Product Description
Product Overview
The US1A thru US1M series are surface mount high-efficiency rectifiers designed for high-frequency rectification and freewheeling applications. They feature a low-profile package ideal for automated placement, glass-passivated chip junctions, super-fast reverse recovery times, low switching losses, high efficiency, and high forward surge capability. These rectifiers are suitable for use in switching mode converters and inverters for consumer, computer, automotive, and telecommunication applications.
