1N4754E3/TR13

Overview

The Microchip Technology 1N4754E3/TR13 is a silicon 1-watt Zener diode in the 1N4728AP through 1N4764AP series. It provides voltage regulation with a nominal Zener voltage of 39 V and a standard tolerance of ±5%. The device operates within a temperature range of -65°C to +150°C and features a plastic encapsulated DO-41 (DO-204AL) axial-lead package. Electrical characteristics include a maximum dynamic impedance of 60 Ohms at a test current of 6.5 mA, a maximum reverse current of 5 µA at 23 V, and a forward voltage of 1.2 V maximum at 200 mA.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for through-hole applications
• Constructed with a void-free transfer molded thermosetting epoxy body meeting UL94V-0 standards
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack

Applications

• Voltage regulation circuits
• Reference voltage sources
• Overvoltage protection

Procurement Notes

Verify that the ordering suffix TR13 corresponds to the tape and reel packaging option described in the datasheet as adding a TR suffix. Confirm RoHS compliance status associated with the e3 suffix. Ensure the specific part number matches the manufacturer's official documentation for the 1N4754A variant within the specified series.

Selection Notes

Select this component for applications requiring a 39 V reference or regulation point with ±5% tolerance. Consider the 1 W power dissipation rating and thermal resistance values when designing heat management. Verify compatibility with the DO-41 package dimensions and lead spacing requirements of the target PCB layout.

Part Context

This component belongs to the 1N4728AP through 1N4764AP series of silicon 1-watt Zener diodes manufactured by Microsemi, now part of Microchip Technology. The series offers an extensive voltage selection from 3.3 to 100 volts in plastic encapsulated packages. These devices are JEDEC registered and provide options for various screening levels and tighter tolerances depending on the suffix configuration.

Replacement Considerations

Surface mount equivalents are available as SMAJ4754A and MLL4754A. Other variants in the series offer different voltage ratings.
