Overview
The UMZ5.1KFHTL is a Zener diode manufactured by ROHM Semiconductor, designed for automotive applications in compliance with the AEC-Q101 standard. It features a dual-line configuration housed in an SOT-343 (UMD2) package with dimensions of 2.1x2.0 mm and a thickness of 1.0 mm. The device has a typical Zener voltage of 5.1 V, with a minimum of 4.98 V and a maximum of 5.2 V, tested at a current of 5 mA. It supports a power dissipation of 200 mW, operates within a junction temperature range up to 150°C, and functions within a storage temperature range of -55°C to 150°C.
Feature Summary
- Dual-line configuration for space-efficient circuit design
- Automotive-grade reliability compliant with AEC-Q101 standards
- Compact surface-mount packaging suitable for high-density boards
Applications
- Voltage reference circuits in automotive electronics
- Transient voltage suppression in vehicle control modules
- Over-voltage protection for sensitive IC inputs
Procurement Notes
Verify the specific ordering suffix TL against the official datasheet to ensure correct taping quantity and packing type. Confirm supply status as Not Recommended for New Designs (NRND) before finalizing procurement plans. Check RoHS compliance documentation for environmental regulatory adherence. Ensure compatibility with existing inventory strategies due to potential end-of-life constraints.
Selection Notes
Select this component when a dual Zener configuration is required in a small SOT-343 package for automotive systems. Verify that the 5.1 V nominal voltage and 200 mW power rating meet the circuit's thermal and electrical requirements. Consider the AEC-Q101 qualification if the application demands automotive-grade reliability standards.
Part Context
This part belongs to ROHM's UMZ series of Zener diodes, which are specifically engineered for automotive use. The series emphasizes compactness and high reliability, utilizing plastic mold packages to withstand harsh automotive environments while maintaining precise voltage regulation characteristics.
Replacement Considerations
The EDZVFH22B is listed as a similar specification alternative. Verify pinout compatibility and package dimensions before substitution. Confirm that the replacement meets all AEC-Q101 requirements and matches the electrical parameters of the original design.
