NTE555
Silicon Pin Diode
UHF/VHF Detector
Description:
The NTE555 is designed primarily for high–efficiency UHF and VHF detector applications. It is readily
adaptable to may other fast switching RF and digital applications.
Features:
D Schottky Barrier Construction Provides Stable Characteristics by Eliminating
the “Cat–Whisker” or “S–Bend” Contact
D Very Low Capacitance: 1.0pF
D Extremely Low Minority Carrier Lifetime: 100ps (Max)
D High Reverse Voltage: VR = 50V
D Low Reverse Leakage Current: IR = 200nA (Max)
Absolute Maximum Ratings: (TJ = +125°C, unless otherwise indicated)
