1N4698UR-1E3

Overview

The Microchip Technology 1N4698UR-1E3 is a 500 mW surface mount Zener voltage regulator in the DO-213AA (MELF) package. It provides an 11 V nominal Zener voltage with a standard ±5% tolerance and a test current of 50 µA. The device features a hermetically sealed glass construction with internal metallurgical bonding for high reliability. Maximum ratings include a junction temperature range of -65°C to +175°C, steady-state power dissipation of 0.5 W, and a maximum reverse leakage current of 0.05 µA.

Feature Summary

• Hermetically sealed glass DO-213AA surface mount package
• Internal metallurgical bond between metal slugs and silicon die
• RoHS compliant commercial grade availability

Applications

• Voltage regulation over broad operating current and temperature ranges
• ESD protection applications requiring non-sensitive characteristics per MIL-STD-750 method 1020
• Radiation-hardened circuit designs

Procurement Notes

Verify that the specific ordering suffix matches the required RoHS compliance status, as the e3 suffix indicates RoHS compliance available only on commercial grade devices. Confirm the voltage tolerance requirement, as tighter tolerances require different suffixes. Ensure the procurement channel supports the manufacturer's screening options if military-grade reliability referencing MIL-PRF-19500 is necessary.

Selection Notes

Select this component when a surface mount equivalent to the JEDEC registered 1N4678 series is required. The DO-213AA package offers a compact footprint suitable for automated assembly. Consider the low capacitance characteristic for high-speed applications. Verify that the 500 mW power dissipation rating aligns with the thermal design constraints of the target PCB layout.

Part Context

This part belongs to the 1N4678UR-1 through 1N4717UR-1 series of 0.5 watt glass surface mount Zener diodes. The series covers a voltage selection from 1.8 to 43 volts. These devices serve as the surface mount counterpart to the axial-leaded 1N4678-1 through 1N4717-1 series, maintaining similar electrical characteristics and reliability standards within a MELF-style package.

Replacement Considerations

The 1N4698UR-1 is the non-RoHS version of this component. For axial leaded equivalents, the 1N4698-1 serves as the through-hole alternative.
