1N5916A

Single Zener Diodes Overview

The Microchip Technology 1N5916A is a 4.3 V Zener diode in the 1N5913BG–1N5956BG series, housed in a DO-41 axial package. It provides voltage regulation with a 10% tolerance and a maximum power dissipation of 1.5 W at 25°C ambient temperature. The device operates within a junction temperature range of -65°C to +175°C and features a hermetically sealed glass construction.

Single Zener Diodes Feature Summary

• Hermetically sealed glass encapsulation for high reliability
• Flexible axial-lead mounting terminals
• Metallurgically enhanced internal contact design
• Non-sensitive to electrostatic discharge

Single Zener Diodes Applications

• Voltage regulation over broad operating current ranges
• High reliability applications requiring radiation hardness
• Temperature-stable reference circuits

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against the datasheet nomenclature to confirm tolerance level and RoHS compliance status. Ensure the ordering part number matches the required JEDEC type and screening level. Confirm lead finish options and packaging preferences directly with the manufacturer or authorized distributors prior to purchase.

Single Zener Diodes Selection Notes

Select this component when a stable 4.3 V reference is required in an axial package. Consider the 10% voltage tolerance and 1.5 W power rating for thermal management. Evaluate the hermetic seal benefits for harsh environments compared to plastic alternatives.

Single Zener Diodes Part Context

This device belongs to the 1N5913B through 1N5956B series of 1.5-watt Zener diodes. The series offers a wide voltage selection from 3.3 V to 200 V with various tolerance levels. The 'G' suffix indicates a glass-cased version available from Microsemi/Microchip.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 1N5916 variants with matching voltage and package. Verify tolerance suffixes (A, B, C, D) match requirements. Check if MIL-PRF-19500 screening is necessary for the application.
