Product details
Overview
IRL2203NSTRR from Infineon Technologies (formerly International Rectifier) is a 30V, 116A N-channel enhancement-mode power MOSFET in D2PAK (TO-262) package, featuring 7.0mΩ RDS(on) at VGS = 10V, 100% RG tested, and fully avalanche rated for robust high-current switching in DC-DC converters and motor drives.
For engineers reviewing the IRL2203NSTRR datasheet, IRL2203NSTRR pinout, IRL2203NSTRR application, or IRL2203NSTRR equivalent, key selection criteria include its 7.0mΩ on-resistance at 10V gate drive, 175°C maximum junction temperature, 60nC total gate charge, fast 160ns rise time, and D2PAK thermal performance with 0.85°C/W RθJC.
Technical Context
This MOSFET employs advanced HEXFET® process technology to achieve ultra-low conduction loss while maintaining rugged unclamped inductive switching capability. Its intrinsic body diode supports synchronous rectification with 56–84ns reverse recovery time and 110–170nC Qrr, enabling efficient operation in hard-switched topologies.
The device is characterized for continuous drain current up to 116A at TC = 25°C and derates linearly above 25°C with 1.2W/°C slope. It sustains repetitive avalanche energy of 1320mJ (typ.) and single-pulse EAS up to 290mJ under defined test conditions (IAS = 60A, L = 0.16mH).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30V - Maximum blocking voltage before avalanche onset; defines safe operating range in 24V bus systems. |
| RDS(on) | 7.0mΩ @ VGS = 10V - Enables <1.2W conduction loss at 40A, critical for high-efficiency 12–24V power stages. |
| ID (TC = 25°C) | 116A - Continuous current rating limited by package thermal resistance, not silicon area. |
| Qg | 60nC - Total gate charge determines driver strength requirement; impacts switching loss in 100kHz–500kHz designs. |
| tr/tf | 160ns/66ns - Fast edge rates reduce transition losses but require careful PCB layout to suppress ringing. |
| TJ max | 175°C - Allows operation in sealed enclosures or high-ambient industrial environments without forced cooling. |
| EAS | 290mJ - Single-pulse avalanche energy rating validates reliability during load dump or inductive turn-off events. |
Pinout & Package
D2PAK (TO-262) surface-mount package with exposed drain pad for low thermal resistance (RθJC = 0.85°C/W) and high-power dissipation (up to 95W with heatsink). Three-terminal configuration optimized for high-current PCB routing and thermal management.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (Tab) | Main current path output / heat sink interface | Electrically and thermally connected to exposed copper pad; must be soldered to large copper pour or heatsink. |
| Source | Reference node for gate drive and current sensing | Low-inductance connection essential for stable gate control and accurate shunt-based current monitoring. |
| Gate | Control input for channel conduction | High-impedance terminal requiring <3.0Ω series resistance to damp oscillation; sensitive to ESD. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RDS(on) | 7.0mΩ enables >97% efficiency in 48V→12V buck converters at 50A output. |
| Fully avalanche rated | Guarantees survivability under unclamped inductive switching without derating design margins. |
| 100% RG tested | Ensures consistent gate drive timing and eliminates batch-to-batch variation in switching behavior. |
| Lead-free (PbF) construction | Complies with RoHS Directive 2011/65/EU and JEDEC J-STD-020 reflow profile requirements. |
| Dynamic dv/dt rated | Withstands 110A/µs di/dt and >10V/ns dv/dt during commutation without false turn-on. |

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 |
|---|---|---|---|
| IRF1404ZPBF | 40V VDSS, 184A ID, 4.7mΩ RDS(on), TO-220 package | Higher voltage margin but larger footprint and higher RθJA; unsuitable for space-constrained D2PAK layouts. | Select when 40V blocking is required and through-hole mounting is acceptable. |
| STP120N3LLH6 | 30V VDSS, 120A ID, 5.2mΩ RDS(on), TO-220FP package | Lower RDS(on) but 1.2W/°C derating and no avalanche rating; requires external snubbing in inductive loads. | Select only in non-avalanche-critical applications with active thermal management. |
Compared with IRL2203NSTRR, IRF1404ZPBF offers higher voltage headroom at the cost of thermal performance and board area, while STP120N3LLH6 improves conduction loss but sacrifices ruggedness-making IRL2203NSTRR the optimal balance of avalanche safety, thermal efficiency, and surface-mount compatibility for 24V industrial systems.

FAQ
What is the maximum continuous drain current for IRL2203NSTRR at 100°C case temperature?
The datasheet specifies 82A continuous drain current at TC = 100°C and VGS = 10V. This reflects linear derating from 116A at 25°C using the 1.2W/°C slope and thermal limits of the D2PAK package-not silicon-limited conduction. Operation above this requires active cooling or reduced duty cycle.
Does IRL2203NSTRR have a built-in body diode, and what are its key parameters?
Yes, it integrates a monolithic p-n body diode with 1.2V forward voltage at 60A, 56–84ns reverse recovery time, and 110–170nC reverse recovery charge. These values are measured at TJ = 25°C, IF = 60A, and VGS = 0V, making it suitable for synchronous rectification in buck converters up to 500kHz.
Can IRL2203NSTRR be used in avalanche mode repeatedly, and what is the limit?
It is fully rated for repetitive avalanche operation with EAR = 1320mJ (typ.) per pulse. The datasheet confirms this is a repetitive rating-not single-event only-with pulse width limited by junction temperature. Safe operation requires limiting cumulative avalanche energy to avoid exceeding 175°C TJ under worst-case transient conditions.
What is the recommended gate resistor value for driving IRL2203NSTRR in a 200kHz buck converter?
A 1.8Ω gate resistor is validated in the datasheet for 60A switching with VDD = 15V and RG = 1.8Ω, yielding ~160ns rise time. For 200kHz operation, this value balances switching loss reduction against gate drive power and EMI; lower values (<1Ω) increase shoot-through risk, while higher values (>5Ω) raise tr/tf and conduction loss.
