ONSEMI GBU8M Bridge Rectifier Diode, Single Phase, 1kV, 8A

The ONSEMI GBU8M is a robust, single-phase bridge rectifier diode designed for general-purpose power conversion. Featuring a moulded plastic construction with a glass-passivated junction, it ensures reliable performance and stable operation across a range of applications, particularly where mains rectification is required. Its design prioritises durability and consistent electrical characteristics.

This rectifier is capable of handling an average forward current of 8A and a repetitive peak reverse voltage of 1kV, making it suitable for medium-power circuits. With a low forward voltage drop of a maximum of 1V, it helps to minimise power loss and improve overall system efficiency. The device is housed in a through-hole mountable SIP (Single In-line Package) case style for straightforward PCB integration.
