LSDPAD50 LOW LEAKAGE PICO-AMP DUAL DIODE Linear Systems replaces discontinued Siliconix LSDPAD50 The LSDPAD50 is a low leakage Monolithic Dual Pico-Amp Diode The LSDPAD50 extremely low-leakage monolithic dual diode provides a superior alternative to conventional diode technology when reverse current (leakage) must be minimized. In addition the monolithic dual construction allows excellent capacitance matching per diode. The LSDPAD50 Features a leakage current of 50 p A and is well suited for use in applications such as input protection for operational amplifiers.
