Product details
Overview
STB30NF20L from STMicroelectronics is an automotive-grade N-channel enhancement-mode Power MOSFET in D²PAK package, rated for 200 V VDS, 0.066 Ω typ. RDS(on) at VGS = 5 V, 30 A continuous drain current at TC = 25 °C, and 150 W total power dissipation. It delivers rugged avalanche performance (140 mJ EAS) and low gate charge (65 nC), enabling high-efficiency switching in motor control and DC-DC converters.
For engineers reviewing the STB30NF20L datasheet, STB30NF20L pinout, STB30NF20L application, or STB30NF20L equivalent, key selection criteria include its AEC-Q101 qualification, 1 °C/W RthJC, 100% avalanche-tested reliability, and optimized FoM for thermally constrained automotive power stages.
Technical Context
This MOSFET employs ST's "single feature size" strip-based STripFET™ process to achieve high cell density, resulting in low on-resistance and minimized intrinsic capacitance (Ciss = 1990 pF, Coss = 297 pF). Its gate threshold voltage (1–3 V) ensures robust turn-on with standard 5 V logic drivers.
The device integrates a fast-recovery source-drain diode (trr = 140 ns at Tj = 25 °C, Qrr = 0.75 µC) and supports high dv/dt (10 V/ns) operation under inductive switching, with safe operating area validated up to 120 A pulsed drain current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 200 V - Supports 12 V/24 V automotive systems with ≥2× bus overvoltage margin |
| RDS(on) max | 0.075 Ω - Ensures ≤1.7 W conduction loss at 15 A, critical for thermal management in sealed enclosures |
| ID cont. @ TC=25°C | 30 A - Enables single-device implementation in 300–500 W motor drive half-bridges |
| Qg | 65 nC - Reduces gate drive power and enables use of low-current drivers (e.g., TC4427) |
| EAS | 140 mJ - Guarantees unclamped inductive switching survival without external snubbers |
| trr | 140 ns - Limits switching losses and EMI during freewheeling in buck and H-bridge topologies |
| RthJC | 1 °C/W - Allows direct heatsink mounting for >100 W sustained power dissipation without derating |
Pinout & Package
D²PAK (TO-263) package: surface-mount, isolated tab (drain-connected), 3-pin configuration with exposed copper thermal pad for enhanced heat transfer.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G) | Gate | Control terminal; accepts 0–10 V logic-level drive; 65 nC total charge requires <1 µs rise time for full-speed switching |
| 2 (D / TAB) | Drain / Thermal Tab | Main high-side power path; electrically and thermally connected to exposed metal tab-must be soldered to PCB copper pour or heatsink |
| 3 (S) | Source | Reference node for gate drive and current sensing; ties to low-side switch or ground plane in half-bridge configurations |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive temperature range (−40 to 175 °C junction), vibration, and humidity per JESD47 |
| 100% avalanche tested | Each unit subjected to single-pulse unclamped inductive switching at IAR = 30 A, ensuring field reliability in motor fault conditions |
| Low Coss & Crss | 297 pF Coss, 42 pF Crss - Minimizes Miller effect, enabling stable high-frequency (>100 kHz) operation without oscillation |
| Excellent FoM (RDS(on) × Qg) | 4.9 Ω·nC - Benchmark efficiency metric confirming superior trade-off between conduction and switching loss |
| Fast body diode | trr = 140 ns, Qrr = 0.75 µC - Reduces reverse recovery loss and EMI in synchronous rectification and bidirectional converters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel 200 V power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRFP260N | Higher RDS(on) (0.04 Ω min but 0.072 Ω typ), no AEC-Q101, TO-247 package | Non-automotive industrial use only; requires larger heatsink due to higher RthJA | Prefer when cost sensitivity outweighs automotive compliance and surface-mount assembly needs |
| IXTH30N20L | Lower Qg (45 nC), same VDS/RDS(on), TO-247 package, no AEC-Q101 | Better high-frequency efficiency but lacks automotive qualification and thermal performance (RthJC = 1.2 °C/W) | Select for non-automotive SMPS where gate drive loss dominates and board space allows through-hole mounting |
Compared with IRFP260N and IXTH30N20L, STB30NF20L uniquely combines AEC-Q101 qualification, D²PAK surface-mount compatibility, and best-in-class FoM (4.9 Ω·nC), making it the only drop-in solution for thermally dense, safety-critical automotive power stages requiring zero requalification.

FAQ
Is STB30NF20L suitable for 48 V automotive systems?
Yes. With 200 V VDS rating and AEC-Q101 qualification, STB30NF20L supports 48 V mild hybrid architectures-including DC-DC conversion and bidirectional power flow-while maintaining safe voltage margin against transients up to ISO 7637-2 Pulse 5a (75 V). Its 175 °C max junction temperature enables operation in engine bay environments.
What is the recommended gate resistor value for optimal switching performance?
A 4.7 Ω gate resistor is validated in the datasheet for resistive load switching (Figure 13), yielding td(on) = 14 ns and tf = 14 ns. For inductive loads, reduce to 2.2–3.3 Ω to minimize Qgd-dominated turn-off delay while avoiding gate ringing-verified via Figure 14 test circuit with VDD = 160 V and ID = 30 A.
Does STB30NF20L require a Kelvin source connection for precision current sensing?
No. STB30NF20L uses standard 3-pin D²PAK packaging without dedicated Kelvin source. For accurate current sensing, place the sense resistor in the source path with low-inductance layout, or use external shunt + isolated amplifier. The device's 1 µA IDSS at 200 V ensures minimal leakage error in high-side sensing configurations.
Can STB30NF20L replace STB20NF20 in existing designs?
Yes-with design verification. STB30NF20L offers 50% higher ID (30 A vs. 20 A), lower RDS(on) (0.066 Ω vs. 0.095 Ω), and identical D²PAK footprint and pinout. Thermal design must accommodate higher power capability: ensure heatsink interface resistance ≤ 0.5 °C/W to maintain Tj < 150 °C at full load.
