CDLL5234A/TR

Single Zener Diodes Overview

The CDLL5234A/TR is a single Zener diode manufactured by Microchip Technology, designed for surface-mount applications in the DO-213AB MELF package. It features a nominal Zener voltage of 6.2 V with a tolerance of ±10%. The device operates within a temperature range of -65°C to +175°C and exhibits a maximum Zener impedance of 7 Ohms. Reverse leakage current is specified at 5 µA when tested at 4 V, while the forward voltage drop is 1.1 V at a forward current of 200 mA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using a single Zener junction structure.
• Capable of operation across an extended industrial temperature range up to 175°C.
• Utilizes a compact MELF surface-mount package for automated assembly.

Single Zener Diodes Applications

• Voltage reference circuits requiring precise potential levels.
• Overvoltage protection stages in electronic systems.
• Clamping applications for transient suppression.

Single Zener Diodes Procurement Notes

Verify that the specific suffix '/TR' indicates tape-and-reel packaging rather than bulk supply. Confirm RoHS compliance status as documentation may indicate non-compliance depending on the manufacturing batch. Ensure the ordering quantity aligns with the manufacturer's standard reel size requirements to avoid partial reel handling issues.

Single Zener Diodes Selection Notes

Select this component when a 6.2 V regulation point is required in a small form factor. The low Zener impedance supports effective noise filtering. Verify that the thermal management strategy accommodates the power dissipation limits inherent to the MELF package geometry during continuous operation.

Single Zener Diodes Part Context

This part belongs to the CDLL5234 series of axial-equivalent surface-mount Zener diodes. It shares functional characteristics with through-hole variants but offers improved mounting density. The MELF construction provides hermetic sealing properties suitable for harsh environments.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' DO-213AB Zener diodes with identical 6.2 V ratings and ±10% tolerance. Verify pinout compatibility and thermal resistance values before substitution.
