2 x 10 A
80 to 100 V
FEATURES
• 150 °C TJ operation
• Center tap D2PAK and TO-262 packages
• Low forward voltage drop
• High purity, high temperature epoxy encapsulation for
enhanced mechanical strength and moisture resistance
• High frequency operation
• Guard ring enhanced ruggedness and long term reliability
• Designed and qualified for AEC Q101 level
DESCRIPTION
This center tap Schottky rectifier has been optimized for low
reverse leakage at high temperature. 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.
