1N3155

Single Zener Diodes Overview

The Microchip Technology 1N3155 is a temperature-compensated Zener reference diode designed for high-precision voltage regulation. It features an 8.4V nominal breakdown voltage with a low temperature coefficient, ensuring minimal voltage drift across varying thermal conditions. The device operates at a test current of 10mA and exhibits a dynamic impedance of 15 Ohms. Housed in a hermetically sealed glass DO-7 (DO-204AA) axial-leaded package, it provides stable performance suitable for critical analog applications requiring reliable reference voltages.

Single Zener Diodes Feature Summary

• Temperature compensated design for minimal voltage change with temperature

Single Zener Diodes Procurement Notes

Verify the specific suffix (e.g., -1, A, e3) to confirm military qualification or RoHS compliance status. Confirm package type matches DO-7 requirements. Check datasheet for exact tolerance grades and temperature coefficient limits before integration. Ensure operating current aligns with the specified 10mA test condition for optimal accuracy.

Single Zener Diodes Selection Notes

Select this component when a stable 8.4V reference is required with strict temperature stability constraints. Compare temperature coefficients against application thermal ranges. Verify package compatibility with existing PCB layouts. Consider alternative voltages within the 1N3154-1N3157 series if different reference levels are needed.

Single Zener Diodes Part Context

Part of the 1N3154 through 1N3157A series of Zero-TC Reference Diodes. Available in JAN, JANTX, and JANTXV military qualifications. Commercial versions may include an e3 suffix for RoHS compliance. Manufactured by Microchip/Microsemi for high-reliability applications.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other parts from the 1N3154-1N3157A series with matching 8.4V nominal voltage. Verify equivalent temperature coefficients and dynamic impedance values. Ensure package style and hermetic sealing requirements are met by the replacement component.
