3sk41 Datasheet -

The 3SK41 comes in a metal can package, often designated as TO-72 or CAN-4, which is crucial for radio frequency shielding and heat dissipation. Source (S) Gate 1 (G1) Gate 2 (G2)

Used in receiver RF amplifiers and balanced mixer stages, particularly in legacy radio gear. Equivalents: If the 3SK41 is unavailable, common substitutes include the 3SK40, 2SK701, 2SK702, and 2SK703 Legacy Availability:

The second gate acts as a shield between the input gate and the drain, drastically reducing internal feedback (Miller effect). 3sk41 datasheet

The dual-gate architecture allows for clean, low-distortion frequency conversion. Core Strengths

By placing Gate 2 structurally between Gate 1 and the Drain, the device creates an internal cascade configuration. This drastically minimizes the internal feedback capacitance ( Crsscap C sub r s s end-sub The 3SK41 comes in a metal can package,

The dual-gate structure of the 3SK41 provides significant advantages in RF signal processing. Why Dual-Gate?

: Minimizes loading on the preceding stage. Why Dual-Gate

: Typically supplied in a CAN-4 (TO-72) metal package, providing excellent shielding.

implementation. By varying the voltage on Gate 2, you can control the amplifier's gain without significantly affecting the input impedance or tuning, which is a major advantage in radio receiver design. Censtry.com Sourcing & Replacements

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 (

Due to its high-speed switching capabilities, low noise figure, and linear transfer traits, the 3SK41 is commonly found in:
