Technical Specifications:

The 2SK2809-01MR typically features a drain-source voltage (VDSS) rating of 900V, enabling its use in high-voltage applications. The continuous drain current (ID) is rated at approximately 5A, while the pulsed drain current (IDM) can reach significantly higher values. The on-resistance (RDS(on)) is typically around 2.5 ohms at a gate-source voltage (VGS) of 10V. The gate threshold voltage (VGS(th)) is usually between 2V and 4V. This MOSFET is available in a TO-220F package, providing good thermal performance. It is designed to operate over a wide temperature range, typically from -55°C to +150°C.

The low gate charge (Qg) facilitates faster switching speeds and reduces switching losses. The device also exhibits good avalanche ruggedness, enhancing its ability to withstand transient voltage spikes. The isolated package option simplifies heat sink mounting and reduces the risk of short circuits. The 2SK2809-01MR is well-suited for applications demanding a combination of high voltage, moderate current, and efficient switching performance.
