PAD20_TO-72 Datasheet, PDF (1/1 Pages) Micross Components – PICO-AMP DIODE

PAD20
LOW LEAKAGE
PICO-AMP DIODE
Linear Systems replaces discontinued Siliconix PAD20
The PAD20 is a low leakage Pico-Amp Diode packaged in hermetic TO-72
The PAD20 extremely low-leakage diode provides a
superior alternative to conventional diode
technology when reverse current (leakage) must be
minimized. The PAD20 features a leakage current of
-20 pA and is well suited for use in applications such as
input protection for operational amplifiers.
PAD20 Benefits:
ƒ Negligible Circuit Leakage Contribution
ƒ Circuit “Transparent” Except to Shunt
High-Frequency Spikes
ƒ Simplicity of Operation
PAD20 Applications:
ƒ Op Amp Input Protection
ƒ Multiplexer Overvoltage Protection
