1N5946B

Single Zener Diodes Overview

The Microchip Technology 1N5946B G is a 75 V Zener diode from the 1N5913BG-1N5956BG series, housed in a DO-41 axial leaded package. It provides voltage regulation with a 5% tolerance and a rated power dissipation of 1.5 W. The device features hermetically sealed glass encapsulation with tungsten slugs for high reliability and radiation hardness.

Single Zener Diodes Feature Summary

• Hermetically sealed glass body construction with metallurgically enhanced internal contact design
• Inherently radiation hard characteristics suitable for demanding environments
• Non-sensitive to electrostatic discharge per MIL-STD-750 method 1020

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• High reliability applications requiring hermetic sealing
• Radiation-hardened circuit designs

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against the datasheet nomenclature to ensure correct tolerance and compliance levels. Confirm that the required screening level matches the intended application environment. Check for RoHS compliance requirements if applicable to the commercial grade version.

Single Zener Diodes Selection Notes

Select this component when a 75 V regulation point with 5% tolerance is required in an axial leaded form factor. Consider the hermetic seal and radiation hardness for aerospace or defense use cases. Ensure thermal management aligns with the specified junction-to-ambient resistance values.

Single Zener Diodes Part Context

This part belongs to the 1N5913B through 1N5956B JEDEC registered series manufactured by Microsemi (now Microchip). The series offers a wide voltage range from 3.3 V to 200 V with various tolerance options available in both glass and plastic packages.

Single Zener Diodes Replacement Considerations
