Overview
The LSJ74C TO-92 3L ROHS is a P-channel Junction Field-Effect Transistor (JFET) manufactured by Linear Integrated Systems, Inc. It features a maximum drain-source voltage of 25 V and a continuous drain current rating of 10 mA. The device is housed in a TO-92 through-hole package with three leads. It has a maximum power dissipation of 400 mW. This component is designed for low-noise applications, offering high input impedance and stable performance suitable for precision analog signal processing tasks.
Feature Summary
- P-channel JFET configuration optimized for ultra-low noise audio and acoustic applications
- High input impedance characteristics suitable for sensitive signal detection
- RoHS compliant construction available in standard through-hole packaging
Applications
- Ultra-low noise audio preamplifiers
- Acoustic sensor interface circuits
- Precision analog signal conditioning
Procurement Notes
Verify the specific suffix 'C' against the manufacturer's latest datasheet to confirm pinout and electrical tolerances. Ensure the ordering part number matches the required RoHS compliance status. Cross-reference the TO-92 lead configuration with the schematic footprint to prevent assembly errors during integration into the target circuit board design.
Selection Notes
Select this component when designing circuits requiring P-channel JFETs with low noise profiles. Consider the 25 V voltage limit and 10 mA current capacity relative to the load requirements. Evaluate the thermal management needs given the 400 mW power dissipation rating within the TO-92 package constraints for the intended operating environment.
Part Context
This part belongs to the LSJ/SST74 series from Linear Integrated Systems, Inc., which specializes in low-noise transistors. The series includes variants like the LSJ74A and is available in multiple packages including SOT-89 and die form. These devices are engineered for high-performance analog applications where signal integrity is critical.
Replacement Considerations
The LSJ74A is a related variant within the same series. Verify if the specific parameter differences between the 'A' and 'C' suffixes affect the circuit operation before substitution. Check datasheet specifications for both parts to ensure compatibility with existing design constraints.
