The ZGFM1043B-MST-Q1-H is a high-performance, unidirectional TVS diode manufactured by FORMOSA MICROSEMI. Designed to protect sensitive electronic circuits from voltage transients induced by electrostatic discharge (ESD), electrical fast transients (EFT), and lightning, this diode offers a robust and reliable solution. With a breakdown voltage of 43V, it effectively clamps transient voltages to safe levels, preventing damage to downstream components. The compact SOD-323 package makes it suitable for high-density PCB layouts. Supreme Components International is an authorised distributor of FORMOSA MICROSEMI components, ensuring you receive genuine products with full traceability and support. This TVS diode is ideal for automotive, industrial, and consumer electronics applications requiring reliable surge protection.
