1N3155UR-1

Overview

The 1N3155UR-1 is a temperature-compensated Zener voltage reference diode manufactured by Microchip Technology. It features an 8V to 8.8V Zener voltage range with a test current of 10mA and a Zener impedance of 15 Ohms. The device utilizes a round-end package configuration and operates within a wide temperature range, supporting through-hole mounting.

Feature Summary

• Temperature compensated design for stable voltage reference performance across varying thermal conditions
• Round-end package configuration suitable for specific mechanical integration requirements
• Hermetically sealed construction ensuring long-term reliability in demanding environments

Applications

• Precision voltage reference circuits requiring low temperature drift
• Military and aerospace electronic systems necessitating high reliability
• Test and measurement equipment calibration standards

Procurement Notes

Verify the specific suffix UR-1 against official Microchip documentation to confirm the exact package style and testing criteria. Ensure compatibility with existing board layouts due to the round-end form factor. Confirm that the hermetic sealing meets project environmental specifications before finalizing procurement decisions.

Selection Notes

Select this component when a stable voltage reference with minimal temperature coefficient is required in rugged applications. The round-end package distinguishes it from standard axial leads. Verify that the 15 Ohm impedance aligns with circuit noise sensitivity requirements and that the 10mA test current fits the power budget constraints.

Part Context

This part belongs to the JANS series of radiation-hardened and high-reliability semiconductors produced by Microchip. These components are designed for critical missions where standard commercial parts may fail. The 1N3155 family provides precise voltage regulation essential for sensitive analog signal processing in harsh operational environments.
