Overview
The 1N4761A B0G is a Zener diode manufactured by Taiwan Semiconductor Corporation. It features a nominal Zener voltage of 75 V with a tolerance of 5%. The device is designed for through-hole mounting in a DO-41-2 (DO-204AL) axial package. It supports a 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 uA, a Zener impedance of 175 Ohms, and a test current of 3.3 mA. The component is AEC-Q101 qualified.
Feature Summary
- Provides stable voltage regulation at a nominal 75 V level with tight manufacturing tolerances.
- Engineered for high-temperature reliability with an extended operating range up to 150°C.
- Includes built-in strain relief to enhance mechanical durability during soldering and operation.
Applications
- Voltage reference circuits requiring precise potential levels
- Overvoltage protection stages in industrial electronics
- Power supply output regulation systems
Procurement Notes
Verify the specific suffix B0G against official datasheets to confirm packaging details and compliance status. Confirm AEC-Q101 qualification requirements if automotive standards are mandatory. Ensure the DO-41-2 footprint matches the target PCB design constraints before finalizing procurement orders.
Selection Notes
Select this component when a robust 75 V regulation point is needed in a standard axial package. The AEC-Q101 qualification makes it suitable for environments demanding higher reliability than standard commercial grades. Consider the 175 Ohm impedance for applications sensitive to dynamic voltage changes under varying load currents.
Part Context
This part belongs to the 1N4761AH series of 1 W Zener diodes from Taiwan Semiconductor. The series covers a wide voltage range, with the 1N4761 variant specifically targeting the 75 V segment. These components are widely used in general-purpose discrete semiconductor applications requiring reliable voltage clamping or referencing.
Replacement Considerations
Cross-reference with other manufacturers' 1N4761A equivalents such as those from Microchip or Vishay. Verify that substitute parts maintain the same DO-41 package dimensions and 75 V nominal voltage to ensure direct compatibility without circuit redesign.
