1N4753UR-1

Overview

The Microchip Technology 1N4753UR-1 is a surface mount Zener diode housed in the DO-213AA (MELF) glass package. It provides a nominal Zener voltage of 36 V with a power dissipation rating of 1 W and a tolerance of ±5%. The device operates within a temperature range of -65°C to +175°C, featuring a maximum reverse leakage current of 100 nA at 27.4 V and a Zener impedance of 50 Ohms.

Feature Summary

• Surface mount construction utilizing a glass MELF package for compact integration
• High thermal stability supporting operation up to +175°C
• Internally metallurgically bonded die structure for enhanced reliability

Applications

• Voltage regulation circuits requiring stable reference levels
• Overvoltage protection stages in electronic systems
• Clamping applications in signal processing paths

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical tolerances and screening levels. Ensure the procurement channel sources directly from authorized distributors to guarantee component authenticity and traceability. Confirm RoHS compliance status as required by project specifications before finalizing orders.

Selection Notes

Select this component when a 1 W surface mount Zener regulator is required for high-temperature environments. The DO-213AA package offers a footprint alternative to traditional axial leads while maintaining robust mechanical integrity. Evaluate the 50 Ohm impedance and 100 nA leakage characteristics against circuit sensitivity requirements.

Part Context

This part belongs to the 1N47xx series of Zener diodes manufactured by Microchip Technology. The series encompasses various voltage ratings within the same physical form factor, allowing designers to standardize on a single package type across multiple designs. The UR-1 suffix typically denotes specific manufacturing or screening variations within the commercial product line.

Replacement Considerations

The 1N4753AUR/TR is documented as a parameter-equivalent substitute within the Microchip portfolio.
