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.
•Extremely Fast Switching Speed
•Extremely Low Forward Voltage − 0.28 V (Typ) @ IF = 1.0 mAdc
•Low Reverse Current
•Lead−Free Plating
MAXIMUM RATINGS
Rating Symbol Value Unit
Peak Reverse Voltage VRM 40 V
Reverse Voltage VR30 Vdc
ESD Rating: Class 1C per Human Body Model
Class A per Machine Model
Maximum ratings are those values beyond which device damage can occur.
Maximum ratings applied to the device are individual stress limit values (not
normal operating conditions) and are not valid simultaneously. If these limits are
exceeded, device functional operation is not implied, damage may occur and
reliability may be affected.
