Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to ensure correct pinout and thermal pad configuration. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary. Ensure proper handling procedures for GaN devices are followed during assembly to prevent electrostatic discharge damage.

Selection Notes

Select this component for designs requiring high switching frequencies and reduced passive component size. Evaluate thermal management requirements based on the specified RθJA values. Compare total gate charge and input capacitance against controller capabilities to optimize drive strength and minimize switching losses in high-performance power stages.
