MBR2045CTG Description

Short technical summary and product information.

The MBR2045CTG is a dual Schottky barrier rectifier from On Semiconductor featuring a common cathode configuration. It is rated for a peak repetitive reverse voltage of 45V and delivers up to 20A of total average rectified forward current, or 10A per diode leg. The device offers low forward voltage drop (0.57V max at 10A, 125°C) and high surge capability (150A non-repetitive peak). Operating over a junction temperature range of -65°C to 175°C, it is well suited for high-efficiency power rectification in switch-mode power supplies, power management systems, and instrumentation. The part is housed in a through-hole TO-220AB (TO-220-3) package with epoxy molding meeting UL 94 V-0 flammability rating. It is Pb-free and RoHS compliant. ESD rating: Human Body Model 3B, Machine Model C. Thermal resistance is 2.0°C/W junction-to-case.
