IRLIB9343PBF

IRLIB9343PBF Description

The IRLIB9343PBF from Infineon Technologies is a P-channel HEXFET® power MOSFET designed for high-efficiency switching applications. With a drain-to-source voltage (Vdss) of 55V and a continuous drain current (Id) of 14A (at Tc=25°C), this device is optimized for power management in medium-voltage circuits. It features a low on-resistance (Rds(on)) of 105mΩ at 10V gate drive, ensuring minimal conduction losses. The MOSFET is housed in a TO-220AB FP package, offering robust thermal performance with a maximum power dissipation of 33W (Tc).

IRLIB9343PBF Features

• Low Gate Charge (Qg): 47nC at 10V reduces switching losses, enhancing efficiency in high-frequency applications.
• Wide Gate-Source Voltage Range (Vgs): ±20V provides flexibility in drive circuit design.
• Low Input Capacitance (Ciss): 660pF at 50V minimizes gate drive requirements.
• Fast Switching Performance: Optimized for applications requiring rapid turn-on/off.
• Reliable Construction: ROHS3 compliant and REACH unaffected, ensuring environmental and regulatory compliance.
• High Thermal Stability: MSL 1 (Unlimited) rating guarantees long-term reliability in harsh conditions.
