Overview
The RB548WMFHTL is a Schottky barrier diode manufactured by ROHM Semiconductor, designed for surface mount applications in the SOT-416FL-3 package. It features a dual common cathode configuration with silicon epitaxial planar construction. Key electrical parameters include a maximum repetitive reverse voltage of 30V and an average forward rectified current of 100mA. The device exhibits a typical forward voltage of 450mV at rated current and a low reverse leakage current of 500nA. It supports a forward surge current of 500mA and operates at junction temperatures up to +150°C.
Feature Summary
- Dual common cathode configuration within a compact SMD package
- Low forward voltage drop for improved efficiency
- High reliability suitable for automotive environments
Applications
- Low current rectification circuits
- Automotive electronic systems requiring AEC-Q101 compliance
- DC-DC converter output stages
Procurement Notes
Verify the specific suffix HTL against official ROHM documentation to confirm tape and reel packaging specifications. Ensure the part number matches the exact voltage and current ratings required for the target circuit design. Cross-reference the RoHS status and automotive qualification details directly from the manufacturer's datasheet before finalizing procurement orders.
Selection Notes
Select this component when a dual Schottky diode in a small footprint is required for low-voltage, high-efficiency applications. The 30V rating and 100mA current capacity define its operational limits. Consider the thermal performance and package size constraints relative to alternative single-diode solutions or larger packages offering higher current handling capabilities.
Part Context
This component belongs to ROHM's Schottky Barrier Diode series, specifically optimized for automotive and industrial applications. The RB548WMTL variant shares similar electrical characteristics but may differ in packaging or qualification standards. The RB548WFH represents a different package type within the same functional family, offering comparable performance in an EMD3 housing.
Replacement Considerations
The RB548WFH is a documented substitute with identical pinout and package dimensions. Verify that the replacement meets all electrical requirements, particularly regarding reverse voltage and forward current ratings, before implementation.
