Product details
Overview
SMPC10A-M3/86A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) in the SMPC (TO-277A) package, with 10.0 V stand-off voltage (VWM), 17.0 V maximum clamping voltage (VC) at 2.0 A peak pulse current, and 1500 W peak pulse power (PPPM) for 10/1000 μs transients. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics against inductive switching surges.
For engineers reviewing the SMPC10A-M3/86A datasheet, SMPC10A-M3/86A pinout, SMPC10A-M3/86A application, or SMPC10A-M3/86A equivalent, key selection criteria include unidirectional polarity, 1.1 mm profile height, AEC-Q101 qualification eligibility (via HM3 suffix), MSL Level 1 moisture sensitivity, and halogen-free RoHS-compliant construction.
Technical Context
This TVS diode operates as a clamping device that conducts above its breakdown voltage (VBR = 11.1–12.3 V at 10 mA), limiting transient overvoltages to ≤17.0 V while absorbing up to 1500 W of surge energy. Its low incremental surge resistance and fast response time enable effective protection of downstream silicon without adding series impedance or latency.
The SMPC10A-M3/86A uses a dual-anode/single-cathode configuration (anode terminals 1 & 2, cathode terminal K) in the SMPC (TO-277A) package, optimized for high-current surge handling with thermal resistance RθJA ≤ 100 °C/W on FR4 PCB and junction temperature range from –55 °C to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10.0 V - Maximum reverse working voltage before clamping begins; defines safe operating margin below breakdown |
| VBR (min/max) | 11.1 / 12.3 V at 10 mA - Ensures reliable turn-on during transients while avoiding false triggering |
| VC @ IPPM | 17.0 V at 2.0 A - Clamped voltage seen by protected circuit during full-rated 10/1000 μs surge |
| PPPM | 1500 W - Peak transient power absorption capability per JEDEC standard waveform |
| Package | SMPC (TO-277A) - 3-terminal surface-mount package with 1.1 mm typical height and J-STD-020 MSL Level 1 rating |
| Polarity | Unidirectional - Cathode band denotes single conduction direction; requires correct orientation in series with protected line |
| TJ max | +150 °C - Enables operation in under-hood automotive and high-ambient industrial environments |
Pinout & Package
SMPC10A-M3/86A uses the SMPC (TO-277A) package: 3-terminal, surface-mount, low-profile (1.1 mm typical height), matte tin-plated leads, UL 94 V-0 molding compound, and cathode band marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 | Primary anode connection | Electrically tied to Anode 2 internally; both must be connected to same potential (e.g., power rail or signal line) |
| Anode 2 | Secondary anode connection | Redundant anode terminal for enhanced current sharing and lower effective surge resistance |
| Cathode (K) | Clamping output node | Connected to ground or return path; carries full surge current during clamping event |
Key Features
| Feature | Design Value |
|---|---|
| Very low profile (1.1 mm) | Enables use in space-constrained layouts such as automotive ECUs and portable industrial sensors |
| Low incremental surge resistance | Minimizes voltage overshoot during high-di/dt events, improving protection fidelity for sensitive gate drivers |
| MSL Level 1 (260 °C peak) | Supports standard lead-free reflow without baking or special handling requirements |
| Halogen-free & RoHS-compliant | Meets global environmental compliance mandates for automotive and industrial end equipment |
| Unidirectional clamping | Provides precise overvoltage protection on DC-biased lines without affecting normal forward conduction |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A-E3/5AT | DO-214AC package; 10.0 V VWM; 17.0 V VC at 2.0 A; 400 W PPPM (lower surge rating) | Lower power handling limits use to sub-400 W surge environments; less suitable for automotive load-dump | Select when footprint constraints favor SMA and surge energy is ≤400 W |

FAQ
What is the breakdown voltage range for SMPC10A-M3/86A?
The SMPC10A-M3/86A has a specified breakdown voltage (VBR) range of 11.1 V to 12.3 V at 10 mA test current, measured per ANSI/IEEE C62.35 standards. This ensures consistent clamping onset across production lots while maintaining margin above its 10.0 V stand-off voltage. The SMPC10A-M3/86A is designed to remain non-conductive below VWM and enter avalanche conduction only during overvoltage events.
Is SMPC10A-M3/86A AEC-Q101 qualified?
No, SMPC10A-M3/86A is not AEC-Q101 qualified. The AEC-Q101 qualification applies only to SMPCxxAN variants with HM3 suffix (e.g., SMPC22ANHM3). SMPC10A-M3/86A carries the industrial-grade M3 suffix and meets RoHS, halogen-free, and MSL Level 1 requirements-but does not undergo the extended stress testing required for automotive qualification. For AEC-Q101 needs, consider SMPC22ANHM3 or higher-voltage AN-series parts.
What does the /86A package code indicate for SMPC10A-M3/86A?
Per Vishay's ordering information, the /86A suffix specifies a 7-inch diameter plastic tape-and-reel packaging format containing 1500 units per reel. It does not denote a different package variant-the SMPC10A-M3/86A retains the standard SMPC (TO-277A) mechanical outline and electrical characteristics. The /86A code enables automated SMT placement and inventory tracking in high-volume manufacturing environments.
Can SMPC10A-M3/86A be used in bidirectional configurations?
No, SMPC10A-M3/86A is strictly unidirectional and must be oriented with the cathode band toward the reference ground or return path. Bidirectional operation would require two devices in series opposition or a dedicated bidirectional TVS like the SMBJ10CA. Using SMPC10A-M3/86A in reverse bias beyond its 10.0 V stand-off voltage risks premature conduction and unreliable clamping behavior.
What is the thermal resistance of SMPC10A-M3/86A on a standard FR4 PCB?
The SMPC10A-M3/86A exhibits a typical junction-to-ambient thermal resistance (RθJA) of 85 °C/W, with a maximum of 100 °C/W when mounted on a standard FR4 PCB with 2 oz. copper and the recommended pad layout. This value is critical for calculating steady-state temperature rise under continuous power dissipation (PD = 1.25 W at TA = 25 °C) and verifying safe operation within the –55 °C to +150 °C junction temperature range.
