Description
DPAD100 LOW LEAKAGE PICO-AMP DUAL DIODE
Linear Systems replaces discontinued Siliconix DPAD100
The DPAD100 is a low leakage Monolithic Dual Pico-Amp Diode
The DPAD100 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 DPAD100 features a leakage current of 100 pA and is well suited for use in applications such as input protection for operational amplifiers. FEATURES DIRECT REPLACEMENT FOR SILICONIX DPAD100 HIGH ON ISOLATION EXCELLENT CAPACITANCE MATCHING ULTRALOW LEAKAGE REVERSE BREAKDOWN VOLTAGE REVERSE CAPACITANCE ABSOLUTE MAXIMUM RATINGS @ 25°C (unless otherwise noted) Maximum Temperatures Storage Temperature Operating Junction Temperature Maximum Power Dissipation Continuous Power Dissipation MAXIMUM CURRENT Forward Current (Note 1)
