The HSBA4903 is a Dual-Channel Power MOSFET Transistor designed and manufactured by the well-known company Huashuo. This MOSFET comes in a PRPAK (5x6) package, which is a smaller, more efficient way to package multiple power transistors together into a single device.The HSBA4903 has two channels, one N-Channel and one P-Channel, each rated at 40V and 35W. It also has built-in overvoltage protection and Zener breakdown protection to ensure reliable performance. The HSBA4903 is RoHS compliant and safe for use in a variety of industrial and engineering applications.
