Product details
Overview
SMPC11A-M3/86A from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor in SMPC (TO-277A) package, with 11.0 V stand-off voltage (VWM), 12.2–13.5 V breakdown voltage (VBR), and 1500 W peak pulse power (PPPM) at 10/1000 μs. It clamps transients to ≤18.2 V at 82.4 A IPPM and operates from −55 °C to +150 °C - deployed for protecting MOSFETs and ICs against inductive switching surges in automotive and industrial control circuits.
For engineers reviewing the SMPC11A-M3/86A datasheet, SMPC11A-M3/86A pinout, SMPC11A-M3/86A application, or SMPC11A-M3/86A equivalent, key selection criteria include unidirectional polarity, 1.25 W steady-state power dissipation, MSL Level 1 moisture sensitivity, halogen-free RoHS-compliant construction, and compatibility with automated SMT placement on FR4 PCBs.
Technical Context
This device functions as a silicon avalanche diode optimized for fast-response transient suppression. Its low incremental surge resistance and sub-nanosecond response time enable effective clamping of ESD and load-switching spikes before downstream components are damaged. The dual-anode configuration (SMPCxxA series) routes surge current symmetrically across two anode terminals to the shared cathode, reducing localized thermal stress during high-peak events.
Thermal performance is defined per JEDEC 51-2A (RθJA = 85–100 °C/W) and JEDEC 51-14 (RθJM = 2.5–3.0 °C/W), confirming suitability for thermally constrained layouts. The 1.1 mm profile and matte tin-plated leads meet J-STD-002 solderability and JESD22-B102 reliability standards, supporting reflow profiles up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 11.0 V - maximum continuous reverse operating voltage before significant leakage; defines safe working margin below breakdown. |
| VBR @ IT = 1 mA | 12.2–13.5 V - guaranteed avalanche initiation range; ensures predictable turn-on under transient conditions. |
| VC @ IPPM | ≤18.2 V - clamped voltage at 82.4 A peak pulse; determines maximum stress imposed on protected circuitry. |
| PPPM (10/1000 μs) | 1500 W - peak transient energy handling capacity; enables protection against severe inductive kickback events. |
| PD @ TA = 25 °C | 1.25 W - steady-state power limit; sets thermal derating baseline for continuous leakage or repetitive surges. |
| TJ max. | +150 °C - maximum junction temperature; supports operation in under-hood automotive and industrial environments. |
| Package | SMPC (TO-277A) - 3-terminal surface-mount outline with 0.173–0.189″ body width; optimized for high-current routing and thermal relief. |
Pinout & Package
SMPC11A-M3/86A uses the SMPC (TO-277A) package: a 3-terminal, unidirectional SMD device with cathode denoted by a band. Terminals are matte tin-plated for solderability per J-STD-002 and JESD22-B102, and meet JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 | Primary surge current input path | Connected in parallel with Anode 2 to distribute high-peak transient current and reduce localized heating. |
| Anode 2 | Secondary surge current input path | Shares surge conduction with Anode 1; enables symmetrical current splitting and improved thermal balance. |
| Cathode (banded end) | Common output / reference node | Connected to system ground or common return; clamping action occurs between cathode and either anode. |
Key Features
| Feature | Design Value |
|---|---|
| Very low profile (1.1 mm typical height) | Enables integration into space-constrained PCBs without interfering with adjacent tall components or enclosures. |
| Unidirectional polarity | Protects DC-biased lines only - prevents false triggering on AC or bidirectional signal paths. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients, improving clamping precision and downstream component safety. |
| MSL Level 1 (260 °C peak) | Supports standard lead-free reflow without baking or special handling, reducing manufacturing complexity and cost. |
| Halogen-free, RoHS-compliant, industrial grade | Meets environmental compliance requirements for global commercial and industrial deployments without material restrictions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A-E3/5A (Vishay) | SMA package (DO-214AC), lower PPPM (400 W), higher RθJA (~110 °C/W), single-anode topology | Limited to lower-energy transients; unsuitable for 1500 W surge environments or high-density thermal layouts | Select when board space allows larger footprint and surge energy is ≤400 W; not drop-in for SMPC11A-M3/86A's dual-anode current sharing. |
| 1.5KE11A (ON Semiconductor) | Through-hole DO-201 package, 1500 W PPPM, but 2.5 mm height, no MSL Level 1 rating, leaded construction | Requires wave soldering or hand assembly; incompatible with fully automated SMT lines and high-reliability reflow processes | Choose only for legacy through-hole designs or prototyping where reflow compatibility and 1.1 mm profile are non-critical. |
Compared with SMAJ11A-E3/5A and 1.5KE11A, SMPC11A-M3/86A delivers identical 11 V standoff and 1500 W surge capability in a low-profile, MSL Level 1–qualified SMT package with dual-anode current sharing - making it uniquely suited for high-volume automotive and industrial PCBs requiring automated assembly and thermal resilience.

FAQ
What is the polarity configuration of SMPC11A-M3/86A?
SMPC11A-M3/86A is a unidirectional transient voltage suppressor. Its cathode is marked by a band on the package body, with two anode terminals (Anode 1 and Anode 2) electrically isolated from each other and tied to the same potential during clamping. This configuration allows symmetric current division during high-peak transients, reducing thermal stress versus single-anode alternatives. The device must be oriented with the banded end toward the system ground or reference node to function correctly.
Does SMPC11A-M3/86A meet automotive qualification standards?
SMPC11A-M3/86A is rated for industrial-grade operation and is halogen-free, RoHS-compliant, and MSL Level 1 qualified. While the base SMPCxxA series (including SMPC11A-M3/86A) is not AEC-Q101 qualified, Vishay offers the SMPCxxAN variant (e.g., SMPC22AN) with AEC-Q101 certification. For automotive applications requiring formal qualification, SMPC11A-M3/86A may be used in non-safety-critical subsystems, but designers should verify compliance with specific OEM requirements before deployment.
What is the maximum clamping voltage of SMPC11A-M3/86A at its rated peak pulse current?
The maximum clamping voltage (VC) of SMPC11A-M3/86A is 18.2 V when subjected to its rated peak pulse current (IPPM) of 82.4 A under the standard 10/1000 μs waveform. This value is measured with the cathode mounted on a heatsink per the datasheet test condition, and represents the upper bound of voltage seen by protected circuitry during worst-case transient events - critical for ensuring downstream components remain within their absolute maximum voltage ratings.
Can SMPC11A-M3/86A be used in bidirectional signal line protection?
No - SMPC11A-M3/86A is strictly unidirectional and must be used only on DC-biased or polarity-defined lines. Applying reverse bias beyond its 11.0 V stand-off voltage (VWM) will cause premature conduction and potential failure. For bidirectional protection (e.g., RS-485, USB, or AC-coupled signals), a pair of SMPC11A-M3/86A devices in opposing orientation or a dedicated bidirectional TVS such as SMPC11CA would be required. Using SMPC11A-M3/86A on bidirectional lines violates its specified operating mode and voids performance guarantees.
What is the thermal resistance specification for SMPC11A-M3/86A?
SMPC11A-M3/86A 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. Its junction-to-mount thermal resistance (RθJM) is 2.5 °C/W typical and 3.0 °C/W maximum, measured using JEDEC 51-14 TDIM methodology. These values confirm its suitability for thermally dense layouts where heat must be efficiently conducted from the die to the PCB plane or heatsink.
