MBD301/D
MBD301, MMBD301LT1
Preferred Device
Silicon Hot−Carrier Diodes
SCHOTTKY Barrier Diodes
These devices are designed primarily for high−efficiency UHF and
VHF detector applications. They are readily adaptable to many other
fast switching RF and digital applications. They are supplied in an
inexpensive plastic package for low−cost, high−volume consumer
and industrial/commercial requirements. They are also available in a
Surface Mount package.
Features
Extremely Low Minority Carrier Lifetime − 15 ps (Typ)
Very Low Capacitance − 1.5 pF (Max) @ VR = 15 V
Low Reverse Leakage − IR = 13 nAdc (Typ) MBD301, MMBD301
Pb−Free Packages are Available

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 a ffected.
