3sk41 Datasheet Link

Understanding the absolute maximum ratings and electrical characteristics is critical for replacing or designing with this vintage active component. When operating near high-frequency limits, tracking thermal limits and breakdown voltages safeguards the device from premature failure. Key Maximum Ratings & Electrical Characteristics 250 mW Gate-Source Breakdown Voltage (

: In many circuits, it can be part of a broader series of "3SK" transistors (like the 3SK35 or 3SK40) depending on the specific voltage and gain requirements of your project. Jotrin Electronics Are you looking to use this for a new RF design 3SK41 - NEC/HITACHI/MOTOROLA - Jotrin

(metal can) package, which provides excellent shielding for RF stability. High Gain & Low Noise 3sk41 datasheet

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:

Dual-gate MOSFETs like the 3SK41 are unique because they decouple input and output capacitance. This engineering feat drastically cuts down the Miller effect, allowing stable, high-gain operation well into the VHF and UHF bands without requiring complex neutralization circuits. Technical Specifications Overview Jotrin Electronics Are you looking to use this

Do you prefer components, or are surface-mount (SMD) alternatives acceptable?

Because the 3SK41 is a depletion-mode MOSFET, it is "normally on" with VGS=0V. A multimeter in diode mode will not test it properly. Here is how to test from the suggestions: This engineering feat drastically cuts down the Miller

Summary: the 3SK41 is an N‑channel dual‑gate MOSFET (small RF/low‑power device in a CAN/TO‑style metal can) used historically in VHF/UHF tuner and RF front‑end circuits. Below I break down what a datasheet for this part usually contains, explain the key specs, show how they affect circuit behavior, give practical tips for selection, testing, PCB layout and replacement/cross‑reference, and include simple application examples.
