Product details
Overview
TPC10AHM3/87A 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 electronics protection. It features a 10.0 V nominal breakdown voltage (VBR), 8.55 V stand-off voltage (VWM), clamping voltage of 14.5 V at 103 A peak pulse current, and operates up to +185 °C junction temperature.
For engineers reviewing the TPC10AHM3/87A datasheet, TPC10AHM3/87A pinout, TPC10AHM3/87A application, or TPC10AHM3/87A equivalent, key selection criteria include its AEC-Q101 qualification, low-profile 1.1 mm height, MSL Level 1 rating, unidirectional polarity, and suitability for protecting MOSFETs, sensor signal lines, and IC power rails against inductive switching transients.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve low incremental surge resistance and fast response time under 10/1000 µs surge conditions. Its junction temperature rating of +185 °C and AEC-Q101 qualification confirm design intent for under-hood automotive environments and high-temperature industrial control systems.
The device exhibits a typical temperature coefficient of VBR of +0.064 %/°C and maintains stable clamping performance across -65 °C to +185 °C operating range. Its SMPC (TO-277A) package supports automated placement and meets UL 94 V-0 flammability requirements with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (Nominal) | 10.0 V - Ensures reliable triggering above 8.55 V stand-off while avoiding false trips during normal operation. |
| VC @ IPPM | 14.5 V - Clamps 103 A surge current to safe levels for downstream 12 V rail components like microcontrollers and sensors. |
| PPPM | 1500 W - Sustains high-energy transients from inductive load switching without degradation. |
| TJ max. | +185 °C - Enables deployment in engine control units and powertrain modules where ambient temperatures exceed 125 °C. |
| Package | SMPC (TO-277A) - Low-profile 1.1 mm height supports compact PCB layouts and automated SMT assembly. |

Pinout & Package
Package: SMPC (TO-277A), 3-terminal surface-mount package with cathode band marking on terminal 1 side. Dimensions conform to JEDEC TO-277A standard: 4.80 mm × 3.70 mm × 1.10 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Anode-side reference node for unidirectional clamping | Connected to protected line (e.g., 12 V supply or signal); forms clamping path to terminal 3 (Anode) during overvoltage. |
| 2 (Cathode) | Second cathode terminal - electrically tied to terminal 1 internally | Provides mechanical stability and current-sharing capability; must be routed to same net as terminal 1. |
| 3 (Anode) | Common return path to ground or low-side reference | Connected to system ground or low-impedance return plane; completes clamping loop during transient events. |
Key Features
| Feature | Design Value |
|---|---|
| Junction passivation | Optimized anisotropic rectifier structure ensures stable VBR and low leakage (<20 µA at VWM) over lifetime. |
| Low profile height | 1.1 mm typical - enables use in space-constrained modules such as automotive camera ECUs and motor driver PCBs. |
| MSL Level 1 | No floor life limitation - eliminates bake requirements before reflow, reducing manufacturing overhead. |
| Whisker resistance | Meets JESD 201 Class 2 - prevents tin whisker growth in long-life automotive applications. |
| Automated placement compatibility | Matte tin-plated leads per J-STD-002 - ensures consistent solder wetting and joint reliability in high-volume SMT lines. |

This value is measured per ANSI/IEEE C62.35 standards and ensures downstream 12 V logic and analog components remain within safe operating limits during surge events.
Is the TPC10AHM3/87A suitable for automotive applications?
Yes, the TPC10AHM3/87A is AEC-Q101 qualified and rated for junction temperatures up to +185 °C, making it suitable for under-hood automotive applications including engine control units, body control modules, and ADAS sensor interfaces. Its SMPC package also meets MSL Level 1 and JESD 201 Class 2 whisker resistance requirements.
What does the "HM3/87A" suffix indicate in TPC10AHM3/87A?
The "HM3" denotes halogen-free, RoHS-compliant construction with matte tin-plated leads, while "87A" specifies the revision code per Vishay's internal part numbering convention. The full suffix confirms compliance with AEC-Q101, J-STD-002 solderability, and JESD 22-B102 lead finish standards.
How does the TPC10AHM3/87A compare to the TPC10A base part?
The TPC10AHM3/87A is the fully qualified, production-ready variant of the TPC10A series, incorporating HM3 packaging (halogen-free, RoHS, AEC-Q101) and revision "87A". Unlike generic TPC10A listings, TPC10AHM3/87A guarantees traceable lot data, automotive-grade screening, and documented thermal derating curves per Figure 2 in Document 89056.
What is the recommended PCB pad layout for the TPC10AHM3/87A?
Vishay specifies a mounting pad layout with 6.80 mm × 4.72 mm overall footprint, minimum 1.27 mm solder mask opening, and 4.80 mm × 3.70 mm copper land pattern matching the SMPC (TO-277A) outline. Thermal relief vias under the center pad are recommended for high-power dissipation scenarios.
