PN4093

Overview

The Fairchild Semiconductor PN4093 is a small-signal N-channel silicon Junction Field-Effect Transistor (JFET) designed for low-level analog applications. It operates in depletion mode with a single element configuration housed in a TO-92 cylindrical package. Key electrical characteristics include a maximum drain-source voltage of 40 V, a gate-source breakdown voltage of 40 V, and a maximum power dissipation of 625 mW. The device features an on-state resistance of 80 Ohms at zero gate-source voltage and supports a wide operating temperature range from -65°C to +150°C.

Feature Summary

Designed specifically for low-level analog switching operations
Capable of functioning within sample and hold circuit architectures
Suitable for integration into chopper-stabilized amplifier designs

Applications

Low level analog switching
Sample and hold circuits
Chopper stabilized amplifiers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm pinout compatibility and material composition. Ensure the component meets required environmental standards for the intended deployment environment. Cross-reference the manufacturing date code to assess potential obsolescence risks or supply chain constraints associated with legacy semiconductor inventory management protocols.

Selection Notes

Select this component when designing circuits requiring robust N-channel JFET performance for precision analog signal routing. The high breakdown voltage ratings support operation in moderately high-voltage environments. Consider the through-hole TO-92 packaging constraint during printed circuit board layout planning to ensure adequate mechanical stability and thermal dissipation pathways are established for reliable long-term system operation.

Part Context

This part belongs to the PN409x family of small-signal field-effect transistors manufactured by Fairchild Semiconductor. The series includes complementary variants such as the PN4091 and PN4092, which share similar structural characteristics but differ in specific threshold parameters. These devices represent standard discrete semiconductor solutions for general-purpose analog signal processing tasks in industrial and consumer electronics.
