Manufacturer: Infineon Technologies

Categories: Single FETs, MOSFETs

Quality Control: Learn More

Infineon Technologies P-Channel HEXFET® MOSFET, part number SI3443DVTRPBF, is a surface-mount device designed for high-efficiency power management applications. This component features a drain-source voltage (Vdss) of 20V and a continuous drain current (Id) of 4.4A at 25°C. The Rds(On) is specified at a maximum of 65mOhm at 4.4A drain current and 4.5V gate-source voltage. With a gate charge (Qg) of 15 nC at 4.5V, it offers optimized switching performance. The device is housed in a Micro6™ (TSOP-6) package, facilitating compact board layouts. Operating across a temperature range of -55°C to 150°C (TJ), it is suitable for use in automotive and industrial electronics. This MOSFET supports a gate-source voltage (Vgs) range of ±12V and has a threshold voltage (Vgs(th)) of 1.2V maximum at 250µA. Its maximum power dissipation is 2W.
