The CJSMBJ8.5CA is a unidirectional Transient Voltage Suppressor (TVS) diode from JSCJ (JCET). Supreme Components International is an authorised distributor, ensuring you receive genuine components. This TVS diode is designed to protect sensitive electronic equipment from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). Featuring a breakdown voltage of 8.5V, it effectively clamps voltage spikes to safe levels, preventing damage to downstream circuitry. The SMB package offers a compact footprint and excellent thermal performance. Ideal for use in power supplies, communication lines, and data interfaces, the CJSMBJ8.5CA provides reliable overvoltage protection in a variety of applications. Its unidirectional configuration makes it suitable for DC circuits where reverse voltage protection is not required.
