SMP5114TR

Overview

The SMP5114TR is a P-Channel JFET from InterFET, part of the 2N5114 series, housed in an SOT23 package. It features a Gate-to-Source Breakdown Voltage (BVGSS) of 30 V and a Drain-to-Source Saturation Current (IDSS) ranging from -30 mA to -90 mA. The device exhibits a Gate-to-Source Cutoff Voltage (VGS(off)) between 5 V and 10 V. Static Drain-to-Source ON Resistance (RDS(ON)) is specified at 75 Ω to 100 Ω. Input Capacitance (Ciss) measures 25 pF at 1 MHz.

Feature Summary

• Utilizes InterFET proprietary P0099F geometry for optimized performance.
• Provides low on-resistance characteristics suitable for efficient signal switching.
• Delivers typical noise levels of 8 nV/√Hz for high-fidelity analog applications.

Applications

• Analog switches
• Chopper circuits

Procurement Notes

Verify the specific suffix TR indicates tape and reel packaging with maximum quantities of 3,000 pieces on 7-inch reels or 9,000 pieces on 13-inch reels. Confirm the base part number corresponds to the 2N5114 electrical specifications rather than other variants in the family. Ensure the ordering documentation explicitly references the SOT23 surface mount configuration.

Selection Notes

Select this component when designing circuits requiring a P-Channel JFET with a 30 V breakdown voltage and low input capacitance. The SOT23 package facilitates surface mount assembly. Evaluate the IDSS range of -30 mA to -90 mA against circuit biasing requirements. Consider the 75 Ω to 100 Ω RDS(ON) for voltage drop calculations in the selected operating region.

Part Context

This device belongs to the 2N5114-5-6 product family manufactured by InterFET Corporation. The series includes multiple binning options for saturation current and cutoff voltage. The SMP5114 variant specifically designates the surface mount SOT23 form factor within this lineup of P-Channel JFETs designed for precision analog switching.

Replacement Considerations

Direct substitutes include SMP5115TR and SMP5116TR from the same manufacturer. These alternatives share the SOT23 package but differ in IDSS and VGS(off) parameters. Verify that the alternative part's electrical ranges align with the specific design constraints before substitution.

FAQ

What is the maximum continuous forward gate current?

The maximum continuous forward gate current is 50 mA.

Does the SMP5114 support military applications?

While the TO-18 package is hermetically sealed for military use, the SMP5114 uses an SOT23 plastic package. Verify specific environmental ratings for harsh conditions.

What is the operating junction temperature range?

The operating junction temperature range is -55°C to 125°C.
