Product details
Overview
TPC15HM3/86A 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 overvoltage protection. It features a 15.0 V nominal breakdown voltage (VBR), 12.8 V stand-off voltage (VWM), clamping voltage of 21.2 V at 70.8 A peak pulse current, and operates up to +185 °C junction temperature.
For engineers reviewing the TPC15HM3/86A datasheet, TPC15HM3/86A pinout, TPC15HM3/86A application, or TPC15HM3/86A equivalent, this device is selected for robust ESD/surge protection on power rails and signal lines where low-profile mounting, AEC-Q101 qualification, and fast response (<1 ns) are critical design requirements.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with optimized junction passivation for stable clamping under repetitive surge stress. Its unidirectional configuration enables integration into DC power paths without reverse-bias leakage concerns, and its 10/1000 µs waveform rating aligns with IEC 61000-4-5 Level 4 immunity testing.
The device delivers 1500 W peak pulse power dissipation with low incremental surge resistance (Rdyn ≈ 0.29 Ω derived from VC/IPPM), enabling effective suppression of inductive switching transients and load-dump events in 12 V and 24 V automotive systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (Nominal) | 15.0 V - Ensures reliable triggering above normal operating voltage while avoiding false clamping during transients. |
| VWM | 12.8 V - Maximum continuous DC or RMS voltage the device blocks without significant leakage (≤1 µA). |
| VC @ IPPM | 21.2 V - Clamped voltage seen by protected circuit during 70.8 A 10/1000 µs surge, limiting downstream stress. |
| PPPM | 1500 W - Peak surge power handling capability per single 10/1000 µs pulse, compliant with IEC 61000-4-5. |
| TJ max. | +185 °C - Enables operation in under-hood automotive environments and high-power industrial enclosures. |
| Package | SMPC (TO-277A) - Surface-mount, low-profile (1.1 mm height), AEC-Q101 qualified, MSL Level 1. |
Pinout & Package
SMPC (TO-277A) is a 3-terminal surface-mount package with cathode band marking on terminal 1. The device has two cathodes (pins 1 and 2) tied internally to the same cathode node, and one anode (pin 3). This dual-cathode layout supports high-current surge conduction with reduced thermal resistance and improved PCB layout symmetry.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Primary cathode connection | Internally bonded to die cathode; marked with cathode band line; used for primary current return path. |
| 2 (Cathode) | Secondary cathode connection | Parallel cathode terminal sharing same node as pin 1; reduces bond wire inductance and improves surge current distribution. |
| 3 (Anode) | Anode connection | Input terminal for transient energy; connects to protected line (e.g., battery rail or signal trace) requiring clamping. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance per JESD22-A108. |
| Junction passivation | Stabilizes VBR over lifetime and prevents parametric drift under high humidity or bias stress. |
| Low profile (1.1 mm height) | Enables use in space-constrained modules such as ADAS ECUs, body control units, and compact power supplies. |
| MSL Level 1 rating | Allows unlimited floor life and reflow compatibility without dry-pack or baking requirements. |
| Halogen-free & RoHS-compliant | Meets automotive material compliance standards (Vishay Doc. 99912) and environmental regulations. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed microcontrollers and CAN transceivers from load dump and jump-start transients. IC Role / Device Role: Unidirectional TVS placed between battery rail and input filter capacitor to clamp surges before LDOs or DC-DC converters. Use Value: Limits clamped voltage to 21.2 V during 70.8 A surge, preventing damage to downstream 3.3 V/5 V logic and ensuring system-level ISO 16750-2 compliance. | Use Scenario: Safeguarding analog sensor outputs (e.g., pressure, temperature) connected to ADC inputs in factory automation PLCs. IC Role / Device Role: TVS mounted at sensor connector entry point to shunt ESD (IEC 61000-4-2 ±8 kV contact) and cable-induced transients. Use Value: Sub-1 ns response time and 21.2 V clamping prevent latch-up or offset shift in precision op-amps and SAR ADC front-ends. |
| Telecom DC Power Input Protection | Consumer Device USB Power Path Protection |
Use Scenario: Securing 48 V DC input of PoE-powered network switches against lightning-induced surges on outdoor cabling. IC Role / Device Role: Primary TVS on main DC input rail upstream of DC-DC conversion stage. Use Value: 1500 W peak power rating handles multi-pulse surge events per IEC 61000-4-5, while 185 °C TJ rating supports sealed enclosure thermal profiles. | Use Scenario: Adding overvoltage resilience to USB-C power delivery circuits in portable monitors or docking stations. IC Role / Device Role: Unidirectional TVS on VBUS line to absorb hot-plug transients and adapter switching noise. Use Value: Low 12.8 V VWM ensures no interference with 5–20 V PD negotiation, while 21.2 V VC protects USB-PD controllers rated to 24 V absolute maximum. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A | Same VBR (15.0 V) and PPPM (400 W), but lower surge rating (400 W vs. 1500 W); SMA package (higher thermal resistance). | Not suitable for automotive load dump; limited to low-energy ESD or signal-line protection. | Select only for cost-sensitive consumer applications with <50 A surge exposure. |
| TPC15A (non-HM3 suffix) | Identical electrical specs, but lacks halogen-free, RoHS-compliant, and AEC-Q101 qualifications; different packaging and traceability. | Restricted to non-automotive industrial use where material compliance and qualification are not mandated. | Choose TPC15HM3/86A when automotive PPAP, material declarations, or long-term supply continuity are required. |
Compared with SMAJ15A and TPC15A, the TPC15HM3/86A provides 3.75× higher peak power handling, AEC-Q101 validation, and halogen-free construction-making it the only option qualified for under-hood automotive deployment and high-reliability industrial power rail protection.

FAQ
What is the exact breakdown voltage tolerance for TPC15HM3/86A?
The TPC15HM3/86A has a specified breakdown voltage (VBR) range of 14.3 V (min) to 15.8 V (max) at 1.0 mA test current, with 15.0 V as the nominal value. This ±5% tolerance is confirmed in the Electrical Characteristics table of Vishay document 89056 and applies across the full operating temperature range.
Is TPC15HM3/86A suitable for bidirectional transient protection?
No, TPC15HM3/86A is strictly unidirectional and must be used only in DC applications where reverse voltage is blocked. For bidirectional protection, Vishay offers separate devices such as the TPSC15A series; using TPC15HM3/86A in AC or bipolar signal paths risks permanent failure due to reverse conduction beyond its rated IR.
Does TPC15HM3/86A require derating at elevated ambient temperatures?
Yes, TPC15HM3/86A must be derated per Figure 2 in Vishay document 89056: peak pulse power decreases linearly above 25 °C ambient, reaching ~70% of 1500 W at +100 °C ambient. Designers must apply this derating when calculating worst-case surge margin in high-temperature enclosures.
What is the meaning of the "86A" suffix in TPC15HM3/86A?
The "86A" suffix denotes the revision code and tape-and-reel packaging variant per Vishay's ordering nomenclature. Specifically, "86A" identifies the HM3 halogen-free, RoHS-compliant, AEC-Q101-qualified version supplied in 7-inch plastic tape and reel (1500 units per reel), as defined in the Ordering Information section of document 89056.
Can TPC15HM3/86A be used in parallel to increase surge current handling?
No-TPC15HM3/86A is not characterized or recommended for parallel operation. Mismatched VBR tolerances and dynamic impedance can cause current imbalance, leading to premature failure of one device. For higher surge ratings, select a higher-rated single device such as TPC20A or TPC22A instead.
