3sk41 — Datasheet

The 3SK41 is largely considered an . It is rarely used in new designs today, as it has been replaced by more modern surface-mount devices (SMD) like the BF998 or high-speed Gallium Arsenide (GaAs) FETs. However, it remains highly sought after by hobbyists for repairing vintage ham radios, scanners, and TV tuners.

The "dual-gate" design is the defining feature of the 3SK41, allowing it to excel in two specific areas: 3sk41 datasheet

Known for high gain, low noise figure, and high transconductance. Typical Uses: VHF/UHF tuners and receiver front-ends. Common Information Found in 3SK41 Datasheets: Manufacturer: NEC/Hitachi/Motorola Package Type: CAN-4 / Metal Can The 3SK41 is largely considered an

: Provides various versions of the PDF datasheet from multiple manufacturers. The "dual-gate" design is the defining feature of

The is a high-performance Silicon N-Channel Dual Gate MOSFET typically used in high-frequency (RF) and microwave applications. It is manufactured by companies including NEC, Hitachi, and Motorola and is often housed in a CAN-4 (similar to TO-72) metal package. Key Features & Applications:

If you are searching for the , you are likely either repairing a classic tuner from the 1980s–1990s, designing a low-noise front-end for a receiver, or trying to cross-reference a replacement. This article serves as a detailed datasheet analysis, covering absolute maximum ratings, electrical characteristics, pin configurations, application circuits, and modern alternatives.
