KBPC5012FP

Overview

The KBPC5012FP is a single-phase diode bridge rectifier manufactured by Diotec Semiconductor. It features an average forward current (IFAV) of 50 A and a repetitive peak reverse voltage (VRRM) of 1200 V. The device utilizes fast-on terminals for connection and operates with a maximum junction temperature of 150°C. Typical electrical characteristics include a forward voltage (VF) below 1.1 V, a peak forward surge current (IFSM) of 400 A at 50 Hz or 450 A at 60 Hz, and a reverse recovery time (trr) of approximately 1500 ns. The component is housed in a plastic case with an isolated aluminum baseplate.

Feature Summary

• Four diodes integrated in a bridge configuration within a plastic package featuring an isolated aluminum baseplate
• Equipped with FP fast-on terminals compatible with 6.3mm connectors, allowing for alternative solder assembly
• Compliant with RoHS directives under exemption 7a-I and meets REACH standards regarding conflict minerals

Applications

• 50/60 Hz mains rectification
• Commercial power supplies
• Industrial grade applications

Procurement Notes

Verify the specific ordering suffix to confirm terminal type and qualification status. The standard FP suffix indicates fast-on terminals, while WP denotes wire terminals. Suffixes -Q and -AQ indicate AEC-Q101 compliance or qualification respectively. Confirm packaging details, as FP versions are typically packed in cardboard trays containing 240 units. Ensure the design accounts for forced cooling to achieve the rated 50 A output current.

Selection Notes

Select this component when a high-voltage single-phase bridge rectifier is required for commercial or industrial environments. The 1200 V rating suits high-line voltage applications. Consider thermal management carefully, as the 50 A rating assumes forced cooling; derating is necessary for natural convection. Verify that the PCB layout accommodates the fast-on terminals or allows for direct soldering if preferred over mechanical connectors.

Part Context

This part belongs to the KBPC series of silicon bridge rectifiers from Diotec Semiconductor. The series includes variants with different voltage ratings and current capacities, such as KBPC10, KBPC15, KBPC25, and KBPC35. The KBPC5012FP specifically represents the 50 A current class with a 1200 V blocking capability, sharing the same physical dimensions and mounting style as other members of the KBPCxxxx family.

Replacement Considerations

Direct substitutes within the same manufacturer's lineup include other KBPC50xxFP models with matching current ratings but different voltage capabilities, such as KBPC5010FP (1000 V). Cross-manufacturer replacements must match the 50 A IFAV, 1200 V VRRM, KBPC-4 package outline, and fast-on terminal configuration.
