PN4092

Overview

The PN4092 is an N-channel silicon junction field-effect transistor (JFET) designed for low-level analog switching applications. It operates in depletion mode with a maximum drain-gate voltage of 40 V and a gate-source breakdown voltage of -40 V. The device features a zero-gate voltage drain current (IDSS) range of 15 mA to 8.0 mA at VDS = 20 V. Its drain-source on resistance (rDS(on)) is specified between 30 Ω and 80 Ω at ID = 1.0 mA. Key switching parameters include a turn-on time of 35 ns and a turn-off time of 60 ns under specific test conditions.

Feature Summary

Designed specifically for low-level analog signal routing and switching tasks
Capable of operation within sample and hold circuit architectures
Suitable for integration into chopper-stabilized amplifier topologies

Applications

Low level analog switching circuits
Sample and hold circuits
Chopper stabilized amplifiers

Procurement Notes

Verify the manufacturer origin, as Fairchild Semiconductor products are now managed by ON Semiconductor. Confirm that the ordering suffix matches the required package type, such as TO-92 or SOT-23, as these affect physical dimensions and mounting methods. Ensure compliance with RoHS directives if required for the specific assembly process. Cross-reference datasheet revision levels to confirm electrical characteristics align with current production standards.

Selection Notes

Select the PN4092 when a moderate IDSS range of 15 mA to 8.0 mA is required for analog signal paths. Choose this component over PN4091 or PN4093 based on specific impedance matching needs, as it offers intermediate on-resistance values. Consider the TO-92 or SOT-23 package availability depending on board space constraints and thermal dissipation requirements relative to the total device power dissipation limits.

Part Context

This component belongs to a family of N-channel JFET switches that includes the PN4091 and PN4093 variants. These devices share similar structural designs but differ in their IDSS and rDS(on) specifications to suit various impedance levels. The PN4092 provides a middle-ground performance profile within this series, sourced from Process 51 technology.
