1M110ZH

Overview

The 1M110ZH is a Zener diode manufactured by Taiwan Semiconductor, designed for voltage regulation applications. It features a nominal Zener voltage of 110 V with a tolerance of 5%. The device supports a maximum power dissipation of 1000 mW and operates within a temperature range from -55 °C to +175 °C. Key electrical characteristics include a maximum reverse leakage current of 5 uA and a Zener impedance of 250 ohms at a test current of 4.5 mA. This component is AEC-Q101 qualified for automotive reliability and is available in the DO-15 axial package.

Feature Summary

• AEC-Q101 qualified for automotive-grade reliability standards
• High operating junction temperature capability up to 175 °C
• Guardring design provides enhanced overvoltage protection stability

Applications

• Automotive electronic circuit voltage regulation
• General-purpose power supply reference voltage generation
• Overvoltage protection circuits requiring high thermal stability

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm packaging type and compliance status. Ensure that the selected variant matches the required AEC-Q101 qualification if used in automotive contexts. Cross-reference the part number with authorized distributors to confirm current availability and lead times before finalizing procurement plans.

Selection Notes

Select this component when a stable 110 V reference is required in high-temperature environments. The 1000 mW power rating suits moderate current regulation tasks. Verify that the 250 ohm impedance meets the noise sensitivity requirements of the target application. Consider the DO-15 package dimensions for PCB layout constraints.

Part Context

This part belongs to the 1MxxxZ series of Zener diodes from Taiwan Semiconductor. The series is characterized by robust construction suitable for demanding industrial and automotive conditions. The 'H' suffix typically denotes specific packaging or compliance attributes as defined by the manufacturer.

Replacement Considerations

Direct replacements must match the 110 V Zener voltage, 1 W power rating, and DO-15 package. Verify equivalent AEC-Q101 qualification and thermal performance characteristics before substitution.
