Onsemi MBRF20200CTG Schottky Rectifier: Features and Application Overview

The Onsemi MBRF20200CTG is a high-performance Schottky rectifier designed for modern power conversion applications where efficiency, thermal performance, and reliability are critical. This device features a dual-center tap configuration housed in a TO-220AB package, making it suitable for high-current and high-frequency operations.

A key attribute of this Schottky rectifier is its ultra-low forward voltage drop, typically around 0.55V at 100A. This characteristic significantly reduces conduction losses, leading to improved system efficiency and reduced heat generation. Additionally, the Schottky barrier technology enables extremely fast switching performance, minimizing reverse recovery time and associated losses. This makes the MBRF20200CTG ideal for high-frequency SMPS, inverters, and switching regulators.

The rectifier offers a high average forward current rating of 100A per leg and a repetitive reverse voltage of 200V, providing robust performance in demanding environments. Its excellent thermal characteristics, supported by a low thermal resistance junction-to-case, allow for effective heat dissipation. This is further enhanced when used with a heatsink, enabling stable operation under continuous high-load conditions.

Typical applications include:

- Switch-mode power supplies (SMPS)

- DC-DC converters

- Freewheeling diodes

- Reverse polarity protection

- Motor drive circuits

- Solar inverters and energy storage systems
