The SMAJ40CA is a high-reliability, 400W transient voltage suppressor (TVS) diode manufactured by JSCJ (JCET). Designed for bidirectional protection, this device effectively clamps voltage spikes at 40V, safeguarding downstream components from damage due to electrostatic discharge (ESD), electrical fast transients (EFT), and lightning surges. Housed in a compact SMA package, the SMAJ40CA is ideal for surface-mount applications where space is limited. Supreme Components International is an authorised distributor of JSCJ (JCET) components, ensuring you receive genuine, high-quality products. This TVS diode is suitable for a wide range of applications, including automotive, industrial, and consumer electronics, providing robust and reliable overvoltage protection.
