The LSPAD20 extremely low-leakage diode provides a

superior alternative to conventional diode

technology when reverse current (leakage) must be

minimized. The LSPAD20 features a leakage current of

-20 pA and is well suited for use in applications such as

input protection for operational amplifiers.

LSPAD20 Benefits:

Negligible Circuit Leakage Contribution

Circuit “Transparent” Except to Shunt

High-Frequency Spikes

Simplicity of Operation

LSPAD20 Applications:

Op Amp Input Protection

Multiplexer Overvoltage Protection

LSPAD20 is a low leakage Pico-Amp Diode packaged in hermetic
