2N5461RLRA

Overview

The 2N5461RLRA is a small-signal P-channel junction field-effect transistor (JFET) manufactured by onsemi. It is housed in a TO-92 plastic package with three leads, designed for through-hole mounting. The device operates within a temperature range of -55 °C to +150 °C and features a maximum power dissipation of 310 mW. Key electrical characteristics include a drain-source breakdown voltage of 25 V and a gate-source cutoff voltage ranging from -0.5 V to -6 V. The saturation current is specified at a minimum of 1 µA, supporting its use in low-noise analog switching and amplification circuits.

Feature Summary

• P-channel JFET configuration suitable for signal path control
• Low noise performance for sensitive analog applications
• High thermal stability with extended operating temperature range

Applications

• Low-noise audio preamplifiers
• Analog switch matrices
• Voltage-controlled resistors in tuning circuits

Procurement Notes

Verify the specific suffix RLRA against official datasheets to confirm packaging and reel specifications. Ensure compatibility with RoHS directives if required by the target assembly process. Cross-reference pinout configurations with legacy equivalents to prevent board layout errors during integration.

Selection Notes

Select this component when a P-channel JFET with low input bias current and high linearity is required. Compare the 25 V breakdown voltage against circuit supply rails to ensure adequate headroom. Evaluate the -0.5 V to -6 V pinch-off voltage range to match the desired control threshold for the specific application design.

Part Context

This part belongs to the standard discrete semiconductor family of junction field-effect transistors. It serves as a fundamental active component for analog signal processing. The TO-92 form factor provides a compact solution for general-purpose electronic designs requiring reliable FET switching capabilities.

Replacement Considerations

Direct substitutes include the 2N5460 (N-channel counterpart) or generic P-channel JFETs like the MPF102, provided pinouts and electrical limits align. Verify that alternative parts meet the same thermal and voltage requirements for seamless integration.
