The SMAJ140CA is a surface-mount Transient Voltage Suppressor (TVS) diode manufactured by JSCJ (JCET). This diode is specifically designed to protect sensitive electronic equipment from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). It features a power dissipation of 400W and a reverse standoff voltage of 140V. The SMAJ140CA is housed in a compact SMA package, making it suitable for high-density circuit board applications. Its fast response time and low clamping voltage ensure effective protection against overvoltage events. As an authorized distributor of JSCJ (JCET) components, Supreme Components International guarantees the authenticity and quality of the SMAJ140CA. This TVS diode is commonly used in telecommunications, industrial control, and consumer electronics applications to enhance system reliability and prevent damage from voltage surges.
