Overview
The RB548WMTL is a Schottky barrier diode manufactured by ROHM Semiconductor, designed for surface mount applications in the SOT-416FL-3 package. It features a dual configuration with silicon technology and supports a maximum repetitive reverse voltage of 30 V. The device handles a forward current of 100 mA and exhibits a low forward voltage of 450 mV. Additional electrical characteristics include a forward surge current of 500 mA, a reverse current of 500 nA, and a maximum operating temperature of +150 C.
Feature Summary
- Dual Schottky barrier diode structure for efficient rectification
- Low forward voltage characteristic to minimize power loss
- High thermal stability suitable for elevated temperature environments
Applications
- General purpose low current rectification
- Power supply input protection circuits
- Signal detection in consumer electronics
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and tape specifications. Confirm RoHS compliance status through the latest datasheet revision. Cross-reference the component marking code with the physical package to prevent counterfeit substitution during assembly.
Selection Notes
Select this component when a compact dual Schottky diode solution is required for low-voltage applications. The SOT-416FL-3 package offers space efficiency compared to larger discrete options. Ensure the 30 V reverse voltage rating exceeds the peak circuit voltage and the 100 mA forward current meets load requirements.
Part Context
This component belongs to ROHM's standard Schottky diode portfolio, which emphasizes high reliability and small form factors. The RB548 series is engineered for general electronic equipment where low forward voltage drop and fast switching speeds are critical. It serves as a common alternative to other industry-standard small-signal Schottky devices.
Replacement Considerations
The part number alias RB548WM indicates potential interchangeability within the same series. Verify pinout compatibility and electrical parameters before substituting with similar dual Schottky diodes from other manufacturers.
