The SMEJ22AG/TR13 is a transient voltage suppressor (TVS) diode manufactured by Yageo. It's designed to protect sensitive electronic components from voltage transients caused by events like lightning strikes, inductive load switching, and electrostatic discharge (ESD). By quickly clamping overvoltage conditions, it diverts excess current away from vulnerable circuits.

Applications

• Power Supplies: Provides protection for power supplies against voltage surges and transients.
• Industrial Equipment: Used in industrial control systems and automation equipment to protect against transient voltages.
• Telecommunications Equipment: Safeguards telecommunication lines and equipment from lightning-induced surges.
• Automotive Electronics: Employed in automotive electronic control units (ECUs) to protect against voltage transients and ESD.
• Consumer Electronics: Offers surge protection for various consumer electronic devices.

Features

• Unidirectional Protection: Provides protection against positive voltage transients.
• Surface Mount Package: Designed for automated assembly and efficient use of board space.
• High Surge Capability: Capable of withstanding high surge currents without degradation.
• Low Clamping Voltage: Limits the voltage across the protected circuit during a surge event.
• RoHS Compliant: Complies with the Restriction of Hazardous Substances (RoHS) directive.

Benefits

• Enhanced Circuit Protection: Provides robust protection against voltage transients and ESD.
• Improved System Reliability: Protects sensitive electronic components from damage, increasing overall system reliability.
• Reduced Downtime: Prevents damage from surge events, minimizing downtime and maintenance costs.
• Prolonged Product Lifespan: Extends the lifespan of electronic equipment by protecting it from voltage stresses.
• Simplified Design: Facilitates easy integration into circuit designs with a compact footprint.

Additional Details

The SMEJ22AG/TR13 has a standoff voltage of 22V, meaning that it remains non-conductive until the voltage exceeds this level. During a surge event, it clamps the voltage to a specified clamping voltage. The component is characterized by its peak pulse power dissipation rating, which signifies its ability to handle high-energy surges. It has a surge current rating. The typical operating temperature range is -55°C to +150°C. Refer to the manufacturer's datasheet for detailed electrical characteristics, surge handling capabilities, and other performance parameters.
