Taiwan Semiconductor SMBJ24CA

Taiwan Semiconductor SMBJ24CA Environmental and export classification status description

The SMBJ24CA is a transient voltage suppressor (TVS) diode designed to provide circuit protection by clamping voltage spikes. It is part of the SMBJ series, featuring a bidirectional design suitable for various applications that require surge protection. The device is capable of handling high peak power and can limit voltage spikes generated by electrical surges. Functions 1. Surge Protection: The primary function of the SMBJ24CA is to protect sensitive electronic circuits from voltage transients caused by ESD (electrostatic discharge), lightning, and other transient events. 2. Clamping: It provides effective clamping at a specified breakdown voltage, preventing excess voltage from reaching the load. 3. Bidirectional Operation: This component is especially useful for AC and DC applications where voltage can swing in both directions. Applications - Telecommunications: Protecting equipment from lightning strikes and voltage transients. - Consumer Electronics: Safeguarding devices such as TVs, radios, and game consoles. - Automotive Design: Ensuring the integrity of electronic systems in vehicles from voltage spikes. - Industrial Equipment: Protecting machinery and control systems from electrical noise and surges. - Computers and Peripherals: Shielding data lines and power input from dangerous voltage levels. Alternative Parts - SMBJ20CA: Similar specifications but with a lower breakdown voltage. - SMBJ29CA: Higher rated voltage which could be a suitable alternative in some applications. - ESD5Z3.3/ESD5Z5.0: Specialized for ESD protection with different breakdown voltages. - ESD7Z5.0: Another alternative for applications needing reliable ESD protection. Embedded Modules While the SMBJ24CA itself is not typically categorized under embedded modules, it can be found within boards or circuits that utilize TVS diodes for circuit protection. Some PCB designs integrate this component alongside microcontrollers, sensors, and other ICs to guard against transient voltages. Related Q&A 1.
