The provides critical technical specifications for an legacy N-channel dual-gate Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) . Originally manufactured by Japanese and global semiconductor pioneers including NEC, Hitachi, and Motorola , the 3SK41 was built in a TO-72 (CAN-4) metal package . It was engineering-optimized for high-frequency RF amplification, fast switching, and low noise figures in consumer and industrial communication tuners.
Typically connected to the system ground or a self-biasing resistor network. The substrate is often tied to this lead to minimize RF feedback.

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 The substrate is often tied to this lead
When working with a 3SK41, remember that MOSFETs are highly sensitive to . Even a small spark from your fingertip can puncture the thin oxide layer of the gates, destroying the transistor. Always use an anti-static wrist strap and a grounded soldering iron when handling these components.
The dual-gate configuration of the 3SK41 is its defining advantage for VHF applications:
