Product details
Overview
SMPC8.0A-M3/86A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) in the eSMP® SMPC (TO-277A) package, designed for clamping inductive-switching transients on power and signal lines. It features a 8.0 V stand-off voltage (VWM), 8.89–9.83 V breakdown voltage (VBR), 13.6 V maximum clamping voltage (VC) at 50 A IPPM, 1500 W peak pulse power (10/1000 µs), and operates from –55 °C to +150 °C.
For engineers reviewing the SMPC8.0A-M3/86A datasheet, SMPC8.0A-M3/86A pinout, SMPC8.0A-M3/86A application, or SMPC8.0A-M3/86A equivalent, this device is selected for robust overvoltage protection in automotive sensor interfaces, industrial I/O modules, DC power rail conditioning, and consumer power supply input stages where low-profile mounting and AEC-Q101-grade reliability are not required - but high surge immunity and fast response (<1 ns) are critical.
Technical Context
The SMPC8.0A-M3/86A employs an avalanche diode structure optimized for transient suppression with low incremental surge resistance and sub-nanosecond response time. Its unidirectional polarity enables integration into DC-biased circuits without reverse conduction concerns, and its TO-277A package supports dual-anode/cathode terminal configuration for flexible PCB layout routing.
Thermal performance is defined per JEDEC 51-2A (RθJA ≤ 100 °C/W) and JEDEC 51-14 (RθJM ≤ 3 °C/W), enabling reliable operation under repetitive surge conditions when mounted on standard FR4 with 2 oz copper. The device meets MSL Level 1 and JESD201 Class 2 whisker resistance requirements.
Key Specifications

Use Value: Enables reliable operation at up to 1500 W peak pulse power without derating, maintaining >10⁵ surge cycles per channel. |
| Consumer Power Supply Input | DC Motor Drive Protection |
Use Scenario: Input-stage transient suppression on AC/DC adapter secondary-side 5–12 V rails exposed to lightning-induced surges via long cables. IC Role / Device Role / Timing Role: Primary overvoltage clamp on regulated DC output, placed immediately after rectification and before bulk capacitor. Use Value: Limits voltage excursion to ≤13.6 V during 10/1000 µs surges, preventing overvoltage failure of downstream LDOs or USB-PD controllers. | Use Scenario: Flyback energy absorption across H-bridge MOSFETs driving brushed DC motors in robotics or HVAC actuators. IC Role / Device Role / Timing Role: Bidirectional-capable unidirectional clamp across motor terminals, referenced to common ground to suppress both polarity flyback spikes. Use Value: Withstands repeated 50 A pulses at 13.6 V clamping, extending MOSFET lifetime and eliminating need for external snubbers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0A | Same VWM (8.0 V), same PPPM (1500 W), but SMA package (higher RθJA ≈ 150 °C/W) and larger footprint (4.5 × 2.7 mm vs. 4.8 × 3.7 mm). | Less suitable for high-density layouts or thermally constrained environments due to lower power density and higher thermal resistance. | Select SMAJ8.0A only if legacy SMA footprint compatibility is required and thermal margin exceeds 25 °C/W. |
| SMCJ8.0A | Same VWM and clamping, but SMC package (7.1 × 6.2 mm), higher PD (5.0 W), and RθJA ≈ 40 °C/W - significantly better thermal performance but 3× larger area. | Better for high-repetition-rate surge environments (e.g., factory automation), but incompatible with space-limited designs. | Choose SMCJ8.0A when sustained surge duty cycle exceeds 1 Hz and PCB real estate allows larger footprint. |
Compared with SMAJ8.0A and SMCJ8.0A, the SMPC8.0A-M3/86A delivers optimal balance of low-profile packaging (1.1 mm height), industry-standard thermal resistance (≤100 °C/W), and full 1500 W surge rating - making it preferred for next-generation compact industrial and automotive modules where volume and thermal management are co-constrained.

FAQ
What is the maximum clamping voltage of SMPC8.0A-M3/86A at its rated peak pulse current?
The SMPC8.0A-M3/86A has a maximum clamping voltage (VC) of 13.6 V when subjected to its rated peak pulse current (IPPM) of 50 A under the standard 10/1000 µs waveform. This value is measured with the cathode terminal mounted on heatsink per the datasheet test condition and defines the upper voltage limit imposed on protected circuitry during surge events.
Is SMPC8.0A-M3/86A qualified to AEC-Q101 for automotive use?
No, SMPC8.0A-M3/86A is not AEC-Q101 qualified. It carries the industrial-grade M3 suffix and base P/N-M3 designation. AEC-Q101 qualification applies only to SMPCxxAN variants (e.g., SMPC22ANHM3), which use the HM3 suffix and are explicitly listed for automotive applications in the Vishay documentation.
What does the /86A package code indicate for SMPC8.0A-M3/86A?
Per Vishay ordering information, the /86A suffix denotes a 7-inch diameter plastic tape-and-reel packaging format containing 1500 units per reel. It specifies delivery mode and quantity - not electrical or mechanical differentiation - and is fully compatible with standard SMT pick-and-place equipment calibrated for 8 mm carrier tape.
Can SMPC8.0A-M3/86A be used in bidirectional transient protection circuits?
No, SMPC8.0A-M3/86A is strictly unidirectional. Its internal structure and polarity marking (cathode band) support clamping only in the reverse-biased direction. For bidirectional protection, two SMPC8.0A-M3/86A devices must be connected in series opposition, or a dedicated bidirectional TVS (e.g., SMPC8.0CA) should be selected instead.
What is the thermal resistance junction-to-ambient (RθJA) for SMPC8.0A-M3/86A under standard mounting conditions?
The SMPC8.0A-M3/86A has a maximum RθJA of 100 °C/W when mounted on a standard FR4 PCB with 2 oz copper and the recommended pad layout per JEDEC TO-277A. Its typical RθJA is 85 °C/W, enabling reliable operation up to 1.25 W steady-state dissipation at 25 °C ambient.
