Overview
The Panasonic 2SK3426 is a silicon N-channel junction field-effect transistor designed for low-frequency impedance conversion and electret capacitor microphone applications. It operates within an ambient temperature range of -20°C to +80°C and features a maximum power dissipation of 100 mW. The device provides a drain-source voltage rating of 20 V and supports a drain current up to 2 mA. Key electrical characteristics include a mutual conductance ranging from 660 µS to 1,600 µS at 1 kHz, with a typical noise voltage of 10 µV. It utilizes the SSSMini3-F1 package.
Feature Summary
- High mutual conductance suitable for signal amplification
- Low noise voltage performance for sensitive audio circuits
- Optimized for low-frequency impedance conversion tasks
Applications
- Electret capacitor microphone pre-amplifiers
- Low-frequency impedance conversion stages
- General-purpose small-signal amplification
Procurement Notes
Verify component authenticity through authorized distributors or official Panasonic channels. Confirm RoHS compliance status and check the manufacturer's website for current lifecycle information regarding maintenance or discontinuation status before finalizing procurement plans.
Selection Notes
Select this component when low noise and high mutual conductance are required for low-frequency signal processing. Ensure the design accommodates the 100 mW power dissipation limit and verify that the SSSMini3-F1 package dimensions fit the target PCB layout constraints.
Part Context
This part belongs to the Panasonic Silicon Junction FETs (Small Signal) series. It is specifically engineered for applications requiring stable performance in low-frequency environments, such as audio input stages where signal integrity and minimal noise introduction are critical design parameters.
Replacement Considerations
Consult the official Panasonic semiconductor catalog for verified replacement options. Cross-compatibility should be validated against pinout configurations, absolute maximum ratings, and specific electrical characteristics like mutual conductance and noise voltage.
