2N4393 TIN/LEAD

Jfets Overview

The 2N4393 TIN/LEAD is a silicon N-channel Junction Field-Effect Transistor (JFET) manufactured by Central Semiconductor Corp. It features a maximum drain-source voltage of 40V and a gate-source breakdown voltage of -40V. The device supports a continuous drain current of up to 75mA at zero gate-source voltage, with a maximum power dissipation of 625mW. Designed for through-hole mounting, it utilizes the TO-92-3 package configuration. The component operates within a junction temperature range of -65°C to +150°C and includes tin/lead plating on its terminations.

Jfets Feature Summary

• Utilizes silicon JFET technology for reliable signal processing
• Features hermetic sealing in a TO-92-3 through-hole package
• Includes tin/lead plating to prevent tin whisker formation

Jfets Applications

• High-reliability aerospace electronic devices
• Military circuit applications requiring specific termination standards

Jfets Procurement Notes

Verify that the TIN/LEAD suffix is explicitly included in the purchase order to ensure the correct plating specification. Confirm RoHS compliance status as tin/lead variants may differ from lead-free equivalents. Request the official datasheet to validate electrical parameters against specific design requirements before integration into production circuits.

Jfets Selection Notes

Select this component when a high-reliability N-channel JFET with specific termination requirements is necessary. Ensure the 40V voltage rating and 625mW power dissipation align with the circuit's operational limits. Consider the TO-92-3 package dimensions for PCB layout compatibility and verify thermal management capabilities for the intended operating environment.

Jfets Part Context

This part belongs to the Central Semiconductor 2N4393 series of small-signal field-effect transistors.
