Product details
Overview
TPC10AHM3_A/H from Vishay General Semiconductor is a unidirectional 1500 W transient voltage suppressor (TVS) in TO-277A (SMPC) package, designed for high-reliability automotive and industrial electronics protection. It features a 10.5 V clamping voltage at 103 A peak pulse current, 8.55 V stand-off voltage, 185 °C maximum junction temperature, and AEC-Q101 qualification.
For engineers reviewing the TPC10AHM3_A/H datasheet, TPC10AHM3_A/H pinout, TPC10AHM3_A/H application, or TPC10AHM3_A/H equivalent, key selection criteria include unidirectional clamping performance, MSL Level 1 moisture sensitivity, low-profile 1.1 mm height, and compatibility with automated SMT placement on power rails and signal lines in harsh-environment systems.
Technical Context
The TPC10AHM3_A/H implements passivated anisotropic rectifier technology optimized for fast transient response (<1 ns) and low incremental surge resistance. Its unidirectional architecture provides robust overvoltage clamping only in reverse-biased mode, with breakdown voltage specified at 9.5–10.5 V (1 mA test current).
Designed for automotive-grade reliability, it operates across -65 °C to +185 °C junction temperature range and meets JESD201 Class 2 whisker resistance. The TO-277A (SMPC) package supports high thermal dissipation and conforms to UL 94 V-0 flammability rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.55 V - Maximum continuous reverse operating voltage before leakage exceeds 20 μA |
| VBR (min/max) | 9.5 V / 10.5 V - Breakdown occurs within this range at 1 mA, defining precise overvoltage trigger threshold |
| VC @ IPPM | 14.5 V - Clamped voltage at 103 A peak pulse current, limiting downstream device stress |
| PPPM | 1500 W - Peak pulse power handling capability under 10/1000 μs waveform, critical for load-switching transients |
| TJ max. | +185 °C - Enables operation in under-hood automotive environments without derating |
| Polarity | Unidirectional - Protects only against reverse-polarity surges; requires correct anode/cathode orientation |
| MSL Level | Level 1 - No floor life limitation or bake requirement prior to reflow, simplifying manufacturing flow |
Pinout & Package
TPC10AHM3_A/H is housed in a TO-277A (SMPC) surface-mount package with three terminals: two cathodes (pins 1 and 2) and one anode (pin A). The package has a low profile of 1.1 mm typical height and is optimized for high-density PCB layouts and automated pick-and-place assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Cathode) | Reverse-biased terminal | Connected to protected line; conducts during overvoltage to clamp voltage to VC |
| Pin 2 (Cathode) | Reverse-biased terminal | Parallel cathode path enabling higher surge current sharing and lower effective clamping impedance |
| Pin A (Anode) | Reference/ground terminal | Common return node tied to system ground or low-impedance reference plane |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Lower PPPM (400 W), SMA package, 15.4 V clamping at 25.5 A | Not AEC-Q101 qualified; limited to commercial-grade consumer/industrial use | Choose when cost sensitivity outweighs automotive reliability and surge margin requirements |
| TPC10AHM3_A/I | Identical electrical specs; differs only in packaging-13" tape/reel (6500 pcs) vs. 7" reel (1500 pcs) | No functional or application difference; same board-level performance and qualification | Choose based on production volume and SMT line feed configuration-not electrical substitution |
Compared with SMAJ10A and TPC10AHM3_A/I, the TPC10AHM3_A/H delivers superior surge robustness (1500 W vs. 400 W) and automotive qualification, while TPC10AHM3_A/I offers identical protection in a higher-volume packaging format-making TPC10AHM3_A/H optimal for AEC-Q101-critical designs requiring 7" reel logistics.

FAQ
What is the clamping voltage of the TPC10AHM3_A/H at its rated peak pulse current?
The TPC10AHM3_A/H has a maximum clamping voltage (VC) of 14.5 V at its rated peak pulse current (IPPM) of 103 A under a 10/1000 μs waveform. This value ensures downstream components like microcontrollers and transceivers remain within safe operating voltage limits during surge events. The TPC10AHM3_A/H achieves this with low incremental surge resistance and fast response, making it suitable for protecting sensitive electronics in automotive and industrial applications.
Is the TPC10AHM3_A/H suitable for automotive applications?
Yes, the TPC10AHM3_A/H is AEC-Q101 qualified and rated for junction temperatures up to +185 °C, confirming its suitability for under-hood and other demanding automotive environments. Its TO-277A package meets MSL Level 1 and JESD201 Class 2 whisker resistance requirements. The TPC10AHM3_A/H is explicitly designed for automotive power rail and sensor line protection, including compliance with ISO 7637-2 load-dump immunity testing.
What does the "HM3_A/H" suffix indicate in TPC10AHM3_A/H?
The "HM3_A/H" suffix identifies the package variant and packaging format: HM3 denotes the halogen-free, RoHS-compliant, AEC-Q101-qualified TO-277A (SMPC) package; "A" is the revision code; "H" specifies the 7-inch plastic tape-and-reel delivery mode with 1500 units per reel. This distinguishes TPC10AHM3_A/H from variants like TPC10AHM3_A/I (13-inch reel, 6500 units), while maintaining identical electrical and thermal specifications.
How does the dual-cathode configuration of the TPC10AHM3_A/H improve performance?
The TPC10AHM3_A/H uses a dual-cathode (pins 1 and 2) configuration in its TO-277A package to reduce effective series inductance and distribute surge current, resulting in lower clamping impedance and more consistent voltage limiting during high-di/dt transients. This design enhances energy handling and thermal spreading compared to single-cathode TVS diodes. The TPC10AHM3_A/H leverages this layout to sustain 1500 W peak pulse power without compromising response time or reliability.
Does the TPC10AHM3_A/H require derating at elevated ambient temperatures?
Yes, the TPC10AHM3_A/H must be derated above TA = 25 °C per Figure 2 in the Vishay datasheet (Document 89056). Its peak pulse power decreases linearly with rising ambient temperature, reaching ~70 % of rated 1500 W at 100 °C ambient. Designers must apply this derating curve when sizing protection for high-temperature enclosures. The TPC10AHM3_A/H maintains full functionality up to TJ = +185 °C, but sustained power dissipation depends on PCB copper area and airflow-verified using the transient thermal impedance curve (Figure 5).
