1N4753CP/TR8

Overview

The Microchip Technology 1N4753CP/TR8 is a silicon 1-watt Zener diode in the 1N4728AP through 1N4764AP series. It provides voltage regulation with a nominal Zener voltage of 36 V and a tight tolerance of ±2%, indicated by the 'C' suffix. The device operates within a temperature range of -65°C to +150°C and features a plastic DO-41 (DO-204AL) axial-lead package. 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 precise voltage regulation with a ±2% tolerance on the nominal Zener voltage.
• Utilizes a void-free transfer molded thermosetting epoxy body for moisture resistance.
• Features flexible axial-lead mounting terminals suitable for standard through-hole applications.
• Offers robust performance across a broad operating current and temperature range.

Applications

• Voltage reference circuits requiring high precision.
• Overvoltage protection in electronic systems.
• General-purpose voltage regulation tasks.

Procurement Notes

Verify that the ordering suffix matches the required specifications. The 'P' indicates plastic construction, while 'TR' denotes tape and reel packaging. Confirm the 'C' suffix corresponds to the necessary ±2% voltage tolerance. Ensure the manufacturer designation aligns with project requirements, as this component originates from the Microsemi Scottsdale Division, now part of Microchip Technology.

Selection Notes

Select this component when a 36 V regulation point with tighter than standard tolerance is required. The plastic DO-41 package offers lower thermal resistance compared to glass-body options. Consider the ±2% tolerance if standard 5% or 10% variations are insufficient for circuit accuracy. Verify compatibility with the intended PCB layout for axial leads.

Part Context

This component belongs to the popular 1N4728A through 1N4764A series of 1.0 watt Zener diodes. The series covers a voltage selection from 3.3 to 100 volts. The specific model utilizes a plastic encapsulated body, distinguishing it from glass-body variants. It is JEDEC registered and available in various screening levels.

Replacement Considerations

Surface mount equivalents such as SMAJ4753A or MLL4753A are available. Other manufacturers may offer generic 1N4753 replacements, but verify tolerance and package dimensions match the original design constraints.
