KBPC801

Overview

The Diotec Semiconductor KBPC801 is a single-phase silicon bridge rectifier designed for commercial and industrial applications. It features an average forward current rating of 8 A at an ambient temperature of 50°C and supports a peak repetitive reverse voltage of 100 V. The device exhibits a maximum forward voltage drop of 1.2 V at 4 A and a low leakage current below 5 µA at 25°C. Thermal performance includes a junction-to-case resistance under 3.3 K/W and a junction-to-ambient resistance under 10 K/W. It operates within a temperature range of -50°C to +150°C and withstands surge currents up to 150 A.

Feature Summary

• Robust thermal management capabilities with low junction-to-case resistance for efficient heat dissipation in flange-mounted configurations.
• High surge current handling capacity suitable for absorbing transient electrical spikes during power-up or fault conditions.
• Low leakage current characteristics ensuring minimal energy loss and stable operation under high reverse bias voltages.

Applications

• General-purpose AC to DC power supply circuits
• Battery charging systems requiring moderate current ratings
• Industrial control equipment power stages

Procurement Notes

Verify the specific manufacturer source, as the KBPC801 designation appears across multiple vendors including Frontier and Pingwei. Confirm that the component matches the Diotec Semiconductor datasheet specifications, particularly the 8 A current rating and 100 V reverse voltage, before procurement. Ensure the package type aligns with the required mounting method.

Selection Notes

Select this component when a standard single-phase bridge rectifier with an 8 A continuous current capability is required. The 100 V reverse voltage rating makes it suitable for low-voltage AC conversion tasks. Consider the thermal resistance values if operating near the upper limit of the specified ambient temperature range.

Part Context

This part belongs to the KBPC800...KBPC810 series from Diotec Semiconductor, which shares identical physical dimensions and mounting styles but varies in voltage ratings. The KBPC801 specifically denotes the 100 V variant within this family of flange-mount bridge rectifiers.

Replacement Considerations

Direct substitutes include other KBPC801 parts from different manufacturers such as Frontier or Pingwei, provided they meet the same 8 A/100 V electrical specifications. Cross-referencing with Diotec's KBPC800 series documentation ensures compatibility.
