1N4753APE3/TR8

Overview

The Microchip Technology 1N4753APE3/TR8 is a silicon planar Zener diode in the 1N4728AP through 1N4764AP series, housed in a plastic DO-41 (DO-204AL) axial lead package. It provides voltage regulation with a nominal Zener voltage of 36 V and a standard tolerance of ±5%. The device dissipates up to 1.0 W at 25°C ambient temperature, with a maximum operating temperature of +150°C. Electrical characteristics include a test current of 7.0 mA, a maximum dynamic impedance of 50 Ω, and a maximum reverse current of 5 µA at 27.4 V. The component is RoHS compliant and moisture classified as Level 1.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range.
• Features flexible axial-lead mounting terminals for through-hole applications.
• Constructed with a void-free transfer molded thermosetting epoxy body meeting UL94V-0 flammability standards.
• Offers lower thermal resistance compared to glass-body options within the same JEDEC part numbers.

Applications

• Voltage regulation circuits requiring precise reference levels.
• Protection against overvoltage conditions in electronic systems.
• Clipping and clamping applications in signal processing.

Procurement Notes

Verify that the ordering suffix matches the required specifications. The 'e3' suffix indicates RoHS compliance, while 'TR' denotes tape and reel packaging. Confirm the manufacturer origin, as this component was originally developed by Microsemi before its acquisition by Microchip Technology. Ensure the requested quantity aligns with the standard tape and reel packaging requirements specified by the supplier.

Selection Notes

Select this component when a 36 V reference with ±5% tolerance is required in an axial lead package. The plastic construction offers lower thermal resistance than glass equivalents. Consider the 1.0 W power dissipation limit and derating curves for high-temperature environments. Verify compatibility with existing PCB footprints designed for the DO-41 package style.

Part Context

This device belongs to the popular 1N4728AP through 1N4764AP series of 1.0 watt Zener diodes produced by Microsemi's Scottsdale Division. The series covers a wide voltage selection from 3.3 to 100 volts. The specific part utilizes a plastic encapsulation which distinguishes it from the glass-body (G suffix) variants also available from the manufacturer.

Replacement Considerations

Direct substitutes within the same series include other 1N47xxAJEDEC types with matching voltage ratings. For equivalent performance in plastic packages, verify availability of 1N4753AP or 1N4753APE3 from authorized distributors. Military screening prefixes such as MX are available for enhanced reliability requirements.
