STD14NM50N-VB Product Introduction
STD14NM50N-VB is a high-voltage N-channel power MOSFET in TO-252 package. It has a drain-source voltage (VDS) of 500V and a gate-source voltage (VGS) of ±30V, suitable for high-voltage power supply applications. Its turn-on voltage (Vth) is 3.5V, ensuring low-voltage drive, and has an on-resistance of 290mΩ (RDS(ON) @ VGS=10V), which effectively reduces power loss. This MOSFET adopts SJ_Multi-EPI technology, which improves the voltage resistance and can provide higher switching speed and lower conduction loss. Its maximum current is 14A, suitable for electronic devices that require high voltage and low power loss, such as switching power supplies, industrial control, home appliances, etc.
