Product details

Overview

IRL540STRR from Vishay Siliconix is a logic-level N-channel power MOSFET in D2PAK (TO-263) package, rated for 100 V V_DS, 28 A continuous drain current at T_C = 25 °C, and R_DS(on) = 0.077 Ω at V_GS = 5 V. It supports repetitive avalanche operation up to 15 mJ and operates up to 175 °C junction temperature, making it suitable for high-current DC-DC converters and motor drive half-bridges.

For engineers reviewing the IRL540STRR datasheet, IRL540STRR pinout, IRL540STRR application, or IRL540STRR equivalent, key selection criteria include its logic-level gate drive compatibility with 4–5 V microcontrollers, low R_DS(on) enabling high-efficiency switching at moderate currents, and robust thermal performance on PCB-mount configurations.

Technical Context

This device belongs to Vishay's third-generation surface-mount power MOSFET family optimized for fast switching and ruggedized operation. Its design integrates a HEX-4 die in D2PAK, delivering lowest possible on-resistance among SMT packages while maintaining high dv/dt immunity (5.5 V/ns) and unclamped inductive switching capability.

The IRL540STRR features a monolithic body diode with t_rr = 200–260 ns and Q_rr = 1.7–2.9 μC, enabling efficient synchronous rectification and freewheeling in hard-switched topologies. Gate charge parameters (Q_g = 64 nC, Q_gd = 27 nC) support predictable turn-on/turn-off timing under 9 Ω gate resistance.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	100 V - Withstands bus voltages up to 100 V in DC-DC, motor control, and lighting applications without breakdown.
R_DS(on) @ V_GS = 5 V	0.077 Ω - Enables <1.5 W conduction loss at 17 A, supporting high-efficiency 12–48 V systems.
I_D (continuous, T_C = 25 °C)	28 A - Supports high-current loads such as BLDC motor phases or industrial solenoid drivers.
Q_g	64 nC - Determines gate drive power requirement; compatible with standard MOSFET drivers like TC4420 or UCC27531.
E_AS	440 mJ - Allows safe operation under unclamped inductive switching events common in relay/snubberless AC switching.
T_J max	175 °C - Permits reliable operation in sealed enclosures or high-ambient environments without derating penalties.
dv/dt rating	5.5 V/ns - Resists false turn-on during fast voltage transients in noisy industrial power stages.

Pinout & Package

D2PAK (TO-263) surface-mount package with exposed drain pad for thermal and electrical connection; 3-pin configuration (G, D, S), lead (Pb)-free and halogen-free construction per Vishay specification.

Pin/Terminal	Circuit Role	Design Meaning
G (Gate)	Control electrode	Accepts logic-level 4–5 V drive; threshold voltage 1.0–2.0 V ensures TTL/CMOS compatibility.
D (Drain)	High-side power terminal	Connected to exposed copper pad on underside; primary thermal path and high-voltage node.
S (Source)	Reference and return path	Low-inductance source connection; internal LS = 7.5 nH minimizes switching ringing in high-di/dt circuits.

Key Features

Feature	Design Value
Logic-level gate drive	Operates fully enhanced at V_GS = 4 V, eliminating need for gate boosters in 3.3 V/5 V MCU-based designs.
Repetitive avalanche rated	Rated for 15 mJ repetitive avalanche energy, enabling robustness in inductive load switching without external snubbers.
D2PAK thermal performance	R_thJC = 1.0 °C/W enables >100 W dissipation with minimal heatsink when mounted on 1" FR-4 PCB.
Dynamic dv/dt immunity	5.5 V/ns rating prevents spurious turn-on during fast edge transitions in high-noise motor drive inverters.
Body diode recovery	t_rr = 200–260 ns and Q_rr = 1.7–2.9 μC reduce switching losses and EMI in freewheeling paths.

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
IRF540N	V_GS(th) = 2–4 V; R_DS(on) = 0.044 Ω @ 10 V but requires 10 V gate drive for full enhancement.	Not logic-level compatible; unsuitable for direct 3.3 V/5 V MCU drive without level-shifting.	Select IRL540STRR when gate drive voltage ≤5 V is required; IRF540N only where 10 V gate supply is available.
STP100N10F7	R_DS(on) = 0.0085 Ω @ 10 V, Q_g = 105 nC, D²PAK package, but V_GS(th) = 2.5–4.5 V.	Higher gate charge increases driver loss; lower R_DS(on) benefits only at >30 A continuous current.	IRL540STRR offers better gate drive compatibility and lower Q_g for 5–25 A logic-driven applications; STP100N10F7 preferred only for ultra-low-loss >30 A designs with 10 V drive.

Compared with IRF540N and STP100N10F7, the IRL540STRR uniquely balances logic-level operability, moderate R_DS(on), and low Q_g-making it optimal for cost-sensitive, space-constrained 5 V–driven power stages where gate drive simplicity and thermal margin outweigh ultra-low on-resistance needs.

FAQ

What is the maximum continuous drain current for IRL540STRR at 100 °C case temperature?

The IRL540STRR supports 20 A continuous drain current at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limits of the D2PAK package and must be validated against actual board layout and airflow conditions. The IRL540STRR maintains R_DS(on) stability across this range due to its positive temperature coefficient.

Is IRL540STRR RoHS-compliant and halogen-free?

Yes, the IRL540STRR is lead (Pb)-free and halogen-free, conforming to Vishay's material categorization per document 99912. It meets RoHS Directive 2011/65/EU requirements and is marked with "-GE3" suffix in ordering codes (e.g., SiHL540STRL-GE3), confirming full compliance for use in environmentally regulated markets.

Does IRL540STRR have an integrated body diode, and what are its key recovery characteristics?

Yes, the IRL540STRR includes an integral reverse p–n junction body diode. Its key recovery specs are t_rr = 200–260 ns and Q_rr = 1.7–2.9 μC at T_J = 25 °C, IF = 28 A, di/dt = 100 A/μs. These values enable efficient freewheeling in non-synchronous buck or half-bridge topologies without excessive switching loss or voltage overshoot.

What is the thermal resistance from junction to case (R_thJC) for IRL540STRR?

The maximum junction-to-case (drain) thermal resistance R_thJC for IRL540STRR is 1.0 °C/W, measured from die junction to the exposed drain pad. This low value enables high-power dissipation-up to 150 W at T_C = 25 °C-and is critical for thermal design when using copper pour or external heatsinks attached to the D2PAK drain tab.

Can IRL540STRR be used in avalanche mode, and what energy levels are rated?

Yes, the IRL540STRR is repetitively avalanche-rated with E_AR = 15 mJ and single-pulse E_AS = 440 mJ. These ratings apply under defined test conditions (V_DD = 25 V, L = 841 μH, R_g = 25 Ω, I_AS = 28 A). The IRL540STRR's ruggedized die design ensures reliable operation during inductive turn-off transients without external protection.
