Disclaimer: All specifications cited are based on historical datasheets. Electrical characteristics may vary between manufacturers (Hitachi vs. NEC). Always verify with the component in hand.
(Adjust resistor and choke values to meet the datasheet’s recommended bias point where gm is adequate and ID within limits.)

The 3SK41 features a classic four-lead . Looking at the bottom of the transistor (leads facing you, with the orientation tab pointing downward/clockwise), the pinout assignment follows the industry standard for dual-gate RF FETs: 3sk41 datasheet
The electrical characteristics define how the transistor performs under standard operating conditions ( DC Characteristics Gate-Source Cutoff Voltage (
As the 3SK41 is an older, often obsolete component, engineers and technicians may need replacements.

The is a classic N-channel dual-gate MOSFET primarily engineered by semiconductor pioneers like NEC , Hitachi, and Motorola. Encased in a rugged TO-72 (CAN-4) metal package , this specialized field-effect transistor is highly regarded for its low noise figure, fast switching capabilities, and dual-control configuration. This configuration makes it exceptionally well-suited for high-frequency radio frequency (RF) amplification, mixing, and automatic gain control (AGC) circuits.
Historically integrated into VHF/UHF television tuners, FM radio front-ends, and specialized receiver preamplifiers to boost weak airborne signals without drowning them in internal noise.
Typically housed in a micro-X or a similar small-form-factor RF package (e.g., metal can or ceramic cross-type) to minimize parasitic capacitance. 2. Pinout Configuration Always verify with the component in hand
