1N5944APE3/TR8

Single Zener Diodes Overview

The Microchip Technology 1N5944APE3/TR8 is a 62 V, 1.5 W glass-encapsulated Zener diode in the DO-204AL (DO-41) axial package. It features a ±10% voltage tolerance and operates within a junction temperature range of -65°C to +175°C. The device provides a maximum dynamic impedance of 100 Ohms at a test current of 6.0 mA, with a reverse leakage current of 1 µA at 47.1 V. It includes a RoHS-compliant matte tin over copper terminal finish.

Single Zener Diodes Feature Summary

• Hermetically sealed voidless hard glass construction with tungsten slugs for enhanced reliability.
• Metallurgically enhanced internal contact design providing lower thermal resistance.
• Non-sensitive to electrostatic discharge per MIL-STD-750 method 1020.
• Inherently radiation hard as described in Microsemi MicroNote 050.

Single Zener Diodes Applications

• Voltage regulation across broad operating currents and temperatures.
• High-reliability applications requiring hermetic sealing.
• Radiation-hardened circuit designs.

Single Zener Diodes Procurement Notes

Verify the specific suffix 'TR8' against official documentation, as the datasheet specifies 'TR' for tape and reel packaging. Confirm that the component meets RoHS compliance requirements if applicable to your manufacturing process. Ensure the ordering nomenclature matches the exact JEDEC type number and tolerance level required for your design specifications.

Single Zener Diodes Selection Notes

Select this component when a 62 V Zener voltage with a 10% tolerance is required in an axial leaded package. Consider the 1.5 W power dissipation rating and the wide operating temperature range up to 175°C. Verify compatibility with through-hole mounting processes and ensure the hermetically sealed glass body suits the environmental conditions of the target application.

Single Zener Diodes Part Context

This part belongs to the 1N5913BG–1N5956BG series of 1.5 Watt Glass Zener Diodes. The series offers voltages from 3.3 V to 200 V with various tolerances. The 'G' suffix indicates a glass casing, while 'e3' denotes RoHS compliance. These devices are available in multiple screening levels, including military equivalents referenced to MIL-PRF-19500.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 1N5944 variants such as 1N5944B or 1N5944C, provided they meet the 62 V specification and package requirements. Verify that any substitute maintains the same power dissipation rating and hermetic sealing characteristics if environmental robustness is critical.
