Product details
Overview
TPSMC11HE3_A/H 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), 9.9–12.1 V breakdown voltage (VBR), 8.92 V stand-off voltage (VWM), and 16.2 V clamping voltage (VC) at 92.6 A peak surge current - used to safeguard MOSFETs, ICs, and sensor signal lines in automotive and industrial power rails.
For engineers reviewing the TPSMC11HE3_A/H datasheet, TPSMC11HE3_A/H pinout, TPSMC11HE3_A/H application, or TPSMC11HE3_A/H equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C junction temperature rating, unidirectional polarity, low clamping ratio (VC/VBR ≈ 1.47), and MSL Level 1 moisture sensitivity - critical for under-hood automotive modules and high-temperature industrial controllers.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology with optimized junction passivation for stable performance under thermal stress. Its unidirectional configuration provides forward conduction path during reverse overvoltage events, enabling robust clamping on DC-biased lines such as 12 V automotive power supplies and industrial 24 V control inputs.
The device operates across -65 °C to +185 °C junction temperature range and meets JESD201 Class 2 whisker resistance requirements. Its 1500 W peak pulse power rating is specified per ANSI/IEEE C62.35 with 10/1000 μs waveform, and clamping behavior is validated under derated conditions above 25 °C ambient per Fig. 2 of the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 9.9 V / 12.1 V - defines minimum voltage at which device enters avalanche breakdown; ensures reliable triggering above normal operating voltage (VWM = 8.92 V). |
| VC @ IPPM | 16.2 V - maximum clamped voltage during 92.6 A surge; limits downstream component stress to safe levels in 12 V systems. |
| PPPM | 1500 W - peak pulse power handling capability with 10/1000 μs waveform; supports high-energy transients from inductive load switching. |
| IFSM | 200 A - non-repetitive forward surge current (8.3 ms half-sine); withstands repeated load-dump events in automotive environments. |
| TJ max. | +185 °C - maximum junction temperature; enables operation in under-hood locations without thermal derating penalties. |
| MSL Level | Level 1 per J-STD-020 - allows unlimited floor life and reflow up to 260 °C peak; eliminates baking requirements for SMT assembly. |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, cathode indicated by color band. Molded compound meets UL 94 V-0 flammability rating; matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point during clamping | Connected to protected line's lower-potential side (e.g., ground or return path) in unidirectional configuration. |
| Cathode | Avalanche conduction terminal | Connected to protected line's higher-potential side (e.g., 12 V rail); color band identifies this terminal for correct PCB orientation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - required for engine control units and ADAS power domains. |
| 185 °C junction rating | Enables direct placement near heat sources (e.g., power converters) without external thermal management or derating. |
| 1500 W peak pulse power | Handles ISO 7637-2 Pulse 5a (load dump) and IEC 61000-4-5 surge events without degradation in 12 V systems. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (<1 ns rise time), improving protection margin for fast-switching MOSFET gates. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ11A | Same VWM (8.92 V) and VC (18.2 V), but lower PPPM (600 W) and smaller SMB package (DO-214AA). | Lower power handling limits use to sub-100 A surge environments; not suitable for automotive load dump. | Select when board space is constrained and surge energy is limited to IEC 61000-4-2/4-4 only. |
| TPSMC11AHE3_A/H | Narrower VBR tolerance (±5 % vs. ±10 %), tighter 10.5–11.6 V range, same package and clamping (15.6 V). | Better voltage consistency across production lots; preferred for precision clamping where VBR distribution affects system margin. | Choose for high-volume automotive programs requiring tighter parametric control and AEC-Q101 traceability. |
Compared with SMBJ11A and TPSMC11AHE3_A/H, the TPSMC11HE3_A/H offers optimal balance of 1500 W surge capacity, AEC-Q101 compliance, and DO-214AB thermal mass - making it the default choice for under-hood 12 V rail protection where both energy handling and long-term reliability are mandatory.

FAQ
What is the breakdown voltage range of the TPSMC11HE3_A/H?
The TPSMC11HE3_A/H has a guaranteed breakdown voltage (VBR) range of 9.9 V to 12.1 V at 1 mA test current, measured per ANSI/IEEE C62.35. This ±10 % tolerance ensures consistent triggering across production lots while accommodating thermal drift up to 185 °C junction temperature - a key specification for TPSMC11HE3_A/H in automotive power rail protection.
Is the TPSMC11HE3_A/H qualified for automotive applications?
Yes, the TPSMC11HE3_A/H is AEC-Q101 qualified and rated for operation from -65 °C to +185 °C junction temperature. It passes rigorous automotive stress tests including temperature cycling, highly accelerated life testing (HALT), and ESD per JESD22-A114 - confirming suitability for engine control modules, body electronics, and ADAS subsystems where TPSMC11HE3_A/H is deployed as primary overvoltage protection.
What is the clamping voltage of the TPSMC11HE3_A/H at its rated surge current?
The TPSMC11HE3_A/H clamps to a maximum of 16.2 V at its peak pulse current (IPPM) of 92.6 A, measured with a 10/1000 μs waveform. This clamping voltage defines the upper voltage limit imposed on protected circuitry during surge events - a critical parameter ensuring downstream components like TPSMC11HE3_A/H-powered microcontrollers remain within their absolute maximum ratings.
Does the TPSMC11HE3_A/H have unidirectional or bidirectional polarity?
The TPSMC11HE3_A/H is unidirectional only, with cathode identified by a color band. Its electrical behavior mirrors a Zener diode in reverse bias and a forward-biased PN junction in forward conduction - making it appropriate for DC-biased lines such as 12 V automotive supplies. Bidirectional variants (e.g., TPSMC11CA) are separate part numbers and not interchangeable with TPSMC11HE3_A/H.
What packaging and moisture sensitivity level does the TPSMC11HE3_A/H use?
The TPSMC11HE3_A/H is supplied in DO-214AB (SMC) package on 7" plastic tape and reel (H code), with MSL Level 1 per J-STD-020 - allowing unlimited floor life and reflow at peak temperatures up to 260 °C. This eliminates pre-baking requirements and simplifies SMT manufacturing for TPSMC11HE3_A/H in high-volume automotive and industrial production lines.
