CDLL5245B/TR

Single Zener Diodes Overview

The CDLL5245B/TR is a Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 15 V with a tolerance of 5%. The device operates in the DO-213AA-2 surface-mount package and supports a maximum power dissipation of 500 mW. Electrical characteristics include a maximum reverse leakage current of 100 nA and a Zener impedance of 16 Ohms at a test current of 8.5 mA. The component is rated for an operating temperature range from -65°C to +200°C.

Single Zener Diodes Feature Summary

• Provides stable voltage reference through Zener breakdown mechanism
• Utilizes leadless MELF surface mount construction for compact integration
• Supports extended thermal operation up to 200°C

Single Zener Diodes Applications

• Voltage regulation circuits
• Voltage reference sources
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify the specific suffix TR indicates tape and reel packaging configuration when sourcing. Confirm the DO-213AA-2 package dimensions match PCB footprint requirements. Ensure the 5% voltage tolerance aligns with circuit precision needs. Check RoHS compliance status as indicated in official documentation before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component for applications requiring a 15 V reference in a small surface-mount form factor. Consider the 500 mW power rating for thermal management calculations. Evaluate the low leakage current specification for high-impedance circuits. Compare against other Zener voltages in the CDLL52xx series if different reference levels are required.

Single Zener Diodes Part Context

This part belongs to the CDLL52xx series of Zener diodes produced by Microchip Technology. These devices utilize double plug construction and metallurgically bonded leads within a leadless package. The series offers various voltage options ranging from low to high values, all sharing similar physical dimensions and thermal characteristics suitable for automated surface-mount assembly processes.

Single Zener Diodes Replacement Considerations

Direct substitutes include CDLL5245B without the trailing slash TR suffix for bulk packaging variants. Other manufacturers offering equivalent 15 V Zener diodes in DO-213AA or MELF packages may serve as alternatives provided electrical parameters such as impedance and leakage current remain within acceptable limits.
