Operating the 3SK41 beyond these limits can cause permanent damage. Always design with a safety margin of at least 20-30% below these maximums. Drain-Source Voltage ( VDScap V sub cap D cap S end-sub
Designed to minimize internal noise, making it ideal for the front-end stages of sensitive receivers. Common Uses
. The isolated dual-gate architecture ensures excellent port-to-port isolation between the LO and RF circuits, minimizing harmonic distortion and noise cross-talk. Common Applications
The dual-gate configuration of the 3SK41 is its defining advantage for VHF applications: 3sk41 datasheet
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.

In the , the leads are arranged in a circle around the metal can. A small tab or a flattened area on the can indicates the Source lead. The Drain is typically the single lead that protrudes on the opposite side of the package. The two gate leads are located on the sides. It is strongly recommended to consult the original service manual for the specific equipment or a reliable datasheet when identifying the leads on an actual device. Operating the 3SK41 beyond these limits can cause
