1N4702C

Overview

The Microchip Technology 1N4702C is a silicon epitaxial planar Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 15V with a tight tolerance of ±2%. The device operates in the through-hole DO-7 (DO-35) axial package and dissipates up to 0.5W of power. It is registered under the JEDEC 1N4678 through 1N4717 series, ensuring standardized performance characteristics for electronic circuit design.

Feature Summary

• Features internal metallurgical bond construction for enhanced reliability
• Provides tighter voltage tolerances compared to standard variants
• Utilizes silicon epitaxial planar technology for stable operation

Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection in low-power electronic systems
• General-purpose voltage regulation in consumer electronics

Procurement Notes

Verify that the specific order matches the required tolerance grade, as the 1N4702C designation typically implies the 2% variant. Confirm package compatibility with DO-7 or DO-35 footprints during integration. Ensure compliance with relevant environmental standards if RoHS exemption is not applicable for the specific manufacturing lot.

Selection Notes

Select this component when a 15V regulation point is required with high precision. The 2% tolerance makes it suitable for sensitive analog circuits where voltage drift must be minimized. Consider the 0.5W power rating to ensure adequate thermal headroom in the final assembly environment.

Part Context

This part belongs to the widely recognized 1N47xx series of Zener diodes, which are industry-standard components for basic voltage regulation. The 'C' suffix often denotes specific tolerance or packaging variations within the Microchip portfolio, distinguishing it from standard 5% tolerance versions found in general inventory.

Replacement Considerations

Equivalent parts include Vishay 1N4702A and ON Semiconductor 1N4702A, provided they meet the 2% tolerance requirement. Verify that substitute devices support the same DO-7 axial package and 0.5W power dissipation rating to maintain mechanical and thermal integrity.
