KMB14F

Overview

The MDD KMB14F is a surface-mount Schottky barrier rectifier bridge from the MBF series. It features a molded plastic body with four pins and supports a maximum repetitive peak reverse voltage of 40V and an average forward output rectified current of 1.0A at 30°C. The device exhibits a low instantaneous forward voltage of 0.55V at 1A and minimal DC reverse current. It operates within a junction temperature range of -55°C to +125°C and withstands a peak forward surge current of 30A. The component complies with RoHS standards and utilizes UL 94V-0 flammability rated materials.

Procurement Notes

Verify the original manufacturer designation as MDD when sourcing this component. Confirm that the specific part code matches the required electrical ratings, particularly the 40V reverse voltage and 1.0A current capacity. Ensure compliance with RoHS directives if environmental regulations apply to the final assembly. Check packaging specifications to confirm tape and reel quantities match production requirements.

Selection Notes

Select this component for designs requiring a compact Schottky bridge rectifier with low forward voltage drop. The 40V rating suits low-voltage AC-to-DC conversion applications. Consider the thermal resistance of 100°C/W when designing heat dissipation strategies. The SMD package facilitates automated assembly processes. Verify that the operating temperature range meets the environmental conditions of the intended application.

Part Context

This component belongs to the MBF series of SMD Schottky bridge rectifiers manufactured by MDD. The series offers various voltage and current ratings to accommodate different circuit requirements. The KMB14F specifically targets applications needing 40V blocking capability and 1.0A continuous current handling in a small footprint.

Replacement Considerations

Cross-reference part numbers such as MBFKMB16FS1006 or MBFKMB18FS1008 are available within the same series for higher voltage ratings. Ensure any substitute maintains the same package dimensions and pin configuration for direct replacement.
