The SMDJ22A is a high-performance Transient Voltage Suppressor (TVS) diode manufactured by JSCJ (JCET). Supreme Components International is an authorised distributor of this component. This unidirectional TVS diode is designed to protect sensitive electronic equipment from voltage transients induced by lightning, ESD, and other transient voltage events. With a peak pulse power dissipation of 600W, the SMDJ22A effectively clamps transient voltages to safe levels, preventing damage to downstream circuitry. It features a 22V standoff voltage and is available in a compact DO-214AB (SMC) surface-mount package, making it suitable for automated assembly. The SMDJ22A is ideal for applications such as automotive electronics, industrial control systems, and telecommunications equipment where reliable overvoltage protection is critical. Its robust construction and excellent surge handling capability ensure long-term reliability and performance.
