1N4754PE3/TR8

Overview

The Microchip Technology 1N4754PE3/TR8 is a silicon 1.0-watt Zener diode housed in a plastic DO-41 (DO-204AL) axial lead package. It provides voltage regulation at a nominal Zener voltage of 39 V with a standard tolerance of ±5%. The device operates within a temperature range of -65°C to +150°C and features RoHS-compliant annealed matte-tin plating on its terminals.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for through-hole integration
• Constructed with a void-free transfer molded thermosetting epoxy body meeting UL94V-0 standards
• Non-sensitive to electrostatic discharge per MIL-STD-750 Method 1020

Applications

• Voltage regulation circuits requiring 39 V reference
• Power supply protection and clamping applications
• General-purpose electronic equipment utilizing axial-lead components

Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm tolerance, packaging, and compliance status. Ensure the ordering part number matches the required JEDEC type and mechanical specifications before procurement.

Selection Notes

Select this component for applications requiring a 39 V Zener voltage with ±5% tolerance in a 1 W power dissipation package. Consider the thermal resistance characteristics and operating temperature limits when designing the circuit layout.

Part Context

This part belongs to the 1N4728AP thru 1N4764AP series of 1.0 watt Zener diodes manufactured by Microsemi (now Microchip Technology). The series offers extensive voltage selection from 3.3 to 100 volts in plastic encapsulated packages.

Replacement Considerations

Surface mount equivalents are available as SMAJ4754A or MLL4754A. Consult the manufacturer for other compatible surface mount options or military screening levels.
