STW56N65DM2

STW56N65DM2 is a high-performance N-channel MOSFET manufactured by STMicroelectronics, designed for efficient power switching applications. It features a maximum drain-source voltage (VDS) of 650 V, making it suitable for high-voltage circuits such as industrial power supplies, motor drives, and inverters. The device offers a low on-resistance (RDS(on) = 380 mΩ at VGS = 10 V), ensuring minimal conduction losses and high energy efficiency in continuous operation. The transistor is built using advanced trench technology, which enhances thermal performance and reduces switching losses. Its gate charge (QG) is optimized to support fast switching speeds while maintaining robust gate drive requirements—ideal for high-frequency switching applications like switch-mode power supplies (SMPS) and DC-DC converters. The device also includes an integrated anti-parallel diode, simplifying circuit design and improving reliability in inductive load scenarios. Packaged in a TO-220AB form factor, the STW56N65DM2 provides excellent thermal dissipation and mechanical durability, enabling stable operation under demanding conditions. It is rated for a maximum junction temperature of 175°C, allowing reliable performance in environments with elevated ambient temperatures. Additionally, the component complies with RoHS standards, reflecting its compliance with environmental regulations. This MOSFET is particularly well-suited for applications requiring high efficiency and compact design, including solar inverters, battery charging systems, and industrial automation equipment. Its robust construction supports safe operation under transient overcurrent and short-circuit conditions, thanks to a well-defined safe operating area (SOA). The device’s high avalanche ruggedness further ensures resilience against voltage spikes commonly found in power electronics systems. Engineers benefit from the STW56N65DM2’s consistent electrical characteristics across temperature and production batches, reducing the need for extensive testing during system integration. With its combination of low RDS(on), high voltage tolerance, and thermal stability, this MOSFET delivers a compelling solution for modern power management challenges in both consumer and industrial markets.
