forward current beyond ~3.5 V. For AC or bipolar signal line protection, a dedicated bidirectional TVS (e.g., TPSMC15CA) or back-to-back configuration would be required - TPSMC15AHE3_A/I must not be applied where reverse polarity transients occur.
What is the maximum reverse leakage current of TPSMC15AHE3_A/I at its stand-off voltage?
At 25 °C, TPSMC15AHE3_A/I exhibits a maximum reverse leakage current (IR) of 1.0 µA when biased at its stand-off voltage (VWM) of 12.8 V. At elevated temperature (TJ = 150 °C), leakage increases to 10 µA - still well within low-power design budgets for always-on automotive modules. This parameter is verified per test condition in the Electrical Characteristics table of Document Number 88407.
