The 3SK41 is housed in a standard , offering robust RF shielding and thermal dissipation. The typical pin orientation, when looking at the bottom of the transistor lead layout with the alignment tab pointing downwards, is configured as follows: Pin 1: Source (S) & Case grounding. Pin 2: Drain (D) . Pin 3: Gate 2 ( G2cap G sub 2

While typically found in the CAN-4 metal package, the standard pin configuration for this type of dual-gate MOSFET includes: The output terminal. Source: The common terminal. Gate 1 ( G1cap G sub 1 ): Used for the primary input signal. Gate 2 ( G2cap G sub 2 ): Used for AGC or bias control to manage gain.
