The SMAJ58A 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 equipment from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). It features a standoff voltage of 58V and a peak pulse power dissipation of 400W. The SMAJ58A is available in a compact SMA (DO-214AC) package, making it suitable for high-density circuit board applications. Its fast response time and low clamping voltage ensure effective protection against overvoltage events. Common applications include power supplies, telecommunications equipment, and industrial control systems.
