The SMAJ220A is a Transient Voltage Suppressor (TVS) diode manufactured by JSCJ (JCET). This unidirectional TVS diode is designed to protect sensitive electronic components from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching. With a standoff voltage of 220V and a peak pulse power dissipation of 400W, the SMAJ220A effectively clamps transient voltages to safe levels, preventing damage to downstream circuitry. It is packaged in a surface-mount SMA (DO-214AC) package, making it suitable for automated assembly. Supreme Components International is an authorised distributor of JSCJ (JCET) components, ensuring you receive genuine and high-quality products. This TVS diode is ideal for use in power supplies, communication equipment, industrial controls, and other applications requiring robust overvoltage protection. Its fast response time and low clamping voltage make it an excellent choice for safeguarding sensitive electronics.
