Schottky Rectifier, 3 A
MBR340
Vishay High Power Products
FEATURES
• Low profile, axial leaded outline
• Very 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
• Lead (Pb)-free plating
• Designed and qualified for industrial level
DESCRIPTION
The MBR340 axial leaded Schottky rectifier has been
optimized for very low forward voltage drop, with moderate
leakage. Typical applications are in switching power
supplies, converters, freewheeling diodes, and reverse
battery protection.

(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 = 80 % rated VR
