Product details
Overview
SMPC16A-M3/87A from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor in the SMPC (TO-277A) package, rated for 16.0 V stand-off voltage (VWM), 17.8–19.7 V breakdown voltage (VBR), and 1500 W peak pulse power (PPPM) with 26.0 V clamping voltage (VC) at 57.7 A IPPM. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients in industrial and automotive electronics.
For engineers reviewing the SMPC16A-M3/87A datasheet, SMPC16A-M3/87A pinout, SMPC16A-M3/87A application, or SMPC16A-M3/87A equivalent, key selection criteria include unidirectional polarity, 1.1 mm profile height, MSL Level 1 moisture sensitivity, 150 °C max junction temperature, and AEC-Q101 qualification eligibility via HM3 suffix variants.
Technical Context
This device operates as a silicon 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 10/1000 μs waveform surges up to 1500 W without thermal runaway under defined PCB mounting conditions.
The SMPC16A-M3/87A uses a dual-anode, single-cathode configuration (Anode 1 / Anode 2 / Cathode) in the SMPC (TO-277A) package, where the cathode band denotes polarity. Thermal performance is specified with RθJA ≤ 100 °C/W on FR4 with 2 oz copper, supporting reliable operation across -55 °C to +150 °C junction temperature range.
Key Specifications

FAQ
What is the maximum clamping voltage of the SMPC16A-M3/87A during a 10/1000 μs surge event?
The SMPC16A-M3/87A has a maximum clamping voltage (VC) of 26.0 V at 57.7 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value is measured with the cathode mounted on heatsink per datasheet test setup, ensuring consistent protection margin for 16 V nominal circuits. The SMPC16A-M3/87A maintains this clamping performance across its specified operating temperature range.
Is the SMPC16A-M3/87A AEC-Q101 qualified?
The SMPC16A-M3/87A is an industrial-grade variant with M3 suffix and is not AEC-Q101 qualified. However, Vishay offers the SMPC16ANHM3/87A as the AEC-Q101 qualified counterpart in the same SMPC package. The SMPC16A-M3/87A meets all electrical and mechanical specifications for industrial applications and shares identical pinout, thermal profile, and surge ratings with its automotive-grade sibling.
What does the /87A package code indicate for SMPC16A-M3/87A?
The /87A suffix indicates a 13-inch diameter plastic tape-and-reel packaging format containing 6500 units per reel. This delivery mode supports high-volume automated assembly and is compatible with standard pick-and-place equipment. The /87A code does not affect electrical or thermal characteristics - it is purely a packaging and logistics designation for the SMPC16A-M3/87A device.
How does the dual-anode configuration of SMPC16A-M3/87A improve surge handling?
The SMPC16A-M3/87A features two anode terminals electrically in parallel, enabling symmetrical current division during bidirectional surge events on a single-line interface. This dual-anode architecture reduces localized heating and improves reliability under repeated transients compared to single-anode TVS diodes. In practice, the SMPC16A-M3/87A sustains its 1500 W PPPM rating with more uniform thermal distribution across the die.
Can SMPC16A-M3/87A be used in place of a bidirectional TVS for AC line protection?
No - the SMPC16A-M3/87A is strictly unidirectional and must be used only in DC applications with correctly oriented polarity. It lacks reverse-breakdown capability and will not suppress negative-going transients. For AC or bidirectional protection, a dedicated bidirectional part such as SMPC16CA-M3/87A (if available) or separate back-to-back unidirectional devices are required. The SMPC16A-M3/87A functions exclusively as a cathode-to-ground clamp.
