Product details
Overview
TPC16HM3/87A 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 TPC16HM3/87A datasheet, TPC16HM3/87A pinout, TPC16HM3/87A application, or TPC16HM3/87A equivalent, key selection criteria include unidirectional clamping performance under 10/1000 µs transients, AEC-Q101 qualification, MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on high-density PCBs.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of ESD and inductive switching transients. Its unidirectional architecture provides forward conduction path during overvoltage events while maintaining low leakage (<1 µA at VWM) at 25 °C and <10 µA at 150 °C.
The device is rated for 200 A non-repetitive forward surge current (IFSM) and exhibits a typical VF of 3.5 V at 100 A, supporting robust protection in power rail and signal line applications where low clamping voltage and thermal stability are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (Nom) | 16.0 V - precise breakdown threshold ensuring reliable triggering before downstream IC damage |
| VWM | 13.6 V - maximum continuous reverse operating voltage without significant leakage |
| VC @ IPPM | 22.5 V - clamping voltage at 66.7 A, limiting protected circuit stress during 10/1000 µs surge |
| PPPM | 1500 W - peak pulse power handling capability per standard 10/1000 µs waveform |
| TJ max | +185 °C - extended junction temperature rating enabling use in under-hood automotive environments |
| Package | SMPC (TO-277A) - ultra-low-profile surface-mount package with 1.1 mm typical height |
| AEC-Q101 | Qualified - certified for automotive-grade reliability per stress test requirements |
Pinout & Package
TPC16HM3/87A is housed in a 3-terminal SMPC (TO-277A) package with cathode-marked leads and anode center terminal. The package conforms to JEDEC TO-277A mechanical dimensions and supports automated pick-and-place assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Reverse-biased terminal | Connected to protected line; conducts during overvoltage to shunt energy to ground |
| 2 (Cathode) | Reverse-biased terminal | Parallel cathode path for enhanced current sharing and lower dynamic impedance |
| 3 (Anode) | Common reference terminal | Typically tied to system ground or low-impedance return path for clamping action |
Key Features
| Feature | Design Value |
|---|---|
| Passivated anisotropic rectifier technology | Enables stable VBR tolerance (±5 %) and low dynamic impedance across temperature and lifetime |
| MSL Level 1 per J-STD-020 | Zero floor life limitation - no baking required prior to reflow, simplifying manufacturing flow |
| Halogen-free, RoHS-compliant construction | Meets environmental compliance requirements for automotive and industrial end equipment |
| JESD 201 Class 2 whisker resistance | Ensures long-term solder joint integrity in high-vibration or thermally cycled applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A | Lower PPPM (400 W), SMA package (higher thermal resistance), VC = 26.0 V at 24.7 A | Not AEC-Q101 qualified; limited to consumer/industrial use below 150 °C | Choose SMAJ16A only when surge energy demand is low and automotive qualification is unnecessary. |
| TPC16H | Same electrical specs but HM3/87A suffix indicates halogen-free, RoHS-compliant, AEC-Q101-qualified version with JESD 201 Class 2 whisker resistance | TPC16H lacks full automotive qualification and may not meet MSL Level 1 or high-temp reliability testing | Select TPC16HM3/87A over TPC16H when automotive production, long-term reliability, or strict environmental compliance is required. |
Compared with SMAJ16A and TPC16H, the TPC16HM3/87A delivers higher surge power handling, guaranteed automotive qualification, and superior thermal robustness-making it the preferred choice for mission-critical 12 V and 24 V systems where failure modes must be rigorously controlled.

FAQ
What is the exact breakdown voltage range for TPC16HM3/87A?
The TPC16HM3/87A has a specified breakdown voltage (VBR) range of 15.2 V (min) to 16.8 V (max) at 1.0 mA test current, with a nominal value of 16.0 V. This tight ±5 % tolerance ensures consistent triggering behavior across production lots and temperature extremes, critical for predictable protection in automotive power domains.
Is TPC16HM3/87A suitable for bidirectional transient suppression?
No, TPC16HM3/87A is strictly unidirectional. It conducts only when reverse-biased beyond VBR, making it appropriate for DC power rails and single-polarity signal lines. For bidirectional protection (e.g., data lines), a separate symmetric TVS like SMBJ16CA would be required-not the TPC16HM3/87A.
Does TPC16HM3/87A require derating above 25 °C ambient?
Yes, TPC16HM3/87A must be derated per Figure 2 in Vishay document 89056. At 85 °C ambient, its peak pulse power drops to ~75 % of 1500 W (≈1125 W); at 125 °C, it falls to ~50 %. Derating ensures safe operation within the 185 °C maximum junction temperature limit and maintains clamping performance integrity.
What does the "HM3/87A" suffix indicate in TPC16HM3/87A?
The "HM3/87A" suffix denotes halogen-free, RoHS-compliant construction (HM3), AEC-Q101 qualification, and JESD 201 Class 2 whisker resistance (87A). It distinguishes this variant from non-automotive versions like TPC16H and confirms compliance with automotive supply chain material and reliability standards.
Can TPC16HM3/87A replace SMAJ16A in existing designs without layout changes?
No-TPC16HM3/87A uses SMPC (TO-277A) package while SMAJ16A uses SMA. Their footprints differ significantly: SMPC has 3 terminals in a triangular arrangement (cathode-cathode-anode), whereas SMA is 2-terminal. PCB redesign and validation are required to substitute TPC16HM3/87A for SMAJ16A.
