SVC272-TL-EX

Overview

The SVC272-TL-EX is a transient voltage suppressor (TVS) diode manufactured by onsemi. It is designed to protect sensitive electronic circuits from voltage spikes and electrostatic discharge (ESD). The component features a bidirectional configuration, allowing it to clamp both positive and negative transients effectively. It utilizes a DO-214AB (SMB) surface-mount package for compact integration into printed circuit boards. The device offers high peak pulse power dissipation capabilities to absorb energy during transient events without sustaining damage.

Feature Summary

• Bidirectional clamping capability for AC signal lines
• High peak pulse power absorption
• Low leakage current in standby mode
• Fast response time to transient events

Applications

• Protection of data bus lines in communication interfaces
• ESD protection for I/O ports on consumer electronics
• Surge suppression in automotive sensor circuits
• Transient voltage limiting in industrial control systems

Procurement Notes

Verify the exact electrical parameters such as breakdown voltage and peak pulse current against the official onsemi datasheet before procurement. Confirm that the DO-214AB package dimensions match the PCB footprint requirements. Ensure the bidirectional variant is selected if the application involves AC signals or bipolar DC lines. Check for RoHS compliance status if required by specific regulatory standards.

Selection Notes

Select this component when bidirectional transient protection is required for low-capacitance signal lines. Evaluate the maximum operating voltage of the protected line to ensure the standoff voltage is appropriate. Consider the peak pulse power rating relative to the expected surge energy levels in the target environment. Compare capacitance values if high-speed data integrity is critical to avoid signal degradation.

Part Context

The SVC series represents onsemi's lineup of transient voltage suppressors designed for general-purpose protection applications. These devices are engineered to provide robust defense against ESD and lightning-induced surges. The SMB package offers a balance between power handling capacity and board space efficiency, making it suitable for dense electronic assemblies.

Replacement Considerations

Check for direct equivalents from other manufacturers offering similar bidirectional TVS characteristics in the DO-214AB package. Verify that any substitute part matches the peak pulse power dissipation and breakdown voltage tolerances. Ensure the replacement maintains comparable capacitance levels to preserve signal integrity in high-speed applications.
