1M160ZHB0G

Overview

The 1M160ZHB0G is a single Zener diode manufactured by Taiwan Semiconductor Corporation, designed for through-hole mounting in DO-41-2 packages. It features a nominal Zener voltage of 160 V with a tolerance of 5%. The device supports a power dissipation of 1 W and operates within a temperature range of -55 °C to +150 °C. Key electrical parameters include a maximum reverse leakage current of 5 µA and a Zener 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
• High-temperature soldering capability up to 260 °C for 10 seconds

Applications

• Voltage regulation circuits requiring stable high-voltage references
• Protection against overvoltage transients in industrial equipment
• Clamping applications in general-purpose electronic systems

Procurement Notes

Verify the specific suffix HB0G against official datasheets to confirm packaging or compliance variations. Confirm RoHS and REACH SVHC status directly with the manufacturer. Check lead availability and production cycles as stock levels fluctuate. Ensure the DO-41 package dimensions match your PCB layout requirements before ordering.

Selection Notes

Select this component when a 160 V breakdown voltage is required in a standard through-hole configuration. The 1 W power rating suits moderate current applications. Verify that the 1.1 kΩ impedance meets your circuit's noise and stability needs. Consider the operating temperature range if deployed in extreme environments.

Part Context

This part belongs to the 1MxxxZ series of 1 Watt Zener Voltage Regulators from Taiwan Semiconductor. These devices are characterized by their robust glass passivation and reliable performance in demanding conditions. The series offers various voltage options within the DO-41 package format.

Replacement Considerations

Equivalent parts must match the 160 V Zener voltage, 1 W power rating, and DO-41 package. Verify compatibility with other manufacturers' 1N47xx series equivalents, ensuring identical electrical characteristics and thermal limits.
