Product details
Overview
TPC16AHM3/86A 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 16.0 V nominal breakdown voltage (VBR), 13.6 V stand-off voltage (VWM), 22.5 V clamping voltage (VC) at 66.7 A peak pulse current, and AEC-Q101 qualification for under-hood electronics.
For engineers reviewing the TPC16AHM3/86A datasheet, TPC16AHM3/86A pinout, TPC16AHM3/86A application, or TPC16AHM3/86A equivalent, key selection criteria include its 185 °C maximum junction temperature, low-profile 1.1 mm height, MSL Level 1 rating, and unidirectional polarity optimized for DC rail protection in automotive sensor interfaces and power supply inputs.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver stable clamping performance across temperature. Its 10/1000 µs waveform capability supports IEC 61000-4-5 surge immunity up to 1500 W with low incremental surge resistance and fast response time.
The device operates over -65 °C to +185 °C and meets JESD201 Class 2 whisker resistance. Its SMPC (TO-277A) package enables automated placement and provides UL 94 V-0 compliant molding compound with matte tin-plated terminals solderable per J-STD-002.

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 thermal resistance), no AEC-Q101 qualification | Not suitable for automotive under-hood use; limited to consumer/industrial board-level protection | Select when cost sensitivity outweighs automotive qualification and surge margin requirements |
| TPC16AHE3/86A | Same electrical specs but HM3/86A vs HE3/86A packaging - different reel size and tape configuration (1500 vs 3000 pcs/reel) | Identical functional performance; differs only in logistics and assembly line feed compatibility | Choose based on factory tape-and-reel infrastructure and volume procurement planning |
Compared with SMAJ16A and TPC16AHE3/86A, TPC16AHM3/86A delivers higher surge robustness (1500 W vs 400 W), automotive qualification, and lower thermal impedance via SMPC package - making it optimal for mission-critical 12 V/24 V systems where reliability and space efficiency are prioritized.

FAQ
What is the clamping voltage of TPC16AHM3/86A at its rated peak pulse current?
The TPC16AHM3/86A has a maximum clamping voltage (VC) of 22.5 V when subjected to its rated 10/1000 µs peak pulse current of 66.7 A. This value is measured per JEDEC standards and ensures downstream components remain within safe operating limits during surge events. The clamping performance is guaranteed across the full operating temperature range from -65 °C to +185 °C, and the TPC16AHM3/86A maintains this specification under repetitive surge conditions when derated per Fig. 2 in the datasheet.
Is TPC16AHM3/86A suitable for automotive under-hood applications?
Yes, TPC16AHM3/86A is AEC-Q101 qualified and rated for a maximum junction temperature of +185 °C, making it suitable for under-hood automotive applications such as engine control units, transmission control modules, and ADAS sensor nodes. Its passivated anisotropic rectifier technology ensures stable VBR and low leakage over extended thermal cycling, and the SMPC package supports high-reliability solder joints in vibration-prone environments. The TPC16AHM3/86A meets all required stress tests including temperature humidity bias and mechanical shock per AEC-Q101 Rev G.
What does the "HM3/86A" suffix indicate in TPC16AHM3/86A?
The "HM3/86A" suffix denotes the packaging and revision code: "HM3" specifies halogen-free, RoHS-compliant construction in SMPC (TO-277A) package with matte tin plating and JESD201 Class 2 whisker resistance; "86A" indicates the specific revision level per Vishay's internal documentation control. This suffix also defines the preferred tape-and-reel format - 7-inch diameter plastic tape, 1500 pieces per reel - which aligns with standard SMT feeder configurations. The TPC16AHM3/86A is fully interchangeable electrically and mechanically with other TPC16A variants sharing the same base P/N structure.
How does the dual-cathode configuration of TPC16AHM3/86A improve surge performance?
The dual-cathode (Terminals 1 and 2) configuration in the TPC16AHM3/86A reduces effective series inductance by providing parallel current paths during transient conduction, resulting in faster voltage clamping response and lower overshoot during fast-rising ESD or lightning-induced surges. This layout minimizes parasitic loop area compared to single-cathode packages, improving high-frequency immunity per IEC 61000-4-2 and IEC 61000-4-5. The TPC16AHM3/86A leverages this design to achieve sub-nanosecond response while maintaining low DC resistance and thermal stability under repeated 1500 W pulses.
Does TPC16AHM3/86A require derating at elevated ambient temperatures?
Yes, TPC16AHM3/86A must be derated above TA = 25 °C per Figure 2 in the datasheet, which shows linear derating of peak pulse power from 100 % at 25 °C to approximately 50 % at 125 °C. For example, at 100 °C ambient, the usable PPPM drops to ~750 W. This derating applies to both single-pulse and repetitive surge conditions. The TPC16AHM3/86A's 185 °C TJmax allows continued operation at high ambient temperatures provided PCB copper area and airflow meet Vishay's recommended thermal pad layout (Document 89056, page 4).
