Product details
Overview
SMPC13A-M3/86A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) in the SMPC (TO-277A) package, designed for clamping inductive-switching transients on power and signal lines. It features a 13.0 V stand-off voltage (VWM), 14.4–15.9 V breakdown voltage (VBR), 21.5 V maximum clamping voltage (VC) at 1.0 A peak pulse current, and 1500 W peak pulse power (PPPM) with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor signal lines in industrial and automotive electronics.
For engineers reviewing the SMPC13A-M3/86A datasheet, SMPC13A-M3/86A pinout, SMPC13A-M3/86A application, or SMPC13A-M3/86A equivalent, key selection criteria include unidirectional polarity, 1.1 mm profile height, MSL Level 1 moisture sensitivity, halogen-free RoHS-compliant construction, and thermal resistance RθJA of 100 °C/W on FR4 PCB.
Technical Context
This device operates as a silicon avalanche diode optimized for fast transient suppression (sub-nanosecond response), with low incremental surge resistance enabling tight clamping under high-current surges. Its unidirectional configuration requires cathode-band orientation for correct series placement across DC rails or signal paths.
The SMPC13A-M3/86A uses a dual-anode/single-cathode layout (SMPCxxA variant) in TO-277A packaging, where both anodes are internally tied and electrically identical - enabling symmetrical mounting and simplified PCB routing for single-rail protection without polarity reversal risk.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13.0 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 14.4 V / 15.9 V at 1.0 mA - ensures reliable avalanche initiation within defined tolerance band |
| VC @ IPPM | 21.5 V at 1.0 A - limits voltage seen by protected downstream circuitry during surge event |
| PPPM | 1500 W (10/1000 μs) - defines energy-handling capability for common lightning/inductive-spike waveforms |
| RθJA | 100 °C/W - junction-to-ambient thermal resistance on standard FR4, 2 oz copper footprint |
| TJ max | +150 °C - maximum allowable junction temperature for sustained operation |
| MSL Level | Level 1 per J-STD-020 - supports lead-free reflow up to 260 °C peak without baking |
Pinout & Package
Package: SMPC (TO-277A), 3-terminal surface-mount case with 1.1 mm typical height, matte tin-plated leads, and cathode band marking. Conforms to JEDEC TO-277A mechanical outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 | Input/Supply rail connection point | Electrically identical to Anode 2; both serve as common input node for unidirectional clamping |
| Anode 2 | Input/Supply rail connection point | Internally tied to Anode 1; enables dual-pad layout flexibility and current sharing |
| Cathode (band end) | Clamped output / ground reference | Connected to system ground or low-impedance return path; defines directionality of suppression |
Key Features
| Feature | Design Value |
|---|---|
| Very low profile (1.1 mm) | Enables use in space-constrained modules such as automotive ECUs and portable industrial sensors |
| Unidirectional polarity | Prevents reverse-bias leakage in DC-powered circuits while delivering precise clamping threshold |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (<1 ns), improving protection margin |
| AEC-Q101 qualification option | Available in HM3 suffix variants (not applicable to SMPC13A-M3/86A); this part is industrial-grade M3 |
| Halogen-free & RoHS-compliant | Meets environmental compliance requirements for global OEM production without material declaration exceptions |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Card |
|---|---|
Use Scenario: Protecting microcontroller GPIOs and CAN transceiver power rails from load-dump and inductive kickback in 12 V vehicle subsystems. IC Role / Device Role / Timing Role: Unidirectional TVS placed between VBAT and GND adjacent to protected IC inputs. Use Value: Clamps transients to ≤21.5 V, preventing latch-up or oxide damage in 3.3 V/5 V logic interfaces while surviving 1500 W surge events. | Use Scenario: Safeguarding 24 V digital input optocouplers and level-shifting circuitry against field-wiring surges and relay coil flyback. IC Role / Device Role / Timing Role: Standoff-rated TVS connected across input terminals upstream of series current-limiting resistor. Use Value: Maintains 13.0 V standoff to avoid false triggering, yet clamps 1 kV/1 A transients within safe voltage window for downstream isolation components. |
