The N Channel MOSFET STP7NK40Z from STMicroelectronics features a maximum drain-source voltage of 400V and a continuous drain current rating of 5.4A. It is housed in a TO-220 package, making it suitable for through-hole mounting applications. The device has a typical on-resistance (RDS(on)) of 0.85 ohms when tested at a gate-source voltage of 10V. It is designed for high-speed switching applications and is ideal for use in off-line power supplies, adapters, and power factor correction (PFC) circuits. The MOSFET includes built-in gate-source Zener diodes for enhanced ESD protection and transient voltage absorption, eliminating the need for external components. The device is also 100% avalanche tested, ensuring reliability in demanding conditions.
