KBPC3506W

Overview

The GeneSiC Semiconductor KBPC3506W is a single-phase silicon bridge rectifier designed for high-efficiency AC-to-DC conversion. It features a maximum average forward rectified current (IO) of 35 A at a case temperature of 55 °C and supports a peak forward surge current (IFSM) of 400 A under half-sine-wave conditions. The device offers a repetitive peak reverse voltage (VRRM) of 600 V with a DC blocking voltage of 600 V. Electrical characteristics include a maximum instantaneous forward voltage per leg of 1.1 V and a typical junction capacitance of 300 pF. The component operates within a junction temperature range of -55 °C to +150 °C, utilizing the KBPC-W package configuration.

Feature Summary

• Utilizes a metal case encapsulated in a bridge structure for robust mechanical mounting via screw holes.
• Constructed using silicon junction technology to ensure high efficiency and non-ESD sensitivity.
• Features low thermal resistance of 1.4 °C/W for effective heat dissipation during operation.

Applications

• AC to DC power supply circuits
• General-purpose rectification in industrial equipment
• Power supplies for resistive or inductive loads

Procurement Notes

Verify that the specific ordering suffix 'W' corresponds to the KBPC-W package variant as defined in the official datasheet. Confirm the manufacturer designation matches GeneSiC Semiconductor records. Ensure the procurement documentation explicitly lists the 600 V reverse voltage rating and 35 A current capacity to avoid substitution errors with similar series components.

Selection Notes

Select this component when a 35 A continuous current rating and 600 V blocking voltage are required for single-phase applications. The KBPC-W package requires through-hole mounting compatible with #10 screws. Consider the 1.4 °C/W thermal resistance for heatsink design calculations. Derate the forward current by 20% if the application involves capacitive loads rather than standard resistive or inductive configurations.

Part Context

This part belongs to the KBPC3506T/W through KBPC3510T/W family of single-phase silicon bridge rectifiers. The 'W' suffix specifically denotes the KBPC-W package type, distinct from the KBPC-T package used in the 'T' variant. All members of this series share identical electrical ratings but differ in physical package dimensions and terminal configurations.

Replacement Considerations

Direct replacements must match the 35 A IO, 600 V VRRM, and KBPC-W package form factor. Verify that substitute components maintain the same 1.4 °C/W thermal resistance and -55 °C to +150 °C operating temperature range to ensure circuit reliability.
