KDZVTFTR18B

Single Zener Diodes Overview

The KDZVTFTR18B is a single Zener diode manufactured by ROHM Semiconductor, designed for surface-mount applications in the SOD-123FL package. It features a nominal Zener voltage of 18 V with a tolerance range of 18 V to 20.3 V at a test current of 20 mA. The device supports a maximum power dissipation of 1000 mW and operates within a junction temperature range up to +150 °C. It meets AEC-Q101 automotive qualification standards and offers a maximum reverse leakage current of 10 µA.

Single Zener Diodes Feature Summary

• Automotive-grade reliability certified under AEC-Q101 standards
• High power dissipation capability of 1000 mW in a compact SMD form factor
• Low reverse leakage current for efficient voltage regulation

Single Zener Diodes Applications

• Constant voltage control circuits in automotive electronics
• Voltage reference applications requiring high thermal stability
• Power module integration for surface-mount assembly

Single Zener Diodes Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging configuration before ordering. Confirm that the AEC-Q101 qualification aligns with target automotive project requirements. Ensure the SOD-123FL footprint matches the PCB design constraints. Check for any RoHS compliance documentation updates relevant to the manufacturing batch.

Single Zener Diodes Selection Notes

Select this component when a 1 W Zener diode with automotive certification is required. The SOD-123FL package provides a balance between power handling and board space efficiency. Consider the 20 mA test current requirement for biasing circuit design. Verify compatibility with peak pulse current ratings if used in transient protection scenarios.

Single Zener Diodes Part Context

This part belongs to the KDZVTF series of Zener diodes from ROHM Semiconductor. It serves as a successor or alternative to older non-automotive grades like KDZ18B, offering improved reliability for modern electronic systems. The series is characterized by its robust construction suitable for demanding environmental conditions.

Single Zener Diodes Replacement Considerations

KDZVTF24B: Higher voltage variant (24 V) with identical package and power rating. KDZVTF13B: Lower voltage variant (13 V) with identical package and power rating. KDZV18B: Non-tape version of the same electrical specification.
