Power MOSFET - Vishay

ruggedized device design, low on-resistance and cost-effectiveness. The TO-220AB package is universally preferred for all commercial-industrial applications at power dissipation levels to approximately 50 W. The low thermal resistance and low package cost of the TO-220AB contribute to its wide acceptance throughout the industry. Notes a.

AND9093 - Using MOSFETs in Load Switch Applications

The load switch is controlled by the system, and connects or disconnects a voltage rail to a specific load. By turning unused circuitry off, the system as a whole can run more efficiently. The load switch provides a simple means to power a load when it is in demand and allows the system to maximize performance. Load Switch Basics

RF Switch Design - Worcester Polytechnic Institute

2.1 FET-based RF switch designs There exist three major FET switch topologies: series, shunt, and combinational. Combinational switches are common in cellular applications, as they tend to be less lossy than the alternatives. In Figure 2.1, a combinational switch is shown. When a control voltage is held high, the series FET for its corresponding

P-Channel MOSFETs, the Best Choice for High-Side Switching

P-Channel MOSFETs, the Best Choice for High-Side Switching Historically, p-channel FETs were not considered as useful as their n-channel counterparts. The higher resistivity of p-type silicon, resulting from its lower carrier mobility, put it at a disadvantage compared to n-type silicon. Getting n-type performance out of p-type FETs has meant
