Overview
The InterFET SMP4416ATR is an N-channel Junction Field-Effect Transistor (JFET) utilizing the proprietary N0026S geometry. It is housed in a surface-mount SOT-23 package and supplied in a 7-inch tape and reel configuration with a maximum quantity of 3,000 pieces per reel. The device features a gate-to-source breakdown voltage of -35 V and a drain-to-source saturation current ranging from 5 mA to 15 mA. Forward transconductance is specified between 4,500 µS and 7,500 µS at 1 kHz. Input capacitance is typically 4 pF at 1 MHz.
Feature Summary
- Utilizes InterFET N0026S geometry for optimized performance characteristics
- Provides low noise operation with typical input noise voltage of 4 nV/√Hz
- Exhibits extremely low gate leakage current, typically less than 10 pA at room temperature
- Compliant with RoHS standards for environmental safety
Applications
- Sensitive mixer circuits
- VHF amplifier designs
Procurement Notes
Verify that the specific part number suffix corresponds to the required packaging format. Confirm the device variant matches the necessary electrical specifications, particularly regarding breakdown voltage ratings. Ensure the ordering quantity aligns with the minimum requirements associated with the tape and reel packaging type selected.
Selection Notes
Select this component when low noise and high linearity are critical for RF signal processing. The SOT-23 package facilitates automated surface-mount assembly processes. Consider the higher breakdown voltage of the 'A' variant if circuit conditions require increased gate-to-source voltage tolerance compared to standard JFET options.
Part Context
This component belongs to the 2N4416 family of N-channel JFETs manufactured by InterFET. The SMP4416ATR designation specifically identifies the surface-mount version packaged in a tape and reel format. This family is engineered for high-frequency applications requiring stable performance across varying temperature conditions.
Replacement Considerations
Direct substitutes include the SMP4416 and SMP4416A bulk packages. Other variants within the same family, such as the through-hole 2N4416 or PN4416, offer identical electrical characteristics but differ in physical mounting style.
