Procurement Notes
Verify the specific package type and datasheet revision before ordering, as this component is supplied as a bare die. Confirm that the application design accommodates the surface-mount die form factor and thermal requirements. Ensure compatibility with the intended PCB layout for die attachment. Check for any recent product change notifications regarding packaging or material composition updates from the manufacturer.
Selection Notes
Select the CD649 when a high-voltage rectifier with a 720 V rating and 400 mA current capacity is required in a surface-mount die format. Consider its wide temperature range and low leakage characteristics for reliable operation in harsh conditions. Evaluate the physical dimensions and mounting requirements against the available board space. Compare performance metrics with alternative diodes if higher current or lower voltage ratings are needed.
Part Context
The CD649 belongs to Microchip Technology's portfolio of discrete semiconductor diodes. It is categorized under standard rectifiers designed for general-purpose applications. This component complements other high-voltage diode offerings from the manufacturer, providing options for designers needing robust voltage handling in a small footprint.
