MAD1106E3/TU

Diode Arrays Overview

The MAD1106E3/TU is an eight-element, unidirectional silicon Transient Voltage Suppressor (TVS) diode array manufactured by Microsemi Corporation. It is housed in a 14-pin Small Outline Integrated Circuit (SOIC) package with a lead-free finish indicated by the 'e3' suffix and tape-and-reel packaging denoted by 'TU'. The device provides electrostatic discharge (ESD) protection for multiple input/output lines within a compact surface-mount footprint.

Diode Arrays Feature Summary

• Provides integrated ESD protection for up to eight I/O ports using a single component
• Features low capacitance characteristics suitable for high-speed data line applications
• Utilizes a planar process for improved reliability and reduced board space requirements

Diode Arrays Applications

• Protection of high-speed data interfaces such as USB, HDMI, or DVI ports
• ESD suppression in computer peripheral equipment
• Surge protection for decoding or encoding logic circuits

Diode Arrays Procurement Notes

Verify the specific manufacturer source, as this part number has been associated with both Microsemi and Microchip Technology due to corporate acquisition history. Confirm that the 'TU' suffix correctly indicates tape-and-reel packaging and that the 'e3' designation confirms RoHS compliance with matte tin termination. Ensure the datasheet matches the required voltage ratings for your specific circuit design before procurement.

Diode Arrays Selection Notes

Select this component when designing systems requiring multi-line ESD protection in a small form factor. The unidirectional configuration is appropriate for DC-coupled signal lines where polarity is fixed. Consider the SO-14 package constraints regarding thermal dissipation and PCB layout clearance. Verify that the breakdown voltage aligns with the operating voltage of the protected signals to prevent false triggering during normal operation.

Diode Arrays Part Context

This device belongs to the MAD11xx series of steering diode arrays designed for protecting digital I/O lines. These arrays consolidate multiple discrete junctions into a single package to simplify assembly and improve reliability compared to using individual components. The technology is commonly used in consumer electronics and industrial control systems where space efficiency and robust transient protection are critical design parameters.
