**Product parameter description**
- **Package type**: SOP8
The SOP8 package is suitable for surface mount (SMT) technology, with high integration and small size, suitable for space-constrained circuit design.
- **Configuration**: Dual N+P channels
This MOSFET is equipped with N-channel and P-channel MOSFETs, suitable for bipolar current flow, suitable for power management and bidirectional current switching scenarios.
- **V_DS (drain-source voltage)**: ±100V
The maximum drain-source voltage is ±100V, making this MOSFET suitable for a wide range of low-voltage applications, capable of withstanding bidirectional currents and controlling higher voltage differences.
- **V_GS (gate-source voltage)**: ±20V
The maximum gate-source voltage is ±20V, supporting standard gate drive voltages to ensure efficient drive and stable switching of MOSFETs.
- **V_th (gate threshold voltage)**: ±2V
The threshold voltage is ±2V, which allows the MOSFET to start conducting at a lower gate voltage and can cooperate with the control signal more flexibly.
- **R_DS(ON) (on resistance)**:
- **N channel**: 260mΩ (V_GS = 4.5V), 240mΩ (V_GS = 10V)
- **P channel**: 530mΩ (V_GS = 4.5V), 490mΩ (V_GS = 10V)
Low on resistance can significantly reduce power loss and improve power conversion efficiency.
- **I_D (Drain Current)**:
- **N-channel**: 2.2A
- **P-channel**: -1.9A
The maximum current carrying capability enables this MOSFET to carry medium power loads, making it very suitable for switch control and power management applications.
- **Technology Type**: Trench
Using Trench technology, it provides low on-resistance and high switching speed, ensuring efficient current transfer and low power loss.
