Additional Details

The RK4936 features a low gate threshold voltage, typically around -1V to -3V, which allows it to be driven directly by low-voltage logic circuits. The maximum drain-source voltage (Vds) is typically -30V, and the continuous drain current (Id) is dependent on the specific package and operating conditions, but can be up to several Amperes. The device is typically available in a small surface mount package, such as a SOT-23 or similar, which allows for high-density board layouts. The low on-resistance (Rds(on)) is a key characteristic, minimizing power dissipation and enabling more efficient designs.
