The SMBG4752C/TR13 is a surface mount Transient Voltage Suppressor (TVS) diode manufactured by Microsemi Corporation. The 'C' suffix denotes that it is a bidirectional TVS diode, meaning it can protect circuits from voltage surges in both directions. It is designed to protect sensitive electronic equipment from voltage transients induced by lightning, electrostatic discharge (ESD), inductive load switching, and other transient voltage events. This TVS diode is packaged in an SMB (DO-214AA) package, making it suitable for automated assembly processes.
