Technical Specifications:

The 2SK3651-01R generally features a drain-source voltage (VDSS) of 900V, allowing it to be used in high-voltage applications. The continuous drain current (ID) is typically rated around 3A, and the pulsed drain current (IDM) can reach significantly higher values. The on-resistance (RDS(on)) is approximately 3.0 ohms at a gate-source voltage (VGS) of 10V. The gate threshold voltage (VGS(th)) is typically between 2V and 4V. This MOSFET is housed in a TO-220 package, which provides good thermal performance. It is designed to operate within a temperature range of -55°C to +150°C.

The low gate charge (Qg) contributes to faster switching speeds and reduces switching losses. The device also features good avalanche ruggedness, which protects against voltage transients. The TO-220 package allows for easy mounting to a heat sink, ensuring effective heat dissipation. The 2SK3651-01R is well-suited for applications that require a combination of high voltage, moderate current, and efficient switching.
