Overview

The MSS1P3-M3/89A is a high-efficiency Schottky barrier rectifier in a low-profile MicroSMP (DO-219AD) package. It is designed for high-frequency rectification and freewheeling applications, supporting an average forward current of 1A with a maximum reverse voltage of 30V.

Why Choose This Part

The component features a low forward voltage drop of 550 mV at 1A, which minimizes power losses and improves system efficiency. Its ultra-compact MicroSMP package has a height of only 0.65mm, making it ideal for space-constrained PCB layouts, and it is AEC-Q101 qualified for automotive reliability.

Applications

DC/DC Converters
Used as a secondary rectifier in compact power supply modules to improve efficiency.
Polarity Protection
Protects sensitive downstream circuitry from battery reversal or incorrect power input.
Freewheeling Diode
Suppresses inductive voltage spikes in motor control and relay driver circuits.
High-Frequency Inverters
Handles low-voltage rectification in high-speed switching power stages.
