Product details
Overview
IRL2505STRL from Infineon Technologies (formerly International Rectifier) is a 55 V, 110 A, 0.008 Ω RDS(on) N-channel HEXFET® Power MOSFET in TO-262 (DPAK) package, optimized for high-current DC-DC conversion, motor control, and battery protection circuits operating at 10 V gate drive.
For engineers reviewing the IRL2505STRL datasheet, IRL2505STRL pinout, IRL2505STRL application, or IRL2505STRL equivalent, this part supports high-pulse-current switching up to 110 A with low conduction loss, fast 40 ns turn-on delay, and robust avalanche energy rating of 190 mJ - critical for automotive body electronics and industrial power supplies.
Technical Context
This logic-level MOSFET features a planar stripe cell structure enabling low on-resistance at VGS = 10 V and stable operation up to TJ = 175 °C. Its gate charge profile (QG = 71 nC, QGD = 28 nC) supports efficient PWM switching at frequencies up to 100 kHz in synchronous buck converters.
The device integrates an intrinsic body diode with trr = 110 ns and QRR = 120 nC under IF = 54 A, VDD = 44 V conditions, making it suitable for freewheeling and reverse recovery–sensitive topologies like half-bridge inverters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 55 V - Maximum drain-source blocking voltage; defines safe operating range in 48 V battery systems. |
| RDS(on) @ VGS = 10 V | 0.008 Ω - Enables ≤0.97 W conduction loss at 110 A; reduces heatsink requirements in high-current PCB layouts. |
| ID (continuous) | 110 A - Rated continuous drain current at TC = 25 °C; derates to 70 A at TC = 100 °C per thermal resistance curve. |
| QG | 71 nC - Total gate charge; determines driver strength needed for <1 µs switching transitions at 12 V gate drive. |
| EAS | 190 mJ - Single-pulse avalanche energy at TJ = 25 °C; provides margin against inductive switching transients in motor drives. |
| td(on) | 40 ns - Turn-on delay time; enables precise timing control in high-frequency synchronous rectification. |
| Ciss | 2200 pF - Input capacitance at VDS = 25 V; impacts gate driver power dissipation and EMI filtering design. |
Pinout & Package
IRL2505STRL uses the TO-262 (DPAK) surface-mount package with exposed drain pad for thermal enhancement. The three-terminal configuration supports high-current PCB mounting with minimal trace inductance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (Tab) | Main current path output | Internally connected to metal tab; must be soldered to large copper pour for thermal management and low-inductance return path. |
| Source | Reference node for gate drive and current sensing | Low-impedance source terminal; used for Kelvin sensing in precision current monitoring applications. |
| Gate | Control input for channel conduction | Logic-compatible threshold (VGS(th) = 2.0 V typ); requires <100 Ω series resistor to suppress ringing during fast switching. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RDS(on) at 10 V drive | 0.008 Ω enables <1 W conduction loss at 110 A - reduces thermal stress in compact power modules. |
| 175 °C maximum junction temperature | Rated for sustained operation in engine bay or industrial enclosures without forced air cooling. |
| 100% avalanche rated | Guaranteed single-pulse EAS = 190 mJ supports reliable operation in inductive load switching without external snubbers. |
| Fast body diode recovery | trr = 110 ns and QRR = 120 nC minimize switching losses and voltage overshoot in freewheeling paths. |
| Lead-free and RoHS compliant | Meets IPC-J-STD-020 moisture sensitivity level 1; suitable for lead-free reflow assembly without pre-baking. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRF1405PBF | RDS(on) = 0.0055 Ω @ 10 V, but higher QG = 130 nC and larger TO-220 package. | Better conduction loss but slower switching; less suitable for high-frequency SMPS. | Prefer when thermal budget allows larger heatsink and switching frequency <50 kHz. |
| STP110N55F6 | RDS(on) = 0.0075 Ω @ 10 V, lower Ciss = 1700 pF, but only rated to 175 °C with 100 A ID. | Improved EMI performance due to lower input capacitance; slightly lower current headroom. | Choose for space-constrained designs needing faster gate drive response and tighter layout control. |
Compared with IRL2505STRL, IRF1405PBF offers lower on-resistance but demands stronger gate drivers and more board area, while STP110N55F6 trades minor RDS(on) improvement for better high-frequency behavior and tighter thermal margins at full current.

FAQ
What is the maximum continuous drain current for IRL2505STRL at 100 °C case temperature?
At TC = 100 °C, the maximum continuous drain current is 70 A. This value is derived from the device's thermal resistance (RθJC = 1.0 °C/W) and maximum junction temperature (175 °C), ensuring safe operation without exceeding thermal limits under steady-state conditions.
Does IRL2505STRL require a gate driver IC for 100 kHz PWM operation?
Yes - driving the 71 nC gate charge at 100 kHz requires ≥7.1 mA average gate current. A dedicated gate driver (e.g., IR2110 or TC4427) is recommended to ensure clean 40 ns turn-on and prevent shoot-through in bridge configurations.
Can IRL2505STRL replace IRL2505PbF in existing designs?
Yes - IRL2505STRL and IRL2505PbF share identical electrical specifications, pinout, and TO-262 package. The "TRL" suffix denotes tape-and-reel packaging; no layout or thermal redesign is needed for drop-in substitution.
Is the body diode in IRL2505STRL suitable for synchronous rectification?
No - while the body diode is fully rated and avalanche-robust, its 110 ns reverse recovery time and 120 nC QRR make it unsuitable for high-efficiency synchronous rectification above 50 kHz; an external Schottky or GaN FET is preferred for that function.
