The SMAJ90A is a surface-mount Transient Voltage Suppressor (TVS) Diode manufactured by JSCJ (JCET). Supreme Components International is an authorised distributor of JSCJ components. 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 reverse standoff voltage of 90V and a peak pulse power dissipation of 400W. The SMAJ90A 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 against overvoltage events. Applications include telecommunications, industrial equipment, and consumer electronics.
