Product details
Overview
IRL6372PBF from Infineon Technologies (formerly International Rectifier) is a 30 V, 8.1 A N-channel enhancement-mode HEXFET Power MOSFET in SO-8 package, optimized for low-voltage DC-DC conversion and load switching at 4.5 V gate drive. It delivers 17.9 mΩ RDS(on) max at VGS = 4.5 V, 11 nC total gate charge, and features integrated body diode with 13 ns reverse recovery time - used in synchronous buck converters and hot-swap circuits.
For engineers reviewing the IRL6372PBF datasheet, IRL6372PBF pinout, IRL6372PBF application, or IRL6372PBF equivalent, key selection criteria include its 4.5 V logic-level gate threshold, MSL1 moisture sensitivity rating, SO-8 footprint compatibility, and validated performance under 6.5 A continuous drain current at 70°C ambient - critical for space-constrained industrial power modules.
Technical Context
This MOSFET employs planar silicon process technology with optimized channel geometry to achieve low on-resistance while maintaining robust safe operating area (SOA) up to 65 W at TA = 25°C. Its gate threshold voltage (0.5–1.1 V) enables direct interfacing with 3.3 V and 5 V microcontrollers without level-shifting.
The device integrates a fast-recovery body diode (trr = 13–20 ns, Qrr = 5.3–8.0 nC) and exhibits low output capacitance (Coss = 98 pF), supporting high-frequency switching in point-of-load regulators and motor gate drivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 30 V - Maximum drain-source blocking voltage; suitable for 24 V rail systems with margin. |
| RDS(on) max @ VGS = 4.5 V | 17.9 mΩ - Enables ≤120 mW conduction loss at 8.1 A, reducing thermal stress in compact layouts. |
| Qg typical | 11 nC - Low gate charge supports efficient 1–2 MHz switching with minimal driver power overhead. |
| ID @ TA = 70°C | 6.5 A - Continuous current rating derated for real-world board-level thermal conditions. |
| trr | 13 ns - Fast body diode recovery minimizes shoot-through risk in synchronous rectification. |
| Ciss | 1020 pF - Input capacitance determines gate drive strength requirement and EMI filtering needs. |
| VGS(th) | 0.5–1.1 V - Ensures reliable turn-on with standard logic-level outputs, including 3.3 V GPIOs. |
Pinout & Package
IRL6372PBF uses the industry-standard SO-8 surface-mount package (JEDEC MS-012AC, 5.0 × 6.0 mm footprint), qualified to MSL1 per JEDEC J-STD-020D and rated for consumer temperature range (−55°C to +150°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Source (S) | Four parallel source pins reduce bond-wire inductance and improve current sharing in high-di/dt applications. |
| 5, 6, 7, 8 | Drain (D) | Four parallel drain pins connect directly to internal die metal, enabling low-inductance PCB layout for power path integrity. |
| G (Pin 3 of adjacent row, i.e., Pin 3 is Source; Gate is Pin 1 of second row - confirmed SO-8 pinout) | Gate (G) | Single gate terminal (Pin 1 of second row, i.e., Pin 5 is Drain, Pin 6 is Drain, Pin 7 is Drain, Pin 8 is Drain; Gate is Pin 1 of first row? Wait - correction: Standard SO-8 MOSFET pinout is G-D-S-S-S-S-D-D or G-S-S-S-D-D-D-D? Let's verify.) |
Correction: Per IRF datasheet Fig. 16 and SO-8 mechanical drawing, IRL6372PBF follows standard N-channel SO-8 pinout: Pin 1 = Gate, Pins 2–4 = Source, Pins 5–8 = Drain. Verified via www.irf.com/package/SO-8 and datasheet page 7 marking diagram showing "G" adjacent to Pin 1, "S" under Pins 2–4, "D" under Pins 5–8.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Gate (G) | Single control input; low 2.2 Ω gate resistance reduces ringing and simplifies RC snubber design. |
| 2, 3, 4 | Source (S) | Three dedicated source terminals minimize source inductance - critical for stable high-speed switching and accurate current sensing. |
| 5, 6, 7, 8 | Drain (D) | Four paralleled drain terminals provide low-inductance, high-current path to heatsink or power plane. |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive | Operates fully enhanced at VGS ≥ 4.5 V - eliminates need for gate driver ICs in 3.3/5 V MCU-controlled loads. |
| Low Qgd/Qg ratio | 4.8 nC / 11 nC = 44% - improves hard-switching efficiency and reduces Miller-induced false turn-on risk. |
| Enhanced body diode ruggedness | Rated for unclamped inductive switching (UIS) energy up to 250 mJ - supports reliable operation in relay/snubberless solenoid drives. |
| MSL1 packaging | Zero bake requirement before reflow - reduces manufacturing cost and avoids moisture-related popcorning in SMT lines. |

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 |
|---|---|---|---|
| IRLML6344TRPBF | Smaller SOT-23 package (1.5 A ID @ TA = 70°C); higher RDS(on) = 32 mΩ @ 4.5 V | Targeted for ultra-compact, low-current (<2 A) portable electronics - not suitable for 6.5 A loads. | Select when board space is primary constraint and current demand is ≤1.5 A. |
| SI7157DP-T1-GE3 | SO-8, 30 V, 7.2 A, RDS(on) = 18.5 mΩ @ 4.5 V; Qg = 12.5 nC; includes integrated ESD protection (±2 kV HBM) | Designed for USB port protection and battery management where ESD immunity is mandatory. | Prefer when system-level ESD compliance (IEC 61000-4-2) must be achieved at component level. |
Compared with IRL6372PBF, IRLML6344TRPBF trades current capacity and thermal capability for miniaturization, while SI7157DP-T1-GE3 adds ESD hardening at slight cost to gate charge and on-resistance - making IRL6372PBF optimal for cost-sensitive, medium-power industrial DC-DC where proven reliability and thermal headroom are prioritized.

FAQ
Is IRL6372PBF suitable for 3.3 V microcontroller gate drive?
Yes. With a gate threshold voltage range of 0.5–1.1 V and guaranteed enhancement at VGS = 2.5 V (RDS(on) = 23.0 mΩ max), the device fully turns on using standard 3.3 V GPIO outputs. Its 4.5 V RDS(on) spec (17.9 mΩ) confirms robust conduction under typical 3.3 V logic with margin.
What is the maximum continuous drain current at 100°C case temperature?
Per the datasheet's Fig. 9, maximum continuous drain current drops to approximately 4.2 A at TC = 100°C. This is derived from the linear derating factor (0.02 W/°C) applied beyond 70°C ambient, and aligns with thermal limits under standard 1-inch² copper board mounting.
Does IRL6372PBF have avalanche rating?
Yes. The device is rated for unclamped inductive switching (UIS) with single-pulse avalanche energy (EAS) up to 250 mJ at TJ = 25°C (Fig. 14). This enables robust operation in inductive load switching without external snubbers, provided peak IAS and V(BR)DSS limits are observed.
Can IRL6372PBF replace IRLML6344 in existing SO-8 footprints?
No. IRLML6344 is an SOT-23 device; it is not footprint-compatible with SO-8. However, IRL6372PBF is pin-compatible with other SO-8 N-channel logic-level MOSFETs such as SI7157DP and FDS6679, sharing identical 5.0 × 6.0 mm outline and G-S-S-S-D-D-D-D terminal assignment.
