1N4753AG/TR

Overview

The Microchip Technology 1N4753AG/TR is a single Zener diode rated at 36 V nominal voltage with a ±5% tolerance. It features a maximum power dissipation of 1 W and operates within an extended temperature range from -65 °C to +175 °C. The device utilizes an axial DO-41 through-hole package, ensuring robust mechanical stability for industrial applications. Key electrical characteristics include a maximum reverse leakage current of 100 nA and a Zener impedance of 22 Ohms at the specified test current.

Feature Summary

• Extended high-temperature operational capability up to 175 °C
• High power dissipation rating of 1 W in axial packaging
• Low reverse leakage current for stable regulation

Applications

• Voltage reference circuits requiring high thermal stability
• Overvoltage protection in industrial control systems
• Power supply regulation in harsh environments

Procurement Notes

Verify the specific suffix AG against official Microchip documentation to confirm exact manufacturing lot attributes and compliance status. Confirm RoHS designation as non-compliant based on available data. Validate package dimensions and lead form factors prior to PCB layout finalization to ensure mechanical fit.

Selection Notes

Select this component when high power handling and wide temperature operation are required in a standard axial package. Compare Zener impedance and leakage specifications against circuit requirements. Ensure the 1 W power rating accommodates peak dissipation scenarios without exceeding thermal limits.

Part Context

This part belongs to the 1N47xx series of Zener diodes manufactured by Microchip Technology.
