1N4747AP/TR8

Overview

The Microchip Technology 1N4747AP/TR8 is a 1.0 W Zener diode with a nominal voltage of 20 V and a tolerance of ±5%. It utilizes an axial DO-41 package and operates within a temperature range of -65°C to +175°C. The device features a maximum reverse leakage current of 100 nA, a Zener impedance of 22 Ohms, and a test current of 12.5 mA.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Offers flexible axial-lead mounting terminals for through-hole integration
• Ensures non-sensitivity to electrostatic discharge (ESD) per MIL-STD-750 Method 1020

Applications

• Voltage regulation in electronic circuits
• Reference voltage sources
• Overvoltage protection

Procurement Notes

Verify the specific suffix 'TR8' against official Microchip documentation to confirm reel packaging specifications. Ensure the component meets required environmental standards and screening levels for the intended application before procurement.

Selection Notes

Select this component for applications requiring a 20 V reference with ±5% tolerance. Consider the DO-41 package size and thermal characteristics relative to the system's power dissipation requirements and available board space.

Part Context

This part belongs to the 1N4728A to 1N4764A series of 1.0 W Zener diodes manufactured by Microchip Technology. The series provides a wide selection of voltages from 3.3 V to 100 V, with various tolerance options identified by different suffix letters.

Replacement Considerations

Surface mount equivalents are available as SMAJ4747A or MLL4747A. RoHS compliant versions may be identified by an 'e3' suffix.
