KBP2005-BP

Overview

The KBP2005-BP is a single-phase bridge rectifier from Micro Commercial Components, rated for a maximum recurrent peak reverse voltage of 50V and an average forward current of 2.0A at a case temperature of 105°C. It features a glass passivated die construction within a molded plastic case classified as UL 94V-0. The device supports a peak forward surge current of 60A for an 8.3ms half-sine wave pulse. Electrical characteristics include a maximum forward voltage drop of 1.1V per element at 2.0A and a maximum DC reverse current of 5µA at 25°C. The component operates within a temperature range of -55°C to +150°C.

Feature Summary

• Glass passivated die construction provides reliable performance under varying thermal conditions.
• Molded plastic case material meets UL flammability classification rating 94V-0.
• Designed specifically for printed circuit board mounting applications.

Applications

• Printed circuit board assembly in power supply circuits
• AC to DC conversion stages requiring low voltage blocking
• General purpose rectification in consumer electronics

Procurement Notes

Verify the authenticity of the KBP2005-BP by purchasing exclusively from Micro Commercial Components or their authorized distributors. Counterfeit components pose significant risks to circuit reliability. Ensure that the ordering suffix "-BP" corresponds to RoHS compliance as defined in the manufacturer's documentation. Confirm package integrity upon receipt to prevent damage to the lead frame or casing during handling and storage.

Selection Notes

Select the KBP2005-BP when a 50V peak reverse voltage rating is required for single-phase rectification. This component is suitable for designs needing a 2.0A average forward current capability with a compact through-hole footprint. Consider the thermal derating curves provided in the datasheet to ensure safe operation above ambient temperatures. Verify that the 60A surge current rating aligns with the expected inrush currents in the target application.

Part Context

The KBP2005-BP belongs to the KBP series of bridge rectifiers manufactured by Micro Commercial Components. This series spans voltage ratings from 50V to 1000V, sharing a common physical outline designated as KBPR. The "-BP" suffix indicates that the specific unit is lead-free and RoHS compliant. The series utilizes standard silicon technology optimized for general-purpose rectification tasks in commercial and industrial equipment.

Replacement Considerations

Direct replacements must match the 50V reverse voltage, 2A forward current, and KBPR package dimensions. Verify that substitute components offer equivalent surge current ratings and forward voltage drops. Ensure any alternative parts also meet UL 94V-0 flammability standards if used in certified assemblies.

FAQ

What is the typical junction capacitance per element?

The typical junction capacitance per element is 25pF at 4V reverse DC bias and 1MHz frequency.

How does the average forward current change with case temperature?

The average forward current is rated at 2.0A at a case temperature of 105°C. Derating curves indicate that the current capacity decreases as the case temperature increases beyond this point.

What is the thermal resistance from junction to case?

The typical thermal resistance from junction to case is 10°C/W.
