Single Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging orientation and quantity. The 'TRL' suffix indicates a tape and reel with left-oriented leads, while 'TRR' denotes right-oriented leads. Confirm RoHS compliance and halogen-free status via the '-M3' designation. Ensure thermal management aligns with the specified junction-to-case thermal resistance values during integration.

Single Diodes Selection Notes

Select this component when low forward voltage drop and small board space are critical requirements. The DPAK package provides a balance between current handling capability and compact form factor. Evaluate thermal performance based on the maximum allowable case temperature curves provided in the datasheet. Consider the 400 A surge rating for applications involving transient load conditions or startup currents.

Single Diodes Part Context

This part belongs to Vishay's high-performance Schottky rectifier series, specifically utilizing Trench MOS barrier technology. The 'W' in the part number identifies the D-PAK package style, while 'Q' denotes the Schottky series. The device is engineered for applications demanding high frequency operation and minimal power losses due to its low forward voltage characteristics.

Single Diodes Replacement Considerations

Direct replacements must match the 10 A current rating, 45 V reverse voltage, and DPAK (TO-252AA) package outline. Verify that alternative components offer comparable forward voltage drops and thermal resistance values to maintain circuit efficiency and reliability without redesigning the PCB layout.
