20CTQ045 Description

Short technical summary and product information.

The SMC Diode Solutions 20CTQ045 is a Schottky rectifier array featuring a 1 pair common cathode configuration. Designed for high-frequency operation and high-temperature environments, it delivers an average rectified forward current of 20A per device (10A per leg) and a peak repetitive reverse voltage of 45V.

 

Electrical characteristics include a maximum forward voltage of 0.8V at 20A and a typical forward voltage of 0.75V at 20A. Maximum reverse current is 1mA at 45V, with a typical value of 0.03mA. The device is rated for operation from -55°C to +150°C junction temperature. A guard ring enhances ruggedness and long-term reliability.

 

Packaged in a through-hole TO-220AB (TO-220-3) case, the 20CTQ045 is suitable for switching power supplies, converters, free-wheeling diodes, and reverse battery protection. The terminals are 100% pure tin finish, and the device is lead-free (Pb-Free).
