Overview
The Vishay 6CWQ04FN is a surface mount Schottky rectifier in a D-PAK (TO-252AA) package. It features a center tap configuration with two independent legs. Key electrical ratings include a maximum average forward current of 7 A per device and a maximum repetitive reverse voltage of 40 V. The junction temperature range spans from -40 °C to +150 °C.
Feature Summary
- Center tap configuration for dual-leg operation
- Low forward voltage drop for efficiency
- Guard ring structure for enhanced ruggedness
- Small footprint suitable for surface mounting
Applications
- Switching power supplies
- Disk drives
- Converters
- Free-wheeling diodes
- Battery charging circuits
Procurement Notes
Verify the specific ordering suffix to confirm the packaging format, as options include tube, tape and reel, left-oriented tape and reel, or right-oriented tape and reel. Ensure the component meets lead-free requirements if specified by the suffix. Confirm that the D-PAK outline matches the target PCB footprint design.
Selection Notes
Select this component for applications requiring low forward voltage drop and high-frequency operation in a compact surface mount form factor. The center tap design supports split-rail or bridge-less topologies. Evaluate thermal resistance characteristics against the expected duty cycle and case temperature constraints to ensure reliable operation within the specified junction temperature limits.
Part Context
This part belongs to the Vishay 6CWQ series of Schottky rectifiers, originally developed by International Rectifier before its acquisition by Vishay Intertechnology. The series is designed for general-purpose rectification where low power loss and small board space are critical. The D-PAK package provides a balance between current handling capability and surface mount convenience.
Replacement Considerations
Direct substitutes must match the 40V rating, 7A current capacity, and center tap configuration in a TO-252AA package. Verify equivalent forward voltage and reverse leakage specifications to maintain circuit performance.
FAQ
What is the maximum non-repetitive surge current?
The maximum peak one-cycle non-repetitive surge current is 500 A for a 5 μs sine wave pulse.
Is this component qualified for automotive applications?
Yes, the product has been designed and qualified for AEC-Q101 Level standards.
How does the guard ring feature benefit reliability?
The guard ring provides enhanced ruggedness and contributes to long-term reliability under operating conditions.
