1N4698

Overview

The Microchip Technology 1N4698 is a single Zener diode voltage regulator designed for through-hole mounting in the DO-35 axial leaded package. It provides an 11 V nominal Zener voltage with a standard tolerance of ±5%. The device dissipates up to 500 mW and operates within a temperature range of -65°C to +200°C. Key electrical characteristics include a maximum reverse leakage current of 50 nA, a test current of 50 µA, and a Zener current of 21.6 mA.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features internal metallurgical bond construction for high reliability
• Offers tight voltage tolerances with guaranteed maximum voltage regulation

Applications

• Voltage regulation in electronic circuits
• Reference voltage sources
• Overvoltage protection

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheets. Confirm package type matches DO-35 specifications. Ensure operational parameters align with system requirements. Check RoHS compliance status as indicated in product documentation. Validate supplier authorization before purchase.

Selection Notes

Select this component when an 11 V reference is required in a through-hole design. Consider the 500 mW power dissipation limit for thermal management. Verify that the ±5% tolerance meets circuit accuracy needs. Ensure the wide operating temperature range suits the application environment.

Part Context

This part belongs to the JEDEC registered 1N4678 through 1N4717 series of 0.5 W glass axial-leaded Zener diodes. The series offers a selection from 1.8 to 43 volts. Variants with tighter tolerances or military screening are available via specific suffixes or prefixes.

Replacement Considerations

Equivalent parts include other manufacturers' 1N4698 variants. Cross-reference with 1N4698C for tighter tolerance options. Verify pinout and package dimensions match DO-35 standards before substitution.
