The ZS4753A-H is a unidirectional TVS diode manufactured by FORMOSA MICROSEMI. Supreme Components International is an authorised distributor of FORMOSA MICROSEMI components, ensuring you receive genuine and reliable parts. This diode is designed to protect sensitive electronic circuits from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching. With a typical reverse standoff voltage of 47V and a breakdown voltage of 53V, the ZS4753A-H effectively clamps overvoltage events, preventing damage to downstream components. It is housed in a compact DO-214AA (SMB) package, making it suitable for space-constrained applications. This TVS diode offers excellent surge handling capability and fast response time, making it an ideal choice for protecting I/O interfaces, power supplies, and data lines.
