Overview
The SMP4416TR is an N-channel JFET from InterFET, utilizing the proprietary N0026S geometry. It operates with a gate-to-source breakdown voltage of -30V and a drain-to-source saturation current (IDSS) of 5mA. The device features a forward transconductance (GFS) of 4500µS and low input capacitance (Ciss) of 4pF at 1MHz. It is housed in a SOT-23 package and supplied in a 7-inch tape and reel configuration.
Feature Summary
- Utilizes InterFET N0026S geometry for optimized performance
- Provides low noise characteristics with typical 4 nV/√Hz specification
- Exhibits extremely low gate leakage, typically less than 10pA at room temperature
- Available in surface mount SOT-23 packaging
Applications
- Sensitive mixer designs
- VHF amplifier circuits
Procurement Notes
Verify that the specific part number corresponds to the standard 2N4416 variant rather than the 'A' variant, as the datasheet distinguishes between them based on breakdown voltage ratings. Confirm the reel size matches the required production volume, noting that the 7-inch reel supports up to 3,000 pieces. Ensure compliance with RoHS standards if required by the end application.
Selection Notes
Select this component when designing circuits requiring low noise and high linearity at VHF frequencies. The SOT-23 package is suitable for space-constrained surface mount applications. Consider the -30V gate-source rating for appropriate biasing networks. Compare against the 2N4416A if higher breakdown voltage is necessary, though this requires verifying pinout compatibility.
Part Context
This component belongs to the InterFET 2N4416 family of N-channel JFETs. The SMP4416TR designation specifically indicates the surface mount SOT-23 version packaged in a tape and reel format. It shares electrical characteristics with the through-hole 2N4416 but differs in physical packaging and mounting style.
Replacement Considerations
The SMP4416A is a compatible alternative within the same family, offering a higher gate-to-source breakdown voltage of -35V compared to the -30V of the SMP4416. Both share identical pinouts and most electrical parameters.
