SW18N50D-VB TO247 Product details
Back to previous pageProduct introduction：
1. Product Introduction:
The SW18N50D-VB is an N-channel MOSFET in a TO247 package designed for high voltage switching applications. It has a drain-to-source voltage (VDS) of 500V and is suitable for power control and switching circuits that require high voltage carrying. Its maximum drain current (ID) can reach 18A, which is suitable for high-efficiency operation in power-intensive applications. The SW18N50D-VB uses SJ_Multi-EPI technology to provide low on-resistance (RDS(ON) = 240mΩ), which helps reduce conduction losses and improve the efficiency of the power system. Its switching threshold voltage (Vth) is 3.5V, which allows it to be turned on at a lower gate voltage, making it suitable for high-frequency switching circuits that require fast response.
