Product details
Overview
SMPC6.0A-M3/87A 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 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-M3/87A datasheet, SMPC6.0A-M3/87A pinout, SMPC6.0A-M3/87A application, or SMPC6.0A-M3/87A equivalent, this device is selected for robust overvoltage 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 - note that SMPC6.0A-M3/87A is industrial-grade, not AEC-Q101 qualified.
Technical Context
This TVS diode operates in avalanche mode to clamp transient overvoltages above its breakdown threshold while maintaining low leakage (<1000 μA at VWM). Its unidirectional polarity enables integration into DC-biased circuits such as 5 V or 12 V supply rails and signal lines referenced to ground.
The SMPC6.0A-M3/87A uses a planar junction structure in a molded SMPC (TO-277A) package with matte tin-plated leads, rated for MSL level 1 and compatible with lead-free reflow up to 260 °C peak. Thermal resistance is 85–100 °C/W (junction-to-ambient) on FR4 PCB with 2 oz copper.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - maximum continuous reverse operating voltage before significant leakage; defines safe DC bias margin for 5 V systems. |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - guaranteed avalanche onset range; ensures consistent clamping initiation across production lots. |
| VC @ IPPM | 145.6 V at 1000 A (10/1000 μs) - peak clamped voltage seen by protected circuit during worst-case surge event. |
| PPPM | 1500 W - peak transient power handling capability; supports high-energy surges per ISO 7637-2 Pulse 1/2a/5a. |
| IR @ VWM | 1000 μA max - low reverse leakage preserves signal integrity and minimizes standby power loss in battery-powered systems. |
| TJ max | +150 °C - maximum junction temperature rating; enables operation in under-hood or enclosed industrial environments. |
| Package | SMPC (TO-277A) - 3-terminal surface-mount package with 1.1 mm typical height; optimized for automated placement and space-constrained PCBs. |
Pinout & Package
SMPC6.0A-M3/87A uses the SMPC (TO-277A) package: a 3-terminal, unidirectional configuration with cathode band marking. The package has a low profile (1.1 mm typical height), meets UL 94 V-0, and features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 & Anode 2 | Common anode connection | Internally tied anodes allow dual-path surge conduction; both pins must be connected to same potential (e.g., ground or supply rail). |
| Cathode | Transient clamping output | Connected to protected line (e.g., 5 V rail); conducts avalanche current to anode when voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Very low profile (1.1 mm) | Enables use in ultra-thin consumer electronics and stacked PCB assemblies without mechanical interference. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ESD or inductive kickback), improving system immunity. |
| Fast response time (<1 ps) | Clamps transients before sensitive ICs (e.g., microcontrollers or CAN transceivers) experience overstress. |
| MSL Level 1, 260 °C peak | Supports standard lead-free reflow without preconditioning; eliminates moisture-related popcorning risk. |
| Halogen-free, RoHS-compliant | Meets environmental compliance requirements for global electronics manufacturing and end-of-life disposal. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

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 | Same VWM (6.0 V), but SMA package (higher RθJA ≈ 150 °C/W); lower PPPM (400 W); 2-terminal configuration. | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a or high-current load dump. | Select SMAJ6.0A only for cost-sensitive, low-power consumer applications where board space allows larger footprint. |
| SMCJ6.0A | Same VWM and unidirectional function; SMC package (higher power: 1500 W PPPM); 2-terminal; taller profile (2.6 mm). | Higher thermal mass supports repeated surges; less suitable for ultra-low-profile designs. | Choose SMCJ6.0A when sustained surge duty cycle or higher junction-to-ambient thermal margin is required, and 1.1 mm height constraint does not apply. |
Compared with SMAJ6.0A and SMCJ6.0A, the SMPC6.0A-M3/87A uniquely balances 1500 W surge capability with 1.1 mm height and 3-terminal SMPC packaging - making it optimal for space-constrained 5 V rail protection where dual-anode layout simplifies grounding and improves current sharing.

FAQ
What is the polarity configuration of SMPC6.0A-M3/87A?
The SMPC6.0A-M3/87A is a unidirectional TVS diode with a common-cathode configuration: one cathode terminal and two internally connected anode terminals. The cathode band marks the cathode end, and both anode pins must be connected to the same reference potential (typically ground) to ensure proper clamping behavior during transients.
Does SMPC6.0A-M3/87A meet AEC-Q101 qualification?
No, SMPC6.0A-M3/87A is industrial-grade and RoHS-compliant but not AEC-Q101 qualified. AEC-Q101 variants exist only for SMPC22AN through SMPC85AN with HM3 suffix (e.g., SMPC22ANHM3); the SMPC6.0A-M3/87A part number explicitly uses the M3 industrial suffix and falls outside the AEC-Q101 scope defined in the Vishay datasheet.
What is the meaning of the /87A package code in SMPC6.0A-M3/87A?
The /87A suffix denotes the tape-and-reel packaging option: 13-inch diameter plastic tape and reel containing 6500 units. This differs from /86A (7-inch reel, 1500 units). Both /86A and /87A are valid for SMPC5.0A-M3 through SMPC36A-M3 and indicate identical electrical and mechanical specifications - only packaging quantity and reel size differ.
Can SMPC6.0A-M3/87A be used in bidirectional configurations?
No, SMPC6.0A-M3/87A is strictly unidirectional and must be used with correct polarity orientation. Bidirectional operation requires two separate unidirectional devices or a dedicated bidirectional TVS (e.g., SMBJ6.0CA). Using SMPC6.0A-M3/87A in reverse bias beyond its specified IR limit risks permanent damage due to uncontrolled avalanche conduction.
What is the thermal resistance of SMPC6.0A-M3/87A under standard mounting conditions?
SMPC6.0A-M3/87A has a typical junction-to-ambient thermal resistance (RθJA) of 85 °C/W and a maximum of 100 °C/W when mounted on a standard FR4 PCB with 2 oz copper and the recommended pad layout. This value assumes JEDEC 51-2A test conditions and is critical for calculating steady-state power derating above 25 °C ambient.
