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 pA and is well suited for use in applications such as

input protection for operational amplifiers.

LSDPAD50 Benefits:

 Negligible Circuit Leakage Contribution

 Circuit “Transparent” Except to Shunt

High-Frequency Spikes

 Simplicity of Operation

LSDPAD50 Applications:

 Op Amp Input Protection

 Multiplexer Overvoltage Protection

The LSDPAD50 is a low leakage Monolithic Dual Pico-Amp Diode
