SMBJ45CA is a bidirectional transient voltage suppressor diode designed for surge and ESD protection in portable communications, computing, and video equipment. This device features a working peak reverse voltage of 45 V, a breakdown voltage range of 50.3 V to 55.3 V, and is housed in a compact DO-214AA (SMB) surface mount package. The diode exhibits fast response times of less than 5.0 picoseconds and provides voltage clamping at 77.7 V with a maximum peak current rating of 8.3 A. With a power dissipation capability of 600 watts and RoHS compliance, the SMBJ45CA is ideal for protecting sensitive electronics against transient overvoltage events in accordance with IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (Surge) standards.
