SMBJ48CA is a bidirectional transient voltage suppressor diode designed for surge and ESD protection in portable communications, computing, and video equipment. It features a working peak reverse voltage of 48 V with a breakdown voltage of approximately 58.9 V, housed in a compact DO-214AA (SMB) surface mount package. The device offers fast response times of less than 5.0 picoseconds and is rated for 600 watts peak power dissipation, providing robust protection against transient overvoltage events. It meets IEC 61000-4-2 ESD (Level 4), IEC 61000-4-4 EFT, and IEC 61000-4-5 Surge standards, making it ideal for protecting sensitive electronic circuits in consumer and industrial applications.
