Overview
The BAY73TR is a general-purpose rectifier diode manufactured by onsemi. It features an average rectified current of 500mA and a maximum DC reverse voltage of 125V. The device utilizes a DO-35 axial leaded package, suitable for through-hole mounting. Key electrical characteristics include a capacitance of 8pF measured at 0V and 1MHz. This component belongs to the single diodes product category within onsemi's discrete semiconductor lineup.
Feature Summary
- Provides reliable rectification with a 500mA average current rating
- Supports up to 125V DC reverse blocking voltage
- Utilizes standard DO-35 axial leaded package for board integration
Applications
- General-purpose signal rectification circuits
- Low-voltage power supply input stages
- Protection diodes in electronic assemblies
Procurement Notes
Verify component authenticity through authorized onsemi distributors or certified partners. Request official datasheets and material composition declarations to ensure compliance with RoHS standards. Confirm lot traceability and quality certifications prior to procurement to mitigate supply chain risks.
Selection Notes
Select this component for applications requiring moderate current handling and low reverse voltage tolerance. The DO-35 package offers compact axial integration. Evaluate thermal management requirements based on forward voltage drop and ambient operating conditions during circuit design.
Part Context
This part falls under onsemi's discrete diode portfolio, specifically single rectifier types. It serves as a foundational component for basic power conversion and signal processing tasks. The manufacturer provides comprehensive technical documentation supporting design-in processes for industrial and consumer electronics.
Replacement Considerations
Public sources indicate the BAY73TR has reached an obsolete lifecycle status. Designers should identify active substitute parts from onsemi or other manufacturers that match the 500mA current and 125V voltage specifications while maintaining compatible package dimensions.
