KBP201G

Overview

The KBP201G is a single-phase bridge rectifier manufactured by SMC Diode Solutions. It features a glass-passivated die construction and is housed in a KBP plastic package with four terminals. The device supports a maximum repetitive peak reverse voltage of 100 V and an average rectified output current of 2.0 A at 50°C ambient temperature. It exhibits a low forward voltage drop and high surge current capability, rated up to 65 A for an 8.3 ms single half-sine-wave pulse. The component operates within a junction temperature range of -55°C to 150°C.

Feature Summary

• Glass passivated die construction for enhanced reliability
• High case dielectric strength of 1,500 V RMS
• Low reverse leakage current characteristics
• Surge overload rating supporting high transient currents

Applications

• General-purpose AC to DC conversion circuits
• Power supply units requiring isolated bridge rectification
• Industrial control systems utilizing resistive or inductive loads

Procurement Notes

Verify the specific ordering suffix to confirm lead-free status and packaging configuration, as variations exist within the KBP series. Confirm RoHS compliance and REACH status against current regulatory requirements before integration. Ensure the selected variant matches the required thermal management specifications for the intended operating environment.

Selection Notes

Select this component when a 100 V blocking voltage and 2.0 A continuous current are required in a through-hole KBP package. Consider derating the current by 20% if the application involves capacitive loads rather than standard resistive or inductive types. Verify that the 65 A surge rating exceeds the expected inrush current peaks of the target circuit design.

Part Context

The KBP201G belongs to the KBP series of single-phase glass-passivated bridge rectifiers produced by SMC Diode Solutions. This series is designed for general-purpose applications requiring robust performance in compact through-hole packages. The KBP201G specifically provides a 100 V reverse voltage rating, distinguishing it from other variants in the family such as the KBP205G or KBP301GTB which offer different voltage or current capabilities.

Replacement Considerations

Direct replacements must match the 100 V reverse voltage, 2.0 A current rating, and KBP package footprint. Verify pinout compatibility and thermal resistance values. Alternative manufacturers may offer equivalent glass-passivated bridge rectifiers in the KBP format.
