Silicon Hot–Carrier Diodes
Schottky Barrier Diode
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 available in a Surface Mount package.
• Extremely Low Minority Carrier Lifetime – 15 ps (Typ)
• Very Low Capacitance – 1.5 pF (Max) @ V R = 15 V
• Low Reverse Leakage – I R = 13 nAdc (Typ)
• Device Marking: 4T
