1N4750CE3/TR13

Overview

The Microchip Technology 1N4750CE3/TR13 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 27 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 as denoted by the 'TR13' suffix, it offers flexible mounting terminals and void-free transfer molded epoxy construction.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for standard through-hole integration
• 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 precise reference voltages
• Power supply protection and clamping applications
• General-purpose electronic equipment utilizing axial-lead components

Procurement Notes

Verify that the ordering suffixes align with specific requirements: 'C' confirms the 2% voltage tolerance, 'e3' ensures RoHS compliance, and 'TR13' indicates tape and reel packaging. Confirm the manufacturer designation, as the datasheet originates from Microsemi, now part of Microchip Technology. Ensure the component matches the JEDEC registered type number for electrical characteristics validation.

Selection Notes

Select this component when a 27 V Zener voltage with high precision is required. The ±2% tolerance makes it suitable for applications where tighter control than standard 5% or 10% variants is necessary. The plastic DO-41 package offers lower thermal resistance compared to glass-body options, while the 1.0-watt power dissipation rating supports steady-state operation at elevated temperatures.

Part Context

This device belongs to the popular 1N4728A through 1N4764AP series of 1.0-watt Zener diodes. The series covers an extensive voltage selection from 3.3 to 100 volts. The 'P' suffix designates the plastic encapsulated version, which provides improved thermal performance over glass-body alternatives. The 'e3' suffix denotes RoHS compliant devices available from the manufacturer.

Replacement Considerations

Surface mount equivalents are available as SMAJ4750A and MLL4750A. For higher reliability requirements, military screening levels such as JAN, JANTX, JANTXV, and JANS are available by adding MQ, MX, MV, or MSP prefixes respectively.
