Product details
Overview
SMPC6.0A-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 transient overvoltages on power and signal lines. It features a 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 145.6 V clamping voltage (VC) at 1000 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with 10/1000 μs waveform.
For engineers reviewing the SMPC6.0A-M3/86A datasheet, SMPC6.0A-M3/86A pinout, SMPC6.0A-M3/86A application, or SMPC6.0A-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-compatible variants are not required but industrial-grade halogen-free compliance is mandated.
Technical Context
This TVS diode operates as a unidirectional clamping device, leveraging avalanche breakdown to limit transient voltages above its VWM threshold. Its low incremental surge resistance and fast response time ensure effective suppression of inductive switching spikes and lightning-induced surges on 5–12 V rails.
The SMPC6.0A-M3/86A uses a dual-anode/single-cathode configuration (Anode 1, Anode 2, Cathode) in the SMPC (TO-277A) package, enabling symmetric thermal dissipation when mounted with either anode or cathode on heatsink - confirmed by Vishay's "Anode on heatsink / Cathode on heatsink" test conditions in the electrical characteristics table.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC bias margin for 5 V systems. |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - Tight breakdown window ensures predictable turn-on and minimal variation across production lots. |
| VC @ IPPM | 145.6 V at 1000 A - Clamping voltage under 10/1000 μs surge defines worst-case voltage seen by protected downstream ICs. |
| PPPM | 1500 W - Peak pulse power rating determines survivability against high-energy transients like ISO 7637-2 Pulse 1/2a/5a. |
| IR @ VWM | 1000 μA max - Low leakage preserves efficiency in battery-powered or high-impedance sensing circuits. |
| Package | SMPC (TO-277A) - 3-terminal surface-mount package with 1.1 mm typical height, MSL Level 1, J-STD-020 compliant. |
| Polarity | Unidirectional - Band-marked cathode enables single-direction surge shunting; requires correct orientation in series with protected line. |
Pinout & Package
SMPC6.0A-M3/86A is housed in the SMPC (TO-277A) package: a 3-terminal, low-profile surface-mount outline conforming to JEDEC TO-277A, with matte tin-plated leads, UL 94 V-0 molding compound, and cathode band marking per datasheet Figure 5.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 | Primary anode connection | One of two parallel anode terminals; connects to protected line input side; enables symmetrical thermal path when mounted on heatsink. |
| Anode 2 | Secondary anode connection | Second parallel anode terminal; electrically identical to Anode 1; used to distribute surge current and reduce localized heating. |
| Cathode | Cathode (band-marked) | Common clamping node tied to ground or low-impedance return; polarity must match PCB silkscreen band orientation. |
Key Features
| Feature | Design Value |
|---|---|
| Very low profile (1.1 mm typical height) | Enables use in space-constrained applications such as portable electronics and stacked PCB assemblies without mechanical interference. |
| Unidirectional clamping architecture | Provides precise overvoltage protection on positive-going transients while blocking reverse conduction - ideal for DC power rails and unidirectional data lines. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ESD, relay bounce), improving protection margin for sensitive MOSFET gates and microcontroller I/O. |
| Halogen-free, RoHS-compliant, industrial grade (M3 suffix) | Meets environmental compliance requirements for commercial and industrial equipment without requiring AEC-Q101 qualification. |
| MSL Level 1, 260 °C peak reflow | Supports standard lead-free SMT assembly processes without moisture sensitivity concerns or baking requirements. |
Applications
| Automotive Sensor Interface | Industrial PLC Digital Input |
|---|---|

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 | DO-214AC (SMA) package; 1.5 mm height; 600 W PPPM; 10.3 V VC @ 62.7 A IPPM | Lower power handling and higher clamping voltage; suitable only for lower-energy transients (e.g., IEC 61000-4-2 ESD). | Select SMAJ6.0A only when board height budget allows >1.1 mm and surge energy is limited to ≤600 W. |
| SMCJ6.0A | DO-214AB (SMC) package; 2.6 mm height; 1500 W PPPM; 10.3 V VC @ 1000 A IPPM | Same power rating and clamping performance, but larger footprint and height; higher thermal mass improves sustained surge tolerance. | Choose SMCJ6.0A when PCB layout permits larger area and enhanced thermal cycling reliability is prioritized over profile. |
Compared with SMAJ6.0A and SMCJ6.0A, the SMPC6.0A-M3/86A delivers identical 1500 W surge capability in a 1.1 mm profile - making it optimal for ultra-thin consumer and automotive modules where SMAJ lacks power and SMCJ exceeds height constraints.

FAQ
What is the maximum clamping voltage of the SMPC6.0A-M3/86A under surge conditions?
The SMPC6.0A-M3/86A has a maximum clamping voltage (VC) of 145.6 V when subjected to a 1000 A peak pulse current with a 10/1000 μs waveform. This value is measured with the cathode on heatsink per Vishay's test condition, and defines the upper voltage limit imposed on protected circuitry during worst-case transient events. The SMPC6.0A-M3/86A maintains this clamping performance across its specified junction temperature range.
Is the SMPC6.0A-M3/86A AEC-Q101 qualified?
No, the SMPC6.0A-M3/86A is not AEC-Q101 qualified. It carries the industrial-grade M3 suffix and is halogen-free and RoHS-compliant, but AEC-Q101 qualification applies only to SMPCxxAN variants (e.g., SMPC22AN-M3/H) per the Vishay datasheet note on page 3. For automotive applications requiring AEC-Q101, SMPC6.0A-M3/86A must be replaced with a qualified variant or alternative series.
What does the /86A package code indicate for SMPC6.0A-M3/86A?
The /86A suffix denotes the preferred tape-and-reel packaging option: 7-inch diameter plastic tape and reel containing 1500 units. This format supports automated SMT placement and is compatible with standard pick-and-place feeders. The /86A code is distinct from /87A (13-inch reel, 6500 units) and does not affect electrical or thermal specifications of the SMPC6.0A-M3/86A device itself.
How is the polarity marked on the SMPC6.0A-M3/86A package?
The SMPC6.0A-M3/86A uses a cathode band marking on the package body to denote the cathode terminal, consistent with industry-standard diode polarity identification. As shown in the mechanical drawing on page 5 of the Vishay datasheet, the band aligns with the cathode pin in the SMPC (TO-277A) outline. Correct orientation is critical - reversing the SMPC6.0A-M3/86A will prevent clamping during positive transients.
What is the thermal resistance of the SMPC6.0A-M3/86A under standard mounting conditions?
When mounted on a standard FR4 PCB with 2 oz. copper and the recommended pad layout, the SMPC6.0A-M3/86A exhibits a typical junction-to-ambient thermal resistance (RθJA) of 85 °C/W, with a maximum of 100 °C/W per JEDEC 51-2A. This value supports continuous power dissipation up to 1.25 W at 25 °C ambient, and derates linearly above that temperature as shown in Figure 2 of the Vishay datasheet.
