The ZS4740A-Q1-H is a high-performance Transient Voltage Suppressor (TVS) diode manufactured by Formosa Microsemi. Supreme Components International is an authorised distributor of Formosa Microsemi components. This unidirectional TVS diode is designed to protect sensitive electronic circuits from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). With a power dissipation rating of 400W and a breakdown voltage of 47V, the ZS4740A-Q1-H offers robust protection in a compact DO-214AC (SMA) package. Its unidirectional configuration ensures optimal performance in applications where reverse voltage protection is not required. This TVS diode is ideal for use in automotive, industrial, and consumer electronics applications where reliable surge protection is critical.
