CDLL5281D/TR

Single Zener Diodes Overview

The CDLL5281D/TR is a single Zener diode manufactured by Microchip Technology, designed for surface-mount applications in the DO-213AA package. It features a nominal Zener voltage of 200 V with a tolerance of ±20%. The device operates within a temperature range of -65°C to +175°C and exhibits a maximum reverse leakage current of 100 nA. Packaged in tape and reel format, it serves as a voltage regulator component suitable for high-temperature environments.

Single Zener Diodes Feature Summary

• High-temperature operation capability up to 175°C
• Surface-mount construction in compact DO-213AA package
• Single Zener configuration for voltage regulation

Single Zener Diodes Applications

• Voltage regulation circuits requiring high-temperature stability
• Protection against overvoltage transients in harsh environments
• Reference voltage generation in industrial electronics

Single Zener Diodes Procurement Notes

Verify the specific suffix D/TR indicates tape and reel packaging when sourcing. Confirm the DO-213AA footprint compatibility with PCB design. Ensure the ±20% voltage tolerance aligns with circuit requirements. Check for RoHS compliance status if restricted substances are prohibited in the application.

Single Zener Diodes Selection Notes

Select this component when a 200 V Zener reference is needed in a small surface-mount form factor. The wide operating temperature range makes it suitable for automotive or industrial sectors. Compare leakage current specifications against other high-voltage Zener options to ensure minimal power loss in standby modes.

Single Zener Diodes Part Context

This part belongs to the CDLL5281 series of Zener diodes from Microchip Technology. It shares the same package style as other variants in the family but differs in breakdown voltage. The TR suffix denotes the specific reel packaging method used for automated assembly processes.

Single Zener Diodes Replacement Considerations

CDLL5281D is the non-reel equivalent. CDLL5281C/TR may serve as a substitute if lower voltage ratings are acceptable.
