The ER3J is a fast recovery rectifier diode manufactured by GoodWork. It is an SMC (DO-214AB) diode, constructed in a plastic case with an epoxy coating for increased moisture and heat resistance. The diode features a reverse voltage of 75V, a forward current of 3 Amps, and a very fast recovery time of 4.25ns. It is also RoHS compliant which means it meets the restrictions set on the use of hazardous substances in the manufacture of electric and electronic equipment. The ER3J is well-suited for use in signal and power rectification circuitry, such as in power conversion circuits, inverters, and/or motor drives.
