Product details
Overview
TPC43HM3/86A from Vishay General Semiconductor is a unidirectional 1500 W transient voltage suppressor (TVS) in SMPC (TO-277A) package, designed for clamping inductive switching transients and lightning-induced surges on automotive sensor signal lines and MOSFET gate drivers. It features a 43.0 V nominal breakdown voltage (VBR), 36.8 V standoff voltage (VWM), 59.3 V maximum clamping voltage (VC) at 25.3 A peak pulse current, and AEC-Q101 qualification for under-hood automotive use.
For engineers reviewing the TPC43HM3/86A datasheet, TPC43HM3/86A pinout, TPC43HM3/86A application, or TPC43HM3/86A equivalent, key selection criteria include unidirectional polarity, 185 °C junction temperature rating, low-profile 1.1 mm height, MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on high-reliability automotive PCBs.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology to achieve low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of ESD and load-dump transients before sensitive downstream circuitry is damaged. Its junction passivation and robust thermal design support continuous operation up to TJ = 185 °C.
The device operates exclusively in unidirectional mode and is optimized for clamping in circuits where reverse-biased leakage must remain below 1.0 μA at VWM = 36.8 V and below 15 μA at TJ = 150 °C - critical for low-power sensor interfaces and always-on automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (Nominal) | 43.0 V - precise breakdown threshold ensures reliable triggering before IC damage in 36–40 V system rails |
| VWM | 36.8 V - maximum continuous reverse operating voltage compatible with 36 V automotive battery systems |
| VC @ IPPM | 59.3 V - clamping voltage at 25.3 A limits stress on protected MOSFETs or microcontrollers during ISO 7637-2 Pulse 5a events |
| PPPM | 1500 W - peak pulse power handling supports single-event surge immunity per ISO 16750-2 and SAE J1113-11 |
| TJ max. | 185 °C - enables under-hood deployment without derating in engine control units and transmission modules |
| Package | SMPC (TO-277A) - 3-terminal surface-mount package with cathode band marking and 1.1 mm profile for space-constrained layouts |
| AEC-Q101 | Qualified - certified for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard |
Pinout & Package
TPC43HM3/86A uses the SMPC (TO-277A) package: a 3-terminal, unidirectional surface-mount configuration with cathode terminals on pins 1 and 2, and anode on pin 3. The package has a low-profile height of 1.1 mm and conforms to JEDEC TO-277A mechanical dimensions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Cathode) | Reverse-biased terminal | Connected to protected line (e.g., sensor output); forms clamping path to ground when transient exceeds VWM |
| Pin 2 (Cathode) | Reverse-biased terminal | Internally tied to Pin 1; provides dual-cathode layout for enhanced current sharing and lower thermal resistance |
| Pin 3 (Anode) | Reference/ground terminal | Connected to system ground plane; completes clamping loop and defines reference for VBR and VC |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ43A | Same VBR (43 V), but SMA package (higher profile: 2.29 mm), lower PPPM (400 W), no AEC-Q101 qualification | Limited to consumer/industrial use; unsuitable for under-hood automotive due to thermal and qualification gaps | Select only for cost-sensitive non-automotive designs where 1500 W surge immunity is not required. |
| TPC43HM3/86A | Identical electrical specs and AEC-Q101 qualification; differs only in packaging variant (86A suffix denotes tape-and-reel configuration) | No functional difference - same die, same SMPC package, same performance in all automotive applications | TPC43HM3/86A is the preferred choice for production automotive programs requiring full qualification traceability and low-profile mounting. |
Compared with SMAJ43A and TPC43HM3/86A itself, the TPC43HM3/86A delivers 3.7× higher peak power handling, 1.1 mm lower profile, and automotive-grade reliability - making it the only option qualified for direct replacement in AEC-Q101-compliant systems without layout or thermal redesign.

FAQ
What is the exact breakdown voltage tolerance for TPC43HM3/86A?
The TPC43HM3/86A has a specified breakdown voltage range of 40.9 V (min) to 45.2 V (max) at 1.0 mA test current, with a nominal value of 43.0 V. This ±5% tolerance is confirmed in the Electrical Characteristics table of Vishay document 89056 and applies directly to the TPC43HM3/86A variant without interpolation or extrapolation.
Is TPC43HM3/86A pin-compatible with other devices in the TPCxxA family?
Yes - all TPCxxA devices, including TPC43HM3/86A, share identical SMPC (TO-277A) package dimensions, pin assignment (cathode-cathode-anode), and thermal pad layout. This allows direct substitution across the family for different VBR values without PCB revision, provided layout accommodates the same 3-terminal footprint.
Does TPC43HM3/86A meet ISO 7637-2 and ISO 16750-2 surge immunity standards?
The TPC43HM3/86A is not certified to ISO 7637-2 or ISO 16750-2 as a standalone component, but its 1500 W peak pulse power, 59.3 V clamping voltage at 25.3 A, and 185 °C junction rating enable circuit-level compliance when properly applied in automotive power nets and signal lines per those standards' test waveforms.
What does the "86A" suffix indicate in TPC43HM3/86A?
The "86A" suffix in TPC43HM3/86A identifies the packaging configuration: 13-inch diameter plastic tape-and-reel with 6500 units per reel (package code "I"), and revision "A" for the halogen-free, RoHS-compliant, AEC-Q101-qualified HM3 base construction - consistent with Vishay's ordering nomenclature in document 89056.
Can TPC43HM3/86A be used in bidirectional configurations?
No - TPC43HM3/86A is strictly unidirectional and lacks symmetrical breakdown characteristics. It must be oriented with cathodes toward the protected line and anode to ground. For bidirectional protection, Vishay offers separate part numbers such as TPBxxA series; TPC43HM3/86A cannot be repurposed or paralleled to achieve bidirectional behavior.
