1N4700UR-1/TR

Overview

The Microchip Technology 1N4700UR-1/TR is a single Zener diode voltage regulator housed in the DO-213AA surface-mount package. It features a nominal Zener voltage of 13 V with a 5% tolerance and a maximum power dissipation of 500 mW. The device operates within a temperature range of -65°C to +175°C TJ, with a maximum reverse leakage current of 50 nA at 9.8 V and a forward voltage of 1.5 V at 100 mA.

Feature Summary

• Provides stable voltage regulation using a single Zener junction design
• Supports high-temperature operation up to 175°C junction temperature
• Utilizes compact DO-213AA surface-mount packaging for automated assembly

Applications

• Voltage reference circuits requiring stable DC levels
• Over-voltage protection stages in electronic systems
• Clamping applications in signal processing paths

Procurement Notes

Verify the specific suffix UR-1/TR against official Microchip documentation to confirm tape-and-reel packaging and exact electrical tolerances. Ensure the DO-213AA footprint matches the target PCB layout. Cross-reference datasheet revisions to validate thermal resistance and leakage current specifications for the intended operating environment.

Selection Notes

Select this component when a 13 V regulation point is required in a surface-mount application. Consider the 500 mW power rating and 175°C thermal limit for circuit design. Compare against through-hole alternatives if board space permits, but prioritize this variant for automated SMT production lines requiring consistent reel packaging.

Part Context

This part belongs to the 1N47xx series of Zener diodes manufactured by Microchip Technology. The series offers various voltage ratings in both through-hole and surface-mount packages. The UR-1/TR designation specifically indicates the surface-mount DO-213AA form factor supplied in tape and reel format for high-volume manufacturing efficiency.

Replacement Considerations

Direct substitutes include other manufacturers' 1N4700 variants in DO-213AA packages. Verify that replacement parts match the 13 V Zener voltage, 500 mW power rating, and 5% tolerance. Ensure thermal characteristics and leakage currents are compatible with the original design requirements.
