1N4753PE3/TR12

Overview

The Microchip Technology 1N4753PE3/TR12 is a silicon 1.0-watt Zener diode in the 1N4728AP through 1N4764AP series, housed in a plastic DO-41 axial lead package. It provides voltage regulation with a nominal Zener voltage of 36 V and a standard tolerance of ±5%. The device operates within a temperature range of -65°C to +150°C and features RoHS-compliant annealed matte-tin plating. Electrical characteristics include a maximum dynamic impedance of 50 Ohms at a test current of 7.0 mA, a maximum reverse current of 5 µA at 27.4 V, and a forward voltage of 1.2 V maximum at 200 mA.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for standard through-hole applications
• Constructed with void-free transfer molded thermosetting epoxy meeting UL94V-0 standards
• Non-sensitive to electrostatic discharge per MIL-STD-750 Method 1020

Applications

• Voltage regulation circuits requiring 36 V reference
• Power supply protection and clamping applications
• General-purpose electronic equipment utilizing axial-lead components

Procurement Notes

Verify that the ordering suffix TR12 corresponds to the tape and reel packaging option as defined by EIA-296 standards. Confirm the specific manufacturer designation, as this part number originates from the Microsemi Scottsdale Division, now part of Microchip Technology. Ensure compliance requirements match the RoHS-compliant e3 suffix specifications provided in the datasheet.

Selection Notes

Select this component when a 36 V Zener voltage with ±5% tolerance is required in a plastic DO-41 package. Consider the 1.0 W power dissipation rating and the thermal resistance of 45 °C/W junction to lead. Verify that the operating environment stays within the specified -65°C to +150°C temperature range and that the moisture classification Level 1 meets storage requirements without dry pack necessity.

Part Context

This device belongs to the JEDEC registered 1N4728A to 1N4764A series of 1.0 watt Zener diodes. The 'P' suffix indicates plastic construction, which offers lower thermal resistance compared to glass-body options. The 'e3' suffix denotes RoHS compliance with tin plating, while 'TR12' specifies the reel packaging format for automated assembly processes.

Replacement Considerations

Consult factory for surface mount equivalents such as SMAJ4753A or MLL4753A. Other variants within the 1N4753 series may exist with different tolerances or packaging options.