| Consumer Appliance Motor Drive Board | Telecom Base Station Sensor Interface |
Use Scenario: Shielding MCU analog front-end and gate drivers from brush-commutator noise and PWM switching spikes in small appliances. IC Role / Device Role / Timing Role: Localized TVS mounted directly at motor driver IC supply pins to minimize loop inductance. Use Value: 1.1 mm height allows placement beneath heat sinks; 1500 W rating handles repetitive commutation spikes without degradation. | Use Scenario: Protecting RS-485 transceivers and temperature/humidity sensor signal lines from ESD and induced lightning surges in outdoor telecom cabinets. IC Role / Device Role / Timing Role: Bidirectionally referenced unidirectional TVS (cathode to GND, anodes to signal line) for asymmetric signal rail protection. Use Value: 21.5 V clamping ensures signal integrity remains intact for ±5 V differential receivers while meeting IEC 61000-4-5 Level 3 surge immunity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A-E3/5A | DO-214AC package; 13 V VWM; 21.5 V VC @ 1.0 A; same PPPM but higher RθJA (150 °C/W) | Larger footprint (4.5 × 2.7 mm vs. 3.7 × 2.2 mm); less suitable for ultra-dense layouts | Choose SMAJ13A-E3/5A only if legacy DO-214AC footprint compatibility is required. |
| SMCJ13A | DO-214AB package; 13 V VWM; 21.5 V VC @ 1.0 A; 1500 W PPPM; RθJA = 120 °C/W | Higher profile (2.6 mm), larger pad area, lower thermal efficiency on same PCB stackup | Prefer SMCJ13A only when higher surge repetition tolerance is needed and board space permits. |
Compared with SMAJ13A-E3/5A and SMCJ13A, the SMPC13A-M3/86A delivers identical electrical clamping performance in a 30 % smaller footprint and 1.1 mm height - critical for next-generation compact modules where thermal resistance is managed via copper pour rather than package size.

FAQ
What is the polarity configuration of SMPC13A-M3/86A?
The SMPC13A-M3/86A is a unidirectional Transient Voltage Suppressor with cathode-marked terminal (band end). Its internal structure features two tied anodes and one cathode, making it suitable for DC rail protection where reverse conduction must be blocked. This differs from bidirectional TVS devices that suppress both polarities.
Does SMPC13A-M3/86A meet AEC-Q101 qualification?
No, SMPC13A-M3/86A carries the industrial-grade M3 suffix and is not AEC-Q101 qualified. AEC-Q101 variants exist only for SMPC22AN through SMPC85AN with HM3 suffix (e.g., SMPC22ANHM3). For automotive applications requiring qualification, select an HM3-part number instead of SMPC13A-M3/86A.
What does the /86A package code indicate for SMPC13A-M3/86A?
The /86A denotes a 7-inch plastic tape-and-reel packaging format containing 1500 units per reel, optimized for high-speed pick-and-place assembly. It specifies carrier tape width, sprocket hole pitch, and component orientation - distinct from /87A (13-inch reel, 6500 units) and does not affect electrical or thermal specifications.
Can SMPC13A-M3/86A be used in bidirectional signal line protection?
No - SMPC13A-M3/86A is strictly unidirectional and must be oriented with cathode toward ground or low-impedance return. For bidirectional signal line protection (e.g., USB, RS-485), a symmetric bidirectional TVS or back-to-back unidirectional pair is required; SMPC13A-M3/86A alone cannot clamp negative-going transients.
What is the maximum clamping voltage of SMPC13A-M3/86A under surge conditions?
The SMPC13A-M3/86A has a maximum clamping voltage (VC) of 21.5 V when subjected to a 1.0 A peak pulse current with a 10/1000 μs waveform. This value is measured at the device terminals and represents the upper limit of voltage imposed on protected circuitry during standardized surge testing.
