UMZ8.2NFHT106

Overview

The UMZ8.2NFHT106 is a dual common-anode Zener diode array manufactured by ROHM Semiconductor, designed for terminal protection applications in automotive environments. It operates within the SOT-323 (UMD3) surface-mount package, featuring a nominal Zener voltage of 8.2 V with a tight tolerance of ±2%. The device supports a maximum power dissipation of 200 mW and maintains a low reverse leakage current of 100 nA at 5.6 V. Certified to AEC-Q101 standards, it ensures high reliability with a junction temperature rating of up to 150°C and complies with RoHS directives.

Feature Summary

• Dual common-anode configuration optimized for efficient circuit board space utilization in compact electronic assemblies.
• Automotive-grade construction certified under AEC-Q101 standards to ensure long-term stability and reliability in demanding vehicle environments.
• Low capacitance design facilitates effective electrostatic discharge (ESD) protection while preserving signal integrity in sensitive data lines.

Applications

• I/O port protection for automotive infotainment systems and control units
• Signal line safeguarding against transient voltage spikes in connected peripherals
• Electrostatic discharge (ESD) mitigation on communication interfaces

Procurement Notes

Verify the specific ordering suffix HT106 to confirm tape-and-reel packaging containing 3000 units per reel. Ensure the procurement documentation explicitly references the AEC-Q101 qualification status required for automotive integration. Cross-reference the manufacturer part number against official ROHM databases to validate authenticity and traceability before finalizing acquisition orders.

Selection Notes

Select this component when a dual-channel solution is required for bidirectional or unidirectional ESD protection on paired signal lines. The 8.2 V breakdown voltage suits 5 V logic systems, providing adequate clamping without interfering with normal operation. Verify that the 200 mW power rating aligns with the expected energy absorption requirements of the target application environment.

Part Context

This device belongs to the UMZ series of low-capacitance Zener arrays specifically engineered for protecting I/O ports in automotive electronics. It shares the UMD3 package footprint with other variants in the family, such as the UMZ18NFHT106, allowing for standardized layout designs across different voltage protection levels within the same product line.

Replacement Considerations

Direct pin-compatible substitutes within the same series include the UMZ5.6NFHT106 and UMZ18NFHT106. These alternatives offer identical package dimensions and electrical configurations but differ in their nominal Zener voltage ratings. Evaluate the specific clamping voltage requirements of the circuit before substituting to ensure proper protection thresholds are maintained.
