Product details
Overview
TPC16HM3/86A 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 standoff voltage of 13.6 V, breakdown voltage of 15.2–16.8 V at 1 mA, clamping voltage of 22.5 V at 66.7 A, and junction temperature rating up to +185 °C.
For engineers reviewing the TPC16HM3/86A datasheet, TPC16HM3/86A pinout, TPC16HM3/86A application, or TPC16HM3/86A equivalent, key selection criteria include peak pulse power handling (1500 W), low-profile 1.1 mm height, AEC-Q101 qualification, and compatibility with automated SMT placement on automotive-grade PCBs.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for fast response (<1 ns) and low incremental surge resistance. Its unidirectional architecture provides robust clamping during positive-going transients while maintaining low leakage (<1 μA at 13.6 V, 25 °C) and stable VBR temperature coefficient (0.078 %/°C).
The device operates across -65 °C to +185 °C junction temperature range and meets MSL Level 1 per J-STD-020. Its SMPC (TO-277A) package supports high thermal dissipation and complies with UL 94 V-0 flammability rating and JESD 201 Class 2 whisker resistance.
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 | Lower PPPM (400 W), SMA package (higher inductance, larger footprint), VBR = 17.8–19.7 V | Not AEC-Q101 qualified; limited to commercial/industrial use; unsuitable for automotive under-hood locations | Select when cost sensitivity outweighs power handling and automotive qualification requirements |
| TPC16A | Identical electrical specs and SMPC package; differs only in packaging suffix (no HM3/86A tape-and-reel variant code) | No functional difference; same AEC-Q101 qualification, thermal rating, and clamping behavior | Choose TPC16A for non-automated prototyping or small-batch evaluation where reel coding is not required |
Compared with SMAJ16A and TPC16A, the TPC16HM3/86A delivers automotive-grade reliability via AEC-Q101 qualification and 1500 W surge capacity in a low-profile SMPC package-enabling compact, high-density layouts in safety-critical vehicle subsystems where alternative parts lack either power rating, qualification, or form factor alignment.

FAQ
What is the clamping voltage of the TPC16HM3/86A under a 10/1000 µs surge?
The TPC16HM3/86A has a maximum clamping voltage (VC) of 22.5 V when subjected to a peak pulse current (IPPM) of 66.7 A using the standardized 10/1000 µs waveform. This value is measured at TA = 25 °C and ensures protected circuits remain below critical voltage thresholds during surge events. The TPC16HM3/86A maintains this clamping performance across its full operating temperature range due to its low VBR temperature coefficient of 0.078 %/°C.
Is the TPC16HM3/86A AEC-Q101 qualified?
Yes, the TPC16HM3/86A is fully AEC-Q101 qualified for automotive applications. This qualification covers stress tests including high-temperature operating life, temperature cycling, humidity bias, and mechanical shock-all performed on the actual SMPC (TO-277A) packaged device. The TPC16HM3/86A is intended for use in engine control units, body electronics, and ADAS modules where automotive-grade reliability is mandatory.
What does the 'HM3/86A' suffix indicate in TPC16HM3/86A?
The 'HM3' portion denotes Vishay's halogen-free, RoHS-compliant, AEC-Q101-qualified eSMP® package variant with matte tin-plated leads and JESD 201 Class 2 whisker resistance. The '/86A' suffix specifies the tape-and-reel packaging configuration: 7-inch diameter reel, 1500 units per reel, and revision code 'A'. This coding ensures traceability and matches Vishay's official ordering nomenclature for volume production.
Can the TPC16HM3/86A be used in bidirectional protection circuits?
No, the TPC16HM3/86A is strictly unidirectional and must not be used in bidirectional configurations. Its internal structure supports clamping only for positive transients applied between cathode and anode. For bidirectional protection, Vishay offers separate part numbers such as the TPSMB16CA series. Using the TPC16HM3/86A in reverse-biased or AC-coupled applications may result in catastrophic failure or uncontrolled leakage.
What is the maximum junction temperature rating for the TPC16HM3/86A?
The TPC16HM3/86A has a maximum junction temperature (TJ max.) rating of +185 °C, verified per AEC-Q101 test conditions. This allows reliable operation in high-ambient environments such as engine compartments, power inverters, and industrial motor drives. Derating curves in the datasheet show that at 125 °C ambient, the device retains >85 % of its 1500 W peak pulse power capability, making it suitable for thermally demanding designs.
