KDZLVTR120

Single Zener Diodes Overview

The KDZLVTR120 is a single Zener diode manufactured by ROHM Semiconductor, designed for surface-mount applications. It features a nominal Zener voltage of 120 V with a tolerance of ±5%. The device is rated for a power dissipation of 1 W and operates within a junction temperature range up to +150°C. It utilizes the PMDU (SOD-123FL) package configuration. Key electrical parameters include a maximum reverse leakage current of 5 µA at 91 V and a Zener impedance of 1.25 kΩ measured at a test current of 2 mA. The component holds AEC-Q101 qualification for automotive reliability standards.

Single Zener Diodes Feature Summary

Single Zener Diodes Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing. Confirm AEC-Q101 compliance requirements match your target application's quality standards. Ensure the PMDU package footprint aligns with your PCB layout constraints. Cross-reference the manufacturer part number directly with official ROHM documentation to avoid counterfeit components.

Single Zener Diodes Selection Notes

Select this component when a stable 120 V reference or clamp is required in high-temperature environments. The 1 W power rating supports moderate surge currents compared to lower-power variants. Consider the SOD-123FL package size if board real estate is limited. Verify that the 5 µA leakage current meets the sensitivity requirements of the connected circuitry.

Single Zener Diodes Part Context

This part belongs to the KDZLV series of single Zener diodes from ROHM Semiconductor. The series is characterized by its automotive qualification and robust construction for harsh environments. The KDZLVTR120 specifically targets the 120 V voltage segment within this lineup, offering a balance of voltage precision and power handling suitable for industrial and automotive electronics.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 120 V Zener voltage, 1 W power rating, and SOD-123FL package. Verify equivalent AEC-Q101 certification if automotive use is intended. Check for identical leakage current and impedance specifications to ensure circuit compatibility without redesign.
