- High efficiency due to low power loss
- Fast switching capability with minimal reverse recovery charge
Applications
- DC-DC converters
- Power supply circuits
- Reverse polarity protection
Procurement Notes
Verify the specific suffix -7-79 against official Diodes Incorporated documentation to confirm tape and reel packaging specifications. Confirm RoHS compliance status through the latest datasheet or certificate of conformity. Ensure the component matches the required SOD-323 footprint dimensions for PCB layout compatibility.
Selection Notes
Select this component when a compact surface-mount solution is required for low-voltage, high-current rectification. The SOD-323 package offers space savings compared to larger through-hole alternatives. Consider the 40 V rating and 1 A current capacity relative to the circuit's peak operating conditions to ensure adequate safety margins.
Part Context
This part belongs to the Diodes Incorporated discrete diode portfolio, specifically within the Schottky rectifier category. The manufacturer specializes in semiconductor solutions for power management and signal processing. The B140WS series is engineered for general-purpose rectification in consumer electronics and industrial equipment.
Replacement Considerations
Consult official substitution guides from Diodes Incorporated for verified equivalents. Cross-reference pinout configurations and thermal characteristics before replacing. Generic Schottky diodes may not match the exact forward voltage or reverse leakage specifications.
