The 3.0SMI12A is a high-power Surface Mount TVS (Transient Voltage Suppressor) Diode manufactured by SMC DIODES. Supreme Components International is an authorised distributor of SMC DIODES components. This diode is designed to protect sensitive electronic circuits from voltage transients caused by electrostatic discharge (ESD), electrical fast transients (EFT), and lightning. With a peak pulse power dissipation of 3000W and a reverse standoff voltage of 12V, the 3.0SMI12A offers robust protection in a compact surface mount package. It is suitable for use in telecommunications, industrial control, consumer electronics, and automotive applications where reliable surge protection is critical. Its fast response time and low clamping voltage ensure effective protection of downstream components.
