Product details
Overview
IRF640NL from Infineon Technologies (formerly International Rectifier) is a 200V, 18A N-channel enhancement-mode power MOSFET in TO-220AB package with 0.15Ω RDS(on) at VGS = 10V, fully avalanche-rated, and optimized for hard-switched DC-DC converters, motor drives, and UPS inverters.
For engineers reviewing the IRF640NL datasheet, IRF640NL pinout, IRF640NL application, or IRF640NL equivalent, key selection criteria include its 247mJ single-pulse avalanche energy, 8.1V/ns di/dt-rated body diode recovery, 175°C maximum junction temperature, and through-hole low-profile mounting capability.
Technical Context
This fifth-generation HEXFET® device uses advanced silicon processing to achieve low on-resistance per die area while maintaining rugged unclamped inductive switching performance. Its gate threshold voltage (2.0–4.0V) and 67nC total gate charge support standard logic-level drive with moderate speed control.
The integrated body diode exhibits 167–251ns reverse recovery time and 929–1394nC Qrr under 100A/µs di/dt, enabling reliable operation in freewheeling and synchronous rectification roles where fast, predictable diode turn-off is required.
Key Specifications

|---|---|
| VDSS | 200V - supports 150V bus designs with 33% safety margin against transients |
| RDS(on) | 0.15Ω max @ VGS=10V - delivers ≤3.0W conduction loss at 11A continuous drain current |
| ID @ TC=25°C | 18A - enables high-current switching in compact heatsinked layouts |
| EAS | 247mJ - withstands single-event inductive energy spikes without failure |
| dv/dt Rating | 8.1V/ns - ensures robustness against rapid voltage transients during commutation |
| TJ Range | −55°C to +175°C - certified for industrial and automotive under-hood environments |
| Qg | 67nC - determines gate driver power requirement and switching transition time |
Pinout & Package
IRF640NL uses the industry-standard TO-220AB through-hole package with isolated tab (drain-connected), rated for 150W dissipation at 25°C case temperature and 1.0°C/W junction-to-case thermal resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - Gate | Control electrode | Receives 10V logic-level drive; 67nC total charge requires ≥1A peak gate driver for <100ns switching |
| 2 - Drain | Main current output | Connected to heatsink via isolated tab; handles full load current and avalanche energy return path |
| 3 - Source | Reference node | Serves as power ground reference; internal source inductance (7.5nH) affects high-di/dt ringing |
| 4 - Drain (Tab) | Thermal & electrical connection | Electrically tied to pin 2; provides primary heat transfer path to external heatsink |
Key Features
| Feature | Design Value |
|---|---|
| Fully avalanche-rated | 247mJ single-pulse energy rating eliminates need for external snubbers in inductive loads |
| Dynamic dv/dt tolerance | 8.1V/ns rating prevents false turn-on during high-speed voltage transitions |
| 175°C operating junction | Enables derated operation in sealed enclosures or high-ambient industrial settings |
| Low RDS(on) × Qg figure-of-merit | 10.05Ω·nC - balances conduction efficiency and switching loss in 20–100kHz applications |
| Simple drive requirements | Threshold voltage range (2.0–4.0V) allows compatibility with 3.3V/5V/12V controllers without level-shifting |

FAQ
What is the maximum continuous drain current for IRF640NL at 100°C case temperature?
The maximum continuous drain current is 13A at TC = 100°C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the TO-220AB package and must be applied when heatsink temperature exceeds 25°C. Designers should verify junction temperature using RθJC = 1.0°C/W and ambient conditions to ensure safe operation below 175°C.
Does IRF640NL have a built-in body diode, and what are its key recovery characteristics?
Yes, IRF640NL integrates a monolithic p-n junction body diode with typical reverse recovery time of 167ns and maximum of 251ns at TJ = 25°C, IF = 11A, and di/dt = 100A/µs. Its Qrr ranges from 929nC to 1394nC, and it supports peak diode recovery dv/dt up to 8.1V/ns - critical for minimizing switching losses in freewheeling paths.
Can IRF640NL be used in parallel configurations, and what design considerations apply?
Yes, IRF640NL is explicitly designed for easy paralleling due to its positive temperature coefficient of RDS(on), which promotes current sharing. Key considerations include matched gate drive impedance (<2.5Ω), symmetrical PCB layout to minimize loop inductance, and individual gate resistors to damp oscillation. Thermal coupling between devices must also be managed to avoid localized hot spots.
What is the gate threshold voltage range, and how does it affect drive circuit design?
The gate threshold voltage (VGS(th)) is specified from 2.0V to 4.0V at ID = 250µA. This wide range means full enhancement requires ≥10V VGS to guarantee 0.15Ω RDS(on). Drive circuits must deliver sufficient voltage and peak current (≥1A) to charge 67nC gate capacitance quickly, especially given the device's 33nC Miller charge that dominates turn-off delay.
