The SMAJ45A 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 45V and a breakdown voltage of 49.9V. The SMAJ45A is housed in a compact SMA (DO-214AC) package, making it suitable for space-constrained applications. Its fast response time and low clamping voltage ensure effective protection for a wide range of electronic devices. Applications include telecommunications, industrial equipment, and consumer electronics.
