Procurement Notes

Verify the specific suffix against the manufacturer's official datasheet to confirm pinout and thermal specifications. Ensure the component matches the required voltage and current ratings for the target circuit design. Cross-reference the manufacturing date code and RoHS compliance status with the supplier's documentation prior to finalizing procurement orders.

Selection Notes

Select this component for applications requiring fast switching speeds and high reliability in medium-power circuits. The ITO-220AC package provides robust mechanical stability and efficient heat dissipation capabilities. Consider the 300 V reverse voltage rating when designing for AC line voltages or lower DC bus applications where fast recovery is critical.

Part Context

This part belongs to the BYV29F series of fast recovery rectifiers from Vishay. The series is characterized by its use of glass passivation technology to protect the silicon junction. These devices are designed to replace slower standard recovery diodes in modern high-efficiency power supplies and motor control systems.

Replacement Considerations

Check for direct substitutes such as the BYV29F-400-E3/45 if a higher voltage rating is acceptable. Verify compatibility with other fast recovery diodes in the same package family, ensuring that reverse voltage and forward current ratings meet or exceed the original design requirements.
