Product details
Overview
TPSMC11HE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, designed for clamping inductive switching surges and lightning-induced transients on power rails and signal lines. It features 1500 W peak pulse power (10/1000 μs), 9.9–12.1 V breakdown voltage (VBR), 8.92 V stand-off voltage (VWM), 16.2 V clamping voltage at 92.6 A (VC), and AEC-Q101 qualification for automotive electronics protection.
For engineers reviewing the TPSMC11HE3_A/I datasheet, TPSMC11HE3_A/I pinout, TPSMC11HE3_A/I application, or TPSMC11HE3_A/I equivalent, key selection criteria include unidirectional polarity, 185 °C junction temperature rating, MSL Level 1 moisture sensitivity, 200 A IFSM, and compliance with ANSI/IEEE C62.35 surge standards in high-reliability embedded systems.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver stable clamping under repetitive surge stress and elevated ambient temperatures up to 150 °C. Its low incremental surge resistance and fast response time ensure effective suppression of sub-microsecond transients without thermal runaway.
The device operates exclusively in unidirectional mode with cathode-band polarity marking, and is rated for non-repetitive 10/1000 μs waveform surges per Fig. 3 in the datasheet. Derating curves (Fig. 2) define safe operating limits above 25 °C ambient, supporting design in engine control units and industrial motor drives.
Key Specifications

Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Clamp |
|---|---|
|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between power input and ground to shunt surge energy away from LDOs and MCUs. Use Value: Withstands 200 A IFSM and clamps to ≤16.2 V, preventing latch-up in 16 V-tolerant automotive microcontrollers. |
Use Scenario: Shielding analog sensor outputs (e.g., pressure or temperature sensors) from ESD and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance TVS placed at connector interface to absorb ±8 kV contact ESD per IEC 61000-4-2 without distorting mV-level signals. Use Value: 16.2 V clamping ensures op-amp inputs remain within absolute maximum ratings while maintaining signal integrity. |
| Telecom DC Power Input Protection | Computer Peripheral USB VBUS Line Guard |
|
Use Scenario: Safeguarding PoE-powered equipment (e.g., IP cameras) from induced surges on 48 V DC input lines. IC Role / Device Role / Timing Role: Primary surge clamp on DC input before DC-DC converter, coordinated with upstream fuse and downstream MOV. Use Value: 1500 W PPPM and 185 °C rating allow sustained operation in sealed outdoor enclosures with minimal thermal margin loss. |
Use Scenario: Adding secondary overvoltage protection on USB 2.0 VBUS lines in docking stations exposed to hot-plug transients. IC Role / Device Role / Timing Role: Fast-response TVS placed after USB switch to limit VBUS spikes caused by capacitive charging currents. Use Value: Sub-1 ns response time and 8.92 V VWM prevent false overvoltage shutdowns while clamping to safe levels for USB PHY ICs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A-E3/5A (Vishay) | Same VWM (8.92 V) and VC (16.2 V), but lower PPPM = 400 W and smaller SMA package (DO-214AC) | Limited to lower-energy transients (IEC 61000-4-5 Level 2); unsuitable for load dump or high-current inductive switching | Select TPSMC11HE3_A/I when ≥1500 W surge handling and AEC-Q101 qualification are mandatory |
| 1.5SMC11A (ON Semiconductor) | Identical DO-214AB package and electrical specs (VBR, VWM, VC, PPPM), but not AEC-Q101 qualified and higher IR leakage at 150 °C | Acceptable for industrial/commercial use but excluded from automotive BOMs requiring AEC-Q101 traceability | Choose TPSMC11HE3_A/I for automotive Tier-1 programs requiring full AEC-Q101 documentation and 185 °C operation |
Compared with SMAJ11A-E3/5A and 1.5SMC11A, TPSMC11HE3_A/I delivers superior surge robustness and automotive-grade reliability-its 1500 W rating and 185 °C junction capability enable use in harsh environments where alternatives require derating or additional protection layers.

FAQ
What is the polarity configuration of the TPSMC11HE3_A/I?
The TPSMC11HE3_A/I is a unidirectional TVS diode, meaning it conducts only in reverse bias above its breakdown voltage. The cathode is marked by a color band on the DO-214AB package body, and it must be connected toward the protected line (e.g., 12 V rail), while the anode connects to ground. This configuration provides clamping action only during positive transients relative to ground.
Does the TPSMC11HE3_A/I meet AEC-Q101 requirements?
Yes, the TPSMC11HE3_A/I is fully AEC-Q101 qualified, as confirmed in the Vishay datasheet (Document Number: 88407, Revision: 22-Jul-16). It has passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD per the AEC-Q101 standard, making it suitable for automotive powertrain and chassis applications.
What is the maximum clamping voltage of the TPSMC11HE3_A/I at rated surge current?
The TPSMC11HE3_A/I clamps to a maximum of 16.2 V at its peak pulse current (IPPM) of 92.6 A, measured using the standardized 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and ensures protected downstream components remain within their absolute maximum voltage ratings.
Can the TPSMC11HE3_A/I be used in high-humidity or under-hood automotive environments?
Yes, the TPSMC11HE3_A/I is rated for operation from –65 °C to +185 °C and features a UL 94 V-0 compliant molding compound. Its MSL Level 1 rating and matte tin-plated terminals provide resistance to moisture absorption and whisker growth, enabling reliable performance in high-humidity engine bay and transmission control module locations.
How does the TPSMC11HE3_A/I compare to the TPSMC11A variant?
The TPSMC11HE3_A/I and TPSMC11A differ in tolerance and packaging: TPSMC11HE3_A/I has ±10 % VBR tolerance (9.9–12.1 V), while TPSMC11A offers ±5 % (10.5–11.6 V). Both share identical DO-214AB package, 1500 W rating, and AEC-Q101 qualification-but TPSMC11A provides tighter VBR control for precision clamping applications.
