2KBP10M

Overview

The 2KBP10M is a single-phase glass passivated bridge rectifier manufactured by Fairchild Semiconductor, now part of onsemi. It provides a maximum repetitive reverse voltage of 1000 V and an average rectified forward current of 2.0 A at 50°C ambient temperature. The device features a non-repetitive peak forward surge current rating of 60 A for an 8.3 ms half-sine wave. Electrical characteristics include a typical forward voltage of 1.1 V per element at 3.14 A and a total capacitance of 25 pF per leg. Thermal resistance from junction to ambient is 18 °C/W per leg.

Feature Summary

• Glass passivation ensures reliable low-cost construction utilizing molded plastic technique.
• Surge overload capability rated at 60 amperes peak.
• UL certified under file number E111753.

Applications

• General purpose AC-to-DC full-wave bridge rectification in switching power supplies.
• Adapters and chargers requiring high reliability.
• Home appliances with standard recovery requirements.

Procurement Notes

Verify the manufacturer origin, as the datasheet identifies Fairchild Semiconductor while the brand is listed as onsemi due to acquisition. Confirm the package style matches the KBPM form factor. Ensure the specific suffix corresponds to the 1000V rating variant within the series. Request traceability documentation to mitigate counterfeit risks associated with this component type.

Selection Notes

Select the 2KBP10M when a 1000 V peak reverse voltage is required alongside a 2.0 A continuous forward current capacity. This component is suitable for applications needing a 60 A surge current rating. Consider thermal management if operating near the 50°C limit, as derating curves apply. Verify that the 1.1 V forward voltage drop aligns with system efficiency targets.

Part Context

This component belongs to the 2KBP series of bridge rectifiers, which includes variants ranging from 50 V to 1000 V reverse voltage. The series shares common physical dimensions and electrical characteristics such as surge current and packaging style. The 2KBP10M specifically denotes the 1000 V rating within this family of glass-passivated silicon bridge rectifiers.

Replacement Considerations

Compatible substitutes include other 2A, 1000V bridge rectifiers in the KBPM package. Equivalent part numbers may include 3N259 or generic equivalents meeting the same electrical specifications. Verify pinout compatibility and thermal resistance values before substitution.
