Overview
The KMB22S is a 2.0A surface mount Schottky barrier bridge rectifier in the MB-S package. It features a peak repetitive reverse voltage of 20V, a working peak reverse voltage of 14V, and an RMS reverse voltage of 14V. The average rectified output current is 2.0A at 90°C lead temperature, with a non-repetitive peak forward surge current of 50A. Forward voltage is typically 0.70V at 2.0A. Peak reverse current is 20mA at 25°C and 10mA at 100°C. Thermal resistance is 50°C/W. Operating and storage temperatures range from -65°C to +150°C.
Feature Summary
- Schottky barrier chip construction for low power loss and high efficiency
- Ideal suitability for automatic assembly processes
- High surge current capability per MIL-STD-202 standards
- Molded plastic case material with UL flammability classification
Applications
- Low voltage DC-DC converter circuits
- Power supply freewheeling diodes
- Reverse polarity protection in automotive electronics
Procurement Notes
Verify the manufacturer designation on the datasheet header against the requested brand SMC Diode Solutions, as the provided source attributes the KMB22S to Zibo Seno Electronic Engineering Co., Ltd. Confirm the specific ordering suffix matches the required voltage rating and RoHS compliance status before procurement.
Selection Notes
Select this component when a 2.0A bridge rectifier with a 20V maximum reverse voltage is required. Ensure the application operates within the -65°C to +150°C junction temperature range. Verify that the 50A surge current capacity meets the circuit's inrush requirements during startup conditions.
Part Context
The KMB22S belongs to the KMB22 series of surface mount Schottky bridge rectifiers. This series includes variants with different voltage ratings, such as the KMB23S through KMB25S, allowing designers to select appropriate blocking voltages while maintaining consistent current handling and package dimensions for board layout standardization.
Replacement Considerations
Direct substitutes must match the 2.0A current rating, 20V reverse voltage, and MB-S package footprint. Verify thermal resistance and forward voltage characteristics to ensure equivalent performance in low-voltage applications.
