Overview
The BYT30PI-400RG is a fast recovery rectifier diode manufactured by STMicroelectronics. It features an average forward current of 30 A at a case temperature of 60°C and a repetitive peak reverse voltage of 400 V. The device operates within a junction temperature range of -40 to +150 °C with a power dissipation capacity of 50 W. Key electrical parameters include a maximum forward voltage of 1.5 V, a typical reverse recovery time of 50 ns, and a surge non-repetitive forward current rating of 350 A.
Feature Summary
- Very low reverse recovery time for reduced switching losses
- Low noise turn-off switching characteristics
- Electrically insulated construction with 2500 VRMS isolation voltage
Applications
- Free wheeling diode in converters
- Motor control circuits
- Rectifier in switch mode power supplies
Procurement Notes
Verify the component status as the source datasheet indicates an August 1998 edition. Confirm that the specific suffix 'RG' aligns with the manufacturer's current packaging and compliance specifications, as older documentation may not reflect recent manufacturing changes or RoHS directives. Ensure the DOP3I package dimensions match your PCB layout requirements before finalizing procurement.
Selection Notes
Select this component for applications requiring high-speed rectification with minimal switching noise. The 400 V rating suits medium-voltage AC-DC conversion systems. Consider the thermal resistance of 1.8 °C/W when designing heat sinking solutions. The insulated package allows for direct mounting to heatsinks without additional insulating washers, simplifying assembly in high-voltage environments.
Part Context
This part belongs to the BYT30P series of fast recovery rectifiers from STMicroelectronics. The series is designed for general-purpose high-frequency applications where low reverse recovery charge is critical. The DOP3I plastic package provides mechanical robustness and thermal efficiency for through-hole mounting in industrial and consumer electronics.
Replacement Considerations
