SSTDPAD50
LOW LEAKAGE
PICO-AMP DUAL DIODE
Linear Systems replaces discontinued Siliconix SSTDPAD50
The SSTDPAD50 is a low leakage Monolithic Dual Pico-Amp Diode
The SSTDPAD50 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 SSTDPAD50
features a leakage current of -50 pA and is well suited
for use in applications such as input protection for
