Product details

Overview

IRL540SPBF 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 fast switching with 64 nC total gate charge and operates up to 175 °C junction temperature, making it suitable for high-efficiency DC-DC converters and motor drive half-bridges.

For engineers reviewing the IRL540SPBF datasheet, IRL540SPBF pinout, IRL540SPBF application, or IRL540SPBF equivalent, key selection criteria include its logic-level gate drive compatibility with 3.3 V/5 V microcontrollers, repetitive avalanche rating (E_AR = 15 mJ), low R_DS(on) at 4 V gate drive (0.11 Ω), and surface-mount D2PAK thermal performance (R_thJC = 1.0 °C/W).

Technical Context

This MOSFET uses third-generation trench-gate silicon technology optimized for low conduction loss and robust switching under inductive loads. Its dynamic dv/dt rating (5.5 V/ns) and unclamped inductive switching capability (E_AS = 440 mJ) support reliable operation in hard-switched topologies without external snubbers.

The device integrates a fast-recovery body diode (t_rr = 200–260 ns, Q_rr = 1.7–2.9 μC) and features tightly controlled gate threshold voltage (V_GS(th) = 1.0–2.0 V), enabling predictable turn-on behavior across temperature and process variation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	100 V - supports 48 V bus systems with 2× safety margin against transients
R_DS(on) @ V_GS = 5 V	0.077 Ω - enables ≤2.2 W conduction loss at 17 A, reducing heatsink requirements
Q_g	64 nC - determines gate driver power demand and switching speed in PWM circuits
I_D (continuous, T_C = 25 °C)	28 A - delivers high current density in compact D2PAK footprint without derating
T_J max	175 °C - allows operation in sealed enclosures or high-ambient industrial environments
E_AS	440 mJ - sustains single-pulse inductive energy without failure in motor commutation

Pinout & Package

D2PAK (TO-263) surface-mount package with exposed drain pad for low thermal resistance (R_thJC = 1.0 °C/W); 3-terminal configuration optimized for high-current PCB mounting on 1" FR-4 board (P_D = 3.7 W).

Pin/Terminal	Circuit Role	Design Meaning
Tab / Pin 2 (Drain)	High-current output node	Electrically connected to exposed copper pad; primary heat path to PCB ground plane
Pin 1 (Gate)	Control input	Logic-level compatible (V_GS(th) = 1.0–2.0 V); requires <9.4 nC charge for full enhancement
Pin 3 (Source)	Reference return path	Completes power loop; internal source inductance (L_S = 7.5 nH) affects di/dt-induced voltage spikes

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 MCU systems
Repetitive avalanche rated	Withstands 15 mJ per pulse indefinitely under controlled conditions, enabling rugged flyback and buck-boost designs
Dynamic dv/dt immunity	Rated for 5.5 V/ns, suppressing false turn-on during high-speed switching in noisy power stages
Low R_DS(on) at elevated temperature	R_DS(on) increases only ~1.5× from 25 °C to 125 °C, maintaining efficiency in thermally constrained layouts

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
STP100N10F7	R_DS(on) = 0.0085 Ω @ 10 V (lower), but V_GS(th) = 2.5–4.5 V (not logic-level); Q_g = 105 nC (higher)	Requires gate driver for 3.3 V control; better for high-frequency SMPS where gate loss dominates	Select when higher V_GS drive is available and lowest R_DS(on) is critical
IRF540N	R_DS(on) = 0.044 Ω @ 10 V but 0.11 Ω @ 4 V; V_GS(th) = 2.0–4.0 V; no avalanche rating	Not logic-level compatible; unsuitable for direct 3.3 V MCU drive; lacks EAS/E_AR specs	Choose only if 10 V gate drive is guaranteed and avalanche robustness is not required

Compared with STP100N10F7 and IRF540N, the IRL540SPBF uniquely combines true logic-level operation (V_GS(th) ≤ 2.0 V), specified R_DS(on) at 4 V, and documented repetitive avalanche capability-making it the preferred choice for space-constrained, microcontroller-driven power stages requiring ruggedness and simplicity.

FAQ

What is the maximum continuous drain current for IRL540SPBF at 100 °C case temperature?

The IRL540SPBF supports 20 A continuous drain current at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the D2PAK package under sustained high-power operation and must be validated against actual PCB layout and heatsinking in the target application.

Does IRL540SPBF have a specified body diode reverse recovery time?

Yes, the IRL540SPBF datasheet specifies t_rr = 200–260 ns at T_J = 25 °C, I_F = 28 A, and di/dt = 100 A/μs. This parameter is critical for synchronous rectification and half-bridge operation, where slow recovery can cause cross-conduction losses or voltage overshoot.

Is IRL540SPBF RoHS-compliant and halogen-free?

Yes, the IRL540SPBF is lead (Pb)-free and halogen-free, conforming to Vishay's material categorization standard (document 99912). The "PbF" suffix explicitly denotes RoHS-compliant termination finish, verified per JEDEC J-STD-609.

Can IRL540SPBF be used with a 3.3 V microcontroller GPIO without a gate driver?

Yes, the IRL540SPBF is a logic-level MOSFET with V_GS(th) = 1.0–2.0 V and R_DS(on) = 0.11 Ω at V_GS = 4 V. A 3.3 V GPIO can fully enhance the device, though layout must minimize gate loop inductance to ensure clean switching edges in high-di/dt applications.

What is the thermal resistance from junction to case (R_thJC) for IRL540SPBF?

The IRL540SPBF has a maximum junction-to-case thermal resistance (R_thJC) of 1.0 °C/W, measured from die to the exposed drain tab. This value assumes proper soldering to a large copper area on FR-4 PCB and is essential for calculating junction temperature rise under steady-state power dissipation.
