MMBZ5V6A-TR

Overview

The MMBZ5V6A-T is a low capacitance unidirectional double ESD protection diode in a common anode configuration, encapsulated in a SOT23 small Surface-Mounted Device plastic package. Designed for protecting up to two signal lines from ElectroStatic Discharge and transient overvoltage, it offers a reverse stand-off voltage of 3 V and a typical clamping voltage of 13 V at 18 A peak pulse current. The device provides ESD protection up to 30 kV per IEC 61000-4-2 standards while maintaining ultra-low leakage current below 200 nA and a diode capacitance of 200 pF typ. at 1 MHz.

Feature Summary

• Unidirectional ESD protection capability for two separate signal lines
• Bidirectional ESD protection functionality for a single line
• Ultra-low leakage current ensuring minimal impact on signal integrity
• Low clamping voltage for effective transient suppression

Applications

• Computers and peripherals
• Audio and video equipment
• Cellular handsets and accessories
• Electronic control units
• Portable electronics

Procurement Notes

Verify the specific ordering suffix matches the required tape and reel packaging format. Confirm that the SOT23 package dimensions align with your PCB footprint requirements. Ensure design compliance with IEC 61000-4-2 and IEC 61000-4-5 standards for your target application environment. Check the latest datasheet revision for any updates to absolute maximum ratings or thermal characteristics before finalizing procurement specifications.

Selection Notes

Select this component when dual-line protection is required within a compact SOT23 footprint. The common anode configuration simplifies circuit layout for ground-referenced signals. Consider the 3 V reverse stand-off voltage limit to ensure compatibility with operating signal levels. Evaluate the 200 pF capacitance against high-speed data line requirements to prevent signal degradation during normal operation.
