SMBJ18CA product description

         SMBJ18CA is a bidirectional TVS diode produced by Bourns Inc., capable of suppressing transient overvoltages up to 29.2V at an operating voltage of 18V, protecting power lines and signal lines from damage. It has the advantages of low leakage current, high peak pulse power, fast response, wide operating temperature range and environmental performance.

SMBJ18CA product application

         1. Power management: SMBJ18CA can be used for the input of power management chips, converters, voltage regulators and other power equipment to protect them from transient overvoltage damage such as lightning strikes, electrostatic discharges, and load conversions.

         2. Communication equipment: SMBJ18CA can be used in sensitive parts such as data lines, signal lines, and antenna ports in communication equipment to protect them from transient overvoltages such as radio frequency interference, inductive coupling, and switching noise.

         3. Industrial control: SMBJ18CA can be used for key components such as sensors, actuators, and bus interfaces in industrial control equipment to protect them from transient overvoltage hazards such as high-voltage shocks, ground loops, and surge currents.
