The SMBJ300A is a high-performance Transient Voltage Suppressor (TVS) diode manufactured by JSCJ (JCET). This unidirectional diode is specifically designed to protect sensitive electronic equipment from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). With a standoff voltage of 300V and a peak pulse power dissipation of 600W, the SMBJ300A provides robust overvoltage protection. Its fast response time and low clamping voltage ensure effective protection for downstream components. The SMB package allows for easy surface mounting. Supreme Components International is an authorized distributor of JSCJ components, guaranteeing genuine products and reliable performance. This TVS diode is suitable for a wide range of applications, including telecommunications, industrial control, and consumer electronics.
