AF4407PSLA-VB Product details
Back to previous pageProduct introduction：
Are you designing a high-power-density power module where board space is tight, yet you need to handle high current switching on the negative rail? Standard PMOS either has too much voltage drop or complex drive logic. The VBsemi AF4407PSLA-VB is designed for this – it packs -30V withstand voltage, -11.6A current capability, and an ultra-low on-resistance of 11mΩ into the compact SOP8 package, making negative voltage switch design uncompromising.

Domain and module applications：
Battery Protection Board / Negative Voltage Switch – Used as the main P-channel switch, quickly cuts off the circuit during over-discharge or overcurrent, reducing conduction losses and extending battery life.
Load Switch / Power Path Management – Used for negative terminal on/off control of system power, low RDS(on) results in less voltage drop and temperature rise.
DC-DC Synchronous Rectification – Acts as a high-side or low-side switch in buck or boost topologies, improving conversion efficiency.
Motor Drive / Power Tools – Utilizes low internal resistance and fast switching capability for high-current commutation and smooth speed control.
Automotive Electronics / Industrial Control – Withstands -30V negative voltage fluctuations, providing stable and controllable power paths for sensors and actuators.
LED Lighting / Ambient Light Strips – Used as a switch in negative voltage constant current drivers, reducing power consumption and improving brightness consistency.
Portable Devices / Power Banks – The compact SOP8 package combined with high current capability is suitable for portable designs with strict space and thermal requirements.
One-sentence summary: The AF4407PSLA-VB is not an ordinary P-channel MOS tube; it is your 'low-resistance switch' and 'efficiency tool' in negative voltage power and load management.
