Motorola Small–Signal Transistors, FETs and Diodes Device Data

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.

• The Schottky Barrier Construction Provides Ultra–Stable Characteristics by

Eliminating the “Cat–Whisker” or “S–Bend” Contact

• 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
