NBA3N5573

The NBA3N5573 is a high-performance N-channel MOSFET manufactured by onsemi, designed for efficient power management in demanding applications. It features a low on-resistance of 1.8 mΩ at VGS = 10 V, enabling minimal conduction losses and improved energy efficiency. The device operates with a maximum drain-source voltage (VDS) of 60 V, making it suitable for medium-voltage switching circuits commonly found in industrial, automotive, and consumer electronics. This MOSFET is optimized for fast switching speeds, supported by a low gate charge (QG = 42 nC), which reduces switching losses and enhances system performance in high-frequency applications such as DC-DC converters and motor drives. Its robust construction includes a TO-220 package that ensures reliable thermal dissipation and mechanical stability under continuous operation. The NBA3N5573 incorporates advanced trench technology to improve current handling capability while maintaining a compact footprint. It exhibits excellent avalanche ruggedness and safe operating area (SOA) characteristics, providing protection against overcurrent and transient voltage conditions—critical for reliability in harsh environments like automotive powertrains or industrial automation systems. Designed for high-efficiency power conversion, the device supports applications requiring precise control and minimal heat generation, including LED lighting drivers, battery management systems, and power supplies for computing equipment. Its low threshold voltage (Vth = 1.0 V typical) allows easy drive from logic-level signals, simplifying integration with microcontrollers and digital control circuits. The component is fully compliant with RoHS standards and is built for long-term operational stability, even under high ambient temperatures. onsemi’s stringent quality control processes ensure consistent performance across production batches, making the NBA3N5573 a trusted choice for engineers seeking reliable, high-efficiency switching solutions in modern electronic designs.
