Overview
The Microchip Technology 1N4700UR-1 is a surface-mount Zener diode designed for voltage regulation applications. It utilizes the DO-213AA-2 package and operates within an extended temperature range from -65°C to +175°C junction temperature. The device provides a nominal Zener voltage of 3.3 V with a 5% tolerance, dissipating up to 500 mW of power. Key electrical characteristics include a maximum reverse leakage current of 50 nA at 2.8 V, a test current of 50 µA, and a forward voltage of 1.1 V at 200 mA.
Feature Summary
- Extended operating temperature capability suitable for harsh environments
- Surface-mount construction for automated assembly integration
- Temperature-compensated design for stable voltage reference performance
Applications
- Voltage regulation in industrial control systems
- Over-voltage protection circuits
- Reference voltage generation in precision measurement equipment
Procurement Notes
Verify component authenticity through authorized Microchip distributors or certified supply chain partners. Confirm that the received parts match the specific DO-213AA-2 package marking and lot traceability requirements. Ensure storage conditions comply with manufacturer guidelines to prevent moisture sensitivity damage prior to soldering.
Selection Notes
Select this component when a low-voltage Zener reference is required in a compact surface-mount form factor. The wide thermal operating range distinguishes it from standard commercial-grade alternatives. Verify that the 500 mW power dissipation rating aligns with the thermal management capabilities of the target printed circuit board layout.
Part Context
This part belongs to the 1N47xx series of Zener diodes manufactured by Microchip Technology. The UR-1 suffix indicates a specific surface-mount variant packaged in the DO-213AA-2 footprint. This series is widely utilized in electronic designs requiring reliable voltage clamping and regulation across diverse industrial and commercial sectors.
Replacement Considerations
Direct functional equivalents may include other manufacturers' 1N4700 variants in DO-213AA packages. Cross-referencing requires matching the 3.3 V Zener voltage, 500 mW power rating, and 5% tolerance specifications.
