1N4758PE3/TR8

Single Zener Diodes Overview

The Microchip Technology 1N4758PE3/TR8 is a silicon 1.0-watt Zener diode housed in a plastic DO-41 (DO-204AL) axial lead package. It provides voltage regulation with a nominal Zener voltage of 56 volts and a standard tolerance of ±5%. The device features a maximum dynamic impedance of 110 ohms at the test current of 4.5 mA, with a maximum reverse leakage current of 5 µA at 50 V. It operates within a temperature range of -65°C to +150°C and includes RoHS compliance indicated by the 'e3' suffix.

Single Zener Diodes 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

Single Zener Diodes Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in power supply designs
• General-purpose voltage regulation tasks in electronic equipment

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required specifications. The 'P' indicates plastic construction, while 'TR' denotes tape and reel packaging. Confirm the 'e3' suffix ensures RoHS compliance. Ensure the component meets the specific voltage tolerance and thermal requirements for your application before procurement.

Single Zener Diodes Selection Notes

Select this component when a 56-volt regulation point is needed in a high-power dissipation environment. The plastic DO-41 package offers lower thermal resistance compared to glass-body options. Consider the ±5% tolerance and 110-ohm dynamic impedance characteristics to ensure compatibility with circuit stability requirements.

Single Zener Diodes Part Context

This part belongs to the 1N4728AP through 1N4764AP series of 1.0-watt Zener diodes manufactured by Microsemi (now Microchip Technology). The series covers a wide voltage selection from 3.3 to 100 volts. The 1N4758 variant specifically targets the 56-volt regulation segment within this extensive lineup of JEDEC registered devices.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other 1N4758 variants from different manufacturers, such as the 1N4758A-TP from Micro Commercial Components. Verify that replacement parts match the 1W power rating, DO-41 package, and 56V Zener voltage specifications.
