General-Purpose TVS Diode

SMBJ28CAActive

The SMBJ28CA TVS diode is a surge protection device based on the avalanche breakdown principle, specifically designed to protect sensitive electronic circuits from ESD (electrostatic discharge), surges, and other transient voltage disturbances.When a transient pulse exceeding its breakdown voltage appears in the circuit, the device quickly switches from a high-impedance state to a low-impedance state, diverting the overvoltage energy to the ground.
