1N4698CUR-1E3/TR

Overview

The Microchip Technology 1N4698CUR-1E3/TR is a surface mount Zener voltage regulator in the DO-213AA (MELF) package. It provides a nominal Zener voltage of 11 V with a tight tolerance of ±2%. The device operates at a test current of 50 µA and supports a maximum DC power dissipation of 0.5 W. It features a hermetically sealed glass construction with internal metallurgical bonding for high reliability.

Feature Summary

• Hermetically sealed glass MELF package with internal metallurgical bond
• Tight voltage tolerance of ±2% available
• RoHS compliant commercial grade option
• Non-sensitive to electrostatic discharge

Applications

• Voltage regulation over broad operating current and temperature ranges
• Radiation-hardened applications
• Low capacitance circuit requirements

Procurement Notes

Verify that the specific ordering suffix matches the required RoHS compliance status, as this attribute applies only to commercial grade devices. Confirm the tolerance designation corresponds to the desired ±2% specification. Ensure the tape and reel packaging aligns with automated assembly needs. Cross-reference the manufacturer's latest datasheet for any updates on screening options or availability constraints.

Selection Notes

Select this component when a surface mount equivalent to the JEDEC registered 1N4678 series is required. The 1N4698 variant specifically targets an 11 V regulation point. Consider the low capacitance characteristics if signal integrity is critical. Verify thermal resistance parameters against the PCB footprint design to ensure adequate heat dissipation within the specified junction temperature limits.

Part Context

This part belongs to the 1N4678UR-1 through 1N4717UR-1 series of 0.5 watt Zener diodes. The series offers a voltage selection range from 1.8 to 43 volts. Standard tolerances are ±5%, with tighter options available. The package serves as a surface mount alternative to the traditional axial DO-35 leaded configuration.

Replacement Considerations

Direct replacements include other 1N4698 variants such as 1N4698UR-1 or 1N4698-1. Verify that substitute parts match the DO-213AA package dimensions and electrical characteristics. Check for compatibility regarding RoHS compliance and tolerance levels before implementation.
