Product details
Overview
TPSMC10AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, designed for high-reliability overvoltage protection of sensitive electronics. It features 1500 W peak pulse power (10/1000 μs), 9.5–10.5 V breakdown voltage at 1 mA, 8.55 V stand-off voltage, and clamps to ≤14.5 V at 103 A surge current - deployed on power rails and signal lines in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the TPSMC10AHE3_A/I datasheet, TPSMC10AHE3_A/I pinout, TPSMC10AHE3_A/I application, or TPSMC10AHE3_A/I equivalent, key selection criteria include its AEC-Q101 qualification, TJ = 185 °C operation, MSL Level 1 rating, uni-directional polarity, and 103 A peak surge current capability under standardized 10/1000 μs waveform conditions.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for junction stability under repetitive transients and high ambient temperatures. Its clamping behavior is characterized by low incremental surge resistance and fast response time, enabling effective suppression of inductive switching spikes and lightning-induced surges on DC power inputs and analog signal paths.
The device operates within -65 °C to +185 °C junction temperature range and meets JESD201 Class 2 whisker resistance requirements. Its DO-214AB package supports soldering per J-STD-002 and JESD22-B102, with matte tin-plated terminals and UL 94 V-0 molding compound.
Key Specifications

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 DO-214AC (SMA) package, VBR = 11.1–12.3 V, VC = 16.7 V @ 24.7 A | Not suitable for 103 A surge scenarios; limited to lower-energy transients (e.g., board-level ESD only) | Select SMAJ10A only if system-level surge testing confirms <400 W requirement and space constraints favor smaller SMA footprint. |
| SMCJ10A | Same DO-214AB (SMC) package, identical VBR/VWM/VC, but rated for 1500 W with tighter VBR tolerance (±5 % vs. ±5.3 %) and higher IFSM (250 A vs. 200 A) | Compatible in layout and function; preferred where higher single-pulse surge margin or extended lifetime under repeated stress is required | SMCJ10A offers direct form-fit-function replacement with enhanced surge endurance - verify thermal pad layout matches TPSMC10AHE3_A/I's 8 mm × 8 mm requirement. |
Compared with SMAJ10A and SMCJ10A, the TPSMC10AHE3_A/I delivers identical clamping performance and package compatibility as SMCJ10A but with AEC-Q101 qualification and JESD201 Class 2 whisker resistance - making it the preferred choice for automotive and high-reliability industrial deployments where process traceability and long-term intermetallic stability are mandatory.

FAQ
What is the exact breakdown voltage range for TPSMC10AHE3_A/I?
The TPSMC10AHE3_A/I has a guaranteed breakdown voltage (VBR) range of 9.5 V to 10.5 V at 1 mA test current, as specified in the Vishay datasheet revision 22-Jul-16. This tight tolerance ensures predictable clamping onset across production lots and supports precise system-level surge margin analysis. The value is measured after applying square-wave IT for 300 μs and conforms to ANSI/IEEE C62.35 definitions. TPSMC10AHE3_A/I maintains this specification across its full operating temperature range.
Is TPSMC10AHE3_A/I suitable for automotive applications?
Yes, TPSMC10AHE3_A/I is AEC-Q101 qualified and rated for junction temperatures up to +185 °C, making it suitable for under-hood and powertrain-related automotive applications. It meets JESD201 Class 2 whisker resistance, MSL Level 1 reflow compatibility, and has been validated for temperature cycling, high-temperature reverse bias, and accelerated life testing per AEC-Q101 requirements. TPSMC10AHE3_A/I is commonly used in engine control units, body electronics, and ADAS power domains.
What is the clamping voltage of TPSMC10AHE3_A/I at its rated surge current?
The TPSMC10AHE3_A/I clamps to a maximum of 14.5 V when subjected to its peak pulse current (IPPM) of 103 A under the standard 10/1000 μs waveform. This clamping voltage is measured at the device terminals with specified mounting conditions (0.31" × 0.31" copper pads). The low clamping ratio (VC/VBR ≈ 1.45) reflects efficient energy diversion and ensures downstream components remain within safe operating voltage limits during surge events. TPSMC10AHE3_A/I achieves this performance with minimal incremental surge resistance.
Does TPSMC10AHE3_A/I have bidirectional polarity?
No, TPSMC10AHE3_A/I is a unidirectional TVS diode only, as explicitly stated in the Vishay datasheet. It conducts surge current from cathode to anode when the cathode voltage exceeds the breakdown threshold relative to the anode. It does not provide symmetrical clamping for AC or bipolar signals. For bidirectional protection, two TPSMC10AHE3_A/I devices would need back-to-back configuration, or a dedicated bidirectional part such as TPSMC10CA must be selected. Polarity is marked by a cathode band on the DO-214AB package.
What packaging and reel options are available for TPSMC10AHE3_A/I?
TPSMC10AHE3_A/I is supplied in 13-inch diameter plastic tape and reel format with a base quantity of 3500 pieces per reel, as indicated by the "I" package code in the ordering designation. The device uses matte tin-plated leads compliant with J-STD-002 and JESD22-B102 solderability standards. Tape dimensions and sprocket hole pitch conform to EIA-481-D specifications. TPSMC10AHE3_A/I reels are compatible with standard high-speed pick-and-place equipment and support automated SMT assembly without pre-baking due to MSL Level 1 rating.
