MBR2045EMFST3G Description

Short technical summary and product information.

The MBR2045EMFST3G from onsemi is a state-of-the-art Schottky barrier rectifier designed for high-efficiency power conversion. It features a maximum peak repetitive reverse voltage of 45V and an average rectified forward current of 20A at a case temperature of 130°C. The device exhibits a low typical forward voltage of 640 mV at 20A, contributing to reduced power loss.

 

This rectifier is housed in a compact 5-DFN (SO-8FL) surface mount package, also designated as 8-PowerTDFN with 5 leads. The package supports board mounting inspection and probing, and features wettable flanks. The lead finish is 100% matte tin (Sn), and the device meets MSL 1 (unlimited) moisture sensitivity requirements.

 

The part offers high surge capability with a non-repetitive peak surge current rating of 400A (60 Hz half-wave). It operates over a junction temperature range of -55°C to 150°C. The MBR2045EMFST3G is Pb-free and halide-free, and suitable for applications such as output rectification in compact portable consumer electronics and freewheeling diodes in inductive loads.
