KBP203

Overview

The GeneSiC Semiconductor KBP203 is a silicon bridge rectifier designed for through-hole mounting in the KBP package. It supports a repetitive peak reverse voltage (VRRM) of 60 V and a continuous forward current (IF) of 2 A. The device features a maximum non-repetitive surge forward current of 280 A under half-sine wave conditions. Electrical characteristics include a diode forward voltage of 1.1 V at 2 A and a reverse current of 10 µA at 50 V. Thermal resistance from junction to case is rated at 25.0 °C/W, with an operating temperature range spanning -50 °C to +150 °C.

Feature Summary

• Built-in printed circuit board stand-offs facilitate reliable mounting on PCBs.
• High temperature soldering capability guaranteed up to 265°C for 10 seconds.
• Plastic package meets Underwriters Laboratory Flammability Classification 94V-0.

Applications

• General purpose rectification in power supply circuits
• AC to DC conversion modules
• Low voltage bridge rectifier applications

Procurement Notes

Verify the specific voltage rating against application requirements, as the KBP203 is rated for 60 V VRRM within the KBP201-KBP204 series. Confirm package compatibility with the KBP footprint and ensure thermal management aligns with the 25.0 °C/W junction-to-case resistance. Check RoHS compliance status via manufacturer documentation before integration.

Selection Notes

Select the KBP203 when a 60 V reverse voltage rating and 2 A continuous current are required. Compare against KBP201 (50 V) and KBP202 (100 V) for appropriate voltage headroom. Ensure the PCB layout accommodates the KBP package dimensions and built-in stand-offs for mechanical stability during operation.

Part Context

The KBP203 belongs to the KBP201 through KBP204 series of silicon bridge rectifiers manufactured by GeneSiC Semiconductor. This family offers standardized ratings for low-voltage AC rectification, differentiated primarily by their repetitive peak reverse voltage capabilities ranging from 50 V to 400 V across the series.

Replacement Considerations

Direct substitutes include other KBP-series bridge rectifiers with matching 60 V ratings, such as generic equivalents from manufacturers like Vishay or Littelfuse. Verify that replacement parts maintain the same 2 A current rating, KBP package outline, and thermal characteristics to ensure pinout and performance compatibility.
