1N4698UR-1E3/TR

Overview

The Microchip Technology 1N4698UR-1E3/TR is a surface mount Zener voltage regulator in the DO-213AA (MELF) package. It provides an 11 V nominal Zener voltage with a standard tolerance of ±5%. The device operates at a test current of 50 µA and dissipates up to 0.5 W. It features a hermetically sealed glass construction with metallurgically bonded metal slugs for high reliability.

Feature Summary

• Hermetically sealed glass MELF package with internal metallurgical bonding
• Surface mount equivalent of JEDEC registered through-hole series
• RoHS compliant commercial grade availability

Applications

• Voltage regulation over broad operating current and temperature ranges
• ESD protection circuits requiring minimal capacitance
• Radiation-hardened applications utilizing inherent radiation hardness properties

Procurement Notes

Verify RoHS compliance status, as it applies only to commercial grade devices. Confirm the specific suffix indicates tape and reel packaging per EIA-481-1-B standards. Ensure the ordering part number matches the required voltage tolerance level, as tighter tolerances require distinct suffixes.

Selection Notes

Select this component for applications requiring a surface mount alternative to traditional axial leads. The DO-213AA package offers a compact footprint while maintaining high reliability through metallurgical bonding. Consider the low test current requirement of 50 µA when designing bias networks.

Part Context

This part belongs to the 1N4678UR-1 thru 1N4717UR-1 series of 0.5 watt Zener diodes. The series covers a voltage selection from 1.8 to 43 volts. It serves as the surface mount counterpart to the JEDEC registered 1N4678 through 1N4717 axial leaded series.

Replacement Considerations

Direct replacement options include other 1N4698 variants within the same series or the through-hole 1N4698 in DO-35 packages if board space permits.
