Product details
Overview
TPSMC12AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, rated for 1500 W peak pulse power (10/1000 μs), 11.4–12.6 V breakdown voltage (VBR), and 16.7 V clamping voltage (VC) at 89.8 A peak surge current. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics against inductive switching transients.
For engineers reviewing the TPSMC12AHE3_A/H datasheet, TPSMC12AHE3_A/H pinout, TPSMC12AHE3_A/H application, or TPSMC12AHE3_A/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 185 °C junction temperature rating, 10.2 V stand-off voltage (VWM), and low 2 μA reverse leakage at VWM.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver stable clamping under high-temperature operation up to TJ = 185 °C. Its unidirectional architecture provides forward conduction only during positive overvoltage events on the cathode-banded terminal.
The device meets MSL Level 1 per J-STD-020 with 260 °C lead-free reflow capability and passes JESD201 Class 2 whisker testing. Clamping performance is characterized using standardized 10/1000 μs waveform per ANSI/IEEE C62.35.
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 |
|---|---|---|---|
| SMBJ12A | Lower PPPM (600 W), same VBR range (11.4–12.6 V), DO-214AA (SMB) package | Reduced surge margin; suitable only for lower-energy transients | Select when board space is constrained and peak surge energy is ≤600 W |
| TPSMC12AH | Same electrical specs but lacks HE3 suffix - not JESD201 Class 2 whisker tested or AEC-Q101 qualified | Not approved for automotive or long-life industrial deployments | Choose TPSMC12AHE3_A/H when whisker resistance and automotive qualification are mandatory |
Compared with SMBJ12A and TPSMC12AH, the TPSMC12AHE3_A/H delivers higher surge robustness (1500 W vs. 600 W), certified automotive reliability (AEC-Q101), and proven tin whisker resistance - making it the preferred choice for mission-critical 12 V rail protection where field failure risk must be minimized.

FAQ
What is the breakdown voltage range of the TPSMC12AHE3_A/H?
The TPSMC12AHE3_A/H has a specified breakdown voltage (VBR) range of 11.4 V to 12.6 V at 1 mA test current, measured per ANSI/IEEE C62.35. This ensures consistent turn-on behavior across production lots and temperature extremes, enabling predictable clamping in 12 V nominal systems.
Is the TPSMC12AHE3_A/H suitable for automotive applications?
Yes, the TPSMC12AHE3_A/H is AEC-Q101 qualified and rated for junction temperatures up to +185 °C, making it suitable for under-hood and powertrain applications. Its DO-214AB package, MSL Level 1 rating, and JESD201 Class 2 whisker resistance further validate its suitability for automotive-grade designs.
What does the "HE3_A/H" suffix indicate in TPSMC12AHE3_A/H?
The "HE3" suffix denotes RoHS-compliance, AEC-Q101 qualification, and JESD201 Class 2 whisker resistance. "A/H" specifies ±5 % VBR tolerance and packaging in 7-inch tape-and-reel (850 units). This full suffix confirms full automotive-grade process control and traceability for the TPSMC12AHE3_A/H.
How does the clamping voltage of TPSMC12AHE3_A/H compare to its breakdown voltage?
The TPSMC12AHE3_A/H clamps to 16.7 V at its rated peak pulse current of 89.8 A (10/1000 μs), which is approximately 1.4× its minimum breakdown voltage (11.4 V). This controlled voltage overshoot ensures protected circuits remain within safe operating area while absorbing high-energy transients.
Can TPSMC12AHE3_A/H replace TPSMC12AH in existing designs?
TPSMC12AHE3_A/H can replace TPSMC12AH electrically, but adds AEC-Q101 qualification, JESD201 Class 2 whisker resistance, and tighter process controls. No PCB changes are required due to identical DO-214AB package and pinout, though qualification documentation and sourcing traceability differ significantly for the TPSMC12AHE3_A/H.
