Product details
Overview
SMPC6.5A-M3/86A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) in the SMPC (TO-277A) package, designed for clamping transient overvoltages on power and signal lines. It features a 6.5 V stand-off voltage (VWM), 7.22–7.98 V breakdown voltage (VBR) at 10 mA, 133.9 V clamping voltage at 500 A peak pulse current, 1500 W peak pulse power (10/1000 μs), and operates from –55 °C to +150 °C junction temperature.
For engineers reviewing the SMPC6.5A-M3/86A datasheet, SMPC6.5A-M3/86A pinout, SMPC6.5A-M3/86A application, or SMPC6.5A-M3/86A equivalent, this device is selected for robust ESD and surge protection in automotive sensor interfaces, industrial I/O modules, and DC power rail conditioning where low-profile mounting and AEC-Q101-compliant alternatives are not required.
Technical Context
The SMPC6.5A-M3/86A uses an avalanche diode structure optimized for fast response (<1 ns) to transient events such as inductive load switching and ESD. Its unidirectional polarity enables integration into DC-biased circuits without reverse conduction during normal operation.
Thermal performance is defined with RθJA = 85–100 °C/W (FR4, 2 oz copper), supporting 1.25 W steady-state dissipation at 25 °C ambient. The device is halogen-free, RoHS-compliant, and qualified to JESD201 Class 2 for tin whisker resistance.
Key Specifications

Pinout & Package
SMPC6.5A-M3/86A is housed in the SMPC (TO-277A) package: a 3-terminal surface-mount case with cathode band marking, matte tin-plated leads, and UL 94 V-0 molding compound. Dimensions conform to JEDEC TO-277A standard (4.80 × 3.70 × 1.10 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 | Primary anode connection | Connected to protected line (e.g., +12 V rail); forms one side of unidirectional avalanche path |
| Anode 2 | Secondary anode connection | Internally tied to Anode 1; provides dual-pad mechanical stability and current sharing in high-surge designs |
| Cathode | Clamping output terminal | Connected to ground or low-impedance return; carries full surge current during clamping event |
Key Features
| Feature | Design Value |
|---|---|
| Very low profile (1.1 mm typical height) | Enables placement beneath low-clearance shields or in stacked-board assemblies without interference |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ISO 7637-2 Pulse 1/2a) |
| Meets MSL Level 1 (260 °C peak reflow) | Supports single-pass lead-free reflow without moisture-related failure risk |
| Unidirectional configuration | Prevents reverse leakage in DC-biased applications while maintaining fast turn-on on positive surges |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load-dump and inductive kickback in 12 V vehicle subsystems. IC Role / Device Role / Timing Role: Unidirectional TVS placed between sensor supply line and chassis ground to clamp transients before they reach sensitive analog front-ends. Use Value: Clamps 500 A surges to ≤133.9 V, preventing latch-up or damage to 3.3 V/5 V signal-conditioning ICs downstream. | Use Scenario: Safeguarding digital input channels on programmable logic controllers exposed to relay coil flyback and motor drive noise in factory automation cabinets. IC Role / Device Role / Timing Role: Mounted across 24 V DC input terminals to absorb repetitive 10/1000 μs surges induced by contactor switching. Use Value: 1500 W peak power rating sustains repeated surge events without degradation, extending field reliability beyond 100,000 cycles. |
| Consumer Power Adapter Protection | Telecom DC Power Rail Protection |
Use Scenario: Suppressing ESD and line transients on secondary-side 5 V/9 V/12 V outputs of wall adapters used in smart home hubs and IoT gateways. IC Role / Device Role / Timing Role: Placed between regulated output and USB/DC barrel jack to protect connected devices during hot-plug or lightning-induced coupling. Use Value: 6.5 V VWM ensures no conduction during normal regulation, while 133.9 V VC limits stress on downstream USB PD controllers. | Use Scenario: Guarding 48 V intermediate bus rails in telecom base station power supplies against lightning-induced surges entering via external cabling. IC Role / Device Role / Timing Role: Used in parallel with bulk capacitance on 48 V distribution nodes to limit transient voltage rise during 10/1000 μs surge events. Use Value: Low thermal resistance (RθJM ≤ 3 °C/W) allows efficient heat transfer to heatsink-equipped PCBs, sustaining 1.25 W continuous dissipation during intermittent surges. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A-E3/5A | Lower VWM (6.0 V), lower PPPM (400 W), SMA package (higher RθJA ≈ 150 °C/W) | Less suitable for high-current 12 V automotive transients; better for low-power signal-line protection | Select when board space permits larger footprint and surge energy is ≤400 W |
| SMCJ6.5A | Same VWM/VBR/VC specs, but SMC (DO-214AB) package (2.5 mm height, higher surge rating up to 3000 W) | Requires more vertical clearance; preferred for industrial systems needing >1500 W margin | Select when higher peak power headroom and proven field history in harsh environments are prioritized |
Compared with SMAJ6.0A-E3/5A and SMCJ6.5A, the SMPC6.5A-M3/86A delivers identical clamping performance in a 1.1 mm low-profile package optimized for automated placement-making it ideal for space-constrained, high-volume consumer and industrial PCBs where 1500 W surge handling is sufficient.

FAQ
What is the maximum clamping voltage of SMPC6.5A-M3/86A under standard test conditions?
The SMPC6.5A-M3/86A has a maximum clamping voltage (VC) of 133.9 V when subjected to a 500 A peak pulse current with a 10/1000 μs waveform. This value is measured at the device terminals and defines the upper voltage limit imposed on protected circuitry during surge events. The SMPC6.5A-M3/86A maintains this clamping performance across its specified operating temperature range.
Is SMPC6.5A-M3/86A AEC-Q101 qualified?
No, SMPC6.5A-M3/86A is not AEC-Q101 qualified. It carries the "M3" suffix indicating halogen-free, RoHS-compliant, industrial-grade construction. AEC-Q101 qualification applies only to variants with the "HM3" suffix (e.g., SMPC22ANHM3), which are restricted to the SMPC22AN–SMPC85AN family per Vishay documentation. The SMPC6.5A-M3/86A remains suitable for non-automotive industrial and consumer applications.
What does the /86A package code indicate for SMPC6.5A-M3/86A?
Per Vishay's ordering information, the /86A suffix denotes a 7-inch diameter plastic tape-and-reel packaging format containing 1500 units per reel. This is the standard delivery mode for SMPC5.0A-M3 through SMPC36A-M3 variants and ensures compatibility with high-speed pick-and-place equipment. The /86A code does not affect electrical or thermal specifications of the SMPC6.5A-M3/86A device itself.
How does the SMPC6.5A-M3/86A differ from bidirectional TVS diodes?
The SMPC6.5A-M3/86A is unidirectional and functions only during positive voltage transients relative to its cathode. Unlike bidirectional TVS devices, it does not suppress negative-going surges-making it appropriate for DC-biased lines like 12 V power rails or sensor supply outputs. Its unidirectional design yields lower leakage current and tighter VBR tolerance than equivalent bidirectional parts, which is confirmed in the SMPC6.5A-M3/86A datasheet's electrical characteristics table.
Can SMPC6.5A-M3/86A be used in parallel to increase surge current handling?
Parallel use of SMPC6.5A-M3/86A devices is not recommended without current-sharing design measures. Variations in VBR (7.22–7.98 V) and dynamic impedance can cause uneven current division during surges, leading to premature failure of the lower-VBR unit. For higher current capability, Vishay specifies the SMPC10A–SMPC36A variants or recommends the SMCJ6.5A in the larger SMC package instead of paralleling SMPC6.5A-M3/86A units.
