1M110Z

Overview

The Taiwan Semiconductor Corporation 1M110Z is a through-hole Zener diode housed in the DO-41 (DO-204AL) axial leaded package. It provides a nominal Zener voltage of 110 V with a tolerance of 5%. The device is rated for a maximum power dissipation of 1 W at ambient temperatures up to +150 °C, with an extended operating range from -55 °C to +150 °C. Key electrical characteristics include a maximum reverse leakage current of 5 µA and a Zener impedance of 550 Ω. Testing is specified at a current of 2 mA.

Feature Summary

• Provides stable voltage regulation via avalanche breakdown mechanism
• Designed for high thermal stability across wide temperature ranges
• Constructed with robust axial leads for reliable through-hole mounting

Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in power supply inputs
• Clamping applications in signal conditioning paths

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact packaging configuration and compliance status. Ensure the requested variant matches the required mechanical dimensions and terminal finish specifications for your assembly process. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when a 110 V regulation point is required within a 1 W power budget. Confirm that the circuit design accommodates the specified 550 Ω dynamic impedance for noise-sensitive applications. Verify that the PCB layout supports the DO-41 footprint and allows adequate spacing for the axial lead configuration during insertion and soldering operations.

Part Context

This component belongs to the 1M series of general-purpose Zener diodes manufactured by Taiwan Semiconductor. The series offers various voltage ratings within the same standardized DO-41 package form factor. This specific model represents the 110 V option within that lineup, sharing common thermal and mechanical characteristics with other voltages in the family.

Replacement Considerations

Direct replacements must match the 110 V nominal voltage, 1 W power rating, and DO-41 package type. Verify equivalent Zener impedance and leakage current specifications to ensure circuit performance parity. Consult manufacturer substitution guides for cross-brand equivalents with identical pinout and thermal derating curves.
