The SMCJ18CA is a high-reliability, bidirectional Transient Voltage Suppressor (TVS) diode manufactured by SMC Diodes. This device is specifically engineered to protect sensitive electronic equipment from voltage transients caused by inductive load switching, lightning strikes, and electrostatic discharge (ESD). With a standoff voltage of 18V and a peak pulse power dissipation of 1.5kW, the SMCJ18CA provides robust overvoltage protection. Its bidirectional configuration allows it to protect circuits from both positive and negative voltage transients. The SMC package offers excellent thermal performance and ease of board mounting. Supreme Components International is an authorised distributor of SMC Diodes, ensuring that you receive only genuine, high-quality components. This TVS diode is suitable for a wide range of applications, including I/O protection, VCC bus protection, and general circuit protection.
