SMBJ28CA

The SMBJ28CA is a TVS diode designed to protect electronic circuits from voltage transients and spikes caused by electrostatic discharge (ESD), lightning, or other transient voltage events. TVS diodes like the SMBJ28CA act as voltage clamps, shunting transient currents away from sensitive components, thus preventing damage to them.

Key Features:

• Transient Voltage Suppression: Provides protection against voltage transients and spikes by clamping voltage levels to a safe threshold.
• Bidirectional Protection: Offers protection against voltage transients in both forward and reverse directions.
• Low Clamping Voltage: Clamps voltage to a low level, diverting transient currents away from protected components.
• Fast Response Time: Reacts quickly to transient events, minimizing the duration of overvoltage conditions.
• High Surge Current Capability: Can withstand short-duration surge currents resulting from transient events.
• Low Leakage Current: Maintains low leakage current during normal operation, ensuring minimal power loss.
• Compact Package: Comes in a small surface-mount package suitable for space-constrained PCB layouts.
• RoHS Compliance: Manufactured with materials and processes compliant with RoHS regulations, ensuring environmental sustainability.

Applications:

• Electronics Protection: Used to protect sensitive electronic components such as integrated circuits (ICs), microcontrollers, and transistors from voltage transients.
• Data and Communication Lines: Integrated into data lines, communication ports (e.g., Ethernet, USB, HDMI), and telecom equipment to safeguard against transient voltages.
• Power Supply Protection: Employed in power supply circuits to protect against voltage surges caused by lightning or switching transients.
• Industrial and Automotive: Utilized in industrial automation systems, automotive electronics, and LED lighting for transient voltage protection.
• Consumer Electronics: Integrated into consumer electronic devices such as smartphones, tablets, and laptops to prevent damage from ESD and transient events.
