1N4754CPE3/TR8

Overview

The Microchip Technology 1N4754CPE3/TR8 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 39V 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-compliant annealed matte-tin plating on its terminals, designated by the 'e3' suffix. Packaged in tape and reel format per EIA-296 standards as indicated by the 'TR8' suffix, it offers lower thermal resistance compared to glass-body options.

Feature Summary

• Provides precise voltage regulation with a standard ±2% tolerance for stable reference applications
• Features flexible axial-lead mounting terminals suitable for through-hole PCB integration
• Constructed with void-free transfer molded thermosetting epoxy meeting UL94V-0 flammability ratings
• Includes RoHS compliant annealed matte-tin plating on terminals for solderability

Applications

• Voltage regulation over broad operating current and temperature ranges
• General purpose clipping and clamping circuits
• Protection against voltage transients in electronic systems

Procurement Notes

Verify that the ordering suffix matches the required specifications: 'C' indicates a 2% voltage tolerance, 'P' denotes plastic construction, 'e3' confirms RoHS compliance, and 'TR8' specifies the tape and reel packaging quantity. Confirm the manufacturer origin, as this part originates from the Microsemi Scottsdale Division now under Microchip Technology. Ensure the component meets the specific moisture classification level 1 requirements without needing dry pack storage.

Selection Notes

Select this component when a 39V Zener voltage with high precision is required in a 1-watt power dissipation class. The plastic DO-41 package offers lower thermal resistance than glass equivalents. Consider the ±2% tolerance if tighter voltage stability is needed compared to the standard 5% or 10% variants. Verify that the axial lead form factor aligns with the target printed circuit board layout and assembly process.

Part Context

This device belongs to the popular 1N4728A through 1N4764A series of 1.0-watt Zener diodes registered with JEDEC. The series covers a wide voltage selection from 3.3 to 100 volts. While originally manufactured by Microsemi's Scottsdale Division, these parts are now supported by Microchip Technology. The series includes various tolerance options identified by suffix letters, such as 'A' for 5% and 'C' for 2%.

Replacement Considerations

Surface mount equivalents are available as SMAJ4754A and MLL4754A. Consult the factory for other surface mount options or military screening levels requiring JAN, JANTX, JANTXV, or JANS prefixes.
