Product details

Overview

IRLI2910PbF from Infineon Technologies (formerly International Rectifier) is a 100V, 31A logic-level N-channel Power MOSFET in TO-220 Full-Pak package, featuring 0.026Ω R_DS(on) at V_GS = 10V, 2.4°C/W R_θJC, and 2.5kV_RMS isolation - designed for high-efficiency DC-DC converters, motor drives, and industrial power switches where low conduction loss and thermal robustness are critical.

For engineers reviewing the IRLI2910 datasheet, IRLI2910 pinout, IRLI2910 application, or IRLI2910 equivalent, key selection criteria include its isolated TO-220 Full-Pak thermal performance, avalanche-rated operation (520mJ single-pulse), gate threshold of 1.0–2.0V, fast switching (t_d(off) = 49ns), and body diode recovery (t_rr = 240–350ns) in hard-switched topologies.

Technical Context

This HEXFET® device uses advanced silicon processing to achieve ultra-low on-resistance per die area while maintaining rugged unclamped inductive switching capability. Its isolated TO-220 Full-Pak construction integrates high-voltage insulation (2.5kV_RMS) and low thermal resistance (2.4°C/W junction-to-case), eliminating need for mica washers in heatsink mounting.

The MOSFET supports logic-level gate drive (V_GS(th) = 1.0–2.0V) and delivers 28S transconductance at 29A/50V, with gate charge profile optimized for high-frequency PWM control (Q_g = 140nC, Q_gd = 81nC). Its body diode exhibits 1.3V forward drop at 16A and controlled reverse recovery (Q_rr = 1.8–2.7µC).

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	100V - supports 48V bus systems with 2× safety margin against transients
R_DS(on) @ V_GS=10V	0.026Ω - enables ≤13W conduction loss at 20A continuous drain current
I_D @ T_C=25°C	31A - rated for sustained operation with active heatsinking
E_AS	520mJ - withstands unclamped inductive energy without failure in motor drive flyback
R_θJC	2.4°C/W - allows direct thermal path to heatsink with minimal interface resistance
t_r/t_f	100ns/55ns - supports >200kHz switching in resonant and hard-switched SMPS
V_SD	1.3V @ 16A - low body diode forward voltage reduces freewheeling loss in synchronous rectification

Pinout & Package

IRLI2910PbF uses the TO-220 Full-Pak package: insulated metal tab (drain-connected), 3-pin through-hole outline with integrated high-voltage isolation barrier (2.5kV_RMS), 4.8mm creepage distance, and single-screw or clip mounting. Thermal pad is electrically connected to drain.

Pin/Terminal	Circuit Role	Design Meaning
Gate (G)	Control input	Logic-compatible (1.0–2.0V threshold); accepts 5V microcontroller drive without level-shifting
Drain (D)	High-side power switch node	Internally bonded to insulated metal tab; provides primary thermal path and high-voltage isolation
Source (S)	Power return / reference node	Low-inductance source connection (L_S = 7.5nH); referenced to PCB ground plane

Key Features

Feature	Design Value
Isolated TO-220 Full-Pak	Eliminates external insulators; achieves 2.5kV_RMS isolation and 4.8mm creepage in standard footprint
Fully avalanche-rated	Guaranteed 520mJ single-pulse and 6.3mJ repetitive avalanche energy under defined test conditions
Ultra-low R_DS(on)	0.026Ω @ 10V ensures <1% conduction loss in 48V/20A power stages
Fast body diode recovery	t_rr = 240–350ns with Q_rr = 1.8–2.7µC enables efficient hard-switched freewheeling
Logic-level gate drive	V_GS(th) = 1.0–2.0V allows direct interfacing with 3.3V/5V controllers without gate drivers

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
IRF2910PbF	Same die, non-isolated TO-220AB package; no 2.5kV_RMS barrier; R_θJC = 1.7°C/W	Requires external insulator; unsuitable for floating-drain topologies	Select when cost-sensitive and isolation not required; higher thermal efficiency but added BOM complexity
STP110N10F7	100V, 110A, R_DS(on) = 0.0075Ω @ 10V; SuperFET F7 technology; lower Q_g (75nC)	Higher current rating; optimized for >300kHz ZVS/ZCS topologies	Select for higher-power density designs needing faster switching and lower gate drive loss

Compared with IRF2910PbF, IRLI2910PbF trades minor R_θJC penalty for full isolation and simplified assembly; versus STP110N10F7, it offers proven ruggedness and lower gate charge sensitivity in hard-switched industrial environments.

FAQ

What is the maximum continuous drain current at 100°C case temperature?

The IRLI2910PbF supports 22A continuous drain current at T_C = 100°C with V_GS = 10V, as specified in its Absolute Maximum Ratings table. This derating reflects thermal limits of the TO-220 Full-Pak package and must be validated with actual heatsink thermal resistance and ambient conditions.

Does the TO-220 Full-Pak package require thermal compound between tab and heatsink?

Yes - although the package provides electrical isolation, thermal interface material (TIM) is required between the insulated metal tab and heatsink to minimize R_θJA. The 2.4°C/W R_θJC rating assumes optimal TIM application and mounting pressure per the 1.1N·m screw torque specification.

Can IRLI2910PbF be used in synchronous rectification without an external Schottky diode?

Yes - its body diode has V_SD = 1.3V at 16A and t_rr = 240–350ns, making it suitable for synchronous rectification in medium-frequency DC-DC converters. However, for >300kHz operation or lowest conduction loss, an external Schottky may still be preferred.

What is the gate charge profile at V_DS = 80V and V_GS = 5V?

At V_DS = 80V and V_GS = 5V, the IRLI2910PbF exhibits Q_gd = 81nC and Q_gs = 20nC, resulting in total Q_g = 140nC. This profile supports efficient gate driving with moderate-speed controllers and defines Miller plateau timing in hard-switched applications.
