1M180ZHR1G

Overview

The 1M180ZHR1G is a single Zener diode manufactured by Taiwan Semiconductor Corporation, designed for through-hole mounting in the DO-41 (DO-204AL) axial leaded package. It features a nominal Zener voltage of 180 V with a tight tolerance of 5%. The device supports a power dissipation of 1 W and operates within an extended junction temperature range from -55°C to +150°C. Key electrical characteristics include a maximum reverse leakage current of 5 µA and a Zener impedance of 1.2 kOhms at a test current of 1.4 mA. This component holds AEC-Q101 qualification, ensuring reliability for automotive applications.

Feature Summary

• Automotive-grade reliability certified under AEC-Q101 standards
• High thermal stability with operation up to 150°C junction temperature
• Precision voltage regulation with 5% tolerance on 180 V Zener voltage
• Robust axial leaded construction suitable for high-power dissipation

Applications

• Automotive electronic circuits requiring qualified voltage reference components
• Overvoltage protection stages in industrial power supplies
• Precision voltage regulation in high-temperature environments

Procurement Notes

Verify the specific suffix 'R1' against the official datasheet to confirm reel packaging specifications. Ensure the procurement channel provides the original manufacturer's documentation to validate the AEC-Q101 automotive qualification status. Cross-reference the DO-41 package dimensions with your PCB footprint requirements before finalizing orders.

Selection Notes

Select this component when a stable 180 V reference is required in automotive or harsh industrial environments. The DO-41 package offers higher power handling than surface-mount alternatives. Verify that the system's operating temperature remains within the specified -55°C to +150°C range to maintain the 5% voltage tolerance accuracy.

Part Context

This part belongs to the 1M180ZH series of Zener diodes from Taiwan Semiconductor. The series is characterized by its robust axial leaded design and compliance with automotive quality standards. It serves as a specialized voltage regulation solution distinct from standard general-purpose diodes, focusing on precision and thermal endurance.

Replacement Considerations

Direct substitutes must match the 180 V Zener voltage, 1 W power rating, DO-41 package, and AEC-Q101 qualification. Generic equivalents lacking automotive certification may not be suitable for validated automotive designs.
