1M180Z R1G

Overview

The 1M180Z R1G 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 maximum power dissipation of 1 W and operates within a junction temperature range of -55°C to +150°C. Key electrical characteristics include a maximum reverse leakage current of 5 µA at the rated voltage and a Zener impedance of 1.2 kΩ measured at a test current of 1.4 mA. This component is qualified under the AEC-Q101 standard for automotive applications.

Feature Summary

• Provides stable voltage regulation with a nominal 180 V breakdown point and ±5% tolerance.
• Qualified for automotive electronics environments under the AEC-Q101 reliability standard.
• Engineered for high thermal stability with an extended operating junction temperature range up to 150°C.
• Utilizes a robust DO-41 axial leaded package suitable for reliable through-hole circuit board integration.

Applications

• Automotive electronic circuits requiring AEC-Q101 compliant voltage reference components.
• General-purpose voltage regulation and protection stages in industrial control systems.
• Overvoltage protection interfaces for sensitive semiconductor devices in power supply units.

Procurement Notes

Verify the specific suffix 'R1G' against official manufacturer documentation to confirm reel packaging specifications and ensure alignment with intended automated assembly processes. Confirm that the AEC-Q101 qualification status remains active for this specific part number variant before finalizing procurement contracts. Cross-reference the DO-41 package dimensions with PCB footprint requirements to guarantee mechanical compatibility during production assembly.

Selection Notes

Select this component when a precise 180 V regulation point is required in through-hole designs. The ±5% tolerance ensures consistent performance across varying manufacturing batches. Consider the 1 W power rating and 1.2 kΩ impedance for thermal management calculations in high-reliability applications. The AEC-Q101 qualification makes it suitable for automotive environments where strict reliability standards are mandatory.

Part Context

This part belongs to the 1M180ZH series of Zener diodes from Taiwan Semiconductor. The series offers various voltage ratings within the same DO-41 package family, allowing designers to maintain consistent mechanical footprints while adjusting electrical parameters. The inclusion of the R1G suffix typically denotes specific tape-and-reel packaging configurations for automated handling.

Replacement Considerations

Consult official cross-reference lists for direct substitutes. Verify that any alternative component matches the 180 V Zener voltage, 1 W power dissipation, DO-41 package, and AEC-Q101 qualification if automotive use is required.
