The SMAJ19A is a surface-mount Transient Voltage Suppressor (TVS) diode manufactured by JSCJ (JCET). Supreme Components International is an authorised distributor of this component. This diode is designed to protect sensitive electronic circuits from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). It features a standoff voltage of 19V and a peak pulse power dissipation of 400W. The SMAJ19A is housed in a compact SMA (DO-214AC) package, making it suitable for high-density PCB layouts. Its fast response time and low clamping voltage ensure effective protection for downstream components. This TVS diode is widely used in telecommunications, industrial equipment, and consumer electronics applications where reliable overvoltage protection is critical.
