2N5116 TO-18 3L ROHS

Jfets Overview

The Linear Integrated Systems 2N5116 is a single P-channel JFET switch designed as a replacement for the Siliconix 2N5116. It operates in depletion mode with a maximum gate-to-source breakdown voltage of 30V and a continuous power dissipation of 500mW at 25°C. The device features a typical drain-to-source on resistance of 75Ω and a reverse transfer capacitance of 6pF to 7pF. Static characteristics include a gate-to-source cutoff voltage range of 1V to 4V and a saturation current between -5mA and -55mA. Dynamic performance specifies a forward transconductance of 4.5mS and an equivalent noise voltage of 20nV/√Hz.

Jfets Feature Summary

• Designed as a direct replacement for discontinued Siliconix 2N5114, 2N5115, and 2N5116 devices.
• Optimized for low insertion loss applications through minimized on-resistance and feedback capacitance.
• Capable of handling high-speed switching operations with defined turn-on and turn-off time parameters.

Jfets Applications

• High-speed analog signal switching
• Low-noise preamplifier input stages
• Voltage-controlled resistor circuits

Jfets Procurement Notes

Verify that the specific procurement order explicitly lists the manufacturer as Linear Integrated Systems to ensure compliance with the provided datasheet specifications. Confirm the package style matches the required TO-18 metal can configuration. Ensure the component lot aligns with the revision A7 documentation standards referenced in the official product data.

Jfets Selection Notes

Select this component when a verified drop-in replacement for legacy Siliconix P-channel JFETs is required. Evaluate the 75Ω typical on-resistance against circuit load requirements. Consider the 6pF to 7pF reverse transfer capacitance for high-frequency signal integrity. Verify that the 30V breakdown voltage meets the system's maximum operating limits.
