The SMBJ33A is a transient voltage suppressor diode (TVS) designed by Lite-On. It is a unidirectional "stand-off" voltage device designed for protection against surges, transients, and electrostatic discharges. The SMBJ33A has a 5.0kW peak pulse power dissipation rating, 5.0V standoff voltage, and a working voltage of up to 33V. It is RoHS compliant and capable of handling a wide range of current levels. The SMB package is a high-reliability, surface-mount package type, which provides excellent thermal performance.
