The DPAD20 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 DPAD20 features a leakage current of -20

pA and is well suited for use in applications such as

input protection for operational amplifiers.

DPAD20 Benefits:



Negligible Circuit Leakage Contribution



Circuit “Transparent” Except to Shunt

High-Frequency Spikes



Simplicity of Operation

DPAD20 Applications:



Op Amp Input Protection



Multiplexer Overvoltage Protection
