Product details
Overview
TPC15CAHM3/H from Vishay General Semiconductor is a bidirectional 1500 W transient voltage suppressor (TVS) in SMPC (TO-277A) package, designed for high-reliability automotive and industrial surge protection. It features a 14.3–15.8 V breakdown voltage (VBR), 12.8 V stand-off voltage (VWM), 21.2 V clamping voltage at 70.8 A peak pulse current, and AEC-Q101 qualification for under-hood electronics.
For engineers reviewing the TPC15CAHM3/H datasheet, TPC15CAHM3/H pinout, TPC15CAHM3/H application, or TPC15CAHM3/H equivalent, key selection criteria include bidirectional clamping performance, 185 °C junction temperature rating, low-profile 1.1 mm height, MSL Level 1 moisture sensitivity, and halogen-free RoHS-compliant construction.
Technical Context
The TPC15CAHM3/H implements a junction-passivated PAR® design optimized for fast response to transients induced by inductive load switching or ESD events. Its bidirectional structure enables symmetrical clamping across both polarities without external polarity management.
It operates within -65 °C to +185 °C junction temperature range and sustains 1500 W peak pulse power (10/1000 μs waveform) with derating above 25 °C ambient. The device meets JESD201 Class 2 whisker resistance and J-STD-020 MSL Level 1 reflow profile (260 °C peak).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 14.3 V / 15.8 V - ensures reliable triggering above system operating voltage while avoiding false clamping during normal operation |
| VWM | 12.8 V - maximum continuous reverse working voltage compatible with 12 V automotive systems |
| VC @ IPPM | 21.2 V - clamping voltage limits downstream IC/MOSFET stress during 70.8 A surge events |
| PPPM | 1500 W - handles high-energy transients per ISO 7637-2 Pulse 1/2b/5a in automotive environments |
| TJ max | +185 °C - supports placement near heat sources in engine control units and ADAS modules |
| Leakage ID | 1.0 μA @ VWM - negligible standby power loss in always-on sensor interfaces |
Pinout & Package
TPC15CAHM3/H uses the SMPC (TO-277A) surface-mount package: 2-terminal, bidirectional, unmarked polarity, matte tin-plated leads, 1.1 mm typical height, JEDEC-compliant outline with 3.70 mm × 4.80 mm footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode/Cathode (bidirectional) | Either terminal serves as input/output path; no polarity marking required for symmetric clamping |
| Terminal 2 | Anode/Cathode (bidirectional) | Completes the dual-path transient shunt; terminals are electrically interchangeable |
Key Features

|---|---|
| Junction passivation PAR® design | Enhanced long-term reliability under repeated surge stress and high-temperature bias conditions |
| AEC-Q101 qualification | Validated for automotive-grade deployment including engine control, body electronics, and infotainment power rails |
| MSL Level 1 rating | Enables standard SMT reflow without baking or special handling prior to assembly |
| Halogen-free & RoHS-compliant | Meets global environmental compliance requirements for OEM automotive supply chains |
| 1.1 mm profile | Reduces board space and enables placement in tight-constraint zones such as connector interfaces and sensor PCBs |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V power inputs of engine control units against load dump and alternator ripple. IC Role / Device Role / Timing Role: Bidirectional TVS shunting transient energy before it reaches DC-DC converters and microcontrollers. Use Value: Clamps to 21.2 V during 70.8 A surges, preserving downstream components rated for ≤24 V absolute maximum. | Use Scenario: Safeguarding analog signal lines (e.g., CAN, LIN, or analog sensor outputs) from ESD and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance transient suppressor placed directly at connector entry points. Use Value: Sub-1 μA leakage at 12.8 V ensures minimal impact on precision sensor biasing and signal integrity. |

IC Role / Device Role / Timing Role: Standoff-rated TVS absorbing 10/1000 μs surges on VBUS line without affecting USB PD negotiation timing. Use Value: 12.8 V VWM aligns with USB PD 9 V/15 V profiles; 21.2 V clamping prevents overvoltage damage to USB controller ICs. | Use Scenario: Securing 48 V telecom power inputs against lightning-induced surges and switching transients in base station equipment. IC Role / Device Role / Timing Role: Primary-level TVS in front of DC-DC front-end stages to limit surge energy entering power conversion circuitry. Use Value: 1500 W peak power rating provides robust margin against IEC 61000-4-5 Level 4 (4 kV/2 kA) test waveforms. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13CA | Lower PPPM (600 W), higher VC (21.5 V @ 27.1 A), SMB package (higher profile, larger footprint) | Not AEC-Q101 qualified; limited to commercial/industrial use; lower surge handling capacity | Select when cost sensitivity outweighs automotive qualification and 1500 W surge requirement |
| TPC15CAHM3/I | Identical electrical specs and package; differs only in tape-and-reel packaging (6500 pcs/reel vs. 1500 pcs/reel) | No functional difference; same board-level performance and thermal behavior | Choose based on production volume and SMT line feeder compatibility |
Compared with SMBJ13CA and TPC15CAHM3/I, the TPC15CAHM3/H delivers certified automotive reliability, higher surge robustness, and compact SMPC packaging-making it optimal for space-constrained, high-temperature, and safety-critical deployments where AEC-Q101 validation and 1500 W clamping are mandatory.

FAQ
What is the clamping voltage of TPC15CAHM3/H at its rated peak pulse current?
The TPC15CAHM3/H has a maximum clamping voltage (VC) of 21.2 V at its rated peak pulse current (IPPM) of 70.8 A using a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 standards and ensures predictable overvoltage limiting during surge events. The TPC15CAHM3/H maintains this clamping performance across its specified junction temperature range up to +185 °C.
Is TPC15CAHM3/H qualified for automotive applications?
Yes, TPC15CAHM3/H is AEC-Q101 qualified and carries the HM3 suffix indicating compliance with automotive reliability standards, including JESD201 Class 2 whisker resistance and MSL Level 1 reflow capability. Its 185 °C maximum junction temperature and halogen-free RoHS-compliant construction make TPC15CAHM3/H suitable for engine control, ADAS, and body electronics applications.
What package type does TPC15CAHM3/H use, and what are its key mechanical attributes?
TPC15CAHM3/H uses the SMPC (TO-277A) surface-mount package: 2-terminal, bidirectional, unmarked polarity, matte tin-plated leads, and 1.1 mm typical height. Its JEDEC-compliant outline measures 3.70 mm × 4.80 mm, with a low-profile design optimized for automated placement and space-constrained PCB layouts in automotive and industrial systems.
How does the breakdown voltage range of TPC15CAHM3/H compare to its stand-off voltage?
The TPC15CAHM3/H has a breakdown voltage (VBR) range of 14.3 V to 15.8 V at 1 mA test current, while its maximum stand-off voltage (VWM) is 12.8 V. This 1.5 V margin ensures reliable non-conduction during normal 12 V system operation while guaranteeing activation before damaging overvoltage occurs-critical for protecting sensitive downstream ICs and MOSFETs.
Does TPC15CAHM3/H require polarity-aware PCB layout?
No, TPC15CAHM3/H is a bidirectional TVS diode with symmetrical electrical characteristics; its terminals are interchangeable and no polarity marking is present on the SMPC package. This eliminates orientation constraints during PCB layout and automated placement, simplifying design and manufacturing for differential or AC-coupled protection paths.
