20 Amp 45V Schottky Rectifier Diode 20CTQ045PBF With TO-220 Package
FEATURES
The 20CTQ center tap Schottky rectifier series has been optimized for low reverse leakage at high
temperature. The proprietary barrier technology allows for reliable operation up to 175°C
junction temperature. Typical applications are in switching power supplies, converters,
free-wheeling diodes and reverse battery protection.
* 175° C TJ operation
* Center tap TO-220 package
* Low forward voltage drop
* High purity, high temperature epoxy encapsulation for enhanced mechanical strength and
moisture resistance
* High frequency operation
* Guard ring for enhanced ruggedness and long term reliability
