IRL2505S

IRL2505S Description

The IRL2505S from Infineon Technologies is a high-performance N-channel HEXFET® MOSFET designed for power-switching applications. With a 55V drain-to-source voltage (Vdss) and continuous drain current (Id) of 104A (Tc), it delivers robust power handling in a compact D2PAK (TO-263) surface-mount package. This obsolete model remains relevant for legacy designs, offering low on-resistance (Rds(on)) of 8mOhm at 10V Vgs, ensuring efficient power conversion with minimal losses. Its ±16V gate-to-source voltage (Vgs) tolerance and 4V/10V drive voltage compatibility make it versatile for both logic-level and standard gate drives.

IRL2505S Features

• Low Rds(on): 8mOhm @ 54A, 10V reduces conduction losses.
• High Current Capability: 104A (Tc) continuous drain current for demanding loads.
• Fast Switching: Optimized gate charge (Qg = 130nC @ 5V) and input capacitance (Ciss = 5000pF @ 25V) balance speed and efficiency.
• Robust Thermal Performance: Dissipates up to 200W (Tc) with proper heatsinking.
• Wide Vgs Range: ±16V tolerance enhances design flexibility.
• Industry-Standard Package: D2PAK (TO-263) for easy integration into power PCB layouts.

IRL2505S Applications

• Power Supplies: High-efficiency DC-DC converters and SMPS due to low Rds(on).
• Motor Drives: Ideal for H-bridge configurations in industrial or automotive systems.
• Load Switching: Suited for high-current relays, solenoids, or battery management.
• Audio Amplifiers: Low-distortion switching in Class-D designs.
• Legacy Systems: Reliable replacement for obsolete designs requiring D2PAK packaging.

Conclusion of IRL2505S

The IRL2505S excels in high-current, low-loss applications, leveraging Infineon’s HEXFET® technology for superior thermal and electrical performance. While marked obsolete, its combination of low Rds(on), high current rating, and D2PAK form factor makes it a pragmatic choice for engineers maintaining or upgrading existing systems. For new designs, consider modern alternatives, but the IRL2505S remains a proven solution for rugged power management.
