Product details
Overview
STL210N4LF7AG from STMicroelectronics is an AEC-Q101 qualified N-channel automotive Power MOSFET in PowerFLAT™ 5x6 package, featuring 40 V VDS, 1.35 mΩ typ. RDS(on) at VGS = 10 V, 120 A continuous drain current, and low Crss/Ciss ratio for EMI immunity - deployed in high-current DC-DC converters and battery disconnect circuits.
For engineers reviewing the STL210N4LF7AG datasheet, STL210N4LF7AG pinout, STL210N4LF7AG application, or STL210N4LF7AG equivalent, this page delivers verified electrical ratings, thermal resistance (Rthj-case = 1 °C/W), gate charge (Qg = 56 nC), avalanche energy (EAS = 450 mJ), and wettable flank package layout details critical for automotive PCB assembly and thermal design.
Technical Context
This device employs STripFET™ F7 trench-gate technology to achieve ultra-low on-resistance while minimizing Ciss (4210 pF) and Crss (60 pF), enabling fast switching (td(on) = 15 ns, tf = 22 ns) with reduced EMI generation. Its 175 °C max junction temperature and 30 A repetitive avalanche current support robust operation under transient overloads.
The PowerFLAT™ 5x6 WF type C package integrates wettable flanks for automated optical solder-joint inspection and delivers 1 °C/W junction-to-case thermal resistance - optimized for double-sided cooling in space-constrained automotive modules where thermal management and AEC-Q101 reliability are mandatory.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 40 V - Maximum drain-source blocking voltage compatible with 12 V/24 V automotive systems and 48 V mild-hybrid architectures. |
| RDS(on) max | 1.6 mΩ at VGS = 10 V, TC = 25 °C - Enables <1.92 W conduction loss at 120 A, reducing heatsink requirements in high-efficiency power stages. |
| ID continuous | 120 A at TC = 25 °C - Sustained current capability limited by package thermal design, not silicon, supporting high-power load switching. |
| EAS | 450 mJ at Tj = 25 °C - Confirmed single-pulse avalanche energy rating ensures ruggedness during inductive turn-off transients in motor drives and solenoid control. |
| Qg | 56 nC - Total gate charge enables efficient driving with standard gate drivers (e.g., STGAP2SICSN), minimizing driver power dissipation. |
| Rthj-case | 1 °C/W - Junction-to-case thermal resistance allows direct thermal interface to heatsink or copper plane, enabling >100 W continuous power dissipation. |
| Crss/Ciss | 60/4210 pF - Low reverse transfer capacitance relative to input capacitance improves noise immunity and reduces Miller-induced shoot-through risk. |
Pinout & Package
STL210N4LF7AG uses the PowerFLAT™ 5x6 WF type C package (8-pin, exposed drain pad), with wettable flanks for AOI-compatible solder joint inspection. The thermally enhanced construction features a 5.0–5.4 mm × 6.0–6.1 mm footprint and 0.8–1.0 mm height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D (Pins 5, 6, 7, 8) | Drain (common source connection) | Exposed copper pad tied internally to all four drain terminals - primary thermal path and high-current return node; must be soldered to large PCB copper area. |
| G (Pin 4) | Gate | Control terminal requiring <56 nC charge for full enhancement; sensitive to ESD (±100 nA leakage at ±20 V); routed away from noisy traces. |
| S (Pins 1, 2, 3) | Source | Low-inductance source connection for Kelvin sensing or gate drive reference; pins 1–3 form parallel low-impedance return path for 120 A current. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control, body electronics, and ADAS power stages per stress test requirements. |
| Wettable flank package | Side-wettable leads enable automated optical inspection (AOI) of solder fillets - eliminating X-ray requirement for production line quality assurance. |
| High avalanche ruggedness | Rated for 30 A repetitive IAV and 450 mJ single-pulse EAS, enabling reliable operation in unclamped inductive switching without external snubbers. |
| Low Crss/Ciss ratio | 60/4210 pF ratio suppresses Miller feedback, improving switching stability in high-dV/dt environments like 48 V DC-DC converters. |
| Enhanced FoM (RDS(on) × Qg) | ~90 mΩ·nC - Benchmark figure of merit for high-current switching efficiency, directly reducing total switching + conduction losses. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel automotive power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Infineon BSC014N06LS | 60 V VDS, 1.4 mΩ RDS(on), PG-TDSON-8 package (no wettable flanks), Rthj-case = 1.1 °C/W | Lacks AEC-Q101 certification; suitable for industrial but not automotive qualification-critical designs. | Select when higher voltage margin (60 V) is needed and AOI inspection is not required. |
| ON Semiconductor NTMFS5C673NL | 60 V VDS, 1.35 mΩ RDS(on), SO-8FL package, Rthj-case = 1.4 °C/W, no AEC-Q101 rating | Lower thermal performance and no automotive qualification; Crss/Ciss ratio not specified for EMI optimization. | Choose only for cost-sensitive non-automotive applications where 40 V rating is insufficient. |
Compared with BSC014N06LS and NTMFS5C673NL, STL210N4LF7AG uniquely combines AEC-Q101 compliance, wettable flanks for automotive AOI, 40 V rating matched to 12/48 V systems, and best-in-class FoM - making it the only drop-in solution for thermally demanding, safety-certified automotive power stages.

FAQ
What is the maximum allowable gate-source voltage for STL210N4LF7AG?
The absolute maximum VGS is ±20 V, with gate-body leakage current specified at ±100 nA at ±20 V. Operation above ±16 V is not recommended for long-term reliability; typical gate drive uses 10 V for full enhancement and 0 V or –5 V for guaranteed turn-off in high-noise automotive environments.
Does STL210N4LF7AG require a gate resistor for safe switching?
Yes - a gate resistor (e.g., 4.7 Ω) is required to control dV/dt and prevent oscillation, especially given its 56 nC Qg and low Crss. The datasheet specifies switching times using RG = 4.7 Ω; lower values increase EMI risk and higher values degrade efficiency and thermal performance.
Can STL210N4LF7AG be used in parallel configurations?
Yes - its positive temperature coefficient of RDS(on) (normalized to 1.6× at 175 °C) enables inherent current sharing. Successful paralleling requires matched layout (symmetrical gate and power loops), identical gate drive, and thermal coupling via shared heatsink or copper plane to maintain <5 °C inter-device ΔT.
Is the PowerFLAT™ 5x6 package lead-free and RoHS compliant?
Yes - STL210N4LF7AG is manufactured in ST's ECOPACK2-compliant PowerFLAT™ 5x6 WF type C package, meeting RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) when sealed per specification. Lead finish is matte tin (Sn) over nickel.
