EMF5XV6T1G

Overview

The EMF5XV6T1G is a quad-channel transient voltage suppression (TVS) diode array manufactured by onsemi. It features unidirectional polarity and operates with a working voltage of 5 V. The device provides a breakdown voltage of 6 V and clamps at 12.5 V under surge conditions. It handles a peak pulse current of 12 A and dissipates up to 200 W of peak pulse power. The component includes an internal ESD protection rating of 9 kV for contact discharge and 16 kV for air gap. It utilizes an SC-88A-5 surface mount package, offers a diode capacitance of 90 pF, and maintains a forward voltage of 1.25 V across an operating temperature range from -55°C to +150°C.

Feature Summary

• Integrates four independent TVS channels within a compact surface-mount footprint for multi-line signal protection.
• Provides robust electrostatic discharge immunity compliant with IEC standards for both contact and air gap discharges.
• Features low clamping voltage characteristics to safeguard sensitive downstream electronics during transient events.

Applications

• Protection of high-speed data interfaces such as USB, HDMI, and DisplayPort lines.
• ESD suppression in mobile communication devices and portable consumer electronics.
• Surge protection for input/output ports in automotive infotainment and control modules.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct polarity and voltage ratings. Confirm RoHS compliance status and lead-free material declarations prior to integration. Cross-reference the SC-88A-5 package dimensions with your PCB footprint library to guarantee mechanical compatibility. Validate thermal performance requirements against the specified peak pulse power dissipation limits for your intended application environment.

Selection Notes

Select this component when designing circuits requiring simultaneous protection for multiple signal lines within a constrained board area. Ensure the chosen TVS array meets the system's required standoff voltage and clamping thresholds without interfering with normal signal integrity. Consider the junction capacitance value relative to the data rate of the protected interface to minimize signal attenuation. Verify that the peak pulse current capability exceeds the maximum expected surge currents in the target deployment scenario.

Part Context

This part belongs to the SMF05TxG series of quad-channel TVS diodes designed for compact ESD protection solutions. The series is engineered to replace discrete diode arrangements, thereby reducing component count and assembly complexity. It serves as a specialized solution for protecting high-density interconnects in modern electronic devices where space is limited and multiple lines require simultaneous surge defense.

Replacement Considerations

Direct replacements include other quad-channel TVS arrays from onsemi with matching electrical parameters and pin configurations. Verify compatibility with alternative manufacturers offering similar SC-88A-5 packaged solutions. Ensure substitute parts maintain identical breakdown voltage, clamping voltage, and capacitance values to preserve circuit performance.
