1M160Z

Overview

The 1M160Z is a single silicon Zener diode manufactured by Taiwan Semiconductor, designed for through-hole mounting in the DO-41 (DO-204AL) package. It features a nominal Zener voltage of 160 V with a tolerance of ±5%. The device supports a maximum power dissipation of 1 W and operates within a temperature range of -55 °C to +150 °C. Key electrical characteristics include a maximum reverse leakage current of 5 µA and a dynamic impedance of 1.1 kΩ at a test current of 1.6 mA.

Feature Summary

• Hermetically sealed glass construction with compression bonded design
• Corrosion-resistant external surfaces and solderable tin-plated terminals
• Lead-free and RoHS compliant manufacturing

Applications

• Voltage regulation circuits requiring stable reference levels
• Overvoltage protection for sensitive electronic components
• Clamping applications in high-voltage signal paths

Procurement Notes

Verify component authenticity against official Taiwan Semiconductor datasheets before integration. Confirm that the DO-41 package dimensions and lead specifications match your PCB footprint requirements. Ensure thermal management strategies account for the 1 W power dissipation limit under worst-case operating conditions to maintain reliability within the specified temperature range.

Selection Notes

Select this component when a precise 160 V breakdown voltage is required in a standard axial leaded format. The DO-41 package offers robust mechanical stability for through-hole assembly processes. Consider the 1.1 kΩ dynamic impedance when designing for low-noise applications, as higher impedance may impact regulation accuracy in specific circuit topologies compared to lower impedance alternatives.

Part Context

This part belongs to the 1MxxxZ series of 1 Watt Zener voltage regulators from Taiwan Semiconductor. The series utilizes JEDEC-standardized DO-41 packaging, ensuring compatibility with existing through-hole manufacturing infrastructure. These devices are engineered for general-purpose voltage regulation tasks where moderate power handling and reliable performance across wide temperature ranges are essential.

Replacement Considerations

Equivalent parts must match the 160 V Zener voltage, 1 W power rating, and DO-41 package form factor. Verify that substitute components meet the same 5% tolerance and leakage current specifications to ensure circuit performance parity.
