Overview
The BYWF29-50-E3/45 is a fast recovery rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage of 50 V and an average forward rectified current of 8.0 A. The device utilizes glass passivation for environmental resistance and exhibits a typical fast recovery time of 25 ns. It is housed in the TO-263AB (D2PAK) surface-mount package, with physical dimensions of 10.26 mm length, 8.89 mm height, and 4.83 mm width.
Feature Summary
- Fast recovery performance with a typical 25 ns switching time
- Glass passivated junction for enhanced durability
- High surge current capability suitable for demanding applications
Applications
- High-frequency DC-DC converters
- Free-wheeling diodes in power supplies
- Polarity protection circuits
Procurement Notes
Verify the specific suffix E3/45 to confirm RoHS compliance and tube packaging format. Confirm the TO-263AB footprint matches the target PCB design. Check for recent Product Change Notifications regarding manufacturing site or material updates. Ensure the component meets the required thermal management specifications for the intended operating environment.
Selection Notes
Select this component when a low-voltage, high-current solution with rapid switching characteristics is required. The D2PAK package offers superior thermal dissipation compared to smaller surface-mount options. Consider the 50 V rating margin relative to the circuit's peak inverse voltage. Evaluate the 25 ns recovery time against the system's switching frequency requirements to minimize switching losses.
Part Context
This part belongs to the BYWF29 series of fast recovery rectifiers from Vishay. The series provides various voltage ratings while maintaining consistent current handling and package form factors. The E3 designation indicates lead-free construction compliant with international environmental standards. The 45 suffix typically denotes the standard tube packaging configuration used for automated assembly.
Replacement Considerations
Direct substitutes include other 50V 8A fast recovery diodes in the TO-263AB package. Verify that alternative components match the 25 ns recovery time and forward voltage characteristics. Ensure the replacement maintains the same pinout and thermal pad configuration for seamless integration.
