Overview
The 1M150ZH is a Zener diode manufactured by Taiwan Semiconductor, designed for through-hole mounting in the DO-41-2 package. It features a nominal Zener voltage of 150 V with a 5% tolerance 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 µA and a Zener impedance of 1 kΩ at a test current of 1.7 mA.
Feature Summary
- Automotive-grade reliability certified under AEC-Q101 standards
- High thermal stability supporting operation up to +150°C
- Low leakage current for efficient voltage regulation
Applications
- Automotive electronic circuits requiring robust voltage reference
- Industrial control systems utilizing through-hole components
- Power supply protection and regulation modules
Procurement Notes
Verify the specific suffix 'ZH' against official datasheets to confirm AEC-Q101 qualification status, as packaging variations may exist. Ensure the DO-41-2 footprint matches the target PCB design. Confirm RoHS compliance details directly from the manufacturer's documentation prior to integration into regulated assemblies.
Selection Notes
Select this component when high-temperature performance and automotive certification are required. The 150 V rating suits applications needing precise regulation above standard low-voltage options. Consider the 1 kΩ impedance for noise-sensitive designs where higher impedance may impact dynamic response.
Part Context
This part belongs to the 1M series of axial leaded Zener diodes from Taiwan Semiconductor. The series offers various voltage ratings in the DO-41 package, providing a standardized solution for general-purpose and specialized voltage regulation tasks across consumer and industrial electronics sectors.
Replacement Considerations
Check for direct equivalents such as 1N5384B or 1N5939B if AEC-Q101 qualification is not strictly mandatory. Verify pinout compatibility and ensure replacement parts meet the 150 V and 1 W specifications.
