1N3155AE3

Single Zener Diodes Overview

The Microchip Technology 1N3155AE3 is a temperature-compensated Zener reference diode belonging to the 1N3154 through 1N3157A series. It provides an 8.4 V nominal voltage with extremely low temperature coefficients, achieving values as low as 0.001% per degree Celsius for minimal voltage drift. Designed for operation at 10.0 mA, this component utilizes a glass axial-leaded DO-7 (DO-204AA) package. The 'e3' suffix indicates RoHS compliance. These devices are engineered to offer high precision and stability in applications requiring accurate voltage references over varying thermal conditions.

Single Zener Diodes Feature Summary

• Provides zero-temperature-coefficient reference characteristics for stable voltage output
• Utilizes glass axial-leaded DO-7 packaging for through-hole mounting
• Ensures RoHS compliance for environmental safety standards

Single Zener Diodes Applications

• Precision voltage reference circuits
• Temperature-compensated power supply designs
• High-stability analog signal conditioning

Single Zener Diodes Procurement Notes

Verify the specific temperature coefficient grade required for your application, as the series offers variations. Confirm that the DO-7 axial leaded package aligns with your PCB layout constraints. Ensure the operating current of 10.0 mA matches your circuit design parameters. Check for any military qualification requirements if the standard commercial version does not suffice.

Single Zener Diodes Selection Notes

Select this component when a highly stable 8.4 V reference is needed with minimal thermal drift. Compare against other series members like 1N3154 or 1N3156 if different voltage levels are acceptable. Consider the DO-7 package size relative to available board space. Verify that the 10.0 mA operating current fits within your power budget and biasing capabilities.

Single Zener Diodes Part Context

This part belongs to the established 1N3154 through 1N3157A family of Zero-TC Reference Diodes produced by Microchip Technology. The series is known for providing selectable nominal voltages around 8.4 V with exceptional temperature stability. The 1N3155AE3 specifically denotes the RoHS-compliant version of the 1N3155 device, maintaining the historical performance characteristics while meeting modern environmental regulations.

Single Zener Diodes Replacement Considerations

Direct substitutes include other members of the 1N3154-1N3157A series if voltage tolerance allows. Military-grade equivalents such as JAN, JANTX, or JANTXV versions may be used if higher reliability is required. Generic 8.4 V Zener diodes lack the specific temperature compensation features and should only be considered if stability requirements are relaxed.
