1EZ100D10/TR12

Overview

The 1EZ100D10/TR12 is a silicon Zener diode manufactured by Microsemi Corporation. It provides voltage regulation with a nominal Zener voltage of 100 V and a maximum power dissipation of 1 W. The device features a standard voltage tolerance of ±10%, indicated by the '10' suffix in the part number. It is housed in a DO-204AL (DO-41) axial-leaded plastic package and supplied in tape and reel packaging.

Feature Summary

• Provides stable voltage regulation within the specified series range
• Encapsulated in a durable plastic axial-leaded package for through-hole mounting
• Designed for operation at full power rating with adequate heat sinking

Applications

• General purpose voltage regulation circuits
• Power supply reference voltage generation
• Over-voltage protection stages

Procurement Notes

Verify the specific suffix '10' confirms the ±10% tolerance requirement for your design. Confirm that the DO-204AL package orientation matches your PCB footprint. Ensure thermal management strategies account for the 1 W power dissipation limit under worst-case operating conditions to maintain reliability.

Selection Notes

Select this component when a 100 V regulation point with moderate precision is required. The plastic construction offers cost advantages over glass equivalents, though it may have lower thermal resistance limits. Consider tighter tolerance variants if the ±10% variance exceeds circuit specifications.

Part Context

This part belongs to the 1EZ series of 1 Watt Zener Diodes from Microsemi. The series covers a wide voltage selection range using standardized JEDEC numbering conventions adapted for plastic encapsulation. The '1EZ' prefix identifies the specific power class and manufacturer family within their discrete semiconductor portfolio.

Replacement Considerations

Equivalent parts include other 100 V, 1 W Zener diodes in the DO-41 package. Verify that replacement devices meet the same ±10% tolerance and thermal characteristics. Cross-reference with generic industry equivalents only if electrical parameters match exactly.
