Product details
Overview
SMPC6.5A-M3/87A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) in the SMPC (TO-277A) package, rated for 6.5 V stand-off voltage (VWM), 7.22–7.98 V breakdown voltage (VBR), and 133.9 V clamping voltage (VC) at 500 A peak pulse current (IPPM). It delivers 1500 W peak pulse power (PPPM) with 1.25 W steady-state power dissipation and operates from –55 °C to +150 °C - used for protecting MOSFETs and sensor signal lines against inductive switching transients in industrial and automotive electronics.
For engineers reviewing the SMPC6.5A-M3/87A datasheet, SMPC6.5A-M3/87A pinout, SMPC6.5A-M3/87A application, or SMPC6.5A-M3/87A equivalent, key selection criteria include unidirectional polarity, 1500 W 10/1000 μs surge capability, low-profile 1.1 mm height, MSL Level 1 rating, and halogen-free RoHS-compliant industrial-grade construction.
Technical Context
This device functions as a unidirectional avalanche diode designed to clamp transient overvoltages before they damage downstream circuitry. Its low incremental surge resistance and fast response time enable effective suppression of ESD and load-switching spikes on DC power rails and low-voltage signal paths.
The SMPC6.5A-M3/87A uses a dual-anode/single-cathode configuration in the SMPC (TO-277A) package, where the cathode band identifies the cathode terminal. Thermal performance is characterized by RθJA ≤ 100 °C/W (FR4, 2 oz copper) and RθJM ≤ 3 °C/W, supporting reliable operation under repetitive surge conditions when mounted per JEDEC 51-2A/51-14 standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.5 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 7.22 V / 7.98 V at 10 mA - guaranteed avalanche onset range for design margining |
| VC @ IPPM | 133.9 V at 500 A - clamped voltage during full-rated 10/1000 μs surge, defining protection window |
| PPPM | 1500 W - peak transient power handling capability per standard 10/1000 μs waveform |
| PD (TA = 25 °C) | 1.25 W - steady-state power dissipation limit on FR4 PCB with standard footprint |
| TJ max. | +150 °C - maximum junction temperature enabling use in under-hood or high-ambient industrial environments |
| Package | SMPC (TO-277A) - 3-terminal surface-mount package with 1.1 mm typical height and MSL Level 1 rating |
Pinout & Package
SMPC6.5A-M3/87A uses the SMPC (TO-277A) package: a 3-terminal surface-mount case with dual anodes and single cathode. The cathode is marked by a band on the body. Mounting pad layout follows JEDEC TO-277A standard dimensions (e.g., 4.80 × 4.40 mm body, 6.80 mm overall pad length).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 | Primary anode connection | Connected to protected line (e.g., VCC rail or signal input); shares current path with Anode 2 |
| Anode 2 | Secondary anode connection | Parallel anode terminal enabling higher surge current sharing and lower effective dynamic resistance |
| Cathode | Common cathode terminal | Connected to ground or reference plane; polarity band denotes this terminal; defines unidirectional conduction path |
Key Features
| Feature | Design Value |
|---|---|
| Very low profile | 1.1 mm typical height - enables use in space-constrained modules and thin consumer enclosures |
| Low incremental surge resistance | Enables tighter clamping voltage control under high-current transients, reducing stress on protected ICs |
| MSL Level 1 rating | Compatible with standard SMT reflow profiles up to 260 °C peak - no pre-baking required |
| Halogen-free & RoHS-compliant | M3 suffix confirms industrial-grade compliance with environmental and safety regulations |
| Matte tin-plated leads | Solderable per J-STD-002 and JESD 22-B102 - ensures robust intermetallic formation and long-term joint reliability |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting analog sensor signal lines (e.g., pressure, temperature) in engine control units from load-dump and inductive kickback. IC Role / Device Role / Timing Role: Unidirectional TVS placed between sensor output and microcontroller ADC input to clamp transients below absolute maximum ratings. Use Value: Prevents latch-up or permanent damage to 3.3 V/5 V ADC inputs while maintaining signal integrity via low leakage (<1500 μA at 6.5 V). |
