The SMBJ26AT is a Transient Voltage Suppressor (TVS) diode manufactured by Vishay. This TVS diode is designed to protect sensitive electronic components from voltage transients induced by lightning, electrostatic discharge (ESD), and other transient voltage events.

Applications:

• Data Lines Protection: Used to protect data lines in communication equipment and computer interfaces.
• Power Supply Protection: Employed to protect power supplies from voltage surges and spikes.
• Industrial Equipment: Integrated into industrial control systems to protect sensitive electronics.
• Consumer Electronics: Used in consumer devices such as televisions, set-top boxes, and gaming consoles.
• Automotive Electronics: Employed in automotive systems to protect electronic components from transient voltages.

Features:

• Unidirectional Configuration: Provides unidirectional voltage suppression.
• Fast Response Time: Quickly clamps transient voltages to protect sensitive components.
• Low Clamping Voltage: Limits the voltage across the protected component during transient events.
• High Surge Capability: Designed to withstand high surge currents.
• SMB Package: Available in a compact SMB (Surface Mountable) package for easy board mounting.

Benefits:

• Enhanced Protection: Protects electronic components from damage due to transient voltage events.
• Improved Reliability: Increases the reliability and lifespan of electronic equipment.
• Simplified Design: Easy to integrate into existing circuits with minimal additional components.
• Compact Size: Small SMB package saves valuable board space.

Additional Details:

The SMBJ26AT has a standoff voltage of 26V, meaning it starts conducting and clamping at voltages above this level. It has a peak pulse power dissipation capability of 600W. It is designed to provide robust protection against various transient voltage threats and maintain long-term reliability in a wide range of operating conditions. The SMB package facilitates automated assembly and ensures good thermal performance.
