The SMBJ100A is a transient voltage suppressor diode designed for surge and ESD protection in compact surface-mount applications. It features a working peak reverse voltage of 100 V, a breakdown voltage of 166 V, and a power dissipation capability of 600 watts, making it suitable for high-energy transient suppression. The device is housed in a DO-214AA (SMB) surface-mount package and offers fast response times of less than 5.0 picoseconds for bidirectional operation. The SMBJ100A is RoHS compliant and conforms to JEDEC standards, providing reliable protection against IEC 61000-4-2 ESD, IEC 61000-4-4 EFT, and IEC 61000-4-5 surge events. It is widely used in portable communications, computing, and video equipment where compact size and robust transient protection are essential.
