Overview
The MMBF5460LT1 is a P-channel Junction Field-Effect Transistor (JFET) manufactured by onsemi. Designed for general-purpose applications, it features a single channel configuration housed in a surface-mount SOT-23 package with three pins. The device supports a maximum drain-source voltage of 30 V and operates within a junction temperature range of -55°C to 150°C. It has a maximum power dissipation of 225 mW and dimensions of 2.9 mm in length and 0.94 mm in height.
Feature Summary
- P-channel JFET architecture suitable for low-noise analog signal processing
- Compact SOT-23 surface-mount packaging for automated assembly
- Wide operating temperature range supporting harsh environments
Applications
- Low-noise amplifier circuits
- Impedance conversion stages
- Analog switching applications
Procurement Notes
Verify the component authenticity through official onsemi channels or authorized distributors. Confirm the specific datasheet revision matches design requirements. Ensure the SOT-23 footprint aligns with PCB layout specifications. Check for RoHS compliance status if required by project standards. Validate thermal management capabilities against the 225 mW dissipation limit.
Selection Notes
Select this component for designs requiring P-channel JFET characteristics in a small form factor. Consider the 30 V breakdown voltage for appropriate biasing conditions. Evaluate the thermal performance given the 225 mW power rating. Compare against N-channel alternatives if polarity requirements differ. Ensure the SOT-23 package fits within spatial constraints.
Part Context
This part belongs to the MMBF series of discrete JFETs from onsemi. The series includes both N-channel and P-channel variants designed for general-purpose use. These components are commonly used in audio and RF front-end stages where low noise and high input impedance are critical. The MMBF5460LT1 specifically addresses applications needing P-channel operation in compact packages.
Replacement Considerations
MMBF5457LT1 is an N-channel equivalent in the same series. Verify channel polarity compatibility before substitution. Other generic P-channel JFETs may require re-evaluation of pinout and electrical parameters.
