IRF5210L

IRF5210L Description

The IRF5210L from Infineon Technologies is a high-performance P-channel HEXFET® MOSFET designed for power management applications. With a drain-to-source voltage (Vdss) rating of 100V and a continuous drain current (Id) of 40A (at Tc), this MOSFET is optimized for high-efficiency switching and linear amplification. It features a low on-resistance (Rds(on)) of just 60mΩ at 10V gate drive, ensuring minimal conduction losses. The device is housed in a TO-262 (D²PAK) package, making it suitable for through-hole mounting in power electronics designs.

IRF5210L Features

• High Voltage & Current Handling: Supports 100V Vdss and 40A Id, ideal for robust power applications.
• Low Rds(on): 60mΩ @ 10V Vgs reduces power dissipation and improves efficiency.
• Fast Switching: Gate charge (Qg) of 180nC @ 10V and input capacitance (Ciss) of 2700pF @ 25V ensure quick turn-on/off transitions.
• Wide Gate-Source Voltage Range: ±20V Vgs(max) offers flexibility in drive circuitry.
• Thermal Performance: 200W power dissipation (Tc) and 3.8W (Ta) enable reliable operation under high loads.
• Obsolete Status: While no longer in production, it remains a reliable choice for legacy designs.
