The SMBJ300CA is a high-performance Transient Voltage Suppressor (TVS) Diode manufactured by SMC Diodes. As a bidirectional TVS diode, it provides symmetrical voltage protection, making it suitable for AC and DC applications. It features a standoff voltage of 300V and a peak pulse power dissipation of 600W, effectively clamping transient voltages to protect downstream circuitry from damage caused by electrostatic discharge (ESD), electrical fast transients (EFT), and lightning surges. This SMB packaged diode is designed for surface mounting, offering ease of integration into printed circuit boards. Supreme Components International is an authorized distributor of SMC Diodes, guaranteeing the authenticity and quality of this TVS diode. Ideal for use in telecommunications, industrial equipment, and consumer electronics.
