KBP08G

Overview

The KBP08G is a single-phase standard recovery bridge rectifier manufactured by Diodes Incorporated. It provides an average rectified output current of 1.5 A at a case temperature of +105°C and supports a maximum repetitive peak reverse voltage of 800 V. The device features a forward voltage of 1.1 V maximum at the rated current and a non-repetitive peak forward surge current rating of 40 A for an 8.3 ms half-sine wave. Operating temperatures range from -55°C to +150°C, with leakage currents specified at 5 µA at +25°C and 500 µA at +125°C.

Feature Summary

• Glass passivated die construction ensures long-term reliability and stability under various operating conditions.
• High case dielectric strength of 1500 VRMS provides robust insulation and protection against electrical stress.
• Lead-free finish with RoHS compliance meets environmental standards while maintaining solderability per MIL-STD-208.

Applications

• Printed circuit board applications requiring compact bridge rectification solutions
• General-purpose AC to DC conversion in consumer electronics
• Power supply units utilizing standard recovery characteristics

Procurement Notes

Verify the ordering suffix 'G' confirms lead-free and RoHS compliant status as defined by Diodes Incorporated. Confirm the package type is KBP and the packing quantity matches the standard tube configuration of 35 pieces. Ensure the component date code aligns with current inventory requirements before finalizing procurement orders.

Selection Notes

Select the KBP08G when an 800 V peak reverse voltage rating is required for single-phase bridge rectification. Ensure the application operates within the 1.5 A average current limit at +105°C case temperature. Verify that the 40 A surge current capability is sufficient for the specific circuit startup or fault conditions encountered.

Part Context

The KBP08G belongs to the KBP005G through KBP10G series of 1.5 A standard recovery bridge rectifiers. This family shares identical mechanical dimensions, thermal characteristics, and general electrical performance profiles, differing primarily in their maximum repetitive peak reverse voltage ratings ranging from 50 V to 1000 V.

Replacement Considerations

Cross-reference with other manufacturers offering KBP package bridge rectifiers rated at 1.5 A and 800 V. Verify pinout compatibility and thermal resistance values to ensure equivalent performance in existing designs without modifying the printed circuit board layout.

FAQ

What is the maximum non-repetitive peak forward surge current?

The maximum non-repetitive peak forward surge current is 40 A for an 8.3 ms single half-sine wave superimposed on the rated load.

Is the KBP08G suitable for automotive applications?

Standard KBP08G parts are not automatically qualified for automotive use. For AEC-Q100/101/104/200 qualification and IATF 16949 manufacturing, direct contact with Diodes Incorporated is required.

What is the typical junction-to-case thermal resistance?

The typical thermal resistance from junction to case is 18 °C/W per element, measured with the device mounted on a 75mm x 75mm x 1.6mm copper plate heatsink.
