1EZ130D10/TR8

Overview

The Microsemi Corporation 1EZ130D10/TR8 is a silicon unidirectional Zener diode rated at 130V nominal voltage with a ±10% tolerance. It features a maximum power dissipation of 1W and operates within a temperature range of -65°C to +150°C. The device utilizes a DO-204AL (DO-41) axial leaded plastic package, measuring 5.21 x 2.72mm. Key electrical characteristics include a reverse leakage current of 500nA at 98.8V and a forward voltage drop of 1.2V. This component is classified as obsolete.

Feature Summary

• Provides stable voltage regulation in the 130V range for circuit protection applications
• Engineered for high-temperature operation up to 150°C using robust silicon construction
• Utilizes an axial leaded plastic package designed for through-hole mounting

Applications

• Voltage reference circuits requiring 130V stability
• Overvoltage protection stages in industrial electronics
• Clamping applications in high-temperature environments

Procurement Notes

This component is officially marked as obsolete by the manufacturer. Procurement requires verification of availability from authorized distributors or surplus suppliers. Buyers must confirm the specific lot date code and physical condition before acquisition. Ensure that the DO-204AL package dimensions match the target PCB footprint. Regulatory compliance status should be verified against current environmental standards due to the product's end-of-life status.

Selection Notes

Select this part only if a 130V Zener voltage with 10% tolerance meets the design requirements. Verify that the 1W power rating is sufficient for the expected thermal load. The DO-204AL package dictates the board layout constraints. Consider the operating temperature range limits when designing for extreme environments. Since the part is obsolete, evaluate alternative sources carefully to ensure authenticity and performance consistency.

Part Context

The 1EZ series represents a line of 1-watt Zener diodes manufactured by Microsemi Corporation. These components are designed for general-purpose voltage regulation and clamping tasks. The 1EZ130D10 variant specifically targets the 130V segment of this lineup. The TR8 suffix indicates tape and reel packaging for automated assembly processes. This series is characterized by its plastic encapsulation and axial lead configuration.
