STW14NM50FD: A High-Voltage Power MOSFET for Robust Applications
The STW14NM50FD is a high-voltage Power MOSFET designed for demanding applications that require reliability, efficiency, and safety. This advanced power transistor is part of the STMicroelectronics family of N-channel SuperMESH? MOSFETs that offer outstanding performance and ruggedness in a wide range of industrial and automotive systems.
With a maximum voltage rating of 500V and a drain current capability of 14A, the STW14NM50FD MOSFET can handle high-power loads with low on-resistance (0.48?) and fast switching times. This makes it ideal for motor control, power supplies, inverters, welding equipment, lighting, and other high-voltage applications that require precise control and high efficiency.
The STW14NM50FD features a low gate charge (30nC), which reduces switching losses and improves thermal performance. The device also includes an integrated fast-recovery diode (FRD) that limits the reverse recovery charge and improves switching behavior. Moreover, the MOSFET is designed with a Kelvin-source connection that enhances gate-drive accuracy and reduces gate-to-source ringing, which can cause voltage spikes and electromagnetic interference (EMI).
One of the key benefits of the STW14NM50FD MOSFET is its robustness against transient overvoltage, avalanche breakdown, and thermal stress. The device is capable of handling high-energy pulses and surges without degradation or failure, thanks to its low gate capacitance and high avalanche energy rating. Additionally, the MOSFET has a junction-to-ambient thermal resistance of 62°C/W, which enables it to dissipate heat effectively and prevent thermal runaway.
The STW14NM50FD is housed in a TO-247 package that provides excellent thermal conductivity and electrical isolation. The package is also RoHS compliant and halogen-free, making it environmentally friendly. The MOSFET is rated for operation between -55°C and 150°C, which makes it suitable for harsh environments and industrial applications.
To maximize the performance and reliability of the STW14NM50FD MOSFET, it is important to use proper PCB layout, gate-drive circuitry, and thermal management. STMicroelectronics provides a wide range of technical documents, application notes, and evaluation boards to help designers use the MOSFET effectively and efficiently.
In summary, the STW14NM50FD is a versatile high-voltage Power MOSFET that offers robustness, efficiency, and safety in demanding applications. With its low on-resistance, fast switching, and low capacitance, this MOSFET is perfect for motor drives, power converters, and other power electronics systems that require high performance and durability.
