CDLL6489/TR

Single Zener Diodes Overview

The CDLL6489/TR is a single Zener diode manufactured by Microchip Technology, designed for voltage regulation and protection applications. It features a nominal Zener voltage of 4.7 V with a tolerance of ±5%. The device operates in the DO-213AB (SMA) surface-mount package and supports a power dissipation of 1.5 W. It functions within an operating temperature range of -65 °C to +175 °C. Key electrical parameters include a Zener impedance of 8 Ohms at a test current of 53 mA, with a maximum reverse leakage current of 4 µA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using a 4.7 V Zener reference.
• Supports high-power dissipation up to 1.5 W for robust circuit protection.
• Operates reliably across an extended industrial temperature range.

Single Zener Diodes Applications

• Voltage regulation in power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage generation in analog signal processing

Single Zener Diodes Procurement Notes

Verify the specific suffix TR indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status as required by project specifications. Ensure the DO-213AB footprint matches the PCB design. Check for any lead-free manufacturing requirements. Validate the manufacturer part number against official Microchip documentation before procurement.

Single Zener Diodes Selection Notes

Select this component for applications requiring a 4.7 V reference with high thermal stability. The 1.5 W power rating allows for handling higher currents compared to standard small-signal diodes. The surface-mount DO-213AB package facilitates automated assembly. Consider the low leakage current for precision analog applications. Verify that the operating temperature range meets environmental constraints.

Single Zener Diodes Part Context

This component belongs to Microchip's line of single Zener diodes. It is part of the CDLL series, which offers surface-mount solutions for voltage regulation. The device complements through-hole variants like the 1N6489 by providing a compact alternative for modern PCB designs.

Single Zener Diodes Replacement Considerations

The 1N6489 is a through-hole equivalent with similar electrical characteristics but different packaging. Surface-mount alternatives in the DO-213AB package should be verified for matching Zener voltage and power ratings. Cross-reference datasheets to ensure compatibility with existing circuit designs.
