Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm packaging type and halogen-free status. Ensure the procurement channel provides valid traceability for RoHS compliance. Cross-reference the part number with official datasheets to confirm electrical ratings match application requirements before finalizing orders.

Selection Notes

Select this component when a 6 A current rating and 200 V blocking voltage are required in a through-hole KBU-4 package. Consider the 175 A surge current capability for applications with high inrush currents. Verify thermal management needs given the 150°C maximum junction temperature limit and the specific forward voltage drop characteristics.

Part Context

This part belongs to the KBU series of glass passivated bridge rectifiers from Taiwan Semiconductor. The series offers various voltage ratings while maintaining consistent mechanical dimensions and current handling capabilities. The 'G' suffix typically indicates halogen-free material composition within the manufacturer's product line.

Replacement Considerations

Direct replacements must match the 6 A current rating, 200 V reverse voltage, and KBU-4 package footprint. Verify that alternative components meet the same surge current and thermal specifications. Check for equivalent glass passivation technology to ensure similar reliability profiles.
