SMC0517

Overview

The SMC0517 is a specialized integrated circuit manufactured by onsemi, categorized under Specialized ICs. It is designed for transient voltage suppression applications within the SMF CT series family. The component utilizes surface-mount technology (SMD/SMT) and is housed in an SC-88-6 (SOT-363-6) package. It features five channels of protection with a unidirectional configuration. Key electrical specifications include a working voltage of 5 V, a breakdown voltage of 6.2 V, and a clamping voltage of 12.5 V. The device supports a peak pulse current of 8 A and handles a peak pulse power dissipation of 100 W. It exhibits a diode capacitance of 80 pF and provides electrostatic discharge protection up to 15 kV for both contact and air gap discharges. The operational temperature range spans from -40°C to +125°C.

Feature Summary

• Provides multi-line transient voltage suppression for sensitive electronic circuits
• Offers robust electrostatic discharge protection rated at 15 kV
• Features low capacitance design to maintain signal integrity
• Utilizes compact surface-mount packaging for space-constrained layouts

Applications

• Protection of high-speed data lines in consumer electronics
• ESD suppression for portable device interfaces
• Transient voltage protection in automotive infotainment systems
• Signal line protection in industrial control modules

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with onsemi or authorized distributors before integration. Confirm that the SC-88-6 footprint matches your PCB layout requirements. Ensure that the thermal management strategy accounts for the 100 W peak pulse rating during transient events. Cross-reference the pinout diagram with your schematic to prevent misalignment during assembly.

Selection Notes

Select this component when designing circuits requiring multi-channel ESD protection for low-voltage signals. The unidirectional configuration is suitable for DC-coupled lines where reverse polarity is not expected. Consider the 80 pF capacitance value to ensure it does not degrade signal bandwidth in high-frequency applications. Verify that the operating temperature range meets the environmental conditions of the final product deployment.
