# LSDPAD1 Low Leakage Pico-Amp Dual Diode

## Key Features

· Direct replacement for Siliconix LSDPAD1
· High isolation (20fA)
· Excellent capacitance matching (∆CR ≤ 0.2pF)
· Ultralow leakage (≤ 1 pA)
· Reverse breakdown voltage (BVR) ≥ -45V
· Reverse capacitance (Crss) ≤ 0.8pF

## Absolute Maximum Ratings

· Storage Temperature: -65°C to +150°C
· Operating Junction Temperature: -55°C to +135°C
· Continuous Power Dissipation: 500mW
· Forward Current: 50mA

## Electrical Characteristics (at 25°C)

· Reverse Breakdown Voltage (BVR): -45V (IR = -1µA)
· Forward Voltage (VF): 0.8 - 1.5V (IF = 1mA)
· Total Reverse Capacitance (Crss): ≤ 0.8pF (VR = -5V, f = 1MHz)
· Differential Capacitance (∆CR): ≤ 0.2pF (VR1=VR2= -5V, f = 1MHz)
· Maximum Reverse Leakage Current (IR): ≤ -1 pA (VR = -20V)

## Benefits & Applications

· Negligible circuit leakage contribution
· Circuit “transparent” except for shunt high-frequency spikes
· Simplicity of Operation
· Op Amp Input Protection
· Multiplexer Overvoltage Protection

## Packages

· TO-78
· Bare die (contact Micross for dimensions)

## Notes

· Absolute maximum ratings indicate limits beyond which serviceability may be impaired.
