Product details
Overview
TPC10HM3/87A from Vishay General Semiconductor is a unidirectional 1500 W transient voltage suppressor (TVS) in SMPC (TO-277A) package, designed for high-reliability automotive and industrial electronics protection. It features a 10.0 V nominal breakdown voltage (VBR), 8.55 V stand-off voltage (VWM), clamping voltage of 103 V at 103 A peak pulse current, and operates up to +185 °C junction temperature.
For engineers reviewing the TPC10HM3/87A datasheet, TPC10HM3/87A pinout, TPC10HM3/87A application, or TPC10HM3/87A equivalent, key selection criteria include unidirectional surge handling capability, AEC-Q101 qualification, low-profile 1.1 mm height, MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on power rails and sensor signal lines.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for fast response (<1 ps) and low incremental surge resistance. Its unidirectional architecture provides robust protection against positive-going transients while maintaining low leakage (≤20 μA at VWM) and stable clamping performance across -65 °C to +185 °C operating range.
The device is rated for 1500 W peak pulse power (10/1000 μs waveform), supports 200 A non-repetitive forward surge current (8.3 ms half-sine), and delivers 3.5 V maximum forward voltage at 100 A - enabling effective overvoltage suppression in DC power distribution and I/O interface circuits without excessive conduction loss.
Key Specifications

|---|---|
| VBR (Nominal) | 10.0 V - ensures reliable triggering above normal operating voltage while avoiding false trips during ripple or tolerance drift |
| VWM | 8.55 V - defines maximum continuous reverse working voltage compatible with 9 V nominal supply rails |
| VC @ IPPM | 103 V - clamping voltage limits downstream IC stress during 103 A transient events |

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed microcontrollers and CAN transceivers from ISO 7637-2 pulse 1, 2a, and 5a transients in engine control units. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between power rail and chassis ground to divert surge energy away from sensitive logic. Use Value: Withstands 1500 W pulses and maintains clamping below 103 V, preventing latch-up or permanent damage to 3.3 V/5 V logic supplies. | Use Scenario: Safeguarding analog output lines (e.g., 4–20 mA current loops) in factory automation sensors exposed to relay coil flyback and ESD events. IC Role / Device Role / Timing Role: Fast-response TVS connected across signal and return paths to suppress sub-microsecond transients before they reach ADC inputs. Use Value: 103 V clamping voltage and ≤20 μA leakage preserve signal integrity and minimize offset errors in precision measurement circuits. |
| Telecom DC Power Input Protection | Consumer Device USB Power Path Protection |
Use Scenario: Guarding PoE-powered network switches and base stations against lightning-induced surges on 48 V DC input rails. IC Role / Device Role / Timing Role: Primary overvoltage clamp on secondary-side DC bus, coordinated with upstream fuses and MOVs. Use Value: 200 A IFSM rating and 185 °C TJ max support high-current surge handling without thermal runaway in sealed enclosures. | Use Scenario: Protecting USB-C PD power delivery circuits in portable monitors and docking stations from hot-plug transients and reverse polarity faults. IC Role / Device Role / Timing Role: Unidirectional TVS on VBUS line to clamp positive overshoot during plug insertion and cable discharge events. Use Value: Low 8.55 V VWM allows safe operation with 5–20 V PD profiles while 103 V clamping prevents damage to buck-boost controllers and port controllers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Lower PPPM (400 W), SMA package (higher thermal resistance), VC = 16.0 V at 32.4 A | Not AEC-Q101 qualified; limited to consumer/commercial grade designs | Choose for cost-sensitive non-automotive applications where surge energy is lower and space constraints less severe |
| TPC10AHM3_A | Same electrical specs and SMPC package; differs only in tape-and-reel packaging code (H vs. 87A) | No functional difference; identical performance and qualification status | Choose for standard 7" reel logistics; TPC10HM3/87A is functionally identical but supplied in alternate reel format |
Compared with SMAJ10A and TPC10AHM3_A, the TPC10HM3/87A offers superior surge robustness (1500 W vs. 400 W), automotive qualification, and lower clamping voltage - making it optimal for high-reliability 12 V systems where layout space permits SMPC mounting.

FAQ
What is the breakdown voltage specification for TPC10HM3/87A?
The TPC10HM3/87A has a nominal breakdown voltage (VBR) of 10.0 V, with minimum and maximum values of 9.5 V and 10.5 V respectively, measured at 1.0 mA test current. This ensures consistent triggering behavior across production lots and temperature ranges, supporting robust design margining in 9–12 V systems.
Is TPC10HM3/87A qualified for automotive applications?
Yes, TPC10HM3/87A is AEC-Q101 qualified and rated for operation up to +185 °C junction temperature. It meets automotive reliability requirements including temperature cycling, highly accelerated life testing (HALT), and electrostatic discharge (ESD) per JESD22-A114, making it suitable for under-hood and body-control module deployments.
What is the clamping voltage of TPC10HM3/87A at its rated peak pulse current?
The TPC10HM3/87A exhibits a maximum clamping voltage (VC) of 103 V when subjected to its rated peak pulse current (IPPM) of 103 A under the standard 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during surge events.
Does TPC10HM3/87A have a unidirectional or bidirectional configuration?
TPC10HM3/87A is strictly unidirectional. It conducts only during positive voltage transients relative to its anode terminal and blocks reverse voltage up to its 8.55 V stand-off rating. Bidirectional variants (e.g., TPC10CA) are separate part numbers and not interchangeable with TPC10HM3/87A.
What package type does TPC10HM3/87A use, and what are its key mechanical attributes?
TPC10HM3/87A uses the SMPC (TO-277A) package: a 3-terminal surface-mount outline measuring 3.70 mm × 4.80 mm with 1.1 mm typical height. It features matte tin-plated leads, complies with UL 94 V-0 flammability, and meets JESD201 Class 2 whisker resistance - all confirmed in Vishay Document Number 89056.
