1M150Z

Overview

The 1M150Z is a single Zener diode manufactured by Taiwan Semiconductor Corporation, designed for through-hole mounting in the DO-41-2 (DO-204AL) axial package. It features a nominal Zener voltage of 150 V with a tolerance of 5% and a maximum power dissipation of 1 W at ambient conditions. The device operates within a temperature range of -55°C to +150°C junction temperature. Key electrical characteristics include a maximum reverse leakage current of 5 µA and a Zener impedance of 1 kOhms measured at a test current of 1.7 mA.

Feature Summary

• Provides stable voltage regulation via Zener breakdown mechanism in the reverse bias region
• Engineered for high thermal stability across an extended operating temperature range up to 150°C
• Constructed in a robust axial leaded package suitable for reliable through-hole circuit integration

Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages for sensitive electronic components
• Clamping applications in power supply output stages

Procurement Notes

Verify component authenticity against official Taiwan Semiconductor datasheets before integration. Confirm that the specific order matches the 1M150Z designation to ensure correct 150 V rating and DO-41 packaging. Request RoHS compliance documentation and material declarations as required by project specifications. Validate supplier authorization status to mitigate counterfeit risks.

Selection Notes

Select this component when a 150 V regulation point is required in through-hole designs. Ensure the circuit can handle the 1 W power dissipation limit without exceeding thermal constraints. Verify that the 5% voltage tolerance aligns with system accuracy requirements. Consider the 1 kOhm impedance value for dynamic load regulation performance needs.

Part Context

This part belongs to the 1MxxxZ series of Zener diodes from Taiwan Semiconductor. The series offers various voltage ratings within the same DO-41 form factor, allowing designers to standardize on a single package type while adjusting voltage parameters. This specific model represents the 150 V variant within that standardized lineup.

Replacement Considerations

Cross-reference with other manufacturers offering 150 V, 1 W Zener diodes in DO-41 packages. Verify pinout compatibility and thermal resistance values. Ensure equivalent Zener impedance and leakage current specifications are met for direct substitution.
