IRL2505STRLPBF

IRL2505STRLPBF Description

The IRL2505STRLPBF from Infineon Technologies is a high-performance N-channel HEXFET® power MOSFET designed for demanding switching applications. With a 55V drain-to-source voltage (Vdss) and continuous drain current (Id) of 104A (Tc), this device delivers robust power handling in a compact D2PAK (TO-263) surface-mount package. It features an ultra-low on-resistance (Rds(on)) of 8mΩ at 10V gate drive, minimizing conduction losses and improving efficiency. Although marked as Obsolete, its specifications remain competitive for legacy designs or replacements. The MOSFET operates with a gate threshold voltage (Vgs(th)) of 2V max, making it compatible with low-voltage drive circuits.

IRL2505STRLPBF Features

• Low Rds(on): 8mΩ @ 54A, 10V ensures reduced power dissipation.
• High Current Capability: 104A (Tc) continuous drain current for high-power applications.
• Optimized Gate Charge: 130nC @ 5V (Qg) balances switching speed and losses.
• Wide Vgs Range: ±16V maximum gate-source voltage for flexibility in drive circuits.
• Thermal Performance: 200W (Tc) power dissipation with proper heatsinking.
• Robust Packaging: D2PAK (TO-263) offers mechanical durability and efficient thermal transfer.
• Compliance: ROHS3 and REACH unaffected, suitable for environmentally conscious designs.
