PAD50
LOW LEAKAGE
PICO-AMP DIODE
Linear Systems replaces discontinued Siliconix PAD50
The PAD50 is a low leakage Pico-Amp Diode packaged in hermetic
TO-72
The PAD50 extremely low-leakage diode provides a
superior alternative to conventional diode
technology when reverse current (leakage) must be
minimized. The PAD50 features a leakage current of
-50 pA and is well suited for use in applications such as
input protection for operational amplifiers.
