Back to previous pageProduct introduction：
1. **SW4N65D-VB Product Introduction**
SW4N65D-VB is a high voltage N-Channel MOSFET in TO251 package, designed for medium and high voltage power management applications. With a drain-source voltage (VDS) of 650V, this MOSFET can withstand high voltage stress and has a maximum drain current (ID) of 4A. Its threshold voltage (Vth) is 3.5V, ensuring stable switching performance. SW4N65D-VB adopts **Plannar technology**, which ensures good thermal performance and reliability by optimizing the chip structure. Although its on-resistance (RDS(ON)) is 2200mΩ@VGS=10V, which is relatively high, it is still suitable for some applications that do not require high switching speed, especially in applications where low current and voltage tolerance are not particularly stringent. This MOSFET is suitable for power conversion, power management and low power drive systems.
