PAD50

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.
