GPIHV7DK is listed in the Single FETs, MOSFETs range at ChipApex. The manufacturer field lists GaNPower. Its product description is GaNFET N-CH 1200V 7A TO252. Review the specifications below when checking this part for your BOM.
The GPIHV7DK is an N-channel 1200V GaN Power HEMT in a TO-252 package. It features a maximum drain-source breakdown voltage of 1200V and a continuous drain current of 7A at 25°C. The device exhibits an ultra-low on-state resistance (Rdson) of 158 mΩ and extremely low input capacitance (Ciss) of 90 pF. Gate charge (Qg) is 3.1 nC, with zero reverse recovery charge (Qrr). Operating temperature ranges from -55°C to 150°C.
Verify the specific datasheet version prior to procurement, as the provided documentation indicates this is a preliminary release. Confirm that the TO-252 packaging aligns with your PCB footprint requirements. Ensure gate drive circuits are optimized for the device's high dv/dt characteristics and low threshold voltage to prevent false triggering.
Select this component when designing systems requiring high efficiency and compact form factors. The 1200V rating suits medium-voltage topologies. Consider the negative gate voltage tolerance (-12V) for robust turn-off. Evaluate thermal management needs given the junction-to-ambient resistance, ensuring adequate copper area for heat dissipation in surface-mount layouts.
This part belongs to GaNPower's E-mode GaN on silicon technology lineup. It replaces traditional silicon MOSFETs or IGBTs in applications demanding higher switching frequencies. The TO-252 package provides a balance between thermal performance and mounting convenience compared to smaller DFN packages.
Direct pin-to-pin replacement with silicon devices is not recommended due to different gate driving requirements and high slew rates. Designers must implement specialized drivers and optimized PCB layouts to manage parasitic inductance effectively.
No, the device operates in both first and third quadrants without inherent PN junction reverse recovery issues. However, dead time power loss should be managed due to its Vsd voltage.
Yes, paralleling is supported due to the positive temperature coefficient of Rdson and threshold voltage, which aids in current sharing.
