IRF5805TR-VB Product details
Back to previous pageProduct introduction：
Imagine this: you are designing a portable battery-powered device with a compact system space, yet you need to handle a load switch for a negative voltage rail or reverse battery protection. Ordinary PMOS either has a high voltage drop or occupies too much board area. The VBsemi IRF5805TR-VB is designed for this—it integrates a -30V drain-source voltage, -4.8A current capability, and a low 49mΩ on-resistance into a compact SOT23-6 package, making negative voltage power management design simpler and more efficient.

Domain and module applications：
Load Switch / Power Path Management – Acts as a high-side P-channel switch for on/off control of negative voltage rails or battery circuits, with low voltage drop and temperature rise.
Battery Protection Board – Quickly cuts off the discharge circuit during overcharge, over-discharge, or overcurrent, protecting cell safety.
DC-DC Converter – Used as a P-channel switch in synchronous boost or buck topologies, improving light-load efficiency.
Portable Device Power Management – Serves as a negative voltage regulator or power switch in power banks and handheld terminals, saving PCB space.
Motor Drive / Low-Power Inverter – Forms a complementary drive stage with a low-side N-MOS, suitable for small power loads like fans and pumps.
LED Driver Circuit – Used for negative voltage constant current control or PWM dimming, fast response, no flicker.
Industrial Sensor Interface – Withstands negative voltage surges, providing stable power rail protection. One-sentence summary: IRF5805TR-VB is not an ordinary PMOS; it is your "compact switch expert" and "low-loss champion" in negative voltage power designs.
