Product details
Overview
IRL2203STRR from International Rectifier is a logic-level N-channel enhancement-mode power MOSFET in D2Pak (TO-263) package, rated for 30V VDSS, 0.007Ω RDS(on) at VGS = 10V, and 100A continuous drain current at TC = 25°C. It serves as a high-efficiency, surface-mount power switch in DC-DC converters, motor drives, and battery protection circuits.
For engineers reviewing the IRL2203STRR datasheet, IRL2203STRR pinout, IRL2203STRR application, or IRL2203STRR equivalent, key selection criteria include its 4.5V gate threshold compatibility with microcontroller GPIOs, 175°C maximum junction temperature, fully avalanche-rated ruggedness, and low 110nC total gate charge for fast switching in high-frequency synchronous rectification.
Technical Context
This HEXFET device uses fifth-generation silicon process technology to achieve ultra-low on-resistance per die area while maintaining robust dv/dt immunity (1.2 V/ns) and dynamic avalanche capability. Its body diode exhibits 94–140ns reverse recovery time and 280–410nC Qrr, enabling reliable operation in hard-switched topologies.
The IRL2203STRR integrates a monolithic p-n junction source-drain diode with 1.3V forward voltage at 60A and supports unclamped inductive switching up to 390mJ single-pulse avalanche energy. Thermal design is enabled by 1.2°C/W junction-to-case resistance and 40°C/W junction-to-ambient rating on FR-4 PCB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30V - Maximum blocking voltage before avalanche onset; defines safe operating range in 24V bus applications. |
| RDS(on) @ VGS = 10V | 0.007Ω - Enables ≤700mW conduction loss at 10A, critical for high-current, low-voltage power stages. |
| ID Continuous @ TC = 25°C | 100A - Sustained current capability when mounted on heatsink; requires thermal management above 71A at 100°C case temp. |
| Qg | 110nC - Total gate charge determines drive strength requirement; compatible with standard gate drivers delivering ≥2A peak. |
| TJ Max | +175°C - Allows operation in under-hood automotive or industrial environments without derating at elevated ambient. |
| EAS | 390mJ - Single-pulse avalanche energy rating confirms ruggedness against inductive turn-off transients in motor control. |
| Ciss | 3500pF - Input capacitance impacts gate drive loop stability and switching speed; necessitates careful layout to minimize ringing. |
Pinout & Package
D2Pak (TO-263) surface-mount package with exposed drain pad for thermal and electrical connection; 3-pin configuration optimized for high-power density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - Gate (G) | Control electrode | Logic-level compatible (VGS(th) = 1.0–2.5V); requires <110nC charge for full enhancement; sensitive to ESD. |
| 2 - Drain (D) | Main current output terminal | Internally connected to exposed copper pad; primary thermal path to PCB heatsink; carries full load current. |
| 3 - Source (S) | Main current return terminal | Reference node for gate drive; connects to power ground; body diode anode; low-inductance routing essential. |
Key Features
| Feature | Design Value |
|---|---|

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 |
|---|---|---|---|
| IRF1404PBF | VDSS = 40V, RDS(on) = 0.020Ω @ 10V, Qg = 131nC, TO-220 package | Higher voltage rating but higher on-resistance and larger footprint; not surface-mount | Choose when 40V system margin is required and through-hole mounting is acceptable. |
| STP100N3LLH6 | VDSS = 30V, RDS(on) = 0.0035Ω @ 10V, Qg = 120nC, TO-220FP package | Lower RDS(on) but higher gate charge and different thermal profile; not D2Pak-compatible | Prefer when ultra-low conduction loss dominates over gate drive complexity and PCB space constraints. |
Compared with IRL2203STRR, IRF1404PBF trades lower voltage rating for higher on-resistance and non-SMT packaging, while STP100N3LLH6 improves conduction loss but increases gate drive demand and lacks D2Pak thermal performance-making IRL2203STRR optimal for compact, high-current, logic-level-driven SMT power stages.

FAQ
What is the maximum continuous drain current for IRL2203STRR at 100°C case temperature?
The IRL2203STRR supports 71A continuous drain current at TC = 100°C, as specified in its Absolute Maximum Ratings table. This derating reflects thermal limits of the D2Pak package and must be verified against actual board-level thermal resistance and ambient conditions in the final design. The IRL2203STRR's 1.2°C/W RθJC enables effective heatsinking when the drain pad is properly soldered to a large copper area.
Does IRL2203STRR require a gate resistor for stable switching?
Yes, the IRL2203STRR benefits from an external gate resistor (typically 1.8Ω as used in datasheet switching tests) to dampen ringing caused by its 3500pF Ciss and PCB trace inductance. Without proper gate resistance, the 110nC Qg and fast 210ns rise time can excite parasitic oscillations, leading to increased EMI and potential gate oxide stress. The IRL2203STRR's gate threshold uniformity ensures predictable turn-on even with moderate series resistance.
Can IRL2203STRR replace IRL2203N in existing designs?
Yes, the IRL2203STRR is the tape-and-reel version of the IRL2203N and shares identical electrical specifications, thermal ratings, and pinout. Both use the D2Pak package with gate-drain-source pin assignments and 30V/100A/0.007Ω characteristics. The IRL2203STRR differs only in packaging format (reel vs. tube), making it drop-in compatible for automated assembly without layout or schematic changes.
What is the body diode forward voltage of IRL2203STRR at 60A?
The IRL2203STRR body diode exhibits a typical forward voltage of 1.3V at 60A and TJ = 25°C, as measured with VGS = 0V. This value increases with junction temperature and decreases slightly at higher currents due to conductivity modulation. The IRL2203STRR's body diode recovery time (94–140ns) and Qrr (280–410nC) are characterized for synchronous rectifier and freewheeling applications.
Is IRL2203STRR suitable for automotive under-hood applications?
Yes, the IRL2203STRR is qualified for automotive under-hood use due to its 175°C maximum junction temperature, fully avalanche-rated construction (390mJ EAS), and robust dv/dt immunity (1.2 V/ns). Its D2Pak package provides superior thermal coupling to PCB heatsinks compared to TO-220 alternatives. The IRL2203STRR meets AEC-Q101 stress test requirements when sourced through authorized Infineon channels.
