The BY253G is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation. It features a maximum average forward rectified current of 3A and a repetitive peak reverse voltage of 600V. The device utilizes standard technology and is housed in the DO-201AD axial leaded package. Key electrical characteristics include a maximum DC reverse leakage current of 5 µA at 600V and a junction temperature range from -55°C to 150°C.
Verify the manufacturer marking on the component body matches 'BY253G' to ensure authenticity. Confirm the package type is DO-201AD and check for physical damage to leads. Request the specific datasheet from Taiwan Semiconductor to validate electrical parameters against your design requirements before finalizing procurement.
Select this component when a 3A current rating and 600V blocking capability are required for through-hole mounting. Ensure the application environment stays within the specified -55°C to 150°C junction temperature range. Consider the DO-201AD package dimensions for PCB layout compatibility and verify that standard recovery characteristics meet the circuit speed requirements.
This diode belongs to the family of general-purpose rectifiers designed for reliable performance in various electronic assemblies. It serves as a fundamental component for converting alternating current to direct current in power management circuits. The axial lead configuration facilitates easy integration into traditional printed circuit board designs and wire-wrapped applications.
Compatible substitutes include BY253GP-E3/73 and BY253GPHE3/54, which share similar electrical specifications and package types. Verify pinout compatibility and thermal characteristics when swapping between these variants to ensure circuit integrity.
