1. **SW4N70D-VB Product Introduction**
SW4N70D-VB is a high voltage N-Channel MOSFET in TO251 package, suitable for power management and power conversion applications. It has a drain-source voltage (VDS) of 700V, can withstand higher voltage loads, and is suitable for use in environments that require high voltage tolerance. The maximum drain current (ID) of this MOSFET is 4A, and the threshold voltage (Vth) is 3.5V, which can stably drive and control the switch. SW4N70D-VB adopts **Plannar technology** to optimize thermal performance and reliability, ensuring low temperature rise and stability of the MOSFET during operation. Its on-resistance (RDS(ON)) is 2600mΩ at VGS=10V. Although it is relatively high, it can still be used in high-voltage applications with lower power and medium current.
