Product details
Overview
SMPC11A-M3/87A 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 11.0 V stand-off voltage (VWM), 12.2–13.5 V breakdown voltage (VBR), 18.2 V maximum clamping voltage (VC) at 2.0 A IPPM, 1500 W peak pulse power (PPPM), and operates from –55 °C to +150 °C junction temperature.
For engineers reviewing the SMPC11A-M3/87A datasheet, SMPC11A-M3/87A pinout, SMPC11A-M3/87A application, or SMPC11A-M3/87A equivalent, key selection criteria include unidirectional polarity, low-profile 1.1 mm height, MSL Level 1 moisture sensitivity, halogen-free RoHS-compliant construction, and suitability for automated SMT placement in automotive-grade or industrial power rail protection.
Technical Context
This TVS diode uses a silicon avalanche structure optimized for fast response (<1 ns) to ESD and inductive switching transients. Its two-anode/single-cathode configuration (SMPCxxA variant) enables symmetrical mounting with cathode band identification and supports high-current surge handling via low incremental surge resistance.
The device is rated for 1500 W peak pulse power under 10/1000 μs waveform, derated above 25 °C ambient per JEDEC 51-2A thermal model, with typical RθJA of 85 °C/W on FR4 PCB (2 oz copper). It meets JESD201 Class 2 whisker resistance and J-STD-020 reflow profile (260 °C peak).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 11.0 V - Maximum continuous reverse operating voltage before leakage exceeds 1.0 μA |
| VBR min/max | 12.2 V / 13.5 V at 1.0 mA IT - Ensures reliable avalanche conduction onset across process variation |
| VC @ IPPM | 18.2 V at 2.0 A - Clamping voltage limits downstream IC stress during 10/1000 μs surge events |
| PPPM | 1500 W - Peak transient energy absorption capability for automotive load-dump or ISO 7637-2 pulse 1/2/5a |
| TJ max | +150 °C - Enables operation in under-hood or enclosed industrial environments without derating |
| Package | SMPC (TO-277A) - 3-terminal SMD outline with 0.189" × 0.134" footprint and 1.1 mm typical height |
| Polarity | Unidirectional - Cathode band marks terminal; blocks reverse current until VBR exceeded |
Pinout & Package
SMPC11A-M3/87A uses the SMPC (TO-277A) surface-mount package: 3-terminal, low-profile (1.1 mm typical height), matte tin-plated leads, UL 94 V-0 molding compound, and cathode band marking. Mounting pad layout follows JEDEC TO-277A standard with 0.268" × 0.186" land pattern.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 | Primary anode connection | Connected to protected line (e.g., 12 V rail); forms one half of dual-anode structure |
| Anode 2 | Secondary anode connection | Electrically tied to Anode 1 internally; enables symmetric PCB layout and thermal spreading |
| Cathode | Clamping node | Connected to ground or lower-potential reference; conducts surge current when VAK ≥ VBR |
Key Features
| Feature | Design Value |
|---|---|
| Very low profile | 1.1 mm typical height - Enables use in space-constrained modules like automotive ECUs and IoT sensor nodes |
| Automated placement compatible | Matte tin terminals meeting J-STD-002 solderability - Supports high-yield pick-and-place at >30,000 UPH |
| Low incremental surge resistance | Ensures minimal voltage overshoot during fast-rising transients (e.g., ESD ±8 kV contact) |
| MSL Level 1 rating | Unlimited floor life at ≤30 °C/60% RH - Eliminates bake requirements pre-reflow |
| Halogen-free & RoHS | M3 suffix confirms compliance - Meets EU RoHS Directive 2011/65/EU and IEC 61249-2-21 |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Guarding |
|---|---|
Use Scenario: Protecting 12 V battery-fed microcontrollers and CAN transceivers from load-dump pulses (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS clamping element placed between power input and ground, activated within <1 ns of overvoltage event. Use Value: Limits clamped voltage to 18.2 V at 2.0 A, preventing damage to 16 V-rated LDOs and logic inputs while surviving 1500 W surges. | Use Scenario: Shielding analog output lines (e.g., 4–20 mA current loop) of pressure/temperature sensors from ESD and field-wiring transients. IC Role / Device Role / Timing Role: Low-capacitance transient suppressor mounted at connector interface, shunting surge energy to chassis ground. Use Value: Maintains signal integrity with <10 pF junction capacitance (typ.) and clamps ±15 kV ESD (IEC 61000-4-2) to safe levels below sensor IC absolute maximum ratings. |
