2N4093 TIN/LEAD

Jfets Overview

The Central Semiconductor Corp 2N4093 is a silicon N-channel Junction Field-Effect Transistor (JFET) housed in a TO-18 cylindrical metal can package. It operates in depletion mode with a maximum drain-source breakdown voltage of 40 V and a gate-source breakdown voltage of -40 V. The device supports a continuous drain current of 100 mA and exhibits a maximum on-resistance of 50 Ohms at zero gate-source bias. It features a maximum power dissipation of 360 mW and functions within an operating temperature range from -65 °C to +200 °C.

Jfets Feature Summary

• High-temperature operation capability up to 200 °C
• Metal can construction for robust environmental sealing
• Depletion mode operation suitable for constant current sources

Jfets Applications

• High-temperature analog signal switching
• Constant current source circuits
• Low-noise preamplifier stages

Jfets Procurement Notes

Verify the specific terminal plating configuration, as the model designation implies tin/lead finish which may differ from standard lead-free variants. Confirm RoHS compliance status, as historical Central Semiconductor JFETs often utilize non-compliant materials. Validate the TO-18 pinout assignment against the specific datasheet revision to ensure correct circuit integration.

Jfets Selection Notes

Select this component when high thermal stability is required beyond standard plastic packages. The TO-18 metal case provides superior heat dissipation compared to smaller surface-mount alternatives. Ensure the circuit design accommodates the negative gate-source voltage requirements inherent to N-channel JFET depletion mode operation.
