The SMBJ45A is a Transient Voltage Suppressor (TVS) diode manufactured by JSCJ (JCET). Supreme Components International is an authorised distributor of JSCJ components, ensuring you receive genuine parts. This diode is designed to protect sensitive electronic circuits from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). With a reverse standoff voltage of 45V and a breakdown voltage of 66V, the SMBJ45A effectively clamps overvoltage events, preventing damage to downstream components. Its SMB package allows for efficient heat dissipation and easy board mounting. This TVS diode is suitable for a wide range of applications, including industrial equipment, automotive electronics, and consumer devices, providing robust and reliable protection against voltage surges.
