PAD20

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.
