Product introduction：
1. Product Introduction (STP7NB40-VB)
STP7NB40-VB is a high voltage N-type MOSFET in TO220 package, suitable for medium power and high efficiency switching applications. The maximum drain-source voltage (Vds) of this MOSFET is 500V, the maximum drain current (Id) is 13A, and it has a low on-resistance (Rds(on)), which is 660mΩ at Vgs=10V. This makes STP7NB40-VB widely used in medium to high power conversion, power management, switching power supplies and industrial drives, and can efficiently convert electrical energy, reduce losses and improve overall efficiency.
STP7NB40-VB uses Plannar technology, which is suitable for higher voltage applications and has good thermal stability and switching performance. Its gate-source voltage (Vgs) range is ±30V, which is compatible with a variety of drive circuits and is widely used in electronic devices that require medium and high voltage control. This MOSFET operates with low switching losses, making it ideal for high-frequency switching applications.
