Overview
The PN4392 APM 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 maximum drain-to-gate voltage of 40 V, a gate-to-source breakdown voltage of 40 V, and a gate-to-source cutoff voltage of 5 V. The device supports a drain-source current of 75 mA at zero gate-source voltage, with a drain-source on-resistance of 60 Ohms. Power dissipation is rated at 625 mW, and the operating temperature range spans from -65°C to +150°C.
Feature Summary
- N-channel silicon JFET construction for signal processing applications
- Through-hole TO-92-3 packaging compatible with standard mounting techniques
- High gate-to-source breakdown voltage capability for robust operation
- Extended thermal stability suitable for demanding environmental conditions
Applications
- Low-noise amplifier circuits
- Analog switching applications
- Voltage-controlled resistor implementations
Procurement Notes
Verify the specific suffix 'APM TIN/LEAD' against official datasheets to confirm lead composition and plating requirements. Ensure compatibility with RoHS exemptions if applicable. Confirm package marking and pinout alignment with design schematics before integration. Request manufacturer certification for tin-lead termination quality and whisker resistance if required for high-reliability environments.
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 facilitates easy prototyping and through-hole assembly. Consider the 60 Ohm on-resistance and 75 mA current limit for circuit design constraints. Verify thermal management capabilities given the 625 mW power dissipation rating and wide operating temperature range.
Part Context
This part belongs to the PN4392 series of N-channel JFETs produced by Central Semiconductor. The series offers various packaging and termination options to suit different manufacturing needs. The PN4392 variant specifically provides balanced performance for general-purpose analog applications requiring reliable field-effect transistor characteristics.
Replacement Considerations
Consult official substitution guides for equivalent N-channel JFETs in TO-92 packages. Verify that alternative parts match the 40 V voltage ratings and 75 mA current limits. Ensure pinout compatibility and thermal characteristics align with the original design requirements.
