Detailed parameter description and application introduction:.
1. Channel type: P-channel.
- This means that this is a P-channel MOSFET, which is usually used in applications that need to control negative voltage supplies. .
.
2. Rated voltage (VDS): -30V.
- This is the maximum negative voltage that the trench MOSFET can withstand, indicating that it is suitable for circuits that need to handle up to -30V. .
.
3. Current Rating (ID): -7A.
- This is the current rating of the trench MOSFET, indicating the high current load it can handle. .
.
4. Static Drain-Source Resistance (RDS(ON)): .
- RDS(ON) is the resistance of the trench MOSFET in the on state. At 10V, its resistance is 23mΩ, while at 4.5V it is 29mΩ and at 2.5V it is 66mΩ. This indicates that in the on state, its resistance is very low, which helps to reduce power consumption and heat. .
.
5. Gate-Source Voltage Rating (Vgs): 20V (±V).
- This indicates that the gate-source voltage is rated to be between plus and minus 20V. The gate-source voltage is used to control the on and off states of the MOSFET. .
.
6. Threshold Voltage (Vth): -1.37V.
- This is the threshold voltage of the channel MOSFET, which indicates the voltage that needs to be applied to the gate to make the device start to conduct. .
