Product details

Overview

IRFL1006PBF from International Rectifier is a 60V, 1.6A N-channel enhancement-mode Power MOSFET in SOT-223 package, featuring R_DS(on) = 0.22Ω at V_GS = 10V, fully avalanche-rated, and optimized for surface-mount DC-DC converters, load switches, and low-power motor drives.

For engineers reviewing the IRFL1006PBF datasheet, IRFL1006PBF pinout, IRFL1006PBF application, or IRFL1006PBF equivalent, key selection criteria include its 60V V_DS, 0.22Ω on-resistance, 1.0W PCB-mounted power dissipation, fast 7.4ns turn-on delay, and SOT-223 thermal performance with enlarged heatsink tab.

Technical Context

This fifth-generation HEXFET uses advanced silicon processing to minimize R_DS(on) per die area while maintaining rugged unclamped inductive switching capability (E_AS = 54mJ). Its gate threshold voltage (2.0–4.0V) supports standard 5V/10V logic-level drive without requiring dedicated level shifters.

The device integrates a fast-recovery body diode (t_rr = 31–47ns, Q_rr = 46–68nC) and exhibits low output capacitance (C_oss = 55pF at V_DS = 25V), enabling high-frequency switching in compact power stages where dv/dt immunity (5.0V/ns) and thermal stability (T_J = –55°C to +150°C) are critical.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60V - maximum blocking voltage for 48V rail applications with margin
R_DS(on)	0.22Ω @ V_GS = 10V - enables <1.6A continuous conduction with ≤0.56W I²R loss
I_D (continuous)	1.6A @ T_A = 25°C - usable up to 1.3A at 70°C ambient in typical PCB layout
P_D (PCB mount)	1.0W - achievable with minimum FR-4 footprint; 2.1W possible on 1"² copper
t_r/t_f	18ns/17ns - supports >1MHz switching in buck regulators with low gate charge (Q_g = 8.0nC)
E_AS	54mJ - single-pulse avalanche energy rating ensures robustness during inductive turn-off transients
dv/dt rating	5.0V/ns - suppresses false turn-on in noisy high-dv/dt environments like motor commutation

Pinout & Package

SOT-223 (TO-261AA) surface-mount package with exposed drain tab for direct PCB heatsinking; compatible with vapor-phase, infrared, and wave soldering. Pin 1 = Gate, Pin 2 = Drain (tab), Pin 3 = Source, Pin 4 = Source (redundant).

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (G)	Gate	Control terminal; requires ≤±20V drive; 100nA leakage at ±20V ensures low standby current
Pin 2 (D)	Drain	Main power terminal; electrically connected to exposed copper tab for thermal conduction and current return path
Pins 3 & 4 (S)	Source	Power reference node; dual-source pins reduce bondwire inductance and improve current sharing in pulsed operation

Key Features

Feature	Design Value
Fully avalanche-rated	Guarantees safe operation under unclamped inductive switching (IAS = 1.6A, EAS = 54mJ) without derating
Lead-free SOT-223	RoHS-compliant packaging with enhanced thermal pad; 50°C/W θ_JA on 1"² copper vs. 90°C/W on FR-4
Fast body diode	31ns reverse recovery time and 46nC Q_rr reduce switching losses in synchronous rectification and H-bridge freewheeling
Logic-level compatible	V_GS(th) range (2.0–4.0V) allows direct drive from 3.3V/5V microcontrollers without gate driver ICs
Low gate charge	Q_g = 8.0nC minimizes driver power consumption and enables efficient 1MHz+ PWM control

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
DMN2004LK-7	R_DS(on) = 0.18Ω @ V_GS = 4.5V; SOT-23 package; lower ID (1.2A)	Better for 3.3V logic drive but limited to ≤1.2A continuous; less thermal mass than SOT-223	Select when board space is constrained and gate drive is sub-5V; avoid for >1A sustained loads.
SI2306DS-T1-GE3	R_DS(on) = 0.045Ω @ V_GS = 4.5V; SOT-23; higher ID (3.4A); no avalanche rating	Superior conduction efficiency at low V_GS, but lacks E_AS protection for inductive loads	Prefer for battery-powered 3.3V systems with resistive loads; not recommended for motor or relay switching.

Compared with DMN2004LK-7 and SI2306DS-T1-GE3, IRFL1006PBF trades slightly higher R_DS(on) for full avalanche ruggedness, SOT-223 thermal capability, and proven reliability in industrial 24–48V power stages where transient robustness outweighs marginal conduction loss.

FAQ

What is the maximum continuous drain current at 70°C ambient?

The IRFL1006PBF supports 1.3A continuous drain current at T_A = 70°C with V_GS = 10V, based on linear derating from 1.6A at 25°C using the 8.3mW/°C factor and standard FR-4 mounting. This assumes adequate PCB copper area and no forced airflow.

Is IRFL1006PBF suitable for 3.3V microcontroller gate drive?

Yes-its gate threshold voltage range (2.0–4.0V) ensures reliable turn-on with 3.3V logic, though R_DS(on) increases to ~0.35Ω at V_GS = 4.5V. For minimal on-resistance, use 5V or 10V drive; for 3.3V systems, verify load current stays below 1A to limit conduction loss.

Does the SOT-223 package require special PCB layout considerations?

Yes-the exposed drain tab must be connected to a large copper pour (≥1"² recommended) for thermal performance. Minimum FR-4 footprint yields θ_JA = 90°C/W; doubling copper area reduces it to ~50°C/W. Avoid thermal relief spokes on the tab pad to maximize heat transfer.

How does the body diode performance compare to discrete Schottky diodes?

The integrated body diode has V_SD = 1.3V at 1.6A and t_rr = 31–47ns-higher forward drop than Schottky but faster recovery than standard PN diodes. It's sufficient for low-duty-cycle freewheeling but not optimal for high-frequency synchronous rectification where ultra-low V_F is critical.
