Overview
The RB558WTL is a Schottky barrier diode manufactured by ROHM Semiconductor, designed for surface-mount applications. It features a dual common cathode configuration within an SOT-416FL (SC-75A) package. The device utilizes silicon technology and supports a maximum repetitive reverse voltage of 30V with an average forward rectified current of 100mA. Key electrical characteristics include a maximum forward voltage of 450mV at the rated current and a low reverse leakage current of 500nA. It withstands a forward surge current of 500mA and operates at junction temperatures up to +150°C.
Feature Summary
- Dual common cathode configuration for space-efficient circuit design
- Low forward voltage drop to enhance energy efficiency
- High thermal stability supporting elevated operating temperatures
Applications
- General purpose rectification in consumer electronics
- Power supply input protection circuits
- Freewheeling diodes in low-current DC-DC converters
Procurement Notes
Verify the specific ordering suffix against the official ROHM datasheet to ensure the correct packaging format, such as cut tape or reel quantities. Confirm that the component meets RoHS compliance requirements for your target market. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.
Selection Notes
Select this component when a compact dual-diode solution is required for low-voltage, low-current applications. The SOT-416FL package offers a small footprint suitable for dense PCB layouts. Ensure the application current does not exceed the 100mA average rating and that the reverse voltage stress remains below 30V to maintain reliable operation under specified thermal conditions.
Part Context
This component belongs to the RB548 series of Schottky barrier diodes from ROHM Semiconductor. The series is characterized by its small signal capabilities and suitability for portable devices. The RB558WTL variant specifically denotes the 30V rating within this family, sharing similar physical dimensions and performance profiles with other members like the RB548WM while differing in voltage specifications.
Replacement Considerations
The RB548WM is listed as an alias for this part number. Verify pinout compatibility and electrical ratings when substituting with generic equivalents. Ensure any replacement maintains the dual common cathode configuration and fits within the SOT-416FL package constraints.
