Product details

Gate drive and switching — what the 4.5 V / 10 V drive voltage tells you

The 65.5 nC typical gate charge at 10 V means the gate driver needs to source and sink that charge within the switching period; a 1 A driver will turn the FET on in about 65 ns, but the 3525 pF input capacitance at 25 V drain-source adds to the driver's reactive load. For PWM frequencies above 20 kHz, budget gate-drive power dissipation and switching losses in the total loss calculation.

Temperature range and qualification — where this part is used

For designs targeting ISO 26262 or customer-specific reliability programs, the AEC-Q101 lot traceability and PPAP documentation should be available from STMicroelectronics.

Frequently asked questions

Is STD45P4LLF6AG RoHS compliant?

The part is listed with a Tape & Reel and Cut Tape packaging option, consistent with RoHS-compliant supply. The AEC-Q101 qualification and STMicroelectronics' standard RoHS declaration apply — verify the specific date code lot certificate if your compliance audit requires it.
