Product details
Overview
STL190N4F7AG from STMicroelectronics is an automotive-grade N-channel Power MOSFET with 40 V VDS, 1.68 mΩ typ. RDS(on) at VGS = 10 V and 17.5 A, 120 A continuous drain current (TC = 25 °C), and PowerFLAT™ 5x6 wettable flank package. It delivers high-efficiency switching in high-current DC-DC converters and motor control stages for 12 V/24 V automotive systems.
For engineers reviewing the STL190N4F7AG datasheet, STL190N4F7AG pinout, STL190N4F7AG application, or STL190N4F7AG equivalent, this page provides verified electrical ratings, thermal resistance (Rthj-case = 1.18 °C/W), gate charge (Qg = 41 nC), avalanche energy (EAS = 300 mJ), and AEC-Q101 qualification status to support robust power stage design.
Technical Context
This device uses STripFET™ F7 trench-gate technology to achieve ultra-low RDS(on) while minimizing Crss/Ciss ratio (70 pF / 3000 pF ≈ 0.023) for improved EMI immunity. Its low Qgd/Qg ratio (7 nC / 41 nC ≈ 0.17) supports fast, controllable turn-off in hard-switched topologies.
The PowerFLAT™ 5x6 WF type C package enables automated optical solder-joint inspection via wettable flanks and achieves Rthj-pcb = 31.3 °C/W on 1 in² FR-4 (2 oz Cu), supporting high-power density layouts without discrete heatsinks in many automotive applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 40 V - Maximum blocking voltage for 12 V/24 V battery rail switching |
| RDS(on) typ. | 1.68 mΩ at VGS = 10 V, ID = 17.5 A - Enables <1.2 W conduction loss at 90 A in typical layout |
| ID cont. | 120 A at TC = 25 °C - Limited by package thermal capacity, not silicon |
| EAS | 300 mJ at TJ = 25 °C - Supports unclamped inductive switching in motor drives |
| Qg | 41 nC - Determines gate driver power requirement and switching speed trade-off |
| Rthj-case | 1.18 °C/W - Enables direct thermal coupling to PCB copper or heatsink for thermal management |
| Crss/Ciss | 70 pF / 3000 pF - Low ratio improves noise immunity during high-dV/dt commutation |
Pinout & Package
STL190N4F7AG is housed in a PowerFLAT™ 5x6 WF type C package with exposed drain pad and wettable flank terminals for automated optical inspection. The 5-pin configuration features dual-source leads and single gate terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (Pad) | Main current path output | Exposed copper thermal pad - primary heat transfer path to PCB; electrically connected to drain |
| Source 1 | Current return path | Low-inductance source connection; used with Source 2 for parallel routing to reduce loop inductance |
| Source 2 | Current return path | Second dedicated source terminal - enables Kelvin sensing or split-source routing in high-precision gate drive |
| Gate | Control input | Single gate terminal with 100 nA leakage at VGS = 20 V - compatible with standard 3.3 V/5 V logic-level drivers |
| Drain (Lead) | Drain connection | Optional lead for auxiliary drain routing; electrically tied to main drain pad |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood operation across -55 °C to 175 °C junction temperature range |
| Wettable flank package | Enables AOI-compatible solder joint inspection on production lines without X-ray |
| High avalanche ruggedness | Rated for 35 A repetitive avalanche current and 300 mJ single-pulse energy - reduces need for external snubbers |
| Low Crss/Ciss ratio | 70 pF / 3000 pF = 0.023 - suppresses Miller-induced false turn-on in high-side configurations |
| Enhanced FoM (RDS(on) × Qg) | 1.68 mΩ × 41 nC = 68.9 - benchmark efficiency metric for high-frequency switching |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel 40 V Power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Infineon IPP026N04LG | RDS(on) = 2.6 mΩ (typ.), Qg = 45 nC, same PowerSO-10 package | Higher conduction loss; requires larger PCB copper area for thermal management | Preferred where legacy PowerSO-10 footprint compatibility is required over lowest RDS(on) |
| ON Semiconductor NTMFS4C09NT1G | RDS(on) = 1.85 mΩ (typ.), Qg = 43 nC, PowerFLAT™ 5x6 but non-wettable flank | Lacks AOI-compatible wettable flanks; lower avalanche rating (EAS = 220 mJ) | Acceptable for non-automotive industrial use where optical inspection is not mandated |
Compared with IPP026N04LG and NTMFS4C09NT1G, STL190N4F7AG offers the lowest RDS(on) and highest EAS in the 40 V class, with wettable flanks enabling automotive-grade process control - making it optimal for space-constrained, high-reliability vehicle subsystems.

FAQ
What is the maximum continuous drain current at 100 °C case temperature?
STL190N4F7AG maintains 120 A continuous drain current rating at TC = 100 °C per Table 2 of the datasheet. This reflects package-limited current capability rather than silicon limitation, which extends to 183 A at 25 °C. Thermal design must ensure case temperature does not exceed 100 °C under full-load conditions.
Is the gate threshold voltage compatible with 3.3 V microcontroller GPIOs?
No. VGS(th) ranges from 2 V to 4 V, but full enhancement requires VGS ≥ 10 V for rated RDS(on). Driving directly from 3.3 V GPIO will result in high conduction loss (>10× nominal). A gate driver with ≥10 V output or level-shifting circuitry is required for efficient operation.
Does STL190N4F7AG include an integrated Schottky diode?
No. It integrates a body diode inherent to the MOSFET structure, with VSD = 1.2 V at ISD = 35 A and trr = 43 ns. This is not a co-packaged Schottky diode. For synchronous rectification, external control of both high-side and low-side switches is needed to avoid body diode conduction.
What is the recommended PCB footprint for optical inspection of wettable flanks?
The recommended footprint is defined in Figure 20 of the datasheet: 4.15 mm × 4.45 mm solder mask opening for the central drain pad, with 0.30–0.50 mm wide side terminals and 0.25–0.40 mm solder mask dams between flanks. This ensures consistent meniscus formation for automated optical inspection without bridging.
