Product details
Overview
TPSMC11AHE3/57T 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 a 10.5 V minimum breakdown voltage (VBR), 9.40 V standoff voltage (VWM), 15.6 V clamping voltage at 96.2 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 and sensor line protection.
For engineers reviewing the TPSMC11AHE3/57T datasheet, TPSMC11AHE3/57T pinout, TPSMC11AHE3/57T application, or TPSMC11AHE3/57T equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, MSL Level 1 rating, 185 °C thermal capability, and low clamping voltage under surge conditions.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver stable clamping performance across wide temperature ranges. Its 10/1000 µs waveform response supports robust protection against inductive switching transients and ESD events in automotive and industrial environments.
The device is rated for 200 A non-repetitive forward surge current (IFSM) and exhibits low incremental surge resistance, enabling effective energy diversion without thermal runaway. Its cathode-band polarity marking and matte tin-plated terminals ensure reliable solderability per J-STD-002 and JESD 22-B102.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min) | 10.5 V - Ensures reliable triggering above normal operating voltage while avoiding false clamping during transients. |
| VWM | 9.40 V - Maximum continuous reverse working voltage; defines safe DC/AC operating margin before conduction. |
| VC @ IPPM | 15.6 V - Clamping voltage at 96.2 A peak pulse; limits downstream IC stress during 1500 W surge events. |
| PPPM | 1500 W - Peak pulse power handling with 10/1000 µs waveform; meets ISO 7637-2 and IEC 61000-4-5 requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A | Lower peak pulse power (400 W), same SMC package, identical VWM/VBR range but higher VC (18.2 V @ 22.5 A) | Not AEC-Q101 qualified; limited to commercial/industrial use where automotive reliability is not required | Select when cost sensitivity outweighs surge robustness and automotive qualification needs. |
| TPSMC11AHM3/57T | Halogen-free variant with identical electrical specs, same AEC-Q101 qualification, and identical thermal performance | Required for RoHS-compliant, halogen-free BOMs in EU automotive programs (e.g., VW TL 813) | Choose when halogen-free compliance is mandated by OEM or Tier 1 procurement specifications. |
Compared with SMAJ11A and TPSMC11AHM3/57T, the TPSMC11AHE3/57T delivers superior surge immunity (1500 W vs. 400 W), automotive-grade reliability, and optimized clamping - making it the preferred choice for safety-critical 12 V systems where long-term field stability is non-negotiable.

FAQ
What is the maximum clamping voltage of the TPSMC11AHE3/57T under surge conditions?
The TPSMC11AHE3/57T has a maximum clamping voltage (VC) of 15.6 V at its rated peak pulse current of 96.2 A (10/1000 µs waveform). This value is measured per ANSI/IEEE C62.35 and ensures downstream components see minimal overvoltage during standardized surge events. The clamping performance remains stable across its full operating temperature range up to +185 °C.
Is the TPSMC11AHE3/57T qualified for automotive applications?
Yes, the TPSMC11AHE3/57T is AEC-Q101 qualified and carries the HE3 suffix indicating RoHS-compliance and automotive-grade reliability. It undergoes rigorous stress testing including temperature cycling, highly accelerated life testing (HALT), and ESD verification per JEDEC standards - making it suitable for engine control units, body electronics, and ADAS power domains.
What package type does the TPSMC11AHE3/57T use, and what are its mounting requirements?
The TPSMC11AHE3/57T uses the SMC (DO-214AB) surface-mount package with matte tin-plated leads. Recommended mounting uses 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads at each terminal for optimal thermal dissipation and surge current handling. It meets MSL Level 1, so no pre-bake is required before reflow soldering.
How does the TPSMC11AHE3/57T differ from the TPSMC11AHM3/57T?
The TPSMC11AHE3/57T and TPSMC11AHM3/57T share identical electrical characteristics, AEC-Q101 qualification, and thermal ratings. The only difference is material composition: HM3 denotes halogen-free molding compound and terminations, while HE3 is RoHS-compliant but not halogen-free. Both meet JESD 201 Class 2 whisker resistance.
What is the reverse leakage current specification for the TPSMC11AHE3/57T at its standoff voltage?
At its 9.40 V standoff voltage (VWM), the TPSMC11AHE3/57T specifies a maximum reverse leakage current (IR) of 5.0 µA at 25 °C. At elevated temperature (TJ = 150 °C), leakage increases to 50 µA - a controlled, datasheet-guaranteed value that maintains signal integrity in precision analog and low-power sensor circuits.
