Detailed parameter description and application introduction:.
1. Channel type: N channel.
- This means that this is an N-channel MOSFET commonly used in electronic equipment, especially applications that require the control of a positive voltage power supply. .
.
2. Rated voltage (VDS): 30V.
- This is the maximum voltage that the channel MOSFET can withstand, indicating that it is suitable for circuits that need to handle up to 30V. .
.
3. Rated current (ID): 6.8A.
- This is the current rating of the channel MOSFET, indicating the medium current load it can handle. .
.
4. Static drain-source resistance (RDS(ON)): .
- RDS(ON) is the resistance of the channel MOSFET in the on-state. At 10V it has a resistance of 33mΩ and at 4.5V it is 45mΩ. This shows that in the on-state, its resistance is relatively low, helping to reduce power consumption and heat. .
.
5. Gate-source voltage rating (Vgs): 20V (±V).
- This means that the rated range of gate-source voltage is plus or minus 20V. The gate-source voltage is used to control the on and off states of the MOSFET. .
.
6. Threshold Voltage (Vth): 0.9V.
- This is the threshold voltage of a channel MOSFET and represents the voltage that needs to be applied to the gate in order for the device to start conducting. .
