1N4753CPE3/TR12

Overview

The Microchip Technology 1N4753CPE3/TR12 is a silicon 1.0-watt 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 tight tolerance of ±2%, indicated by the 'C' suffix. The device operates within a temperature range of -65°C to +150°C and features RoHS compliance via the 'e3' suffix. Packaged in tape and reel format per EIA-296 standards, it offers lower thermal resistance compared to glass-body options.

Feature Summary

• Provides precise voltage regulation with ±2% tolerance for stable reference applications
• Utilizes void-free transfer molded thermosetting epoxy body meeting UL94V-0 standards
• Features flexible axial-lead terminals solderable per MIL-STD-750 method 2026
• Non-sensitive to electrostatic discharge per MIL-STD-750 Method 1020

Applications

• Voltage regulation over broad operating current and temperature ranges
• Precision reference circuits requiring tight voltage tolerances
• Power supply protection and clamping applications

Procurement Notes

Verify that the ordering suffixes correctly identify the component specifications. The 'C' suffix confirms the 2% voltage tolerance, while 'P' indicates plastic construction and 'e3' denotes RoHS compliance. The 'TR12' suffix specifies the tape and reel packaging format. Ensure compatibility with existing assembly processes regarding lead plating and moisture sensitivity classification Level 1 requirements.

Selection Notes

Select this component when a 36 V Zener voltage with high precision is required. The ±2% tolerance distinguishes it from standard 5% or 10% variants. Consider the plastic DO-41 package for lower thermal resistance compared to glass equivalents. Verify that the 1.0 W power dissipation rating and operating temperature range meet the specific circuit thermal management needs.

Part Context

This part belongs to the widely used 1N4728A through 1N4764A series of 1.0 Watt Zener diodes. The series offers an extensive voltage selection from 3.3 to 100 volts. While standard versions have 5% tolerance, suffixes like 'C' provide tighter 2% accuracy. The plastic encapsulated version offers advantages in thermal performance and moisture handling compared to older glass-body designs.

Replacement Considerations

Direct substitutes include other manufacturers' 1N4753C devices in DO-41 packages. For equivalent electrical characteristics, verify the 36 V nominal voltage, 2% tolerance, and 1 W power rating. Surface mount equivalents such as SMAJ4753A are available but require different mounting considerations.
