1N3154E3

Overview

The Microchip Technology 1N3154E3 is an 8.4 V temperature compensated Zener reference diode housed in a hermetically sealed glass DO-7 (DO-204AA) package. It operates at a test current of 10 mA with a nominal voltage range of 8.00 V to 8.80 V. The device features a maximum temperature coefficient of 0.01 %/°C and maintains stability across a temperature range of -55°C to +100°C. Electrical characteristics include a maximum zener impedance of 15 ohms and a reverse current of 10 μA at 5.5 V.

Feature Summary

• Provides minimal voltage changes over a broad temperature range for stable reference applications
• Features internal metallurgical bonds and flexible axial-lead mounting terminals
• Non-sensitive to electrostatic discharge per MIL-STD-750 Method 1020

Applications

• Instrumentation requiring stable voltage references
• Circuit designs demanding minimal voltage change with temperature
• Temperature compensated Zener reference circuits

Procurement Notes

Verify the specific suffix requirements when ordering, as tighter voltage tolerances require hyphenated suffixes appended to the part number. Confirm that the e3 suffix denotes RoHS compliance for commercial products, noting that military qualifications utilize different prefixes and do not apply this suffix. Ensure the operating current is maintained near 10.0 mA for optimal voltage-temperature stability during implementation.

Selection Notes

Select the 1N3154E3 when a standard 8.4 V reference with a 0.01 %/°C temperature coefficient is required. This component is suitable for general commercial applications where hermetic sealing is beneficial. For lower temperature coefficients or military specifications, consider other variants within the 1N3154 through 1N3157 series with appropriate prefixes or suffixes.

Part Context

This component belongs to the popular 1N3154 through 1N3157A series of Zero-TC Reference Diodes manufactured by Microsemi's Scottsdale Division. The series offers a selection of 8.4 V nominal voltages with varying temperature coefficients down to 0.001 %/°C. These devices are JEDEC registered and available in various military qualifications including JAN, JANTX, and JANTXV levels.

Replacement Considerations

Direct replacements include other members of the 1N3154 through 1N3157 series depending on the required temperature coefficient. Variants such as 1N3155, 1N3156, or 1N3157 offer tighter coefficients of 0.005%, 0.002%, and 0.001% respectively. Military equivalents can be identified by adding JAN, JANTX, or JANTXV prefixes.
