SBR4045CTFP

Diode Arrays Overview

The SBR4045CTFP is a dual common cathode Super Barrier Rectifier manufactured by Diodes Incorporated. It utilizes patented SBR technology to deliver low forward voltage drop and excellent high-temperature stability. The device features soft, fast switching capability and operates within an ambient temperature range of -65°C to +150°C. It is housed in an ITO-220AB (ITO-220FP-3) through-hole package with a matte tin finish on copper leadframes. Key electrical ratings include a 45V peak repetitive reverse voltage and a total average rectified output current of 40A (20A per leg).
