Overview
The onsemi 1N4755A-T50A is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 43 V with a tolerance of ±5%. The device dissipates up to 1 W of power and operates within a temperature range of -65 °C to +200 °C. Packaged in the DO-41 axial leaded format, it exhibits a maximum reverse leakage current of 5 µA at 32.7 V and a Zener impedance of 70 Ohms at a test current of 6 mA.
Feature Summary
- Provides stable voltage regulation using a single unidirectional Zener junction
- Constructed with hermetically sealed glass compression bonded technology
- Capable of operation across an extended industrial temperature range
Applications
- Voltage reference circuits requiring precise potential levels
- Overvoltage protection stages in electronic systems
- General purpose voltage regulation tasks
Procurement Notes
Verify the specific suffix T50A against official manufacturer documentation to confirm packaging configuration and availability status. Ensure compatibility with existing circuit designs regarding thermal dissipation requirements and lead form factors before finalizing procurement decisions.
Selection Notes
Select this component when a 43 V regulation point is required with standard 5% tolerance. Consider the DO-41 package dimensions and through-hole mounting style for board layout constraints. Evaluate the 1 W power rating against expected operating currents to ensure adequate thermal headroom.
Part Context
This part belongs to the standardized 1N47xx series of Zener diodes manufactured by onsemi. These components are widely utilized in discrete semiconductor applications where reliable voltage clamping or referencing is necessary. The series offers various voltage options within a consistent physical footprint.
Replacement Considerations
Cross-reference with other manufacturers offering equivalent 43 V, 1 W Zener diodes in the DO-41 package. Verify that alternative parts meet the same electrical specifications, particularly the 5% tolerance and thermal characteristics.
