Overview
The SMP5462TR is a surface-mount P-Channel JFET in the SOT-23 package, designed for sensitive amplifier stages. It features a Gate-to-Source Breakdown Voltage of 40V and a Drain-to-Source Saturation Current range of -4mA to -16mA. The device offers a Forward Transconductance between 2000μS and 6000μS, with an Input Capacitance of 7pF and Reverse Transfer Capacitance of 2pF at 1MHz. It operates within a junction temperature range of -55°C to 125°C.
Feature Summary
- Utilizes InterFET P0032F geometry for optimized performance
- Provides low input capacitance suitable for high-frequency applications
- Designed for higher gain applications with elevated transconductance
Applications
- Audio Amplifiers
- General Purpose Amplifiers
- Sensitive amplifier stages for mid-frequencies designs
Procurement Notes
Verify the specific suffix TR indicates tape and reel packaging when ordering. Confirm that the component meets RoHS compliance requirements for your assembly process. Ensure the design accounts for the maximum continuous power dissipation limits and thermal derating characteristics specified in the datasheet to maintain reliability under all operating conditions.
Selection Notes
Select this model for applications requiring higher gain compared to the 2N5460 or 2N5461 variants due to its typical transconductance of 3.5mS. Consider the SOT-23 form factor for space-constrained surface mount designs. Evaluate the noise figure and input capacitance specifications against the signal source impedance to ensure optimal signal integrity in the target circuit topology.
Part Context
This component belongs to the 2N5460/5461/5462 family of P-Channel JFETs manufactured by InterFET. While the through-hole TO-92 versions are available as bulk components, the SMP5462TR specifically denotes the surface mount SOT-23 variant packaged in tape and reel format for automated assembly processes.
Replacement Considerations
Direct functional equivalents include the SMP5460TR and SMP5461TR from the same manufacturer series. Cross-manufacturer replacements must match the 40V breakdown voltage and P-Channel configuration while verifying pinout compatibility with the SOT-23 footprint.
