The SMAJ43CA is a surface-mount Transient Voltage Suppressor (TVS) diode manufactured by JSCJ (JCET). Supreme Components International is an authorised distributor of JSCJ components, ensuring you receive genuine parts. This diode is designed to protect sensitive electronic circuits from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching. It features a 43V reverse breakdown voltage (Vbr) and a power dissipation of 400W. The SMAJ43CA is commonly used in applications such as telecommunications, industrial equipment, and consumer electronics to enhance system reliability and prevent damage from overvoltage events. Its compact SMA package makes it suitable for high-density circuit board designs.
