Product details

Overview

IRL2910STRL from Infineon Technologies (formerly International Rectifier) is a logic-level N-channel enhancement-mode Power MOSFET in D2PAK (TO-262) package, rated for 100V V_DSS, 55A continuous drain current at T_C = 25°C, and ultra-low 0.026Ω R_DS(on) at V_GS = 10V. It features fast switching (t_r = 100ns), full avalanche rating (E_AS = 520mJ), and surface-mount capability for high-current DC-DC converters and motor drive half-bridges.

For engineers reviewing the IRL2910STRL datasheet, IRL2910STRL pinout, IRL2910STRL application, or IRL2910STRL equivalent, key selection criteria include logic-level gate drive compatibility (V_GS(th) = 1.0–2.0V), thermal resistance (R_θJC = 0.75°C/W), body diode recovery (t_rr = 240–350ns), and avalanche ruggedness for inductive load switching.

Technical Context

This fifth-generation HEXFET device uses advanced silicon processing to minimize conduction loss while maintaining robust dv/dt immunity (5.0 V/ns) and fast turn-on/turn-off dynamics (t_d(on) = 11ns, t_f = 55ns). Its low gate charge (Q_g = 140nC) and Miller charge (Q_gd = 81nC) support efficient high-frequency PWM operation up to several hundred kHz.

The integrated source inductance (L_S = 7.5nH) and optimized die layout reduce parasitic ringing during hard-switching. The device's fully rated avalanche capability enables reliable unclamped inductive switching without external snubbers in motor control and solenoid drivers.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	100 V - Withstands 100V drain-source blocking voltage before avalanche onset
R_DS(on) @ V_GS = 10V	0.026 Ω - Enables ≤1.5W conduction loss at 55A, critical for thermally constrained PCBs
I_D @ T_C = 25°C	55 A - Maximum continuous current with case temperature maintained at 25°C
E_AS	520 mJ - Single-pulse avalanche energy rating ensures reliability under inductive fault conditions
Q_g	140 nC - Total gate charge determines driver strength requirement for <100ns switching transitions
t_r/t_f	100/55 ns - Fast rise/fall times enable high-efficiency operation in 100–500 kHz SMPS designs
R_θJC	0.75 °C/W - Low junction-to-case thermal resistance supports direct heatsink mounting in high-power applications

IC Role / Device Role / Timing Role: High-side and low-side power switch; handles 55A peak phase current with <100ns dead-time control.

Use Value: Low R_DS(on) minimizes conduction loss at high duty cycles; avalanche rating absorbs back-EMF spikes during commutation.

Use Scenario: Primary-side switch in isolated 400W forward or LLC resonant converters for factory automation PLCs.

IC Role / Device Role / Timing Role: Main power switch operating at 200–300 kHz with synchronous rectification on secondary side.

Use Value: 140nC Q_g enables efficient gate driving with low-power ICs; 0.75°C/W R_θJC allows direct heatsink mounting without thermal vias.

Automotive Body Control Modules

High-Current Solid-State Relays

Use Scenario: Load switching for headlights, cooling fans, and seat actuators in 12V/24V vehicle architectures.

IC Role / Device Role / Timing Role: Logic-driven high-side switch with integrated diagnostics via source-sense pin (external resistor).

Use Value: V_GS(th) of 1.0–2.0V ensures turn-on with automotive MCU outputs; 175°C T_J(max) supports under-hood placement.

Use Scenario: Replacement for electromechanical relays in industrial control panels handling 30–50A resistive/inductive loads.

IC Role / Device Role / Timing Role: Bidirectional switching element with body diode conducting reverse current during AC zero-crossing.

Use Value: 520mJ E_AS prevents failure during inductive turn-off transients; D2PAK footprint simplifies mechanical mounting and thermal management.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel logic-level power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRF3205PbF	R_DS(on) = 0.008Ω @ 10V (lower), but V_GS(th) = 2.0–4.0V (not logic-level)	Requires 10V gate drive; unsuitable for 3.3V/5V MCU direct drive	Select only if higher gate voltage is available and lower R_DS(on) justifies added drive complexity
STP55NF06L	R_DS(on) = 0.018Ω @ 10V, Q_g = 85nC (lower), but E_AS = 320mJ (reduced)	Lower switching loss but reduced avalanche margin for inductive loads	Preferable in high-frequency SMPS where avalanche stress is minimal; avoid in motor drives with high L×di/dt

Compared with IRF3205PbF and STP55NF06L, IRL2910STRL uniquely balances logic-level compatibility, high avalanche energy, and low thermal resistance-making it optimal for space-constrained, inductive-load applications requiring robustness without gate-driver overhead.

FAQ

Is IRL2910STRL suitable for 3.3V microcontroller gate drive?

Yes. With a gate threshold voltage (V_GS(th)) of 1.0–2.0V and full enhancement achievable at V_GS = 4.0V (R_DS(on) = 0.040Ω), the device operates reliably with 3.3V logic outputs. However, for lowest R_DS(on) (0.026Ω), a 5V or 10V gate drive is recommended to ensure minimal conduction loss.

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

The datasheet specifies I_D = 39A at T_C = 100°C and V_GS = 10V. This derating reflects thermal limits-not electrical limits-and assumes adequate heatsinking. At ambient temperatures above 70°C, PCB copper area and airflow must be validated per AN-994 footprint guidelines.

Does IRL2910STRL have a built-in ESD protection diode on the gate?

No. The device does not integrate gate ESD protection. External Zener clamping (e.g., 12V TVS between gate and source) is strongly recommended in systems exposed to handling or board-level ESD events, especially given its ±16V absolute maximum V_GS rating.

Can IRL2910STRL replace IRL2910L in a design?

Yes-electrically identical-but the IRL2910STRL uses surface-mount D2PAK packaging while IRL2910L is through-hole TO-262. Mechanical redesign is required for pad layout and thermal relief. The SMD version offers lower profile and better automated assembly compatibility, but requires careful reflow profiling due to its large thermal mass.
