Product details
Overview
TPC16AHM3/87A 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 surge protection. It features a 16.0 V nominal breakdown voltage (VBR), 13.6 V stand-off voltage (VWM), clamping voltage of 22.5 V at 66.7 A peak pulse current, and operates up to +185 °C junction temperature.
For engineers reviewing the TPC16AHM3/87A datasheet, TPC16AHM3/87A pinout, TPC16AHM3/87A application, or TPC16AHM3/87A equivalent, key selection criteria include unidirectional clamping performance under 10/1000 µs transients, AEC-Q101 qualification, low-profile 1.1 mm height, and compatibility with automated SMT placement on automotive ECUs and sensor interfaces.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology optimized for low incremental surge resistance and fast response time (<1 ns). Its unidirectional architecture provides robust forward conduction during overvoltage events while maintaining tight leakage control (≤1.0 µA at VWM) across -65 °C to +185 °C operating range.
The device is rated for 200 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine) and delivers 1500 W peak pulse power (10/1000 µs waveform). Its thermal design supports high-reliability deployment in engine control modules and ADAS sensor units where junction temperature stability is critical.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A-E3/5A (Vishay) | Same VBR (16.0 V), but lower PPPM (400 W), SMA package, higher VC (26.0 V) | Not AEC-Q101 qualified; limited to commercial/industrial use; larger footprint (4.5 mm × 2.7 mm) | Select when cost sensitivity outweighs automotive qualification and surge margin requirements. |

FAQ
What is the clamping voltage of TPC16AHM3/87A at its rated peak pulse current?
The TPC16AHM3/87A has a maximum clamping voltage (VC) of 22.5 V at 66.7 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This value is measured per JEDEC standards and ensures predictable overvoltage limiting for protected circuits. The low VC/VBR ratio of 1.41 reflects efficient silicon design and makes TPC16AHM3/87A especially effective in 12 V automotive systems where voltage headroom is constrained.
Is TPC16AHM3/87A qualified for automotive applications?
Yes, TPC16AHM3/87A is AEC-Q101 qualified and rated for operation up to +185 °C junction temperature. It meets automotive reliability requirements including high-temperature reverse bias (HTRB), temperature cycling (TC), and highly accelerated stress testing (HAST). The HM3 suffix confirms halogen-free, RoHS-compliant construction and JESD201 Class 2 whisker resistance-key for automotive production. TPC16AHM3/87A is explicitly intended for under-hood and ADAS applications where qualification is mandatory.
What does the "HM3/87A" suffix indicate in TPC16AHM3/87A?
The "HM3" denotes Vishay's halogen-free, RoHS-compliant, AEC-Q101-qualified SMPC (TO-277A) package with matte tin-plated leads meeting J-STD-002 solderability and JESD22-B102 wetting balance. The "87A" is the revision code indicating the specific process and test lot configuration per Vishay's internal documentation (Doc. #89056, Rev. 19-Apr-2022). This suffix confirms full compliance with automotive material and reliability standards required for TPC16AHM3/87A deployment.
How does the dual-cathode pinout of TPC16AHM3/87A improve performance?
The dual-cathode configuration (Pins 1 and 2) in TPC16AHM3/87A reduces thermal resistance by providing parallel current paths during surge events, improving power dissipation efficiency and enabling higher IPPM handling. Electrically shorted internally, this layout lowers inductance in the clamping loop versus single-cathode alternatives-critical for sub-10 ns response. The design also enhances mechanical robustness and solder joint reliability in automotive vibration environments, directly supporting TPC16AHM3/87A's AEC-Q101 qualification.
Can TPC16AHM3/87A replace older TVS devices like P6SMB16A in existing designs?
TPC16AHM3/87A is not a direct pin-compatible replacement for P6SMB16A due to different package (TO-277A vs. DO-214AA) and terminal arrangement. While both share 16 V VBR, TPC16AHM3/87A offers 1500 W PPPM (vs. 600 W), lower VC (22.5 V vs. 26.0 V), and AEC-Q101 qualification. Migration requires PCB layout update but delivers superior surge margin and automotive compliance. TPC16AHM3/87A is recommended for new designs targeting ASIL-B/C systems where P6SMB16A would require derating or supplemental protection.
