1N4759AHB0G

Overview

The 1N4759AHB0G is a 62V Zener diode manufactured by Taiwan Semiconductor Corporation. It features a 1W power dissipation rating and a 5% voltage tolerance. The device utilizes a DO-204AL (DO-41) through-hole package with a glass passivated junction. Key electrical specifications include a maximum reverse leakage current of 5µA and a Zener impedance of 2000 Ohms at the test current of 7mA. It operates within a temperature range of -55°C to +150°C and holds AEC-Q101 qualification.

Feature Summary

• Glass passivated junction construction for enhanced stability
• AEC-Q101 qualified for automotive reliability standards
• Metallurgically bonded double slug type design
• High temperature soldering capability

Applications

• Automotive voltage regulation circuits
• Industrial power supply protection
• General purpose voltage reference applications

Procurement Notes

Verify component authenticity and datasheet alignment before procurement. Confirm AEC-Q101 status and RoHS compliance via official manufacturer documentation. Ensure packaging matches specified requirements, as variations exist between standard and bulk formats. Cross-reference part numbers carefully to avoid substitution errors in critical designs.

Selection Notes

Select this component for applications requiring robust automotive-grade Zener regulation. The DO-41 package suits through-hole mounting constraints. Consider the 2000 Ohm impedance for high-impedance reference needs. Verify thermal management capabilities align with the 150°C maximum junction temperature limit in dense PCB layouts.

Part Context

This part belongs to the 1N47xx series of one-watt Zener diodes produced by Taiwan Semiconductor. The 'HB' suffix typically denotes specific packaging or tape-and-reel configurations within their product line. It serves as a standardized replacement for legacy 1N4759A devices in modern electronic assemblies requiring verified quality standards.

Replacement Considerations

Direct substitutes include the 1N4759A from other manufacturers such as Central Semiconductor or Multicomp, provided they meet the same 62V, 1W, and DO-41 specifications. Verify pinout compatibility and thermal characteristics when swapping brands.
