1N4702UR-1

Overview

The 1N4702UR-1 is a Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 15 V with a tolerance of ±5%. The device has a power dissipation rating of 500 mW and operates in the DO-213AA (SOD-80) surface-mount package. It is constructed from silicon and supports a maximum operating temperature of 200 °C.

Feature Summary

• Provides stable voltage regulation via Zener breakdown characteristics
• Utilizes hermetically sealed glass construction for environmental protection
• Designed for surface-mount installation using the DO-213AA package

Applications

• Voltage reference circuits
• Overvoltage protection
• Clamping applications

Procurement Notes

Verify component authenticity through authorized Microchip distributors or direct channels. Confirm datasheet revisions match design requirements. Ensure storage conditions comply with manufacturer guidelines to maintain hermetic seal integrity. Validate RoHS status if restricted substances are prohibited in the target application.

Selection Notes

Select this component when a 15 V regulation point is required in a compact surface-mount form factor. The DO-213AA package suits automated assembly processes. Consider the 500 mW power limit and thermal management needs for the specific circuit environment before implementation.

Part Context

This part belongs to the 1N47xx series of Zener diodes produced by Microchip Technology. The 'UR' suffix typically denotes a specific package variant, while the '-1' indicates a bulk packaging option. It serves as a surface-mount alternative to traditional axial-lead versions within the same electrical specification family.

Replacement Considerations

Equivalent parts include the 1N4702A in DO-35 packages for through-hole designs. Surface-mount replacements must match the 15 V Zener voltage, 500 mW power rating, and DO-213AA footprint. Verify pinout compatibility and thermal resistance values before substitution.
