SMP5461TR

Overview

The SMP5461TR is a P-Channel Junction Field-Effect Transistor (JFET) manufactured by InterFET, utilizing the proprietary P0032F geometry. It is housed in an SOT-23 surface-mount package and supplied in tape-and-reel configurations with maximum quantities of 3,000 pieces for 7-inch reels or 9,000 pieces for 13-inch reels. The device features a Gate-to-Source Breakdown Voltage of 40V minimum. Typical electrical characteristics include an Input Capacitance of 3.2pF and a Noise Voltage of 2.7 nV/√Hz.

Feature Summary

• Utilizes InterFET P0032F geometry for optimized performance
• Designed for low noise applications with typical input noise voltage of 2.7 nV/√Hz
• Features low input capacitance to support high-frequency signal integrity

Applications

• Audio Amplifiers
• General Purpose Amplifiers
• Sensitive amplifier stages for mid-frequencies designs

Procurement Notes

Verify that the specific ordering suffix corresponds to the required packaging format. Confirm whether bulk, tape-and-reel, or waffle pack options are needed based on production volume. Ensure compliance with RoHS standards if applicable to the end application requirements.

Selection Notes

Select this component when designing sensitive amplifier circuits requiring low noise and low input capacitance. The SMP5461TR offers a balance of performance suitable for mid-frequency applications. Consider the SOT-23 package constraints for surface-mount assembly processes.

Part Context

This part belongs to the 2N5460-1-2 family of P-Channel JFETs from InterFET. While the 2N5462 variant targets higher gain applications, the SMP5461TR provides intermediate characteristics within the series. The family supports various packaging options including through-hole, surface mount, and bare die formats.

Replacement Considerations

Direct replacements include other P-Channel JFETs with similar breakdown voltages and pinouts. Verify transconductance and capacitance values match circuit requirements before substitution.
