ID100 TO-78 6L

RF Diode Overview

The ID100 is a monolithic dual picoampere diode housed in a TO-78 package. It features a reverse breakdown voltage of 30V and a forward voltage of 0.8V typical at 10mA. Reverse leakage current is specified at 0.1pA with a maximum of 2.0pA at 10V reverse bias. Total reverse capacitance is 0.75pF at 10V and 1MHz. The device supports continuous power dissipation of 300mW and operates within a junction temperature range of -55°C to +150°C.

RF Diode Feature Summary

• Monolithic dual configuration providing two matched diodes in a single package
• Ultra-low reverse leakage current suitable for precision analog applications
• Low total reverse capacitance minimizing signal distortion in high-frequency circuits
• Direct replacement compatibility with legacy Intersil ID100 components

RF Diode Applications

• Operational amplifier input protection against differential voltage overstress
• Sample and hold circuit offset voltage reduction by clipping gate-fed capacitance
• Precision rectifier circuits requiring minimal leakage error
• High-impedance sensor interface protection

RF Diode Procurement Notes

Verify the specific ordering suffix matches the required package style, as the ID100 denotes the TO-78 variant while the ID101 uses TO-71. Confirm that pins 3 and 5 remain unconnected during installation to prevent circuit malfunction. Ensure the supplier provides documentation confirming compliance with the electrical characteristics listed in the official datasheet revision A4.

RF Diode Selection Notes

Select this component when ultra-low leakage and capacitance are critical for maintaining signal integrity in high-impedance nodes. The TO-78 metal can package offers robust shielding compared to plastic alternatives. Consider the ID101 if a smaller TO-71 footprint is required, noting that pinout and mechanical dimensions differ. Validate thermal management requirements given the 300mW dissipation limit at 25°C ambient.

RF Diode Part Context

Linear Integrated Systems manufactures the ID100 as part of its precision discrete semiconductor line. The company leverages heritage processes from Amelco, Union Carbide, and Intersil to produce these high-reliability components. This product serves as a direct drop-in replacement for older Intersil offerings, supporting legacy designs requiring picoampere-level performance without redesigning the surrounding circuitry.

RF Diode Replacement Considerations

The ID100 is explicitly documented as a direct replacement for the Intersil ID100. No other substitute part numbers are verified in the provided source material.
