Procurement Notes

Verify the specific ordering suffix 'C2' corresponds to the green compound packing code as documented in the official datasheet. Confirm that the 'G' suffix indicates halogen-free material compliance according to IEC 61249-2-21. Ensure the procurement specification matches the KBP157G electrical ratings, specifically the 1000 V reverse voltage and 1.5 A forward current capabilities required for the target design.

Selection Notes

Select this component when a 1000 V blocking voltage and 1.5 A continuous current are required in a through-hole KBP package. Consider the thermal resistance values and operating temperature range of -55°C to +150°C for high-temperature environments. Verify that the 50 A surge current rating meets the transient load requirements of the application circuit.

Part Context

This part belongs to the KBP151G through KBP157G series of glass passivated bridge rectifiers manufactured by Taiwan Semiconductor. The series offers various voltage ratings from 50 V to 1000 V while maintaining a consistent 1.5 A current rating and KBP case outline. The KBP157G represents the highest voltage variant in this specific lineup.

Replacement Considerations

Direct substitutes must match the 1000 V reverse voltage, 1.5 A forward current, and KBP-4 package dimensions. Verify compatibility regarding glass passivation technology and lead plating specifications to ensure equivalent performance in the existing circuit layout.
