Overview
The 1M180Z A0G is a single-channel Zener diode manufactured by Taiwan Semiconductor, designed for through-hole mounting in DO-41-2 packages. It features a nominal Zener voltage of 180 V with a tolerance of 5% and a power dissipation rating of 1 W. The device operates within a temperature range of -55°C to +150°C and includes AEC-Q101 qualification for automotive reliability. Key electrical characteristics include a maximum reverse leakage current of 5 uA, a Zener impedance of 1.2 kOhms, and a test current of 1.4 mA.
Feature Summary
- Provides stable voltage regulation via Zener breakdown mechanism
- Qualified for automotive applications under AEC-Q101 standards
- Engineered for high thermal stability across extended temperature ranges
Applications
- Voltage reference circuits in automotive electronics
- Overvoltage protection stages in industrial control systems
- Clamping applications in general-purpose power supplies
Procurement Notes
Verify component authenticity and lot traceability directly with the manufacturer or authorized distributors before procurement. Confirm that the specific ordering suffix matches the required package and tape-and-reel specifications. Ensure compliance with RoHS and REACH regulations as documented in the official datasheet. Request factory status verification to confirm current production availability and lifecycle stage.
Selection Notes
Select this component when a precise 180 V reference is required in axial leaded formats. The AEC-Q101 qualification makes it suitable for environments demanding higher reliability than standard commercial grades. Consider the 1.2 kOhm impedance value for noise-sensitive designs where lower dynamic resistance might be necessary.
Part Context
This part belongs to the 1M180ZH series of Zener diodes from Taiwan Semiconductor. The series offers various voltage options within the DO-41 package family. The 'A0G' suffix typically denotes specific packaging and environmental compliance attributes defined by the manufacturer for bulk distribution channels.
Replacement Considerations
Cross-reference with other 180 V Zener diodes in the DO-41 package having comparable 1 W power ratings and 5% tolerance. Verify pinout compatibility and thermal characteristics before substitution.
