The CJSMAJ45A is a surface-mount Transient Voltage Suppressor (TVS) diode from JSCJ (JCET), designed to protect sensitive electronic equipment from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching. With a peak pulse power dissipation of 400W, this diode effectively clamps transient voltages to safe levels, preventing damage to downstream components. Its reverse standoff voltage is 45V. The CJSMAJ45A is housed in a compact SMA package, making it suitable for high-density circuit board layouts. Supreme Components International is an authorised distributor of JSCJ (JCET) components, ensuring you receive genuine and reliable products. This TVS diode is ideal for applications in telecommunications, industrial control, and consumer electronics.
