VD55H1

VD55H1 is a high-performance power MOSFET manufactured by STMicroelectronics, designed for efficient switching applications in modern power management systems. It features a maximum drain-source voltage (VDS) of 55 V, making it suitable for medium-voltage circuits commonly found in consumer electronics, industrial control, and automotive systems. The device exhibits a low on-resistance (RDS(on)) of typically 12 mΩ at VGS = 10 V, ensuring minimal conduction losses and high energy efficiency—critical for reducing heat generation and improving system reliability. This MOSFET is constructed using advanced trench technology, which enhances its switching speed and reduces gate charge (Qg), enabling faster transitions between on and off states. Its optimized gate threshold voltage (Vth) ranges from 1.5 to 2.5 V, allowing compatibility with low-voltage control signals from microcontrollers or digital drivers. Additionally, the VD55H1 includes an integrated body diode with fast recovery characteristics, simplifying circuit design in synchronous rectification and buck converter topologies. The device is housed in a compact TO-220 package, offering excellent thermal performance through direct mounting on heatsinks, and supports both surface-mount and through-hole installation methods. It is rated for continuous drain current (ID) up to 13 A at 25°C ambient temperature, with peak pulse current capability exceeding 50 A, making it ideal for transient load handling in dynamic environments. VD55H1 is specifically tailored for use in DC-DC converters, motor drives, battery-powered devices, and LED lighting systems where high efficiency, small footprint, and robust thermal management are essential. Its rugged construction ensures reliable operation under harsh conditions, including high ambient temperatures and mechanical stress. Furthermore, the component complies with RoHS standards, reflecting STMicroelectronics’ commitment to environmentally responsible manufacturing practices. Engineers selecting this MOSFET benefit from its balance of performance, cost-effectiveness, and ease of integration into existing designs. Whether deployed in consumer power supplies or industrial automation equipment, the VD55H1 delivers consistent performance across a wide range of operating conditions, making it a versatile choice for power electronics applications requiring precision and durability.