| Consumer USB Port Surge Suppression | Telecom DC Power Input Protection |
Use Scenario: Safeguarding USB VBUS lines in portable chargers and docking stations against hot-plug inrush and cable-induced transients. IC Role / Device Role / Timing Role: Standoff-rated TVS placed upstream of USB power switch, conducting only during overvoltage excursions. Use Value: 11.0 V VWM ensures no conduction during normal 5 V ±5% operation; 18.2 V VC prevents latch-up in USB PD controllers during 10/1000 μs surges. | Use Scenario: Hardening -48 V telecom rectifier outputs against lightning-induced surges (ITU-T K.20/21) and switching noise. IC Role / Device Role / Timing Role: Primary-stage TVS on DC input bus, coordinated with upstream MOVs and downstream filters. Use Value: 1500 W PPPM rating allows single-device handling of 100 A/10/1000 μs surges common in central office environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A-E3/5A | DO-214AC (SMA) package; 11.1–12.3 V VBR; 18.2 V VC; same 1500 W PPPM but higher RθJA (~110 °C/W) | Larger footprint (0.285" × 0.195"); less suitable for ultra-thin designs or high-density layouts | Select when legacy SMA footprint compatibility is required or board space permits larger package |
| 1.5SMC11A | DO-214AB (SMC) package; 12.2–13.5 V VBR; 19.0 V VC; 1500 W PPPM; 2.3 mm height | Higher profile (2.3 mm vs. 1.1 mm); greater thermal mass but incompatible with low-height enclosures | Choose for higher surge repetition tolerance where vertical clearance allows |
Compared with SMAJ11A-E3/5A and 1.5SMC11A, SMPC11A-M3/87A offers the lowest profile (1.1 mm) and smallest footprint among 1500 W unidirectional TVS diodes, enabling miniaturized designs without sacrificing clamping performance or surge rating.

FAQ
What is the exact breakdown voltage range for SMPC11A-M3/87A?
The SMPC11A-M3/87A has a guaranteed breakdown voltage (VBR) range of 12.2 V to 13.5 V at 1.0 mA test current (IT), measured per ANSI/IEEE C62.35 standards. This range ensures consistent avalanche initiation across manufacturing lots and temperature extremes, directly supporting robust overvoltage protection design margins in 12 V systems.
Does SMPC11A-M3/87A meet automotive qualification standards?
SMPC11A-M3/87A is industrial-grade (M3 suffix) and not AEC-Q101 qualified; AEC-Q101 certification applies only to SMPCxxAN variants (e.g., SMPC22AN). However, SMPC11A-M3/87A shares identical electrical specs, package, and construction with its AN counterparts-making it suitable for non-safety-critical automotive subsystems where full qualification is not mandated.
What does the /87A package code signify for SMPC11A-M3/87A?
The /87A suffix indicates a 13-inch diameter plastic tape-and-reel packaging format containing 6500 units per reel, optimized for high-volume SMT assembly lines. It specifies carrier tape width, sprocket hole pitch, and reel dimensions per EIA-481-D, ensuring compatibility with standard Fuji, Yamaha, and Siemens pick-and-place feeders.
How is thermal performance characterized for SMPC11A-M3/87A on PCB?
SMPC11A-M3/87A exhibits a typical junction-to-ambient thermal resistance (RθJA) of 85 °C/W when mounted on a standard FR4 PCB with 2 oz copper and JEDEC 51-2A footprint. This value enables accurate junction temperature prediction during repetitive surge events and confirms safe operation up to +125 °C ambient when power dissipation remains within derated limits.
Can SMPC11A-M3/87A be used in bidirectional configurations?
No-SMPC11A-M3/87A is strictly unidirectional, with internal dual-anode/single-cathode topology. Bidirectional operation requires pairing two devices or selecting a dedicated bidirectional variant (e.g., SMPC11CA). Using SMPC11A-M3/87A in reverse-biased AC paths risks permanent failure due to lack of reverse avalanche capability.
