Characteristics 151CNQ... Units The 151CNQ... non-isolated, center tap Schottky rectifier
module series has been optimized 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 module
Multiple leads per terminal for high frequency, high current
PC board mounting
High purity, high temperature epoxy encapsulation for
enhanced mechanical strength and moisture resistance
Very low forward voltage drop
High frequency operation
Guard ring for enhanced ruggedness and long term
reliability
Low profile, high current package
