Product details
Overview
TPSMC10AHE3_B/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-reliability overvoltage protection of sensitive electronics. It features 10 V nominal breakdown voltage (VBR), 8.55 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 µs), 14.5 V clamping voltage at 103 A peak surge current, and operates up to +185 °C junction temperature.
For engineers reviewing the TPSMC10AHE3_B/H datasheet, TPSMC10AHE3_B/H pinout, TPSMC10AHE3_B/H application, or TPSMC10AHE3_B/H equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal derating behavior, SMC package mechanical data, and real-world protection use cases in automotive power rails, industrial sensor interfaces, and DC-DC converter input stages.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology optimized for low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of ESD and inductive switching transients. Its unidirectional polarity and 10/1000 µs waveform-rated 1500 W capability target robust protection of downstream ICs and MOSFETs against repetitive and non-repetitive surges.
The device is rated for operation from –65 °C to +185 °C, with MSL Level 1 moisture sensitivity and JESD201 Class 2 whisker resistance. The HE3 suffix confirms RoHS compliance and AEC-Q101 qualification-critical for automotive ECUs and under-hood electronics requiring long-term reliability under thermal stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 9.5 V / 10.0 V / 10.5 V - defines precise voltage threshold at which clamping initiates under 1 mA test current |
| VWM | 8.55 V - maximum continuous reverse operating voltage before leakage exceeds 20 µA |
| VC @ IPPM | 14.5 V - clamped voltage seen by protected circuit during 103 A 10/1000 µs surge |
| PPPM | 1500 W - peak transient power dissipation capability without failure under standard waveform |
| TJ max. | +185 °C - enables placement near hot components (e.g., power MOSFETs, inductors) without derating loss |
| Polarity | Unidirectional - protects against positive-going transients only; requires correct cathode orientation |

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V supply lines in engine control units (ECUs) against load dump and alternator transients per ISO 7637-2. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and local regulator input to clamp surges before they reach LDOs or microcontrollers. Use Value: Withstands 1500 W pulses and operates up to +185 °C, ensuring uninterrupted function in under-hood environments where ambient temperatures exceed 125 °C. | Use Scenario: Safeguarding analog front-end inputs of pressure or temperature sensors connected to long cables in factory automation systems. IC Role / Device Role / Timing Role: TVS located at connector entry point to shunt induced lightning or EFT transients before signal conditioning circuitry. Use Value: 14.5 V clamping voltage ensures sensor ICs with 16 V absolute maximum ratings remain within safe operating limits during 1 kV/50 Ω EFT events. |
| DC-DC Converter Input Protection | Consumer USB Power Path Protection |
Use Scenario: Shielding buck converter inputs in PoE-powered devices from voltage spikes caused by cable hot-plug or inductor flyback. IC Role / Device Role / Timing Role: Placed upstream of input filter capacitor to absorb energy before it stresses MOSFETs or controller ICs. Use Value: Fast sub-nanosecond response and low dynamic impedance limit voltage overshoot to ≤14.5 V, preventing gate oxide stress on 20 V-rated input FETs. | Use Scenario: Overvoltage protection on 5 V USB VBUS lines in portable docking stations exposed to accidental 12 V adapter misconnection. IC Role / Device Role / Timing Role: Unidirectional TVS between VBUS and ground to clamp misapplied voltage before USB controller or charging IC. Use Value: 8.55 V stand-off allows normal 5 V operation with <20 µA leakage, while 14.5 V clamping prevents damage to 6 V-rated USB PHYs. |
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 | Lower peak power rating (400 W), same SMC package, identical VBR range but higher VC (16.7 V) | Not suitable for automotive load dump; limited to lower-energy ESD/EFT scenarios | Select SMAJ10A only for cost-sensitive consumer applications where 1500 W surge immunity is not required. |
| TPSMC10AHM3_B/H | Identical electrical specs; HM3 suffix adds halogen-free construction and same AEC-Q101 qualification | No functional difference; used when halogen-free compliance is mandated by OEM or regional regulations | Choose TPSMC10AHM3_B/H if RoHS + halogen-free material declaration is contractually required. |
Compared with SMAJ10A and TPSMC10AHM3_B/H, the TPSMC10AHE3_B/H provides the highest surge robustness in its footprint, with 1500 W capability unmatched by SMAJ-series, while offering identical performance to HM3 except for halogen content-making HE3 optimal for general automotive and industrial use where halogen-free is not mandated.

FAQ
What is the clamping voltage of the TPSMC10AHE3_B/H at its rated peak pulse current?
The TPSMC10AHE3_B/H has a maximum clamping voltage (VC) of 14.5 V when subjected to its rated peak pulse current (IPPM) of 103 A under the standard 10/1000 µs waveform. This value is measured per Figure 1 in the Vishay datasheet 88407 and ensures protected circuits remain below critical overvoltage thresholds. The TPSMC10AHE3_B/H achieves this with low dynamic impedance and fast response, making it suitable for safeguarding 12 V–16 V rated ICs.
Is the TPSMC10AHE3_B/H qualified for automotive applications?
Yes, the TPSMC10AHE3_B/H is AEC-Q101 qualified, as confirmed by the HE3 suffix in its ordering code and explicitly stated in the Vishay datasheet revision 19-Jan-2024. It meets stress tests including temperature cycling, high-temperature reverse bias, and mechanical shock per JEDEC standards. The TPSMC10AHE3_B/H is intended for under-hood and chassis-mounted modules where junction temperatures may reach +185 °C.
What does the "HE3" suffix mean in TPSMC10AHE3_B/H?
The "HE3" suffix in TPSMC10AHE3_B/H indicates RoHS-compliant construction and AEC-Q101 qualification. It also denotes compliance with JESD201 Class 2 whisker resistance and MSL Level 1 moisture sensitivity. The "B/H" denotes packaging: 7-inch tape-and-reel with 850 units per reel. The TPSMC10AHE3_B/H is not halogen-free; for that specification, the HM3 variant must be selected.
Can the TPSMC10AHE3_B/H replace SMAJ10A in an existing design?
The TPSMC10AHE3_B/H is not a direct drop-in replacement for SMAJ10A due to differences in surge capability and clamping behavior: SMAJ10A offers only 400 W peak power and clamps at 16.7 V versus 1500 W and 14.5 V for the TPSMC10AHE3_B/H. While both use SMC packages, layout changes may be needed to accommodate higher thermal dissipation. The TPSMC10AHE3_B/H should be validated for thermal and electrical margins before substitution.
What is the maximum reverse leakage current of the TPSMC10AHE3_B/H at 8.55 V and 150 °C?
At VWM = 8.55 V and TJ = 150 °C, the TPSMC10AHE3_B/H exhibits a maximum reverse leakage current (ID) of 200 µA, as specified in Table 1 of the Vishay datasheet 88407. This elevated leakage-compared to 20 µA at 25 °C-is expected due to thermal generation and remains within safe limits for most protection applications. The TPSMC10AHE3_B/H maintains functionality despite this increase, supported by its 185 °C rating.
