SG1503Y-DESC

Overview

The SG1503Y-DESC is a high-reliability three-terminal voltage reference manufactured by Microchip Technology. It provides a fixed output voltage of 2.5 V with a tolerance of ±1%. The device is housed in an 8-pin ceramic dual in-line package (CERDIP) designed for through-hole mounting. It operates within a temperature range from -55°C to +125°C, ensuring stability in demanding environments.

Feature Summary

• Provides a stable 2.5 V reference output
• Constructed in a hermetically sealed ceramic DIP package
• Qualified for extended industrial and military temperature ranges

Applications

• High-reliability analog signal conditioning circuits
• Precision measurement instrumentation requiring stable references
• Military and aerospace electronic systems

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm pinout and electrical characteristics. Confirm that the CERDIP package matches the target PCB footprint requirements. Ensure the component meets the necessary environmental qualification standards for the intended deployment environment before finalizing procurement.

Selection Notes

Select this component when a precise 2.5 V reference is required in a ruggedized ceramic package. It is suitable for applications where standard plastic packages are insufficient due to thermal or mechanical stress. Consider the through-hole mounting style and the specific operating temperature range constraints of the system design.

Part Context

This part belongs to Microchip's portfolio of high-reliability linear devices. It serves as a precision reference source within power management and signal processing subsystems. The device supports designs requiring long-term stability and resistance to harsh environmental conditions typical of defense and industrial sectors.

Replacement Considerations

Consult official substitution lists for compatible alternatives. Verify that any substitute maintains the 2.5 V output, ±1% tolerance, and 8-pin CERDIP form factor.
