STMicroelectronics STW14NK50Z: High-Performance N-Channel MOSFET for Demanding Applications
The STW14NK50Z from STMicroelectronics is a robust N-Channel Power MOSFET designed to deliver exceptional performance in high-voltage and high-current environments. With a drain-source voltage (Vdss) rating of 500V and continuous drain current capability of 14A at 25°C, this device is engineered for applications requiring reliable switching and power management in industrial, automotive, and consumer electronics sectors. Its advanced SuperMESH™ technology ensures minimal on-resistance (Rds(on)) of just 380mΩ at 6A and 10V Vgs, optimizing efficiency while reducing thermal stress.
Key Features and Technical Excellence
Built with ST's proprietary Power MOSFET technology, the STW14NK50Z combines high-voltage robustness with fast switching characteristics. The device's gate charge (Qg) of 92nC at 10V enables rapid transitions, minimizing switching losses in high-frequency operations. Its ±30V gate-source voltage (Vgs) tolerance provides design flexibility, while the 4.5V gate threshold voltage ensures compatibility with standard logic-level drivers. The integrated TO-247-3 package offers excellent thermal dissipation with a maximum power dissipation of 150W (Tc), maintaining performance stability across extreme operating temperatures (-55°C to 150°C).
Engineers will appreciate the device's inherent reliability features, including avalanche energy ratings and short-circuit withstand capability. The STW14NK50Z's 2000pF input capacitance (Ciss) at 25V Vds contributes to controlled switching dynamics, reducing electromagnetic interference (EMI) in power circuits. This makes it particularly suitable for motor drives, power supplies, and industrial automation systems where electromagnetic compatibility is critical.
