Acting as the first stage of amplification.
When reviewing the 3SK41 datasheet, the absolute maximum ratings are critical to prevent component failure. Operating beyond these limits can cause permanent damage. Drain-Source Voltage Gate 1-Source Voltage Gate 2-Source Voltage Drain Current Total Power Dissipation Storage Temperature -55 to +150 3. Electrical Characteristics Under typical operating conditions (usually at ), the 3SK41 exhibits the following performance: Forward Transfer Admittance (
The is a classic N-channel dual-gate MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) that has long been a staple in high-frequency applications . Primarily designed for VHF (Very High Frequency) amplifiers and mixers, it remains a point of interest for hobbyists, vintage radio restorers, and engineers working with legacy RF circuits. 3sk41 datasheet
Facilitates easy Automatic Gain Control (AGC) and mixing functions.

Typically used for AGC or as the local oscillator input in mixers. Gate 1 (G1): The primary signal input lead.
Because the 3SK41 is an older component, it can sometimes be difficult to source. If you cannot find an original, consider these common substitutes: Very similar characteristics, often interchangeable. Facilitates easy Automatic Gain Control (AGC) and mixing
Often tied together to provide grounding and shielding. Drain (D): The output lead.
The 3SK41 is housed in a standard TO-72 metal can package. Its dual-gate construction is its defining feature, allowing for superior gain control and reduced feedback capacitance compared to single-gate FETs. Ideal for front-end RF amplification.
(Note: Always verify the pinout with the specific manufacturer’s marking, as some variations exist.) 5. Common Applications
