CDLL4736

Single Zener Diodes Overview

The CDLL4736A 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 operates within a temperature range of -65°C to +175°C and exhibits a maximum Zener impedance of 3.5 Ohms. Reverse leakage current is specified at 3 µA when tested at 4 V, while the forward voltage drop is 1.2 V at a forward current of 200 mA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation with a nominal breakdown voltage of 6.8 V
• Capable of operation across an extended industrial temperature range up to 175°C
• Utilizes a compact glass-encapsulated MELF surface-mount form factor

Single Zener Diodes Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in sensitive electronic systems
• Clamping applications for transient voltage suppression

Single Zener Diodes Procurement Notes

Verify compliance requirements prior to procurement as this component does not meet RoHS standards. Confirm that the specific suffix 'A' denotes the required tolerance level for your design. Ensure the DO-213AB package dimensions align with your printed circuit board layout constraints before finalizing orders.

Single Zener Diodes Selection Notes

Select this component when a 6.8 V reference is needed in a small surface-mount footprint. The wide operating temperature range supports harsh environments. Compare the 3.5 Ohm impedance against load regulation requirements. Verify that the non-RoHS status meets regulatory needs for the target market.

Single Zener Diodes Part Context

This part belongs to the CDLL4736 family of Zener diodes produced by Microchip Technology. It shares the same electrical characteristics as the through-hole 1N4736A but utilizes a different surface-mount package. The device is categorized under discrete semiconductor diodes and rectifiers.

Single Zener Diodes Replacement Considerations

The CDLL4736A/TR serves as a parameter-equivalent reel-pack alternative from the same manufacturer. Cross-brand replacements must match the 6.8 V Zener voltage, ±5% tolerance, and DO-213AB package dimensions to ensure functional compatibility.
