1N4754AHB0G

Overview

The 1N4754AHB0G is a glass passivated junction silicon Zener diode manufactured by Taiwan Semiconductor. It provides a nominal Zener voltage of 39 V with a tolerance of 5%. The device features a power dissipation rating of 1 W and operates within a temperature range of -65°C to +200°C. Key electrical characteristics include a maximum reverse leakage current of 5 uA and a Zener impedance of 60 Ohms at a test current of 6.5 mA. It utilizes the DO-41-2 through-hole package, measuring 5.2 mm in length, 2.7 mm in width, and 2.7 mm in height.

Feature Summary

• Glass passivated junction construction for enhanced stability
• Built-in strain relief design for mechanical durability
• High temperature soldering capability up to 260°C

Applications

• Voltage regulation circuits
• Clipping and clamping applications
• Reference voltage sources

Procurement Notes

Verify the specific suffix HB0G against official datasheets to confirm RoHS compliance and packaging details. Confirm lead finish specifications and ensure the DO-41-2 package dimensions match board layout requirements. Cross-reference thermal resistance values for proper heat dissipation planning in high-density assemblies.

Selection Notes

Select this component when a precise 39 V reference is required in through-hole designs. Consider the 5% tolerance and 60 Ohm impedance for accuracy needs. Evaluate the 1 W power rating against circuit load conditions. Ensure operating temperatures remain within the specified -65°C to +200°C range for reliable performance.

Part Context

This part belongs to the 1N47xxA series of 1 Watt Zener diodes from Taiwan Semiconductor. These components are designed for general-purpose voltage regulation and protection. The series offers various voltage options within the same DO-41 package form factor, allowing for standardized inventory management across different voltage requirements.

Replacement Considerations

Check for equivalents such as 1N4754A or 1N4754-G from other manufacturers. Verify that substitute parts maintain the 39 V Zener voltage, 1 W power rating, and DO-41 package compatibility. Ensure thermal and electrical characteristics align with original design specifications.
