Product details
Overview
TPC10AHM3_A/I from Vishay General Semiconductor is a unidirectional 1500 W transient voltage suppressor (TVS) in TO-277A (SMPC) package, designed for robust overvoltage protection of sensitive electronics. It features a 10.5 V clamping voltage at 103 A peak pulse current, 9.5–10.5 V breakdown voltage range, and 8.55 V stand-off voltage - optimized for automotive-grade circuits requiring AEC-Q101 qualification and 185 °C junction temperature capability.
For engineers reviewing the TPC10AHM3_A/I datasheet, TPC10AHM3_A/I pinout, TPC10AHM3_A/I application, or TPC10AHM3_A/I equivalent, key selection criteria include its 1500 W peak pulse power rating, low-profile 1.1 mm height, MSL Level 1 moisture sensitivity, and uni-directional clamping behavior in high-reliability automotive and industrial power line protection.
Technical Context
The TPC10AHM3_A/I implements passivated anisotropic rectifier technology with junction passivation optimized for stable avalanche performance under repetitive surge stress. Its thermal design supports continuous operation up to TJ = 185 °C and meets JESD 201 Class 2 whisker resistance requirements.
It delivers fast response time (<1 ns), low incremental surge resistance, and excellent clamping ratio (VC/VBR ≈ 1.4), making it suitable for protecting MOSFETs, ICs, and sensor signal lines against inductive switching transients and lightning-induced surges per IEC 61000-4-5.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 9.5 V / 10.5 V - defines reliable avalanche initiation threshold across production lot and temperature range |
| VWM | 8.55 V - maximum continuous reverse operating voltage before leakage exceeds 20 μA |
| VC @ IPPM | 14.5 V - clamped voltage during 103 A 10/1000 μs surge, limiting downstream device stress |
| PPPM | 1500 W - peak pulse power handling capacity under standardized surge waveform |
| IPPM | 103 A - maximum non-repetitive surge current supported at 25 °C ambient |
| TJ max. | 185 °C - enables operation in under-hood automotive environments without derating |
| Polarity | Uni-directional - protects only against positive-going transients on anode-to-cathode path |
Pinout & Package
Package: TO-277A (SMPC), surface-mount, 3-terminal configuration with cathode-anode-cathode layout. Dimensions conform to JEDEC TO-277A standard; typical height 1.1 mm; matte tin-plated leads solderable per J-STD-002.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Lower PPPM (400 W), SMA package, 10.0–11.1 V VBR, 16.0 V VC @ 25.6 A | Not AEC-Q101 qualified; limited to consumer/industrial use below 150 °C | Choose for cost-sensitive non-automotive designs where surge energy is lower and board space permits larger footprint |
| TPC10AHM3_A/H | Identical electrical specs and TO-277A package; differs only in tape-and-reel packaging (7" vs. 13" reel, 1500 vs. 6500 units) | No functional or application difference - same reliability, thermal, and electrical performance | Select based on production volume and SMT line feeder compatibility rather than circuit design requirements |
Compared with SMAJ10A and TPC10AHM3_A/H, the TPC10AHM3_A/I offers superior surge handling (1500 W vs. 400 W), automotive qualification, and tighter VC/VBR ratio - making it the preferred choice for high-energy, mission-critical protection where layout space is constrained and thermal margin is critical.

FAQ
What is the clamping voltage of the TPC10AHM3_A/I under maximum surge conditions?
The TPC10AHM3_A/I has a maximum clamping voltage (VC) of 14.5 V when subjected to its rated 103 A peak pulse current (IPPM) using the standard 10/1000 μs waveform. This value is measured at TA = 25 °C and ensures downstream components see no more than 14.5 V during worst-case surge events. The TPC10AHM3_A/I maintains this clamping performance across its qualified temperature range, supporting robust protection in automotive and industrial settings.
Is the TPC10AHM3_A/I suitable for automotive applications?
Yes, the TPC10AHM3_A/I is AEC-Q101 qualified and rated for junction temperatures up to 185 °C, making it suitable for under-hood and powertrain-related automotive applications. Its TO-277A package meets JESD 201 Class 2 whisker resistance requirements, and its construction uses halogen-free, RoHS-compliant materials. The TPC10AHM3_A/I is explicitly listed in Vishay's automotive-grade TVS portfolio for use in ECUs, body control modules, and ADAS power supplies.
How does the TPC10AHM3_A/I differ from the TPC10AHM3_A/H variant?
The TPC10AHM3_A/I and TPC10AHM3_A/H share identical electrical specifications, thermal ratings, mechanical dimensions, and qualification status. Their only difference is packaging: TPC10AHM3_A/I ships in 13" diameter plastic tape-and-reel with 6500 units per reel, while TPC10AHM3_A/H uses 7" reels with 1500 units. No circuit or layout changes are needed when substituting between them - the TPC10AHM3_A/I is a direct packaging alternative for high-volume SMT lines.
What is the standoff voltage (VWM) and why is it important for the TPC10AHM3_A/I?
The TPC10AHM3_A/I has a maximum working standoff voltage (VWM) of 8.55 V, meaning it remains in high-impedance blocking mode below this voltage with leakage <20 μA at 25 °C. This parameter ensures reliable operation on 8 V nominal rails (e.g., automotive 9–10 V systems) without false triggering or excessive power loss. Exceeding VWM risks premature conduction, so proper margin between system operating voltage and VWM is essential - the TPC10AHM3_A/I provides 1.45 V headroom over an 8.55 V rail.
Does the TPC10AHM3_A/I require derating at elevated ambient temperatures?
Yes, the TPC10AHM3_A/I must be derated above TA = 25 °C per Figure 2 in Vishay document 89056. Its peak pulse power (PPPM) decreases linearly to ~50 % at TA = 100 °C and reaches zero at TA = 175 °C. Derating ensures safe operation within thermal limits; for example, at 85 °C ambient, PPPM is reduced to ~900 W. The TPC10AHM3_A/I's 185 °C TJmax enables continued functionality where other TVS devices would fail, but system-level thermal design remains critical.
