The ZGFM3043B-H is a TVS (Transient Voltage Suppressor) Diode manufactured by FORMOSA MICROSEMI. Supreme Components International is an authorised distributor of FORMOSA MICROSEMI components. This diode is designed to protect sensitive electronic circuits from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching. With a reverse standoff voltage of 30V and a peak pulse current of 43A, the ZGFM3043B-H offers reliable overvoltage protection. It comes in a compact DO-214AA (SMB) package, making it suitable for various applications where space is a constraint. This TVS diode is ideal for use in power supplies, communication equipment, and industrial control systems. Its fast response time and low clamping voltage ensure effective protection against transient events, enhancing the overall reliability and longevity of your electronic devices.
