Procurement Notes

Verify the specific ordering suffix 'C2G' against the manufacturer's official documentation to confirm halogen-free status and green compound specifications. Ensure that the procurement request explicitly references the correct packing code and quantity format to match the intended manufacturing assembly requirements.

Selection Notes

Select this component when a 1000V reverse voltage rating and 3A continuous forward current are required for PCB applications. Consider the 80A surge current capability for circuits experiencing transient load spikes. Verify that the operating environment remains within the specified -55°C to +150°C junction temperature range for optimal performance.

Part Context

This part belongs to the KBP301G through KBP307G series from Taiwan Semiconductor. The series shares identical mechanical dimensions and current ratings, differing primarily in their maximum repetitive peak reverse voltage ratings which range from 50V to 1000V. The KBP307G represents the highest voltage variant in this standard bridge rectifier lineup.

Replacement Considerations

Compatible substitutes include other manufacturers' KBP307 variants such as those from Microdiode or Nanjing International. Ensure replacement parts maintain the same 3A current rating, 1000V reverse voltage, and compatible physical footprint for direct PCB integration.
