The SMCJ18A is a high-performance, unidirectional Transient Voltage Suppressor (TVS) diode manufactured by SMC DIODES. As an authorized distributor, Supreme Components International offers this diode, designed to protect sensitive electronic equipment from voltage transients. With a breakdown voltage of 18V and a peak pulse power dissipation of 1500W, the SMCJ18A effectively clamps transient voltages, preventing damage to downstream components. Its unidirectional configuration makes it suitable for DC circuits. The SMC package provides excellent thermal performance and ease of mounting. This TVS diode is ideal for applications requiring robust overvoltage protection, such as power supplies, communication equipment, and industrial control systems.
