1EZ100D2/TR12

Overview

The 1EZ100D2/TR12 is a silicon Zener diode manufactured by Microsemi Corporation, designed for voltage regulation applications. It features a nominal Zener voltage of 100 V with a tight tolerance of ±2%. The device is rated for a maximum power dissipation of 1 W and operates within an extended temperature range from -65°C to +150°C. Packaged in the DO-204AL (DO-41) axial leaded plastic housing, it supports through-hole mounting. The component is supplied in tape and reel packaging, facilitating automated assembly processes.

Feature Summary

• Provides precise voltage regulation with a nominal Zener voltage of 100 V and a tight ±2% tolerance.
• Capable of handling a maximum power dissipation of 1 W for stable operation under load.
• Engineered for reliable performance across an extended operating temperature range from -65°C to +150°C.
• Utilizes a standard DO-204AL (DO-41) axial plastic package suitable for through-hole integration.

Applications

• Precision voltage reference circuits requiring stable DC levels
• Overvoltage protection stages in sensitive electronic systems
• Power supply output regulation modules

Procurement Notes

Verify the specific suffix 'D2' confirms the ±2% tolerance variant, as other suffixes indicate different tolerances. Confirm RoHS compliance status, as standard versions may not meet current environmental directives. Ensure the TR12 designation matches the required tape and reel quantity for your manufacturing line. Cross-reference the manufacturer's latest datasheet for any updates on screening levels or material changes.

Selection Notes

Select this component when a 100 V Zener voltage with high precision (±2%) is required. The 1 W power rating suits moderate current applications without excessive heat sinking. The wide temperature range makes it suitable for harsh environments. Compare against lower tolerance options if tighter stability is needed, or higher power variants for increased thermal loads.

Part Context

This part belongs to the Microsemi 1EZ series of axial-leaded Zener diodes. The series offers various voltage selections and tolerance options, identified by suffix codes. The 1EZ100D2 specifically denotes the 100 V version with 2% tolerance. These diodes are widely used in industrial and commercial electronics where reliable voltage clamping is essential.

Replacement Considerations

Check for direct equivalents such as JAN1N5239B or similar military-grade parts if higher reliability screening is required. Verify pinout compatibility with the DO-41 package. Ensure replacement parts match the 100 V Zener voltage and ±2% tolerance specifications.
