HM3413-VB is a P-Channel field effect transistor of VBsemi brand. The specific parameters are as follows:
- Package: SOT23
- Maximum operating voltage: -20V
- Maximum current: -4A
- RDS(ON): 57mΩ @ VGS=4.5V, VGS=12V
- Threshold voltage: Vth=-0.81V

**Application introduction:**
Suitable for circuits and modules that require P-Channel MOSFET, especially in situations where lower impedance and smaller threshold voltage are required.

**Example application:**
1. **Power management module:** Due to low impedance and moderate current capacity, it is suitable for power switch and regulation modules.

2. **Motor drive:** In situations where reverse control is required, such as DC motor drive module.

3. **Battery protection circuit:** Due to the low threshold voltage and small size of the SOT23 package, it is suitable for battery protection circuits to ensure that the battery is cut off in a low voltage state.

Please note that the specific application needs to be verified based on the electrical requirements and design parameters of the project.
