1M150ZHR1G

Overview

The Taiwan Semiconductor Corporation 1M150ZHR1G is a single Zener diode with a nominal voltage of 150 V and a tolerance of 5%. It features a maximum power dissipation of 1 W and operates within a temperature range of -55°C to +150°C. The device utilizes a DO-41 (DO-204AL) axial through-hole package and holds AEC-Q101 automotive qualification. Key electrical characteristics include a maximum reverse leakage current of 5 µA, a Zener impedance of 1 kOhms, and a test current of 1.7 mA.

Feature Summary

• Automotive-grade reliability certified under the AEC-Q101 standard for robust performance in demanding environments.
• High thermal stability enabling continuous operation at junction temperatures up to 150°C.
• Low reverse leakage current ensuring minimal power loss and stable regulation in high-voltage applications.

Applications

• Voltage reference circuits requiring stable high-voltage regulation.
• Overvoltage protection stages in automotive electronic control units.
• Clamping applications in industrial power supply systems.

Procurement Notes

Verify the specific suffix 'R1' against official datasheets to confirm reel packaging specifications. Confirm AEC-Q101 compliance status directly with the manufacturer or authorized distributors. Ensure the DO-41 package dimensions match your PCB layout requirements before finalizing procurement decisions.

Selection Notes

Select this component when a 150 V Zener voltage is required with strict automotive reliability standards. The 1 W power rating supports moderate current handling in through-hole designs. Consider the 1 kOhm impedance for applications sensitive to dynamic voltage changes. Verify that the 5% tolerance meets the precision requirements of the target circuit design.

Part Context

This part belongs to the 1M150ZH series of high-power Zener diodes manufactured by Taiwan Semiconductor. The series is designed for general-purpose and specialized voltage regulation tasks. The 1M150ZHR1G variant specifically denotes the axial leaded configuration suitable for automated insertion processes.

Replacement Considerations

Consult official substitution guides for equivalent 150 V, 1 W Zener diodes with AEC-Q101 certification. Verify pinout compatibility and thermal resistance values before replacing the component in existing assemblies.
