Applications
- Computer peripheral circuits
- Mobile phone power management
- Portable electronic device rectification
Procurement Notes
Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status via official datasheets. Ensure storage conditions remain within specified limits to maintain performance integrity. Validate package markings against manufacturer specifications prior to assembly integration.
Selection Notes
Select this component for low-voltage, low-current rectification tasks requiring compact footprint. Consider thermal management constraints due to the small SOT-346 package. Evaluate reverse voltage margins relative to circuit operating conditions. Compare forward voltage drops against alternative Schottky devices for efficiency optimization.
Part Context
This part belongs to ROHM's standard-grade Schottky diode series optimized for portable consumer electronics. It serves as a compact solution for signal or power rectification where space is limited. The product line emphasizes balance between low VF and low IR characteristics.
Replacement Considerations
ROHM may provide new alternative products for this component. Verify compatibility with existing PCB layouts and electrical parameters before substituting with similar Schottky diodes from other manufacturers.
