Vishay Si846xDB MICRO FOOT power MOSFET

Vishay Si846xDB MICRO FOOT® Power MOSFETs

The Vishay Siliconix 20-V p-channel Si8461DB and Si8465DB MICRO FOOT Power MOSFETs can be used for load switch, battery switch, and charger switch applications in a wide range of portable devices. Their small size and height reduce the space occupied by power management circuitry and enable more functionality. Compared to the next smallest chipscale power MOSFET on the market, the 1-mm by 1-mm by 0.548-mm MICRO FOOT has a 9% smaller footprint.


On-resistance for the Vishay Si8461DB MICRO FOOT Power MOSFET is 0.1 Ω at a 4.5-V gate drive, which represents a tenfold improvement over non-chipscale devices with similar footprint dimensions and thus provides a significant opportunity to conserve battery life in portable devices. In addition to the 4.5-V rating, the Vishay Si8461DB MICRO FOOT Power MOSFET is specified for maximum on-resistance values at 2.5 V, 1.8 V, and 1.5 V, which aligns the device with the smaller input signals common in portable systems. For applications requiring higher input voltages such as charger switches, the Vishay Si8465DB MICRO FOOT Power MOSFET has a gate-to-source voltage of 12 V; on-resistance is 0.104 Ω at a 4.5-V gate drive and 0.148 Ω at 2.5 V.
