The DPAD50 is a low leakage Monolithic Dual Pico-Amp Diode
Linear Systems replaces discontinued Siliconix DPAD50

The DPAD50 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 DPAD50 features a leakage current of -50 pA and is well suited for use in applications such as input protection for operational amplifiers.
