2 x 15 A
80/100 V
FEATURES
• 175 °C TJ operation
• Center tap configuration
• 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
• Designed and qualified for industrial level
DESCRIPTION
The center tap Schottky rectifier series has been optimized
for 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, freewheeling diodes, and
reverse battery protection.

Note
(1) Formula used: TC = TJ - (Pd + PdREV) x RthJC;
Pd = Forward power loss = IF(AV) x VFM at (IF(AV)/D) (see fig. 6);
PdREV = Inverse power loss = VR1 x IR (1 - D); IR at VR1 = 10 V
