TJrange - 55 to 150 °C
Characteristics 150CMQ... Units The 150CMQ 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
Isolated heatsink
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
