Schottky Barrier Diode
These Schottky barrier diodes are designed for high-speed
switching applications, circuit protection, and voltage clamping.
Extremely low forward voltage reduces conduction loss. Miniature
surface mount package is excellent for hand-held and portable
applications where space is limited.
Features
•Extremely Fast Switching Speed
•Extremely Low Forward Voltage - 0.28 V (Typ) @ IF = 1.0 mAdc
•Low Reverse Current
•Lead-Free Plating
•Pb-Free Package is Available
MAXIMUM RATINGS
Rating Symbol Value Unit
Peak Reverse Voltage VRM 40 V
Reverse Voltage VR30 V
Forward Continuous Current (DC) IF30 mA
Peak Forward Surge Current IFSM 500 mA
ESD Rating: Class 1C per Human Body Model
Class A per Machine Model
Stresses exceeding Maximum Ratings may damage the device. Maximum
Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. Extended exposure to stresses above the
Recommended Operating Conditions may affect device reliability.