Use Scenario: Safeguarding digital input channels on programmable logic controller (PLC) modules exposed to relay coil switching noise. IC Role / Device Role / Timing Role: TVS connected across input terminals to shunt induced surges before reaching optocoupler or level-shifter ICs. Use Value: Ensures system uptime by absorbing 1500 W transients without degradation, meeting IEC 61000-4-4 level 4 immunity requirements. |
| DC Power Rail Protection | Consumer Device USB Port Protection |
Use Scenario: Clamping voltage spikes on 5 V or 12 V DC distribution rails in motor drive subsystems. IC Role / Device Role / Timing Role: TVS placed at power entry point upstream of DC-DC converters and gate drivers to suppress inductive switching events. Use Value: Limits rail overshoot to ≤133.9 V during 500 A surges, preventing overvoltage failure of downstream MOSFETs and controllers. |
Use Scenario: Protecting USB 2.0 data lines and VBUS in portable audio devices from ESD and hot-plug transients. IC Role / Device Role / Timing Role: Dual-anode configuration allows shared placement on D+ and D− lines with common cathode to ground. Use Value: Delivers sub-nanosecond response and <1 μA leakage at 5 V, preserving signal integrity while passing IEC 61000-4-2 ±15 kV contact discharge testing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.5A | DO-214AC package; 600 W PPPM; higher RθJA (~150 °C/W); single-anode configuration | Limited to lower-energy transients; less suitable for high-repetition or high-ambient thermal environments | Choose SMAJ6.5A only if board space permits larger footprint and surge energy is ≤600 W |
| SMCJ6.5A | DO-214AB package; 1500 W PPPM; same clamping voltage but 2.3 mm height; higher thermal mass | Better sustained surge handling but incompatible with ultra-low-profile assemblies requiring ≤1.1 mm height | Choose SMCJ6.5A when mechanical clearance allows >1.1 mm and enhanced thermal inertia is prioritized over profile |
Compared with SMAJ6.5A and SMCJ6.5A, the SMPC6.5A-M3/87A uniquely combines 1500 W surge rating, 1.1 mm height, and dual-anode architecture - making it optimal for compact, high-energy industrial and automotive PCBs where both space and robustness are critical.

FAQ
What is the polarity configuration of the SMPC6.5A-M3/87A?
The SMPC6.5A-M3/87A is a unidirectional TVS diode with dual-anode and single-cathode terminals. The cathode is identified by a band on the package body. This configuration allows it to conduct only during positive transients relative to ground, making it suitable for DC rail and signal-line protection where reverse voltage is not expected.
Does the SMPC6.5A-M3/87A meet automotive qualification standards?
No - the SMPC6.5A-M3/87A carries the M3 suffix, indicating industrial-grade halogen-free and RoHS-compliant construction. For AEC-Q101 qualification, Vishay offers the SMPC6.5AN-HM3 variant (not SMPC6.5A-M3/87A), which is only available in the AN-series family starting from SMPC22AN.
What is the meaning of the /87A package code in SMPC6.5A-M3/87A?
The /87A suffix specifies the reel packaging format: 13-inch diameter plastic tape and reel, containing 6500 units. This differs from /86A (7-inch reel, 1500 units) and does not affect electrical or thermal performance - it is purely a logistics and handling designation for automated assembly lines.
Can SMPC6.5A-M3/87A be used in bidirectional transient protection applications?
No - the SMPC6.5A-M3/87A is strictly unidirectional. Bidirectional protection requires either two back-to-back unidirectional devices or a dedicated bidirectional TVS such as the SMBJ6.5CA. Using SMPC6.5A-M3/87A in reverse-biased configurations risks catastrophic failure due to lack of reverse avalanche capability.
What is the maximum allowable mounting temperature for SMPC6.5A-M3/87A during reflow soldering?
The SMPC6.5A-M3/87A meets MSL Level 1 per J-STD-020 and supports lead-free reflow profiles with a maximum peak temperature of 260 °C. No pre-baking is required, and the device maintains integrity through standard IPC/JEDEC G-level thermal cycling when mounted on FR4 with 2 oz copper.
