Overview
The KMB245S is a single-phase Schottky bridge rectifier manufactured by SMC Diode Solutions. It features a maximum repetitive peak reverse voltage of 45V and an average forward rectified current of 2A. The device exhibits a typical forward voltage drop of 550mV at 2A and a reverse leakage current of 100µA at 45V. It operates within a junction temperature range of -55°C to +150°C and utilizes a 4-SMD, Gull Wing (MBS) surface-mount package.
Feature Summary
- Utilizes Schottky technology for low forward voltage drop and high efficiency
- Designed for surface-mount assembly with a compact MBS footprint
- Capable of operation across an extended industrial temperature range
Applications
- DC-DC converter input rectification
- Power supply freewheeling circuits
- Low-voltage AC-to-DC conversion stages
Procurement Notes
Verify the specific suffix designation when ordering, as variants such as KMB245STR may indicate tape-and-reel packaging configurations distinct from standard tube or cut-tape supplies. Confirm that the procurement specification aligns precisely with the required voltage and current ratings to ensure compatibility with the target circuit design constraints.
Selection Notes
Select this component for applications requiring low forward voltage drop at moderate currents. The 45V rating suits low-voltage systems where standard silicon bridges would incur excessive power loss. Ensure the PCB layout accommodates the 4-SMD Gull Wing package dimensions and thermal requirements for reliable operation under continuous load conditions.
Part Context
This part belongs to the KMB series of Schottky bridge rectifiers from SMC Diode Solutions. The series offers various voltage ratings including 40V, 45V, and higher options, all sharing similar current handling capabilities and surface-mount form factors designed for automated assembly processes in consumer and industrial electronics.
Replacement Considerations
Direct substitutes include the KMB24S (40V variant) if system voltage margins allow. Other compatible alternatives within the same manufacturer portfolio include the KMB22S through KMB220S series, provided the reverse voltage and current specifications meet the application requirements.
