The ZGFM5933B-H is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Formosa Microsemi. This diode is specifically designed to protect sensitive electronic components from voltage transients induced by electrostatic discharge (ESD), electrical fast transients (EFT), and lightning. With a breakdown voltage of 5V, the ZGFM5933B-H effectively clamps overvoltage events, preventing damage to downstream circuitry. Its unidirectional configuration allows it to suppress positive voltage transients. 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 and reliable products. This TVS diode is ideal for applications such as data lines, I/O ports, and power supplies.
