ELM13400CA-VB is a VBsemi brand SOT23-3 packaged N-channel field effect transistor. The following is a detailed parameter description and application introduction of the device:

- **Parameter Description:**
- Package: SOT23-3
- Channel type: N-channel
- Rated voltage: 30V
- Maximum current: 6.5A
- Switch resistance: RDS(ON)=30mΩ@VGS=10V, VGS=20V
- Threshold voltage: Vth=1.2~2.2V

- **Application Introduction:**
ELM13400CA-VB is suitable for a variety of electronic applications, especially in low voltage and high switching frequency environments. Common application areas include but are not limited to:
- Power management modules
- DC-DC converters
- Current control modules
- Inverters
- Motor drives

The high current and low switching resistance of the device make it particularly useful in scenarios that require efficient energy conversion. At the same time, its SOT23-3 package makes it suitable for board designs with limited space.
