SMBJ11CA is a bidirectional transient voltage suppressor diode designed for surge and ESD protection in compact surface-mount applications. It features a working peak reverse voltage of 12 V, with a breakdown voltage range of 13.1 V to 15.6 V, and is housed in the DO-214AA (SMB) package format. The device exhibits fast response times of less than 5.0 picoseconds and provides voltage clamping at 18.2 V with a maximum peak current capability of 39.0 A. This TVS diode is ideal for protecting sensitive electronics in portable communications, computing, and video equipment against transient overvoltage events including ESD (IEC 61000-4-2), electrical fast transients (IEC 61000-4-4), and surge conditions (IEC 61000-4-5).
