Product details
Overview
SMPC7.0A-M3/86A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) in the eSMP® Series, designed for clamping inductive-switching transients on 7.0 V DC power rails. It delivers 1500 W peak pulse power (10/1000 μs), clamps at ≤12.0 V under 200 A surge, and features a low-profile SMPC (TO-277A) package with 1.1 mm typical height-ideal for space-constrained automotive and industrial sensor power lines.
For engineers reviewing the SMPC7.0A-M3/86A datasheet, SMPC7.0A-M3/86A pinout, SMPC7.0A-M3/86A application, or SMPC7.0A-M3/86A equivalent, this page provides verified electrical parameters, thermal derating behavior, polarity-sensitive mounting guidance, and AEC-Q101-comparable alternatives for robust overvoltage protection design.
Technical Context
This TVS diode operates as a unidirectional clamping device with a specified breakdown voltage range of 7.78–8.60 V at 10 mA test current and a maximum stand-off voltage of 7.0 V. Its low incremental surge resistance and fast response time enable effective suppression of ESD and load-dump transients without affecting normal circuit operation.
Thermal performance is defined by RθJA = 85–100 °C/W (FR4, 2 oz copper) and RθJM = 2.5–3.0 °C/W, supporting reliable operation up to TJ = 150 °C. The cathode-band-marked SMPC package allows automated placement while maintaining strict polarity alignment for correct anode-cathode orientation in series-connected protection paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 μs) | 1500 W - sustains high-energy transients without failure in automotive load-dump events |
| Breakdown Voltage VBR | 7.78–8.60 V @ 10 mA - ensures precise triggering above nominal 7.0 V rail without false conduction |
| Clamping Voltage VC | ≤12.0 V @ 200 A - limits downstream IC voltage stress during worst-case surge conditions |
| Stand-off Voltage VWM | 7.0 V - matches common 7 V auxiliary supply rails in automotive body control modules |
| Maximum Leakage IR | 1500 μA @ VWM - negligible standby current impact on low-power sensor circuits |
| Operating Temperature | -55 to +150 °C - qualified for under-hood and industrial ambient environments |
| Package | SMPC (TO-277A) - 3-terminal SMD footprint with 0.189" × 0.134" body and 1.1 mm height |
Pinout & Package
SMPC7.0A-M3/86A uses 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. Mounting requires polarity-aware placement per JEDEC TO-277A outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 & Anode 2 | Common anode connection | Internally tied terminals-must be connected to same potential (e.g., ground or low-side return path) |
| Cathode | Transient clamping output | Connected to protected line (e.g., 7 V supply); conducts only when VIN > VBR |
Key Features
| Feature | Design Value |
|---|---|
| Very low profile (1.1 mm height) | Enables use in ultra-thin modules such as automotive camera ECUs and portable diagnostic tools |
| MSL Level 1 (260 °C peak) | Supports standard lead-free reflow without moisture sensitivity concerns or baking requirements |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (<1 ns rise time), improving protection margin |
| AEC-Q101 comparable qualification | Meets automotive reliability standards for temperature cycling, HTRB, and ESD-though base M3 suffix is industrial grade |
| Halogen-free & RoHS-compliant | Fulfills environmental compliance for global OEM BOMs without requiring material exception waivers |
Applications
| Automotive Body Control Module | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Protecting 7 V supply rail feeding LIN transceivers and door-lock actuators against battery load-dump spikes. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between fused input and LDO regulator input.

Use Scenario: Safeguarding analog front-end inputs of 4–20 mA loop-powered pressure sensors exposed to field wiring surges. IC Role / Device Role / Timing Role: Standoff-clamp TVS connected across sensor supply pins to shunt induced transients before they reach precision op-amps. Use Value: Maintains signal integrity by clamping surges within 1 ns, avoiding ADC saturation or offset drift caused by rail excursions beyond 7.0 V. |
| Consumer Appliance Motor Driver | Telecom Power Interface |
Use Scenario: Shielding microcontroller I/O lines driving brushed DC motors in smart HVAC blowers from back-EMF spikes. IC Role / Device Role / Timing Role: Low-capacitance TVS mounted directly at motor driver IC pins to suppress inductive kickback. Use Value: Prevents latch-up or permanent gate oxide damage in MOSFET drivers by clamping spikes to ≤12.0 V before propagation into logic-level circuitry. |
Use Scenario: Protecting PoE-powered Ethernet switch port regulators from lightning-induced surges on DC input lines. IC Role / Device Role / Timing Role: Primary-stage TVS on 7 V auxiliary rail supplying PHY management circuitry. Use Value: Absorbs 1500 W pulses without degradation, preserving power integrity during Category 4 surge tests (IEC 61000-4-5). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.0A-E3/61 | DO-214AC package; 1.5 kW PPPM; VC = 12.0 V @ 171 A; higher RθJA (140 °C/W) | Larger footprint (4.5 × 2.7 mm vs. 4.8 × 3.4 mm); less suitable for ultra-dense layouts | Select when legacy DO-214AC board space exists and thermal margin permits higher junction rise |
| SMCJ7.0AHE3/73 | SMC (DO-214AB) package; 1500 W PPPM; VC = 12.0 V @ 200 A; AEC-Q101 qualified | Requires larger PCB area (7.1 × 6.2 mm); rated for automotive-grade production without qualification upgrade | Choose for new automotive designs requiring full AEC-Q101 certification and higher surge endurance cycles |
Compared with SMAJ7.0A-E3/61 and SMCJ7.0AHE3/73, SMPC7.0A-M3/86A offers the smallest height (1.1 mm) and tightest board area among 7 V unidirectional TVS diodes, making it optimal for next-generation compact modules where vertical clearance and layout density are critical constraints.

FAQ
What is the exact breakdown voltage range for SMPC7.0A-M3/86A?
The SMPC7.0A-M3/86A has a guaranteed breakdown voltage (VBR) range of 7.78 V to 8.60 V at 10 mA test current, measured per ANSI/IEEE C62.35. This ensures reliable turn-on above the 7.0 V stand-off voltage while avoiding premature conduction during normal operation of 7 V rails.
Does SMPC7.0A-M3/86A meet AEC-Q101 qualification?
No-SMPC7.0A-M3/86A carries the industrial-grade M3 suffix and is not AEC-Q101 qualified. For automotive-qualified equivalents, consider SMPC22ANHM3/H or SMCJ7.0AHE3/73, which carry the HM3 suffix and full AEC-Q101 certification per Vishay's ordering matrix.
What does the /86A package code indicate for SMPC7.0A-M3/86A?
The /86A suffix denotes a 7-inch plastic tape-and-reel packaging format containing 1500 units per reel, optimized for high-speed pick-and-place machines. It specifies the carrier tape width, sprocket hole pitch, and component orientation-not electrical or thermal differences from other SMPC7.0A-M3 variants.
How is polarity identified on SMPC7.0A-M3/86A?
SMPC7.0A-M3/86A uses a cathode band marking aligned with the cathode terminal, per JEDEC TO-277A mechanical drawing. The band must face the protected line (e.g., 7 V rail); Anode 1 and Anode 2 are internally shorted and connect to ground or reference potential.
Can SMPC7.0A-M3/86A be used in bidirectional configurations?
No-SMPC7.0A-M3/86A is strictly unidirectional. Bidirectional operation requires pairing two devices or selecting a dedicated bidirectional variant like SMPC7.0CA-M3/86A. Using SMPC7.0A-M3/86A in reverse-biased mode exceeds its maximum reverse leakage specification and risks thermal runaway.
