Overview
The BYW29G-200-TR is a silicon rectifier diode manufactured by STMicroelectronics, designed for high-efficiency applications. It features a maximum average forward current of 8 A and a maximum repetitive peak reverse voltage of 200 V. The device exhibits a very low reverse recovery time of 35 ns and supports a non-repetitive peak forward surge current of 80 A. It is housed in a surface-mount D2PAK-3 package with a matte tin terminal finish. The component operates at a maximum junction temperature of 150 °C and complies with RoHS standards.
Feature Summary
- Designed for switchmode power supplies and high-frequency DC to DC converters
- Provides very low forward losses and negligible switching losses
- Capable of handling high surge currents and avalanche energy
Applications
- Switchmode power supply circuits
- High frequency DC to DC converters
- Low voltage high frequency inverters
- Free wheeling applications
- Polarity protection circuits
Procurement Notes
Verify the specific suffix -TR indicates tape and reel packaging configuration. Confirm the G suffix aligns with the required lead-free and RoHS compliance specifications. Ensure the D2PAK-3 package dimensions match the target PCB footprint requirements. Validate that the 200 V rating meets the circuit's peak inverse voltage demands. Check for any discontinued status updates from the manufacturer before finalizing procurement plans.
Selection Notes
Select this component when low forward voltage drop and fast recovery are critical for system efficiency. The 8 A current rating suits moderate power conversion tasks. The surface-mount D2PAK package facilitates automated assembly processes. Consider the thermal performance characteristics for heat dissipation needs in enclosed environments. Ensure the 200 V blocking voltage provides adequate margin for the application's operating conditions.
Part Context
This part belongs to the BYW29 series of high-efficiency fast recovery rectifier diodes produced by STMicroelectronics. The series is engineered for switchmode power applications requiring minimal conduction and switching losses. The BYW29G variant specifically denotes the lead-free construction within this product line. It serves as a discrete semiconductor solution for power management and conversion systems.
Replacement Considerations
Cross-reference with other BYW29 variants such as BYW29-200 or BYW29-400 for different voltage ratings. Verify pinout compatibility with existing TO-220AC or ISOWATT220AC designs if transitioning packages. Consult manufacturer datasheets for equivalent parts from other vendors like NXP or ON Semiconductor.
