Characteristics 150CNQ... Units The 150CNQ... non-isolated, center tap Schottky rectifier
module series has been optimized for very low forward voltage
drop, with moderate leakage. The proprietary barrier technology
allows for reliable operation up to 150° C junction temperature.
Typical applications are in switching power supplies, convert-
ers, free-wheeling diodes, and reverse battery protection.
150° 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
