1N4618URE3

Single Zener Diodes Overview

The Microchip Technology 1N4618URE3 is a 0.5 W Zener voltage regulator in the surface mount DO-213AA glass package. It provides a nominal Zener voltage of 2.7 V with a standard 5% tolerance. The device features an internal metallurgical bond and operates within a junction temperature range of -65 °C to +175 °C. It is RoHS compliant and available in commercial grades.

Single Zener Diodes Feature Summary

• Internal metallurgical bond construction for enhanced reliability
• Hermetically sealed glass DO-213AA surface mount package
• Low noise density characteristics suitable for precision applications

Single Zener Diodes Applications

• Voltage regulation over broad current and temperature ranges
• High reliability electronic circuits requiring hermetic sealing
• Radiation-hardened system designs

Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required qualification level, as military variants carry prefixes such as JAN or JANTXV. Confirm RoHS compliance status, as it applies only to commercial grade versions. Ensure the package type aligns with the intended surface mount footprint requirements.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed surface mount Zener diode is required. The 2.7 V nominal voltage and 5% tolerance suit general regulation tasks. Consider the low noise density for sensitive signal paths. Verify thermal derating curves against the expected ambient operating conditions.

Single Zener Diodes Part Context

This part belongs to the 1N4614UR-1 through 1N4627UR-1 series of 0.5 W metallurgically bonded glass surface mount Zener diodes. The series offers voltages from 1.8 to 100 V. It serves as the surface mount equivalent to the JEDEC registered 1N4099 through 1N4135 and 1N4614 through 1N4627 axial leaded series.

Single Zener Diodes Replacement Considerations

The CDLL4618-1 prefix denotes the same device family under the Microsemi designation. Commercial equivalents may use the CDLL prefix instead of MLL. Verify package compatibility before substituting.
