Product details
Overview
TPC9.1HM3/86A from Vishay General Semiconductor is a unidirectional 1500 W transient voltage suppressor (TVS) in SMPC (TO-277A) package, designed for clamping inductive load switching transients on automotive sensor signal lines. It features a breakdown voltage of 8.65–9.55 V at 1.0 mA, clamping voltage of 13.4 V at 112 A peak pulse current, and operates up to +185 °C junction temperature.
For engineers reviewing the TPC9.1HM3/86A datasheet, TPC9.1HM3/86A pinout, TPC9.1HM3/86A application, or TPC9.1HM3/86A equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, SMPC package dimensions, and automotive-grade surge protection design guidance for sensor interface circuits.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology optimized for low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of ESD and load-dump transients per ISO 7637-2 and IEC 61000-4-2. Its unidirectional polarity and 7.78 V stand-off voltage support reliable DC bias operation in sensor supply or signal return paths.
The device is rated for 200 A non-repetitive forward surge current (8.3 ms half-sine), exhibits 0.060 %/°C temperature coefficient of VBR, and meets JESD201 Class 2 whisker resistance and MSL Level 1 moisture sensitivity requirements - confirming suitability for high-reliability automated SMT assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 8.65 / 9.10 / 9.55 V at 1.0 mA - defines precise clamping onset threshold under transient stress |
| VWM | 7.78 V - maximum continuous reverse working voltage before leakage exceeds 50 μA |
| VC @ IPPM | 13.4 V at 112 A - peak clamped voltage during 10/1000 μs surge, limiting downstream IC stress |
| PPPM | 1500 W - peak pulse power handling capability for automotive load-dump and inductive kick events |
| TJ max. | +185 °C - enables placement near hot engine-control electronics without derating |

| AEC-Q101 | Qualified - validated for automotive applications including powertrain and ADAS sensor interfaces |
Pinout & Package
TPC9.1HM3/86A is housed in the SMPC (TO-277A) package: a 3-terminal, single-anode dual-cathode configuration with matte tin-plated leads, UL 94 V-0 molding compound, and JESD201 Class 2 whisker resistance. Total height is 1.1 mm typical; footprint matches JEDEC TO-277A standard.

FAQ
What is the exact breakdown voltage range for TPC9.1HM3/86A?
The TPC9.1HM3/86A has a guaranteed breakdown voltage range of 8.65 V to 9.55 V when tested at 1.0 mA DC current, per Vishay Document Number 89056. This specification is measured after applying the test current for 300 μs and reflects the device's precise clamping threshold under standardized conditions. The nominal VBR is 9.10 V, and the temperature coefficient is +0.060 %/°C.
Is TPC9.1HM3/86A qualified for automotive use?
Yes, TPC9.1HM3/86A is AEC-Q101 qualified and explicitly designated as automotive grade in the Vishay datasheet. It meets JESD201 Class 2 whisker resistance, MSL Level 1, and operates reliably from -65 °C to +185 °C junction temperature - making it suitable for engine control, ADAS, and body electronics applications where long-term reliability under thermal cycling is mandatory.
What does the "86A" suffix indicate in TPC9.1HM3/86A?
The "86A" suffix in TPC9.1HM3/86A denotes the packaging variant: 13-inch diameter plastic tape-and-reel with 6500 units per reel. It shares identical electrical characteristics, SMPC (TO-277A) package, and AEC-Q101 qualification with TPC9.1HM3_A (7-inch reel, 1500 units). No circuit or thermal differences exist between the two part numbers.
What is the clamping voltage of TPC9.1HM3/86A under surge conditions?
The TPC9.1HM3/86A clamps to a maximum of 13.4 V when subjected to its rated 10/1000 μs peak pulse current of 112 A. This value is measured at the device terminals under standardized test conditions and represents the upper limit of voltage seen by downstream circuitry during worst-case transient events, ensuring compatibility with 5 V and 3.3 V logic interfaces.
Can TPC9.1HM3/86A be used in bidirectional configurations?
No, TPC9.1HM3/86A is strictly unidirectional and must be oriented with cathodes toward the protected line and anode to ground or low-side reference. It lacks symmetrical breakdown behavior and will not clamp effectively on positive-going transients applied to the anode. For bidirectional protection, a separate device such as the SMBJ9.0CA or dual-series configuration is required.
