CP216-2N4392-WN

Overview

The Central Semiconductor Corp CP216-2N4392-WN is a specialized variant of the 2N4392 N-channel Junction Field-Effect Transistor (JFET). This component utilizes silicon technology and is housed in a TO-18 metal can package. It operates with a maximum drain-source voltage rating of 40V. The device is designed for low-noise amplification applications, featuring a typical gate reverse current of 1nA at -20V and a minimum forward transfer admittance (Yfs) of 1500µS. The unit weight is approximately 300mg, and it supports an operating temperature range extending up to +175°C junction temperature.

Feature Summary

• Low-noise performance suitable for sensitive signal amplification
• High input impedance characteristic inherent to JFET architecture
• Robust metal can construction providing environmental protection

Applications

• Low-noise preamplifier stages in audio equipment
• Precision analog signal conditioning circuits
• High-impedance buffer amplifiers

Procurement Notes

Verify the specific suffix 'CP216' against the manufacturer's official datasheet to confirm if it denotes a unique binning or testing standard compared to the standard 2N4392. Ensure that the TO-18 package dimensions match the target PCB footprint requirements. Confirm RoHS compliance status directly with Central Semiconductor documentation prior to finalizing procurement specifications.

Selection Notes

Select this component when high input impedance and low noise figures are critical design constraints. Compare the Yfs minimum values against circuit gain requirements. Ensure the TO-18 package style aligns with available mounting infrastructure. Verify thermal management capabilities given the 175°C junction temperature limit under expected power dissipation conditions.

Part Context

This part belongs to the broader family of N-channel JFETs manufactured by Central Semiconductor. It shares core electrical characteristics with the standard 2N4392 but may include specific screening criteria indicated by the prefix. It serves as a discrete semiconductor solution for analog front-end designs requiring minimal signal distortion.

Replacement Considerations

Direct replacements include the standard 2N4392 from Central Semiconductor or equivalent N-channel JFETs from other manufacturers such as MMBFJ175LT1G, provided pinouts and voltage ratings are compatible. Verify that substitute components meet the same low-noise and Yfs specifications.
