CDLL754A/TR

Single Zener Diodes Overview

The CDLL754A/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 6.8 V with a tolerance of ±5%. The device supports a maximum power dissipation of 500 mW and operates within an extended temperature range from -65°C to +175°C. Key electrical characteristics include a maximum reverse leakage current of 2 µA at 4 V, a Zener impedance of 5 Ohms, and a forward voltage of 1.1 V at 200 mA. It is supplied in reel packaging.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation with a nominal 6.8 V Zener breakdown.
• Engineered for high-temperature reliability with operation up to +175°C.
• Utilizes a compact DO-213AB MELF surface-mount package for automated assembly.

Single Zener Diodes Applications

• Voltage reference circuits requiring precise potential levels.
• Overvoltage protection stages in sensitive electronic systems.
• Clamping applications in signal processing paths.

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against official Microchip documentation to ensure compatibility with required testing currents and impedance specifications. Confirm that the DO-213AB package dimensions align with the target PCB footprint. Cross-reference the manufacturing date code and RoHS status with current product announcements to guarantee compliance with project environmental standards and supply chain requirements.

Single Zener Diodes Selection Notes

Select this component when a 6.8 V regulation point is required in a space-constrained surface-mount design. The low Zener impedance of 5 Ohms suggests suitability for applications demanding tighter voltage stability under varying load conditions. Ensure the thermal management strategy accommodates the 500 mW power dissipation limit within the specified operating temperature range.

Single Zener Diodes Part Context

This part belongs to the CDLL754 series of axial-equivalent Zener diodes adapted for surface-mount technology. The 'TR' suffix indicates tape-and-reel packaging, facilitating high-volume automated placement. It serves as a modern replacement for through-hole variants in compact consumer and industrial electronics where board real estate is limited.
