Key Parameters and Selection Guide
| Parameter | Value | Significance |
|---|---|---|
| RDS(on) | 380mΩ | Reduces power loss in switching applications |
| Gate Charge (Qg) | Not specified | Lower values improve high-frequency performance |
| Power Dissipation | 100mW | Critical for thermal management in compact designs |
Selection Tips:
Choose for applications under 20V where board space is limited (e.g., wearables).
Prioritize this model when low VGS(th) (350mV) is needed for battery-powered systems.
Consider thermal dissipation – use PCB copper pads for heat sinking.
Application Examples
Portable Electronics: Power switches in smartphones (MCC cites 60% smaller footprint than SOT-23).
IoT Sensors: Energy harvesting circuits due to low leakage current.
Automotive: LED drivers in dashboard lighting (operates up to 150°C).
