Description
Product Details

2N5461 P-Channel JFET - Low-Noise Amplifier & Analog Switch

The 2N5461 is a depletion-mode P-Channel JFET commonly used in general-purpose amplifier and analog switch circuits. Its high input impedance and low gate leakage make it a solid choice for buffer stages, impedance converters and audio-grade preamplifier designs where a matched pair of P-channel JFETs is needed alongside its N-channel counterparts.

Functions & Applications

Depletion-Mode P-Channel JFET: Conducts with zero gate-source bias, simplifying analog switch and amplifier bias design.
High Input Impedance: Minimal loading effect on preceding signal source, ideal for sensor and audio front-ends.
Low Noise Operation: Well suited to low-level, low-frequency amplifier and impedance-converter stages.
Standard TO-92 Package: Through-hole footprint, easy to prototype on breadboard or perfboard.
Part of a Matched Family: Pairs with the 2N5460/2N5462 siblings for different pinch-off voltage ranges.

Frequently Asked Questions

Q: What is the difference between the 2N5460, 2N5461 and 2N5462?
A: They are the same P-Channel JFET family with different pinch-off (VGS-off) and IDSS ranges: the 2N5461 sits in the middle, with a wider cutoff range than the 2N5460 and a narrower one than the 2N5462.

Q: Can the 2N5461 be used as an analog switch?
A: Yes, its depletion-mode P-channel structure and low leakage make it suitable for simple analog switching and chopper circuits, in addition to small-signal amplification.

Note: Price refers to one (1) piece. The component is shipped in bulk without individual packaging.
