Product details
Overview
IRF640NLPBF from Infineon Technologies (formerly International Rectifier) is a 200V, 18A N-channel enhancement-mode power MOSFET in TO-220AB package, featuring 0.15Ω RDS(on) at VGS = 10V, 150W power dissipation, and full avalanche rating. It serves as a high-efficiency switching element in DC-DC converters, motor drives, and AC solid-state relays.
For engineers reviewing the IRF640NLPBF datasheet, IRF640NLPBF pinout, IRF640NLPBF application, or IRF640NLPBF equivalent, key selection criteria include its 200V VDSS, 0.15Ω on-resistance, 67nC total gate charge, 167ns reverse recovery time, and TO-220AB thermal performance with RθJC = 1.0°C/W.
Technical Context
This HEXFET® fifth-generation MOSFET uses advanced silicon processing to minimize conduction loss while maintaining rugged fast-switching capability. Its gate threshold voltage (2.0–4.0V) enables direct TTL/CMOS drive, and the integrated body diode supports freewheeling in inductive loads.
The device is fully avalanche-rated (247mJ single-pulse EAS), supports high dv/dt (8.1V/ns), and exhibits low output capacitance (Coss = 185pF at VDS = 25V), enabling stable operation in hard-switched topologies up to 100kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 200V - maximum blocking voltage before avalanche; suitable for 120VAC line-fed SMPS and 48V industrial bus systems |
| RDS(on) | 0.15Ω @ VGS=10V, ID=11A - enables <1.8W conduction loss at 11A, reducing heatsink requirements |
| ID (TC=25°C) | 18A - continuous drain current rating under ideal heatsinking; derates linearly above 25°C case temperature |
| Qg | 67nC - total gate charge determines driver strength needed; requires ≥1A peak gate current for 100ns switching transitions |
| trr | 167ns (typ) - body diode reverse recovery time impacts turn-on loss in synchronous rectification and half-bridge freewheeling |
| EAS | 247mJ - single-pulse avalanche energy rating allows safe operation during inductive load switching transients without snubbers |
| RθJC | 1.0°C/W - junction-to-case thermal resistance enables 150W dissipation with ≤150°C temperature rise across heatsink interface |
Pinout & Package
IRF640NLPBF is housed in a through-hole TO-220AB package with isolated tab (drain-connected), standard mounting hole, and 1.1N·m screw torque rating. The package provides low thermal resistance and mechanical robustness for industrial power stages.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (Tab) | Main current path from source to load return | Electrically connected to metal tab; must be electrically isolated from heatsink unless circuit design intentionally ties drain to chassis ground |
| Gate | Control terminal for channel modulation | High-impedance input requiring <100nA leakage; sensitive to ESD; driven by logic-level or dedicated gate driver |
| Source | Reference node for gate drive and current return | Common connection point for load return, gate driver reference, and current sensing; defines local ground potential |
Key Features
| Feature | Design Value |
|---|---|
| Fully avalanche rated | 247mJ single-pulse EAS ensures reliable operation during inductive switching faults without external protection |
| Low RDS(on) | 0.15Ω minimizes I²R conduction loss in high-current DC-DC and motor control applications |
| Fast body diode | 167ns trr and 929nC Qrr reduce switching loss in freewheeling paths and synchronous rectifiers |
| Simple gate drive | 2.0–4.0V VGS(th) allows direct interface with 3.3V/5V microcontrollers and logic buffers without level-shifting |
| Thermally optimized package | TO-220AB delivers 1.0°C/W RθJC, supporting 150W operation with standard heatsinks and thermal paste |
Applications
| Switch-Mode Power Supply | Motor Drive Stage |
|---|---|
Use Scenario: Primary-side switch in 100–500W offline flyback or forward converters. IC Role / Device Role / Timing Role: High-voltage switching element controlling energy transfer from AC line to transformer primary. Use Value: 200V VDSS accommodates reflected flyback spikes up to 170V; 0.15Ω RDS(on) keeps conduction loss below 3% at full load. | Use Scenario: Half-bridge high-side switch in 24–48V brushed DC motor controllers. IC Role / Device Role / Timing Role: Power switch delivering PWM-controlled current to motor windings. Use Value: Avalanche rating absorbs inductive kickback during PWM off-time; 18A ID supports 300W continuous motor output. |
| AC Solid-State Relay | DC Load Switch |
Use Scenario: Bidirectional AC switching in programmable logic controller (PLC) output modules. IC Role / Device Role / Timing Role: Back-to-back configured MOSFET providing zero-crossing–free AC load control. Use Value: 200V blocking capability covers 120/230VAC RMS; low gate charge enables fast turn-on for precise timing control. | Use Scenario: High-side power switch for 12–24V automotive or industrial auxiliary loads. IC Role / Device Role / Timing Role: Load disconnect and overcurrent protection switch in battery management subsystems. Use Value: 150W PD rating supports 10A@12V continuous loads; built-in avalanche tolerance prevents failure during cable short events. |
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 |
|---|---|---|---|
| STP20NM60FD | 600V VDSS, 0.27Ω RDS(on), D2PAK package | Higher voltage rating but higher on-resistance and surface-mount only | Select when 600V blocking is required and PCB layout supports SMT; not drop-in for TO-220 footprint |
| IXTP18N20P | 200V VDSS, 0.16Ω RDS(on), TO-220FP (full-pack) package | Same voltage/current specs but lower profile and no isolated tab | Choose for space-constrained designs where tab isolation is unnecessary and lower height is critical |
Compared with STP20NM60FD and IXTP18N20P, IRF640NLPBF offers the lowest RDS(on) in TO-220AB with isolated drain tab-ideal for thermally demanding through-hole power stages where heatsink isolation is mandatory.

FAQ
Is IRF640NLPBF lead-free and RoHS compliant?
Yes. The "PbF" suffix confirms compliance with RoHS Directive 2011/65/EU. The device uses lead-free terminations and meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1), allowing unlimited floor life at ≤30°C/60% RH.
Can IRF640NLPBF be used with 3.3V microcontroller GPIOs?
No. With a minimum VGS(th) of 2.0V and typical RDS(on) specified at VGS = 10V, 3.3V drive yields high on-resistance (>1Ω) and excessive heating. A gate driver or level shifter is required for reliable switching.
What is the maximum recommended case temperature for continuous operation?
The absolute maximum case temperature is 175°C, but continuous operation above 100°C requires derating per the linear derating factor of 1.0W/°C. At TC = 100°C, maximum allowable power dissipation drops to 75W to maintain safe junction temperature.
Does IRF640NLPBF require a gate resistor, and what value is typical?
Yes. A gate resistor limits peak current during switching and damps ringing. For 100kHz operation with a 1A driver, a 10Ω series resistor is typical-balancing switching speed (≈20ns rise/fall) against EMI and gate oscillation risk.
