Schottky Rectifier, 2 x 15 A
FEATURES
• 150 °C TJ operation
• Low forward voltage drop
• High frequency operation
• High purity, high temperature epoxy
encapsulation for enhanced mechanical strength
and moisture resistance
• Guard ring for enhanced ruggedness and long
term reliability
• Compliant to RoHS Directive 2002/95/EC
• Designed and qualified according to JEDEC-JESD47
• Halogen-free according to IEC 61249-2-21 definition
(-N3 only)
DESCRIPTION
The VS-25CTQ... center tap Schottky rectifier 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,
converters, freewheeling diodes, and reverse battery
protection.
