Overview
The Microsemi Corporation 1EZ130DE3/TR8 is a unidirectional voltage regulator diode constructed from silicon. It operates within the DO-204AL (DO-41) axial leaded package, which is RoHS compliant. The device provides a nominal Zener voltage of 130 V with a tolerance of 5%. It supports a maximum power dissipation of 1 W and functions reliably across an operating temperature range from -55 °C to +175 °C.
Feature Summary
- Utilizes a hermetically sealed glass construction for enhanced environmental stability
- Features metallurgically bonded internal contacts to ensure high reliability
- Designed for surface mount applications requiring low parasitic characteristics
Applications
- High density circuit designs
- Low parasitic requirement systems
- High reliability applications governed by source control drawings
- Screening in accordance with MIL-PRF-19500 standards
Procurement Notes
Verify that the specific suffix 'TR8' corresponds to the requested tape and reel packaging configuration. Confirm that the component meets all necessary military screening requirements if intended for use under MIL-PRF-19500 guidelines. Ensure the ordering documentation explicitly references the RoHS compliance status associated with the 'E3' designation.
Selection Notes
Select this component when a robust, high-reliability Zener diode is required for harsh environments. The DO-204AL package offers a suitable balance of power handling and mounting flexibility. Consider the metallurgical bonding feature for critical applications where standard epoxy encapsulation may be insufficient.
Part Context
This part belongs to the broader family of Microsemi's high-reliability Zener diodes. These components are engineered to provide stable voltage regulation in demanding industrial and aerospace sectors. The series is characterized by its glass passivation and rigorous manufacturing controls.
Replacement Considerations
Consult official Microsemi documentation for qualified substitute part numbers. Verify pinout compatibility and thermal performance before implementing any alternative components.
