The SMBJ20A is a unidirectional transient voltage suppressor diode designed for surge and ESD protection in compact surface-mount applications. This device features a working peak reverse voltage of 20 V, a breakdown voltage range of 22.2 to 24.5 V, and a maximum reverse leakage current of 10 µA at rated voltage. The SMBJ20A delivers fast response times of less than 1.0 picosecond and is housed in the compact DO-214AA (SMB) surface-mount package, making it ideal for portable communications, computing, and video equipment. It provides robust protection against transient overvoltages and is RoHS compliant, meeting IEC 61000-4-2 ESD, IEC 61000-4-4 EFT, and IEC 61000-4-5 Surge standards.
