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 power 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. Rated Current (ID): -4.8A.
- This is the rated current of the trench MOSFET and indicates the maximum negative 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 49mΩ, while at 4.5V it is 54mΩ. This indicates that in the on state, its resistance is relatively 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 Range (Vth): -1V to -3V.
- This is the threshold voltage range of the channel MOSFET, which indicates the voltage that needs to be applied to the gate to make the device start to conduct. In this case, the threshold voltage range is -1V to -3V. .
