SMP5460

Overview

The InterFET SMP5460 is a P-Channel Junction Field-Effect Transistor (JFET) manufactured using the proprietary P0032F geometry. It is housed in a surface-mount SOT-23 package and operates within a junction temperature range of -55°C to 125°C. Key electrical parameters include a Gate-to-Source Breakdown Voltage of 40V, a Drain-to-Source Saturation Current ranging from -1mA to -5mA, and a Gate-to-Source Cutoff Voltage between 0.75V and 6V. The device exhibits a Forward Transconductance of 1000μS to 4000μS, an Input Capacitance of 7pF, and a Reverse Transfer Capacitance of 2pF.

Feature Summary

• Utilizes InterFET's proprietary P0032F geometry for optimized performance.
• Designed for sensitive amplifier stages with low input capacitance.
• RoHS compliant construction available in multiple packaging options.

Applications

• Audio Amplifiers
• General Purpose Amplifiers

Procurement Notes

Verify that the specific procurement order matches the required package type, as the SMP5460 designation specifically indicates the Surface Mount SOT-23 variant. Confirm whether bulk or tape-and-reel quantities are needed, as packaging specifications differ significantly between these fulfillment methods. Ensure all design validations account for the absolute maximum ratings provided in the official datasheet.

Selection Notes

Select the SMP5460 when a surface-mount P-Channel JFET is required for mid-frequency applications. This component is suitable for designs prioritizing low noise and high impedance signal sources. Compare the specific transconductance and saturation current requirements against the 2N5461 and 2N5462 variants if different gain characteristics are necessary for the target circuit topology.

Part Context

The SMP5460 belongs to the 2N5460 series of P-Channel JFETs produced by InterFET. While the standard through-hole versions utilize TO-92 packaging, the SMP5460 variant is specifically configured for surface-mount technology using the SOT-23 form factor. This series is engineered primarily for low-level audio and general-purpose amplification tasks involving high impedance signal sources.

Replacement Considerations

The 2N5460 serves as the direct through-hole equivalent. For other surface-mount options, consider the SMP5461 or SMP5462 depending on required transconductance levels. Verify pinout compatibility and thermal dissipation limits before substituting any alternative components.
