Product details
Overview
SMPC16A-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 and ESD events on power and signal lines. It features a breakdown voltage of 17.8–19.7 V, stand-off voltage of 16.0 V, peak pulse power of 1500 W (10/1000 μs), clamping voltage of 26.0 V at 57.7 A, and operates within -55 °C to +150 °C junction temperature range.
For engineers reviewing the SMPC16A-M3/86A datasheet, SMPC16A-M3/86A pinout, SMPC16A-M3/86A application, or SMPC16A-M3/86A equivalent, key selection criteria include unidirectional polarity, TO-277A (SMPC) package compatibility, 1.25 W steady-state power dissipation, MSL Level 1 reflow capability, and AEC-Q101 qualification status (not applicable to this industrial-grade variant).
Technical Context
This TVS diode uses a planar silicon junction structure optimized for fast response (<1 ns) and low incremental surge resistance, enabling effective suppression of transient overvoltages induced by inductive load switching or lightning surges. Its unidirectional configuration provides forward conduction path only during reverse-biased overvoltage events.
The device is rated for 1500 W peak pulse power under standardized 10/1000 μs waveform conditions and exhibits a maximum clamping voltage of 26.0 V at 57.7 A IPPM - critical for protecting downstream MOSFETs, ICs, and sensor interfaces without exceeding safe voltage thresholds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 17.8–19.7 V at 1.0 mA test current - defines minimum voltage at which clamping initiates reliably |
| Stand-off Voltage (VWM) | 16.0 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 μA |
| Peak Pulse Power (PPPM) | 1500 W (10/1000 μs) - determines transient energy handling capacity on PCB traces |
| Clamping Voltage (VC) | 26.0 V at 57.7 A IPPM - limits maximum voltage seen by protected circuit during surge |
| Junction Temperature Range | -55 °C to +150 °C - supports operation in automotive under-hood and industrial control environments |
| Package | SMPC (TO-277A) - ultra-low profile (1.1 mm typical height), halogen-free, RoHS-compliant, MSL Level 1 |
| Thermal Resistance (RθJA) | 85–100 °C/W - defines thermal derating behavior when mounted on FR4 with 2 oz copper |
Pinout & Package

FAQ
What is the polarity configuration of SMPC16A-M3/86A?
SMPC16A-M3/86A is a unidirectional transient voltage suppressor. Its cathode is marked by a band on the package body and must be connected to the line being protected, while both anode terminals connect to the reference (e.g., ground). This configuration allows forward conduction only during reverse overvoltage events, ensuring no DC path during normal operation.
Does SMPC16A-M3/86A meet AEC-Q101 qualification?
No, SMPC16A-M3/86A is an industrial-grade variant with M3 suffix. AEC-Q101 qualification applies only to HM3-suffixed parts (e.g., SMPC22ANHM3), which are designated for automotive use. SMPC16A-M3/86A carries halogen-free, RoHS-compliant, and MSL Level 1 reflow ratings but lacks automotive qualification documentation.
What is the meaning of the /86A package code in SMPC16A-M3/86A?
The /86A suffix denotes the tape-and-reel packaging option: 7-inch diameter plastic tape and reel, with a base quantity of 1500 units per reel. This format is optimized for high-speed pick-and-place assembly and aligns with industry-standard SMT handling protocols for the SMPC (TO-277A) package.
How does the dual-anode configuration of SMPC16A-M3/86A affect PCB layout?
The dual-anode (Anode 1 and Anode 2) terminals of SMPC16A-M3/86A are internally shorted and must be connected to the same net - typically ground or power return. Layout requires symmetric, low-inductance routing to both anode pads to ensure balanced current sharing during surge events and avoid localized heating or voltage imbalance.
What is the maximum clamping voltage of SMPC16A-M3/86A under surge conditions?
The maximum clamping voltage (VC) of SMPC16A-M3/86A is 26.0 V when subjected to its rated peak pulse current of 57.7 A (10/1000 μs waveform). This value is measured at the device terminals and represents the upper voltage limit imposed on the protected circuit during worst-case transient events.
