1EZ130D/TR12

Overview

The Microsemi Corporation 1EZ130D/TR12 is a single Zener diode with a nominal voltage of 130 V and a maximum power dissipation of 1 W. It features a tolerance of ±20% and utilizes the DO-204AL (DO-41) axial through-hole package. The component operates within a temperature range of -65°C to +175°C. It is supplied in tape and reel packaging.

Feature Summary

• Provides stable voltage regulation for circuit protection applications
• Designed for robust performance in high-temperature environments
• Utilizes an axial-leaded package suitable for through-hole mounting

Applications

• Voltage reference circuits
• Overvoltage protection
• Clamping applications

Procurement Notes

Verify current availability status as this component may be obsolete or discontinued. Confirm RoHS compliance requirements, as specific suffixes indicate environmental standards. Ensure the ordering suffix matches the required packaging format. Cross-reference datasheets for exact electrical parameters before integration.

Selection Notes

Select this component when a 130 V Zener voltage is required with 1 W power handling capability. Consider the ±20% tolerance for non-critical regulation tasks. The DO-41 package is appropriate for standard through-hole PCB layouts. Verify thermal management needs for continuous operation at elevated temperatures.

Part Context

This part belongs to the 1EZ series of Zener diodes manufactured by Microsemi Corporation, now part of Microchip Technology. The series offers various voltage ratings and power dissipation levels. The TR12 suffix indicates tape and reel packaging for automated assembly processes.

Replacement Considerations

Check for direct substitutes from Microchip or other manufacturers offering identical 130 V, 1 W specifications in DO-41 packages. Verify pinout compatibility and thermal characteristics. Ensure replacement parts meet the same voltage tolerance and temperature range requirements.
