IRF3805STRL-7PP

IRF3805STRL-7PP Description

The IRF3805STRL-7PP from Infineon Technologies is a high-performance N-channel MOSFET designed for power management applications requiring robust efficiency and thermal stability. Part of the HEXFET® series, this surface-mount device features a 55V drain-to-source voltage (Vdss) and a continuous drain current (Id) of 160A (Tc), making it suitable for high-current switching. With an ultra-low on-resistance (Rds(on)) of 2.6mΩ at 140A, 10V, it minimizes conduction losses, enhancing energy efficiency in demanding circuits. Packaged in D2PAK (TO-263) and supplied in Tape & Reel (TR), it is optimized for automated assembly.

IRF3805STRL-7PP Features

• Low Rds(on): 2.6mΩ @ 10V Vgs ensures reduced power dissipation.
• High Current Handling: 160A continuous drain current (Tc) for heavy-load applications.
• Fast Switching: Gate charge (Qg) of 200nC @ 10V and input capacitance (Ciss) of 7820pF @ 25V enable efficient high-frequency operation.
• Robust Construction: ±20V gate-to-source voltage (Vgs) tolerance and 300W (Tc) power dissipation capability.
• Compliance: ROHS3 and REACH compliant, with ECCN EAR99 for global usability.
• Thermal Performance: MSL 1 (Unlimited) rating ensures reliability in humid environments.

IRF3805STRL-7PP Applications

Ideal for high-efficiency power systems, the IRF3805STRL-7PP excels in:
