1M180Z

Overview

The 1M180Z is a single Zener diode manufactured by Taiwan Semiconductor, designed for through-hole mounting in the DO-41-2 axial leaded package. It features a nominal Zener voltage of 150 V with a tight tolerance of 5%. The device supports a maximum power dissipation of 1 W and operates within an extended 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 kOhms at a test current of 1.7 mA.

Feature Summary

• Provides stable voltage regulation with a 150 V nominal breakdown point
• Engineered for high thermal stability across wide operating temperatures
• Constructed in a robust axial leaded package for reliable through-hole integration

Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in electronic systems
• Clamping applications in power supply designs

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number with official datasheets. Confirm RoHS compliance status and specific packaging options such as reel or cut tape availability directly with authorized distributors. Ensure the selected variant matches the required axial lead configuration and thermal specifications for the intended application environment.

Selection Notes

Select this component when a 150 V regulation point is required in a through-hole design. The 1 W power rating suits moderate current applications, while the 5% tolerance ensures consistent performance. Consider the DO-41 package dimensions for PCB layout constraints and verify that the operating temperature range aligns with the system's environmental conditions.

Part Context

This component belongs to the 1MxxxZ series of Zener diodes from Taiwan Semiconductor. The series offers various voltage ratings within the same DO-41 package form factor, allowing designers to standardize on a single footprint while adjusting voltage requirements. The 'Z' suffix typically denotes the specific tolerance class associated with this product line.

Replacement Considerations

Compatible substitutes include other 150 V Zener diodes in the DO-41 package with comparable 1 W power ratings and 5% tolerance. Verify pinout compatibility and thermal characteristics before substitution.
