SMBJ58A is a transient voltage suppressor diode designed for surge and ESD protection in compact surface-mount applications. It features a working peak reverse voltage of 58V with a breakdown voltage range of 66.7V to 71.2V, providing reliable protection against transient overvoltage events. The device is housed in a DO-214AA (SMB) surface-mount package and offers fast response times typical of the SMBJ series, making it suitable for protecting sensitive electronic circuits in portable communications, computing, and video equipment. With its 600-watt power dissipation capability and compliance with IEC 61000-4-2 ESD, IEC 61000-4-4 EFT, and IEC 61000-4-5 Surge standards, the SMBJ58A provides robust protection for industrial and consumer applications requiring high-reliability transient suppression.
