1N4699E3

Overview

The Microchip Technology 1N4699E3 is a Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 12 V with a 5% tolerance. The device operates in a through-hole DO-35-2 package and dissipates up to 500 mW. It supports an operating temperature range from -65 °C to +175 °C.

Feature Summary

• Provides stable voltage regulation at a nominal 12 V level
• Constructed with internal metallurgical bonding for reliability
• Compatible with RoHS standards

Applications

• Voltage reference circuits
• Overvoltage protection
• General-purpose voltage regulation

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm compliance details and availability status. Confirm that the DO-35 package matches your board layout requirements. Ensure the 500 mW power dissipation rating aligns with your thermal design constraints before finalizing procurement.

Selection Notes

Select this component when a 12 V regulated supply is required in a through-hole configuration. The wide temperature range makes it suitable for industrial environments. Verify that the 5% voltage tolerance meets your circuit precision needs compared to tighter tolerance alternatives.

Part Context

This part belongs to the standard Zener diode family manufactured by Microchip Technology. It utilizes glass encapsulation typical of the DO-35 axial leaded form factor. The E3 suffix indicates lead-free construction compliant with environmental directives.

Replacement Considerations

Consult official substitution lists for equivalent 12 V, 500 mW Zener diodes in DO-35 packages. Verify pinout compatibility and thermal characteristics before replacing.
