DL5252B-TP

Single Zener Diodes Overview

The DL5252B-TP is a 500 mW silicon Zener diode manufactured by Micro Commercial Components (MCC). It features a MiniMelf surface-mount package and provides a nominal Zener voltage of 24 V with a ±5% tolerance. The device operates within an ambient temperature range of -65°C to +175°C and includes high-temperature soldering capability at 260°C for 10 seconds. Key electrical parameters include a maximum reverse leakage current of 0.1 µA, a test current of 5.2 mA, and a maximum Zener impedance of 33 Ohms.

Single Zener Diodes Feature Summary

• Hermetically sealed glass MiniMelf package designed for surface mount applications
• High thermal stability supporting operation up to +175°C junction temperature
• Low reverse leakage current characteristics suitable for precision regulation
• Robust construction allowing high-temperature soldering without damage

Single Zener Diodes Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection in sensitive electronic systems
• Precision power supply regulation modules

Single Zener Diodes Procurement Notes

Verify the specific 'B' suffix indicates the required ±5% voltage tolerance during procurement. Confirm that the MiniMelf package dimensions match the target PCB footprint. Ensure sourcing channels are authorized distributors to guarantee component authenticity and traceability. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Single Zener Diodes Selection Notes

Select this component when a 24 V regulation point is needed in a compact surface-mount design. The MiniMelf form factor offers lower profile compared to axial leads while maintaining hermetic sealing. Consider the 500 mW power dissipation limit and derating requirements above 50°C. Evaluate the 33 Ohm impedance against circuit noise sensitivity requirements.

Single Zener Diodes Part Context

This part belongs to the DL5221 through DL5267 series from MCC, covering a wide voltage range from 2.4 V to 75 V. The 'B' suffix specifically denotes a tighter ±5% manufacturing tolerance on the Zener voltage compared to standard variants. The series utilizes metallurgically bonded glass packages for high reliability in harsh environments.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering MiniMelf packaged Zener diodes rated at 24 V and 500 mW. Verify that alternative parts meet the same -65°C to +175°C operating temperature range and possess comparable leakage current specifications.
