1N4753AUR/TR

Overview

The Microchip Technology 1N4753AUR/TR is a surface mountable 1.0 W glass Zener diode in the DO-213AB MELF package. It features a nominal Zener voltage of 36 V with a standard tolerance of ±5%. The device operates within a temperature range of -65°C to +175°C and has a maximum reverse current of 5 µA at 27.4 V. Electrical characteristics include a test current of 7.0 mA, a maximum dynamic impedance of 50 Ohms, and a forward voltage of 1.2 V at 200 mA.

Feature Summary

• Hermetically sealed glass MELF package suitable for high reliability applications
• Surface mount design ideal for high density mounting with low parasitic requirements
• Inherently radiation hard per MicroNote 050
• Regulates voltage over a broad operating current and temperature range

Applications

• Voltage regulation in high density electronic circuits
• High reliability applications requiring source control drawings
• Radiation-hardened circuit designs

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm packaging and compliance details. Confirm that the TR suffix indicates tape and reel packaging as specified in the datasheet. Ensure compatibility with the DO-213AB footprint during procurement planning.

Selection Notes

Select this component for applications requiring a 36 V reference in a surface mount form factor. Consider the ±5% voltage tolerance and 1 W power dissipation capabilities. Verify thermal management requirements given the junction-to-ambient thermal resistance specifications on FR4 PCBs.

Part Context

This part belongs to the 1N4728AUR through 1N4764AUR series of surface mount Zener diodes. It serves as the DO-213AB equivalent to the axial-leaded 1N4753A registration. The series offers a wide selection of voltages from 3.3 V to 100 V with various tolerance options.

Replacement Considerations

The 1N4753AUR/TR is parameter-equivalent to the 1N4753AUR. Both are surface mount equivalents to the axial 1N4753A.
