1M180ZH

Overview

The 1M180ZH is a single-channel Zener diode manufactured by Taiwan Semiconductor, designed for through-hole mounting in the DO-41 (DO-204AL) package. 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 holds AEC-Q101 qualification. Key electrical parameters include a maximum reverse leakage current of 5 µA, a Zener impedance of 1.2 kOhms at a test current of 1.4 mA, and a unit weight of 310 mg.

Feature Summary

• AEC-Q101 qualified for automotive reliability standards
• High thermal stability with extended operating temperature range up to 150°C
• Low leakage current characteristics for efficient regulation
• Robust axial leaded construction for reliable through-hole integration

Applications

• Automotive electronic circuit protection
• Voltage reference applications in regulated power supplies
• Overvoltage protection circuits in industrial systems

Procurement Notes

Verify component authenticity against official Taiwan Semiconductor documentation before integration. Confirm that the specific ordering suffix matches the required reel packaging configuration. Ensure compliance with RoHS and REACH SVHC directives as specified in the manufacturer's datasheet. Cross-reference the part number with authorized distributors to validate supply chain integrity and traceability records.

Selection Notes

Select this component when a stable 180 V reference is required in high-temperature environments. The DO-41 package suits designs needing robust mechanical anchoring. Verify that the 1 W power rating aligns with the expected thermal load. Consider the 1.2 kOhm impedance if precise dynamic response is critical for the target application circuitry.

Part Context

This part belongs to the 1M180ZH series of Zener diodes from Taiwan Semiconductor. It shares the DO-41 form factor with other variants in the family but is distinguished by its specific 180 V breakdown voltage. The series is engineered for general-purpose regulation and protection tasks requiring standardized axial leaded components.

Replacement Considerations

Consult official substitution guides for equivalent parts with matching 180 V Zener voltage, 1 W power rating, and DO-41 package dimensions. Verify that any alternative maintains AEC-Q101 qualification and similar leakage specifications.
