The 1KSMB33CA is a 1000W transient voltage suppressor diode from Littelfuse, part of the 1KSMB series. It is designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient events. The device offers a reverse standoff voltage of 28.2V and a clamping voltage of 45.7V, with a peak pulse current capability of 21.9A. The response time is typically less than 1.0 picosecond from 0V to breakdown voltage minimum. It meets IEC 61000-4-2 ESD protection (30kV air, 30kV contact) and IEC 61000-4-4 EFT protection. The diode features a glass passivated chip junction, low incremental surge resistance, and excellent clamping capability. It is packaged in a surface mount DO-214AA (SMB) package, suitable for automated assembly. The operating temperature range is -55°C to 150°C, with a junction temperature range of -65°C to 150°C. Thermal resistance is 20°C/W junction to lead and 100°C/W junction to ambient. The part is halogen free and RoHS compliant (unverified), and meets MSL level 1. This device is ideal for general purpose transient protection in telecom, computer, industrial, and consumer electronics applications.
