The ZGFM3012B-H is a Transient Voltage Suppressor (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 TVS diode is specifically designed to protect sensitive electronic circuits from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching. With a power dissipation rating of 3000W and a breakdown voltage of 12V, the ZGFM3012B-H offers robust protection against overvoltage conditions. Its unidirectional configuration allows it to effectively clamp positive voltage spikes, preventing damage to downstream components. The DO-214AB (SMC) package provides excellent thermal performance and is suitable for surface mount assembly. Ideal for use in power supplies, communication equipment, and industrial control systems, the ZGFM3012B-H ensures the reliability and longevity of your electronic designs.
