Overview
The SMP5116 is a P-Channel JFET from InterFET, utilizing the P0099F geometry. It features a Gate to Source Breakdown Voltage of 30 V and a Drain to Source Saturation Current range of -5 mA to -25 mA. The Gate to Source Cutoff Voltage ranges from 1 V to 4 V. Static Drain to Source ON Resistance is specified between 75 Ω and 150 Ω. Input Capacitance is typically 27 pF at 1 MHz. The device operates within a junction temperature range of -55°C to 125°C and supports Surface Mount SOT23 packaging.
Feature Summary
- Utilizes InterFET P0099F geometry for optimized performance in analog switching applications.
- Features low on-resistance suitable for chopper and analog switch designs.
- Provides typical noise performance of 8 nV/√Hz for signal integrity.
Applications
- Analog switches
- Choppers
Procurement Notes
Verify the specific package variant required, as the SMP5116 designation corresponds to the SOT23 surface mount option. Confirm tape and reel specifications if ordering bulk quantities exceeding standard bulk pack limits. Ensure design validation covers all field use cases and extreme conditions as per manufacturer guidelines.
Selection Notes
Select the SMP5116 when a P-Channel JFET with a 30 V breakdown voltage and low input capacitance is required. The SOT23 package facilitates surface mount integration. Consider the IDSS range of -5 mA to -25 mA and VGS(off) of 1 V to 4 V to ensure compatibility with circuit biasing requirements for analog switching or chopping functions.
Part Context
The SMP5116 belongs to the 2N5114-5-6 family of P-Channel JFETs manufactured by InterFET. This series includes through-hole TO-18 and TO-92 variants (2N5114, 2N5115, 2N5116; PN5114, PN5115, PN5116) alongside the surface mount SMP511x series. All variants share similar electrical characteristics but differ in physical packaging and mounting style.
Replacement Considerations
Direct pin-compatible replacements include the 2N5116 (TO-18), PN5116 (TO-92), and SMP5116TR (Tape and Reel). Verify that the substitute component matches the required SOT23 footprint and electrical parameters such as BVGSS and IDSS before implementation.
