Product details
Overview
TPC13HM3/87A 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 13.0 V nominal breakdown voltage (VBR), 11.1 V standoff voltage (VWM), clamping voltage of 18.2 V at 82.4 A peak pulse current, and operates up to +185 °C junction temperature.
For engineers reviewing the TPC13HM3/87A datasheet, TPC13HM3/87A pinout, TPC13HM3/87A application, or TPC13HM3/87A equivalent, key selection criteria include unidirectional surge clamping performance, AEC-Q101 qualification, low-profile 1.1 mm height, MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on automotive ECUs and sensor interfaces.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology optimized for fast transient response (<1 ns) and low incremental surge resistance. Its unidirectional architecture provides forward conduction only during overvoltage events, enabling precise clamping without reverse leakage degradation at VWM.
The device is rated for 1500 W peak pulse power (10/1000 µs waveform), supports 200 A non-repetitive forward surge current (8.3 ms half-sine), and maintains stable VBR across -65 °C to +185 °C operating range with a temperature coefficient of +0.072 %/°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (Nominal) | 13.0 V - Ensures reliable triggering above normal circuit operating voltage while avoiding false activation |
| VWM | 11.1 V - Maximum continuous reverse voltage the device blocks without significant leakage |
| VC @ IPPM | 18.2 V - Clamped voltage seen by protected IC/MOSFET during 82.4 A transient, limiting stress on downstream components |
| PPPM | 1500 W - Peak surge energy handling capacity under standardized 10/1000 µs waveform |
| TJ max. | +185 °C - Enables use in under-hood automotive environments and high-power industrial enclosures |
| Polarity | Unidirectional - Provides forward-biased clamping path only; requires correct orientation in series with protected line |
| MSL Level | Level 1 (per J-STD-020) - No floor life limitation; safe for standard reflow without dry pack or baking |
Pinout & Package
Package: SMPC (TO-277A), surface-mount, 3-terminal configuration with cathode band marking. Dimensions: 4.80 × 3.70 × 1.10 mm (L × W × H), 2.13 mm nominal mounting pad pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Cathode | Connected to protected line side; carries surge current into ground path during clamping |
| Terminal 2 | Cathode | Parallel cathode terminal - electrically tied to Terminal 1; improves current sharing and thermal distribution |
| Terminal 3 | Anode | Connected to system ground; completes clamping path when VBR exceeded |
Key Features
| Feature | Design Value |
|---|---|
| Junction passivation | Optimized anisotropic rectifier process ensures stable VBR and low leakage over lifetime and temperature |
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTOL, TC, and ESD testing per stress test plan |
| Low profile (1.1 mm height) | Enables compact PCB layout in space-constrained modules such as ADAS camera ECUs and motor control boards |
| Matte tin-plated leads | Complies with J-STD-002 and JESD 22-B102 for robust solderability and whisker resistance (JESD 201 Class 2) |
| UL 94 V-0 molding compound | Flame-retardant encapsulation meets safety requirements for industrial and automotive end equipment |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed microcontroller power rails in body control modules against load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS placed between VIN and GND, clamping transients before they reach LDO input. Use Value: Withstands 1500 W surges and maintains VC ≤ 18.2 V, ensuring MCU reset logic remains functional during 100 V/100 ms load dump events. | Use Scenario: Safeguarding analog output lines (e.g., 4–20 mA current loop) of pressure sensors in factory automation PLC I/O modules. IC Role / Device Role / Timing Role: Series-connected TVS on signal line to absorb inductive kickback from solenoid drivers. Use Value: Low clamping voltage and fast response prevent latch-up in op-amp front-ends while supporting operation up to +185 °C ambient. |
| Automotive Camera Module ESD Protection | Motor Drive Gate Driver Protection |
Use Scenario: Shielding MIPI CSI-2 data lines in rear-view camera modules from human-body-model (HBM) ESD and cable discharge events. IC Role / Device Role / Timing Role: TVS placed at connector interface to shunt ESD current away from serializer IC inputs. Use Value: AEC-Q101 qualification and MSL Level 1 ensure robustness through automotive manufacturing flow and field operation. | Use Scenario: Protecting high-side gate driver supply pins (VB) in BLDC motor inverters from Miller-induced voltage spikes. IC Role / Device Role / Timing Role: Clamp device between gate driver VB rail and local ground to limit overshoot during switching transitions. Use Value: 185 °C rating allows placement near MOSFETs; 18.2 V clamping prevents driver IC overvoltage lockout during 600 V bus switching. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A | Lower PPPM (400 W), SMA package (higher thermal resistance), VC = 21.5 V @ 19.9 A | Not AEC-Q101 qualified; limited to commercial/industrial use; unsuitable for under-hood automotive | Select only for cost-sensitive, non-automotive designs where 1500 W surge immunity is not required. |
| TPC13A-HM3_A | Same electrical specs and SMPC package; differs only in packaging suffix (no /87A tape-and-reel variant code) | Identical functional and mechanical behavior; /87A denotes specific reel size and orientation per Vishay ordering convention | TPC13HM3/87A and TPC13A-HM3_A are functionally interchangeable; verify reel logistics match production line requirements. |
Compared with SMAJ13A and TPC13A-HM3_A, TPC13HM3/87A delivers higher surge robustness (1500 W vs. 400 W), automotive qualification, and lower clamping voltage - making it the preferred choice for mission-critical 12 V systems where thermal margin and reliability are prioritized over footprint minimization.

FAQ
What is the exact breakdown voltage tolerance for TPC13HM3/87A?
The TPC13HM3/87A has a specified breakdown voltage (VBR) range of 12.4 V (min) to 13.7 V (max) at 1.0 mA test current, with a nominal value of 13.0 V. This ±5.4% tolerance is defined per ANSI/IEEE C62.35 and verified per the manufacturer's production test flow. The TPC13HM3/87A maintains this specification across its full operating temperature range.
Is TPC13HM3/87A suitable for bidirectional transient protection?
No - the TPC13HM3/87A is strictly unidirectional and must be oriented with its cathode terminals toward the protected line and anode to ground. For bidirectional protection, a separate device such as the SMBJ13CA or equivalent would be required. Using TPC13HM3/87A in reverse polarity risks permanent failure due to forward conduction during negative transients.
Does TPC13HM3/87A require derating at elevated ambient temperatures?
Yes - the peak pulse power (PPPM) of TPC13HM3/87A must be derated linearly above 25 °C ambient, per Figure 2 in the datasheet. At 125 °C ambient, PPPM is reduced to approximately 750 W. The TPC13HM3/87A retains full functionality up to +185 °C junction temperature, but system-level thermal design must ensure that derated limits are respected.
What does the "/87A" suffix indicate in TPC13HM3/87A?
The "/87A" suffix in TPC13HM3/87A denotes a specific tape-and-reel packaging configuration per Vishay's ordering nomenclature: "87" refers to 7-inch diameter reel with 1500-unit quantity, and "A" indicates revision level A of the HM3 halogen-free, RoHS-compliant, AEC-Q101-qualified base package. The TPC13HM3/87A shares identical electrical and mechanical characteristics with TPC13A-HM3_A.
Can TPC13HM3/87A be used in place of SMAJ13A without board changes?
No - although both are unidirectional 13 V TVS diodes, TPC13HM3/87A uses the SMPC (TO-277A) package (4.80 × 3.70 mm), whereas SMAJ13A uses the SMA package (4.5 × 2.7 mm). The different footprints, terminal count (3-pin vs. 2-pin), and thermal pad requirements mean PCB layout modification is necessary. TPC13HM3/87A is not a drop-in replacement for SMAJ13A.
