High-Performance STP4NK80Z MOSFET for Demanding Power Applications
Engineered for reliability and efficiency, the STP4NK80Z MOSFET from STMicroelectronics represents the cutting-edge of power semiconductor technology. This N-channel SuperMESH™ device combines robust 800V breakdown voltage with 3A continuous drain current capabilities, making it ideal for high-voltage switching applications where performance and durability are critical. Designed in the industry-standard TO-220AB package, this component offers exceptional thermal management and mechanical stability for demanding industrial environments.
Advanced SuperMESH™ Technology
At the heart of the STP4NK80Z lies STMicroelectronics' proprietary SuperMESH™ technology, which delivers an optimal balance between on-state resistance and switching performance. With a maximum RDS(on) of just 3.5Ω at 1.5A and 10V gate-source voltage, this MOSFET minimizes conduction losses while maintaining fast switching characteristics. The advanced trench gate structure enables superior gate charge control (22.5nC max @ 10V), reducing switching losses in high-frequency applications up to 150°C operating temperature.
Engineers will appreciate the device's comprehensive protection features, including ±30V gate voltage tolerance and integrated thermal shutdown capabilities. The 80W (Tc) power dissipation rating ensures reliable operation in challenging thermal conditions, while the -55°C to 150°C operating temperature range accommodates extreme environmental requirements.
