Overview
The PN4392 TRE TIN/LEAD is an N-channel Junction Field-Effect Transistor (JFET) manufactured by Central Semiconductor. It utilizes silicon technology and is housed in a TO-92-3 through-hole package. Key electrical specifications include a gate-source breakdown voltage of 40 V, a drain-source on-resistance of 60 Ohms, and a power dissipation rating of 625 mW. The device supports a drain-source current of 75 mA at zero gate-source voltage and operates within a temperature range of -65°C to +150°C.
Feature Summary
- N-channel JFET configuration for signal amplification and switching
- Silicon-based construction ensuring stable performance across wide temperature ranges
- Through-hole mounting capability via TO-92-3 package
Applications
- Low-noise audio preamplifier circuits
- High-impedance input stages in measurement equipment
- Analog switch applications requiring low leakage current
Procurement Notes
Verify the specific ordering suffix against manufacturer documentation to confirm lead-free versus tin/lead compliance status. Confirm RoHS directive adherence requirements with the supplier prior to purchase. Ensure the requested quantity aligns with minimum order quantities specified in official distributor catalogs. Validate that the TO-92-3 package type matches the target PCB footprint design constraints.
Selection Notes
Select this component when an N-channel JFET with moderate current handling and high input impedance is required. The TO-92-3 package suits designs prioritizing through-hole assembly over surface mount alternatives. Compare Idss and Rds(on) values against circuit requirements to ensure compatibility with existing biasing networks. Consider thermal management capabilities given the 625 mW power dissipation limit in enclosed environments.
Part Context
This part belongs to the PN4392 series of N-channel JFETs produced by Central Semiconductor. It shares core electrical characteristics with other variants in the family but differs in packaging and terminal plating options. The TRE designation typically indicates a tape and reel packaging format, while the TIN/LEAD suffix specifies the terminal material composition for solderability and environmental compliance purposes.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Verify pinout compatibility and electrical parameter tolerances before considering any alternative JFET devices from different manufacturers.
