Product details
Overview
TPC13AHM3/87A from Vishay General Semiconductor is a unidirectional 1500 W transient voltage suppressor (TVS) in SMPC (TO-277A) package, designed for clamping inductive load switching transients and lightning-induced surges on automotive sensor signal lines and MOSFET gate drivers. It features a 13.0 V nominal breakdown voltage (VBR), 11.1 V stand-off voltage (VWM), and clamps to 18.2 V at 82.4 A peak pulse current (IPPM).
For engineers reviewing the TPC13AHM3/87A datasheet, TPC13AHM3/87A pinout, TPC13AHM3/87A application, or TPC13AHM3/87A equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal derating behavior, SMPC package mechanical data, and direct alternatives for automotive-grade overvoltage protection design.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology with junction passivation optimized for high-reliability operation up to 185 °C junction temperature. Its low incremental surge resistance and fast response time enable effective suppression of sub-microsecond transients induced by relay coil switching or ESD events.
The device operates exclusively in unidirectional mode and is rated for 10/1000 μs waveform testing per ANSI/IEEE C62.35. It meets MSL Level 1 per J-STD-020 and passes JESD201 Class 2 whisker testing, confirming suitability for lead-free reflow assembly in automotive production environments.

Applications
| Automotive Sensor Protection | Power MOSFET Gate Clamp |
|---|---|
Use Scenario: Protecting LIN/CAN bus sensor nodes (e.g., wheel speed, pressure, temperature) from load dump and inductive kickback in 12 V vehicle networks. IC Role / Device Role / Timing Role: Unidirectional TVS placed between signal line and ground to clamp transients below IC absolute maximum ratings. Use Value: Limits clamping voltage to 18.2 V at 82.4 A, ensuring sensor ICs remain within safe operating area during ISO 7637-2 Pulse 1/2a events. |
Use Scenario: Suppressing Miller-induced voltage spikes across gate-source terminals of N-channel power MOSFETs driving solenoids or motors. IC Role / Device Role / Timing Role: Fast-response TVS connected directly at MOSFET gate to absorb nanosecond-scale ringing and prevent false turn-on. Use Value: Sub-1 ns response time and 18.2 V clamping prevent gate oxide breakdown while maintaining <1.1 mm profile for compact gate driver PCB layout. |
| Industrial PLC I/O Protection | Telecom Line Interface Surge Suppression |
Use Scenario: Safeguarding digital input channels of programmable logic controllers against field-wiring transients and electrostatic discharge in factory automation. IC Role / Device Role / Timing Role: Standoff-rated TVS placed at connector entry point to shunt energy before reaching optocoupler or microcontroller input. Use Value: 11.1 V VWM allows compatibility with 5 V and 3.3 V logic levels; 1500 W rating handles repetitive 1 kV/500 A surge tests per IEC 61000-4-5. |
Use Scenario: Front-end protection for Ethernet PHY interfaces or RS-485 transceivers exposed to lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Unidirectional TVS integrated into differential pair routing to limit common-mode overvoltage without distorting signal integrity. Use Value: Low capacitance (<100 pF at VWM) preserves signal rise/fall times; AEC-Q101 qualification supports ruggedized telecom infrastructure deployments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A | Same VBR (13.0 V typ), but lower PPPM = 400 W and higher VC = 21.2 V at 29.3 A | Not qualified to AEC-Q101; limited to commercial/industrial grade | Select when cost sensitivity outweighs automotive qualification and higher surge energy demands |
| TPC13AHM3_A | Identical electrical specs and AEC-Q101 qualification; differs only in packaging code (A vs. 87A revision) | No functional difference; both meet same SMPC mechanical and thermal specifications | Prefer TPC13AHM3_A for new designs where latest revision traceability is required |
Compared with SMAJ13A and TPC13AHM3_A, the TPC13AHM3/87A delivers superior surge robustness (1500 W vs. 400 W), tighter clamping (18.2 V vs. 21.2 V), and full automotive qualification-making it the optimal choice for safety-critical vehicle subsystems requiring long-term reliability under thermal stress.

FAQ
What is the exact breakdown voltage tolerance for TPC13AHM3/87A?
The TPC13AHM3/87A has a guaranteed breakdown voltage range of 12.4 V (minimum) to 13.7 V (maximum) at 1.0 mA test current, with 13.0 V as the nominal value. This ±5.4 % tolerance is confirmed in the Electrical Characteristics table of Vishay document 89056 and applies across the full operating temperature range.
Is TPC13AHM3/87A suitable for bidirectional transient protection?
No, the TPC13AHM3/87A is strictly unidirectional and must be used with correct polarity orientation-cathodes toward the protected line and anode to ground. Bidirectional protection requires a separate part such as the SMBJ13CA; using TPC13AHM3/87A in reverse-biased AC applications will result in forward conduction and failure.
Does TPC13AHM3/87A require derating above 25 °C ambient?
Yes, TPC13AHM3/87A must be derated linearly above 25 °C ambient per Figure 2 in Vishay document 89056: peak pulse power drops to 50 % at 125 °C and reaches zero at 185 °C junction temperature. Designers must calculate actual junction temperature using thermal impedance data and apply appropriate safety margins.
What does the "87A" suffix indicate in TPC13AHM3/87A?
The "87A" suffix denotes the revision code per Vishay's ordering nomenclature: "87" is the internal revision identifier and "A" indicates the first release of that revision. It corresponds to the HM3_X halogen-free, RoHS-compliant, AEC-Q101-qualified variant defined in the Mechanical Data section of document 89056.
Can TPC13AHM3/87A be used in place of SMAJ13A without PCB changes?
No-while both share the same VBR, TPC13AHM3/87A uses the SMPC (TO-277A) package whereas SMAJ13A uses SMA (DO-214AC). Their footprints, thermal pads, and mounting dimensions differ significantly; direct substitution would require PCB layout revision and requalification of thermal performance.
