Overview
The B0520LWF is a surface-mount Schottky barrier rectifier manufactured by Taiwan Semiconductor Corporation. It features an SOD-123F plastic package with matte tin-plated terminals. The device supports a mean forward current of 0.5 A and a repetitive peak reverse voltage of 20 V. Electrical characteristics include a low forward voltage drop, typically ranging from 385 mV to 430 mV at specified currents, and a non-repetitive peak forward surge current capability of up to 5.5 A. The component operates within a junction temperature range of -65°C to +175°C.
Feature Summary
- Low forward voltage design for high efficiency
- Surface mount construction in SOD-123F package
- Lead-free and halogen-free green compound option
Applications
- DC-DC converters
- Power supply circuits
- Polarity protection applications
Procurement Notes
Verify the specific suffix 'G' on the packing code or date code prefix if halogen-free compliance is required. Confirm the package type matches the SOD-123F specification. Ensure the ordering information aligns with the manufacturer's current datasheet revision to guarantee correct electrical parameters and mechanical dimensions.
Selection Notes
Select this component for designs requiring low power loss and high current capability in a small outline plastic package. The SOD-123F form factor suits space-constrained PCB layouts. Verify thermal resistance requirements against the application's ambient temperature conditions to ensure reliable operation within the specified junction temperature limits.
Part Context
This part belongs to the B0520 series of Schottky barrier rectifiers. It shares functional similarities with other low-voltage, low-current surface-mount diodes but is distinguished by its specific SOD-123F packaging and Taiwan Semiconductor manufacturing specifications. The series targets general-purpose rectification where low forward voltage is critical.
Replacement Considerations
Cross-reference with Diodes Incorporated B0520LW or Jiangsu Changjiang Elec B0520LW for pin-compatible alternatives. Verify that substitute parts meet the same 20 V reverse voltage and 0.5 A forward current ratings.
