Overview
The Microchip Technology 1N3154E3/TR is a temperature-compensated Zener reference diode featuring an 8.4 V nominal voltage with a maximum temperature coefficient of 0.01 %/°C. It operates at a test current of 10 mA, providing minimal voltage change across a wide temperature range from -65°C to +175°C. The device utilizes a hermetically sealed glass DO-7 (DO-204AA) axial-leaded package and includes RoHS compliance indicated by the e3 suffix.
Feature Summary
- Provides stable voltage reference with minimal temperature-induced drift
- Hermetically sealed glass construction for environmental protection
- RoHS compliant annealed matte-Tin plating terminals
Applications
- Instrumentation requiring stable voltage references
- Circuit designs demanding low temperature coefficient performance
- Precision analog signal conditioning applications
Procurement Notes
Verify the specific revision level and datasheet version when sourcing this component, as manufacturing processes may evolve. Confirm that the tape and reel packaging aligns with automated assembly requirements. Ensure the supplier provides traceability documentation consistent with commercial grade specifications.
Selection Notes
Select this component when a fixed 8.4 V reference with tight thermal stability is required in a through-hole package. Consider the operating current constraints to maintain optimal voltage-temperature stability. Evaluate the maximum power dissipation limits relative to ambient thermal conditions during circuit design.
Part Context
This part belongs to the 1N3154 series of Zero-TC Reference Diodes manufactured by Microchip Technology. The series offers various military qualifications and tighter tolerance options. The e3 suffix denotes RoHS compliance, while the TR suffix indicates tape and reel packaging availability.
Replacement Considerations
Consult official manufacturer substitution lists for verified equivalents. Verify pinout compatibility and electrical parameter alignment before replacing components in existing designs.
