Overview
The BYV29B-500,118 is a single ultrafast rectifier diode manufactured by WeEn Semiconductors. It features a maximum repetitive reverse voltage of 500 V and an average forward current rating of 9 A. The device exhibits a maximum forward voltage of 1.4 V and a typical reverse recovery time of 60 ns. It supports a forward surge current of 110 A and operates at junction temperatures up to 150°C. The component is housed in a D2PAK (SOT404) surface-mount package with two terminals and a tab.
Feature Summary
- Utilizes gold doping technology to achieve very soft recovery characteristics, which helps minimize electromagnetic interference.
Applications
- High-frequency switching power supplies
- Free-wheeling rectification in DC-DC converters
- General purpose rectification in electronic circuits
Procurement Notes
Verify the specific ordering code suffix, such as ,118, against official manufacturer documentation to confirm the tape and reel packaging configuration. Ensure that the D2PAK footprint requirements align with the target PCB design. Cross-reference the thermal resistance parameters from the datasheet for adequate heat dissipation planning in the final assembly.
Selection Notes
Select this component when a fast recovery time of approximately 60 ns is required alongside a 500 V blocking capability. The 9 A current rating suits moderate power applications where space constraints favor surface-mount mounting over through-hole options. Consider the soft recovery feature if EMI reduction is a critical design parameter compared to standard ultrafast alternatives.
Part Context
This part belongs to the BYV29B series of ultrafast rectifiers from WeEn Semiconductors. The series includes variants with different voltage ratings, such as the BYV29B-600. These devices are designed for high-efficiency applications requiring low reverse recovery charge and fast switching speeds, distinguishing them from standard recovery diodes in similar packages.
Replacement Considerations
Check for direct pin-compatible substitutes within the same voltage and current class. Verify that any alternative device maintains comparable reverse recovery time and forward voltage specifications to ensure circuit performance consistency without redesigning the thermal or layout constraints.
