Product details
Overview
TPSMC10HE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping inductive switching transients and lightning-induced surges on power and signal lines. It features 10 V breakdown voltage (VBR = 9.5–10.5 V at 1 mA), 8.55 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 µs), 14.5 V clamping voltage at 103 A, and operates up to +185 °C junction temperature - deployed in automotive power rails and industrial sensor interfaces.
For engineers reviewing the TPSMC10HE3_A/I datasheet, TPSMC10HE3_A/I pinout, TPSMC10HE3_A/I application, or TPSMC10HE3_A/I equivalent, this page delivers verified electrical parameters, thermal derating behavior, AEC-Q101 qualification status, SMC package mechanical data, and validated alternative parts for surge protection design-in.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with optimized junction passivation for stable clamping under high-temperature stress. Its unidirectional polarity enables forward-biased surge conduction during overvoltage events on positive-rail systems, while maintaining low leakage (<20 µA at VWM) and fast response time (<1 ns).
The device meets MSL Level 1 per J-STD-020, supports 260 °C lead-free reflow, and is qualified to AEC-Q101 - confirming suitability for automotive under-hood and industrial control environments where TJ = 185 °C operation and 200 A IFSM surge robustness are required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 9.5 / 10.0 / 10.5 V at 1 mA - defines precise voltage threshold for avalanche conduction onset |
| VWM | 8.55 V - maximum continuous reverse operating voltage before leakage exceeds 20 µA |
| VC @ IPPM | 14.5 V at 103 A - clamped voltage limiting downstream IC/MOSFET stress during 10/1000 µs surge |
| PPPM | 1500 W - peak transient energy absorption capability under standardized waveform |
| TJ max. | +185 °C - enables placement near hot components (e.g., power converters, motor drivers) |
| IFSM | 200 A - withstands 8.3 ms half-sine surge without failure, critical for relay/coil suppression |
| Leakage @ VWM, 150 °C | 200 µA - ensures minimal standby current impact in battery-powered sensor nodes |

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 PPPM (400 W), same VBR range, SMA package (smaller footprint, lower thermal mass) | Limited to lower-energy transients (e.g., IEC 61000-4-5 Level 2); unsuitable for ISO 7637-2 Pulse 5a | Select when space-constrained and surge energy <50 mJ; verify thermal dissipation on 1 oz copper |
| TPSMC10AHM3_A/I | Identical electrical specs; halogen-free molding compound and JESD 201 Class 2 whisker resistance | Required for RoHS+halogen-free compliance in EU medical and consumer devices | Choose for strict material compliance mandates; no layout or performance change needed |
Compared with SMAJ10A and TPSMC10AHM3_A/I, the TPSMC10HE3_A/I offers higher surge robustness (1500 W vs. 400 W) and AEC-Q101 qualification out-of-box, while sharing the same SMC footprint - making it optimal for automotive and industrial designs requiring proven high-energy clamping and extended temperature operation.

FAQ
What is the clamping voltage of the TPSMC10HE3_A/I at its rated peak pulse current?
The TPSMC10HE3_A/I exhibits 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 circuitry remains within safe voltage margins during surge events. The TPSMC10HE3_A/I maintains this clamping performance across its full operating temperature range.
Is the TPSMC10HE3_A/I qualified for automotive use?
Yes, the TPSMC10HE3_A/I is AEC-Q101 qualified, as confirmed in the Vishay datasheet 88407 under "FEATURES" and "ORDERING INFORMATION". Its HE3 suffix denotes RoHS-compliant and AEC-Q101 qualified construction, enabling use in automotive powertrain, body control, and ADAS modules where high-temperature reliability and surge immunity are required. The TPSMC10HE3_A/I undergoes stress testing including HTGB, HTRB, and temperature cycling per AEC-Q101.
What is the difference between TPSMC10HE3_A/I and TPSMC10AHM3_A/I?
The TPSMC10HE3_A/I and TPSMC10AHM3_A/I share identical electrical specifications, package (SMC), and AEC-Q101 qualification. The distinction lies in materials: TPSMC10AHM3_A/I uses halogen-free molding compound and meets JESD 201 Class 2 whisker resistance, whereas TPSMC10HE3_A/I is RoHS-compliant but not halogen-free. Both are drop-in replacements electrically and mechanically; the TPSMC10HE3_A/I is selected when halogen-free compliance is not mandated.
What is the maximum operating junction temperature for the TPSMC10HE3_A/I?
The TPSMC10HE3_A/I has a maximum operating junction temperature (TJ) of +185 °C, as specified in the "PRIMARY CHARACTERISTICS" table and "MAXIMUM RATINGS" section of Vishay document 88407. This rating enables reliable operation in high-ambient environments such as engine compartments or industrial motor drives, and supports full-rated power dissipation up to 125 °C ambient with appropriate PCB copper area.
Does the TPSMC10HE3_A/I have unidirectional or bidirectional polarity?
The TPSMC10HE3_A/I is a unidirectional TVS diode, as explicitly stated in the "FEATURES" section of the Vishay datasheet: "Available in unidirectional polarity only." Its cathode is marked by a color band, and it conducts surge current only when the cathode is at a higher potential than the anode - making it suitable for protecting positive-rail systems like 12 V or 24 V supplies. The TPSMC10HE3_A/I does not provide symmetrical clamping for AC or dual-rail applications.
