Overview
The PN4092 PBFREE is an N-channel Junction Field-Effect Transistor (JFET) manufactured by Central Semiconductor Corp. It utilizes silicon technology and is housed in a TO-92-3 through-hole package. Key electrical specifications include a drain-source breakdown voltage of 40 V, a gate-source breakdown voltage of 40 V, and a maximum power dissipation of 625 mW. The device features a gate-source cutoff voltage of 7 V and a zero-gate-voltage drain current of 15 mA. It operates within a temperature range of -65°C to +150°C.
Feature Summary
- N-channel JFET configuration for signal amplification and switching applications
- Silicon-based construction ensuring stable performance across wide temperature ranges
- Through-hole mounting capability in a standard TO-92-3 package
Applications
- Low-noise audio preamplifier stages
- High-impedance buffer circuits
- Constant current source implementations
Procurement Notes
Verify the specific ordering suffix and packaging format directly with the manufacturer or authorized distributors before purchase. Confirm that the component meets RoHS compliance requirements if necessary for your assembly process. Ensure the lead time aligns with production schedules, as availability may vary. Cross-reference the datasheet parameters against your circuit design requirements to ensure compatibility.
Selection Notes
Select this component when an N-channel JFET with a 40 V breakdown voltage and 15 mA IDSS is required. Consider the TO-92-3 package for through-hole designs. Compare the 7 V gate-source cutoff voltage against other models like the PN4091 or PN4093 if different transconductance characteristics are needed. Verify thermal management capabilities given the 625 mW power dissipation limit.
Part Context
The PN4092 belongs to the PN409x series of N-channel JFETs from Central Semiconductor. This series includes variants such as the PN4091, PN4092, and PN4093, which share similar voltage ratings but differ in gate-source cutoff voltage and drain current specifications. These devices are designed for general-purpose discrete semiconductor applications requiring reliable field-effect transistor performance.
Replacement Considerations
Check for direct pin-compatible substitutes within the same series, such as the PN4091 or PN4093, noting differences in cutoff voltage and drain current. Verify that any alternative JFET matches the 40 V voltage rating and TO-92-3 package form factor.
