UFZVFHTE-1712B

Single Zener Diodes Overview

The UFZVFHTE-1712B is a single Zener diode manufactured by ROHM Semiconductor, designed for surface-mount applications. It features a nominal Zener voltage of 12 V with a tolerance range of 11.51 V to 12.16 V at a test current of 10 mA. The component operates within the SOD-323FL (UMD2) package, which measures 1.8 mm in length, 1.35 mm in width, and 0.9 mm in height. It supports a maximum power dissipation of 500 mW and maintains a low Zener impedance of 12 Ohms. The device exhibits a maximum reverse leakage current of 200 nA and is qualified under the AEC-Q101 standard for automotive reliability.

Single Zener Diodes Feature Summary

• Automotive-grade qualification compliant with AEC-Q101 standards
• High power dissipation capability of 500 mW in a compact footprint
• Low Zener impedance of 12 Ohms for stable voltage regulation
• Surface-mount design in the small SOD-323FL package

Single Zener Diodes Applications

• Voltage reference circuits in automotive electronics
• Over-voltage protection stages in vehicle control modules
• Clamping applications in high-reliability semiconductor systems

Single Zener Diodes Procurement Notes

Verify the specific suffix '1712B' against official ROHM documentation to confirm the exact voltage tolerance and test current parameters. Ensure that the SOD-323FL package dimensions align with the target PCB layout constraints. Confirm AEC-Q101 compliance requirements if the application involves automotive environments. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Single Zener Diodes Selection Notes

Select this component when a 12 V reference requires higher power handling than standard 200 mW diodes. The SOD-323FL package offers a smaller profile compared to traditional SOD-323 variants. Consider the 12 Ohm impedance for noise-sensitive designs. Verify thermal management capabilities given the 500 mW rating in confined spaces.

Single Zener Diodes Part Context

This component belongs to the UFZVFHTE series of Zener diodes from ROHM Semiconductor. The series is characterized by its automotive qualification and enhanced power dissipation relative to lower-power counterparts. It utilizes the UMD2/SOD-323FL package format, which is widely adopted in space-constrained modern electronic assemblies requiring robust voltage regulation.

Single Zener Diodes Replacement Considerations

Direct substitutes include other ROHM parts within the UFZVFHTE series sharing the same voltage and package, such as UFZVFHTE-176.2B or UFZVFHTE-1722B, provided the voltage ratings match the circuit requirements.
