6.8. Key Parameters for Application Suitability

Try these first

1. 1.

   What does threshold voltage (Vth) signify in a MOSFET?

   Hint

   Think about what it means to 'activate' a switch.

2. 2.

   Name one effect of high on-resistance (RDS(on)).

   Hint

   Consider how resistors behave in a circuit.

3. 3.

   What is the threshold voltage (Vth) in a MOSFET?

   Hint

   Think about what voltage is necessary to 'flip the switch' on the device.

4. 4.

   True or False: Lower on-resistance (RDS(on)) improves power efficiency.

   • True
   • False

   Hint

   Consider how resistance plays a role in energy loss.

5. 5.

   A designer must choose a MOSFET for a high-speed switching application where maintaining power efficiency is critical. What aspect of MOSFETs should the designer primarily focus on and why?

   Hint

   Consider what keeps the flow responsive in devices.

6. 6.

   Explain how a high breakdown voltage (VDS) MOSFET selection could prevent device failures in an application experiencing unexpected voltage spikes.

   Hint

   Think about the safety margins in engineering designs.
