SMBJ11A 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 12 V and a breakdown voltage range of 13.1 V to 15.6 V, with a maximum reverse leakage current of 10 µA at the rated working voltage. The diode offers fast response times of less than 1.0 picosecond and is housed in the DO-214AA (SMB) package, making it suitable for portable communications, computing, and video equipment. With a maximum peak current rating of 39.0 A and voltage clamping capability at 18.2 V, the SMBJ11A provides reliable protection against transient overvoltages in IEC 61000-4-2 ESD, IEC 61000-4-4 EFT, and IEC 61000-4-5 surge protection applications.
