Datasheet |best| - 3sk41

The 3SK41 usually follows the standard TO-72 four-lead configuration. Looking from the bottom (pins facing you), the leads are typically arranged as follows:

The 3SK41 remains a respected component for RF enthusiasts due to its low noise and stable gain. Whether you are repairing a vintage transceiver or building a custom VHF pre-amplifier, understanding the is the first step toward a successful build. Always ensure proper ESD (Electrostatic Discharge) precautions when handling these MOSFETs, as the gates are highly sensitive to static electricity.

): Typically ranges between 10 to 20 mS (millisiemens), indicating high sensitivity. Generally around 5.0 pF. Reverse Transfer Capacitance ( Crsscap C r s s 3sk41 datasheet

Modern silicon N-channel dual-gate MOSFETs (though they often come in SOT packages).

Minimizes loading on preceding stages. 2. Technical Specifications (Absolute Maximum Ratings) The 3SK41 usually follows the standard TO-72 four-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.

Typically used for AGC or as the local oscillator input in mixers. Gate 1 (G1): The primary signal input lead. Reverse Transfer Capacitance ( Crsscap C r s

Provides significant signal boost in the VHF range.
