The SMBJ33A with 53.3V, 36.7V and 33V SMB TVS ROHS is a surface-mount, trimming, bidirectional Transient Voltage Suppressor (TVS) device manufactured by Me-Tech. It is designed to protect sensitive electronic equipment, including ports, from voltage surges. The SMBJ33A devices can absorb high surge energy and dissipate it quickly. They also provide flexibility via adjustable triggering and stand-off voltages. The SMBJ33A's features include high surge-rated performance, low capacitance, and high-current holding capabilities. It is RoHS compliant and available in a very small package (3.2 x 2mm) for space-saving applications.
