Product details
Overview
TPSMC11AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping fast voltage transients on power and signal lines. It features a 11.0 V nominal breakdown voltage (VBR), 9.40 V stand-off voltage (VWM), 15.6 V maximum clamping voltage (VC) 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 protection.
For engineers reviewing the TPSMC11AHE3_A/H datasheet, TPSMC11AHE3_A/H pinout, TPSMC11AHE3_A/H application, or TPSMC11AHE3_A/H equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal derating behavior, SMC package mechanical data, and real-world use cases in automotive ECUs and industrial sensor interfaces.
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 handling on DC rails, and its 10/1000 μs waveform rating reflects standardized IEC 61000-4-5 surge immunity compliance testing conditions.
The device achieves low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of ESD and load-switching transients before downstream ICs are damaged. Its TJ = –65 °C to +185 °C operating range and MSL Level 1 rating support reflow soldering and under-hood automotive deployment without derating penalties.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 10.5 / 11.0 / 11.6 V - ensures reliable triggering above system nominal voltage while avoiding false trips during ripple or tolerance drift |
| VWM | 9.40 V - maximum continuous reverse voltage before leakage exceeds 5.0 μA, suitable for 9 V nominal supply rails |
| VC @ IPPM | 15.6 V - clamps transients to safe levels for 3.3 V or 5 V logic interfaces when subjected to 96.2 A surge |
| PPPM | 1500 W - sustains single-event surges per IEC 61000-4-5 Level 4 (4 kV line-to-ground) without degradation |
| TJ max. | +185 °C - supports placement near heat sources (e.g., power MOSFETs, motor drivers) in automotive modules |

Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Clamping |
|---|---|
|
Use Scenario: Protecting 12 V battery-fed microcontroller power inputs in engine control units against load dump and jump-start transients. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between VIN and GND, clamping surges within nanoseconds before regulator input stage fails. Use Value: Withstands 200 A IFSM and maintains VC ≤ 15.6 V at 96.2 A, preserving LDO integrity and preventing brownout resets during ISO 7637-2 Pulse 5a events. |
Use Scenario: Shielding analog output lines (e.g., 4–20 mA current loop) of pressure sensors in factory automation systems from EMI-induced spikes. IC Role / Device Role / Timing Role: TVS placed across signal and return lines to shunt transient energy before it reaches precision DAC or op-amp output stage. Use Value: 10.5–11.6 V VBR window avoids interference with normal 24 V loop operation while clamping ESD to <15.6 V, maintaining signal fidelity and calibration stability. |
| Telecom DC Power Input Protection | Consumer USB-C Power Delivery Interface |
|
Use Scenario: Safeguarding primary-side DC/DC converter inputs in PoE-powered network switches exposed to lightning-induced surges on Ethernet cables. IC Role / Device Role / Timing Role: Front-end unidirectional TVS absorbing common-mode transients coupled onto 48 V DC bus before isolation barrier. Use Value: 1500 W PPPM and 185 °C TJ rating allow sustained operation in sealed enclosures with ambient temperatures up to +85 °C without derating. |
Use Scenario: Adding secondary-level surge protection on VBUS lines of USB-C receptacles in portable monitors and docking stations. IC Role / Device Role / Timing Role: TVS placed after Type-C CC logic but before buck converter, limiting VBUS overvoltage during hot-plug or adapter fault conditions. Use Value: 9.40 V VWM permits compatibility with USB PD 3.0 9 V PPS profiles, while 15.6 V VC prevents damage to 12 V-rated power switches and controllers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A | Lower PPPM (400 W), same VBR range, SMA package (smaller footprint, lower thermal mass) | Limited to lower-energy transients (IEC 61000-4-2 ESD only); not rated for ISO 7637-2 load dump | Select when space-constrained and surge threat level is limited to board-level ESD, not system-level surges. |
| TPSMC11AHM3_A/H | Identical electrical specs; HM3 suffix denotes halogen-free construction (vs. HE3's RoHS-only compliance) | No functional difference; HM3 required where halogen-free mandate applies (e.g., EU public transport, aerospace) | Choose HM3 if halogen-free material declaration is contractually required; otherwise HE3 offers identical performance. |
Compared with TPSMC11AHE3_A/H, SMAJ11A provides reduced surge handling capacity and thermal robustness, while TPSMC11AHM3_A/H delivers identical protection performance with stricter material compliance - making HE3 the optimal balance of automotive qualification, surge margin, and procurement flexibility.

FAQ
What is the exact breakdown voltage range for TPSMC11AHE3_A/H?
The TPSMC11AHE3_A/H has a guaranteed breakdown voltage (VBR) range of 10.5 V (minimum) to 11.6 V (maximum) at 1 mA test current, with a nominal value of 11.0 V. This range is measured per ANSI/IEEE C62.35 standards and remains stable across temperature due to its +0.067 %/°C temperature coefficient - critical for predictable clamping in automotive under-hood applications where ambient can exceed 125 °C.
Is TPSMC11AHE3_A/H qualified for automotive use?
Yes, TPSMC11AHE3_A/H is AEC-Q101 qualified, as confirmed by Vishay's official documentation (Document Number 88407, Revision 19-Jan-2024). The HE3 suffix explicitly denotes RoHS-compliant and AEC-Q101-qualified versions. Qualification includes stress tests such as high-temperature reverse bias (HTRB), temperature cycling, and ESD - validating suitability for engine control units, body control modules, and ADAS sensor assemblies.
What does the "HE3" suffix mean in TPSMC11AHE3_A/H?
The "HE3" suffix in TPSMC11AHE3_A/H indicates RoHS-compliant construction with matte tin-plated leads, JESD201 Class 2 whisker resistance, and full AEC-Q101 qualification. The "_A/H" denotes revision code A and packaging in 7″ tape-and-reel (H = 850 pcs/reel). This distinguishes it from HM3 (halogen-free + RoHS + AEC-Q101) and non-automotive base part numbers lacking qualification evidence.
How does TPSMC11AHE3_A/H compare to SMAJ11A in surge handling?
TPSMC11AHE3_A/H delivers 1500 W peak pulse power (10/1000 μs), more than 3.7× higher than SMAJ11A's 400 W rating. Its larger SMC package provides superior thermal dissipation and higher IFSM (200 A vs. 40 A), enabling reliable protection against ISO 7637-2 load dump events - whereas SMAJ11A is limited to board-level ESD per IEC 61000-4-2 and cannot sustain automotive system-level surges.
What is the maximum clamping voltage of TPSMC11AHE3_A/H at rated surge current?
The maximum clamping voltage (VC) of TPSMC11AHE3_A/H is 15.6 V at 96.2 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value is measured per JEDEC standards and guarantees that downstream components - such as 16 V-rated LDOs or 5 V logic - remain within safe operating limits during worst-case transient events, provided the PCB layout minimizes trace inductance.
