Product details
Overview
STD20NF06LAG from STMicroelectronics is an AEC-Q101 qualified N-channel Power MOSFET in DPAK (TO-252) package, designed for high-efficiency switching applications. It features 60 V VDS, 32 mΩ typ. RDS(on) at VGS = 10 V, 24 A continuous drain current, and 100% avalanche tested ruggedness. It serves as the primary switch in isolated DC-DC converters for telecom and computing infrastructure.
For engineers reviewing the STD20NF06LAG datasheet, STD20NF06LAG pinout, STD20NF06LAG application, or STD20NF06LAG equivalent, key selection criteria include its low gate charge (13 nC), exceptional dv/dt capability (10 V/ns), AEC-Q101 qualification, thermal resistance (Rthj-case = 2.5 °C/W), and integrated source-drain diode with 56 ns reverse recovery time.
Technical Context
This device employs ST's STripFET II process to minimize input capacitance (Ciss = 660 pF) and gate charge-enabling fast switching with reduced driver loss. Its rugged unclamped inductive switching performance is validated by 225 mJ single-pulse avalanche energy rating and 96 A pulsed drain current capability.
The MOSFET supports operation up to 175 °C junction temperature and delivers stable on-resistance over temperature (±20% variation from 25 °C to 150 °C). Its 1.5 V forward diode voltage at 24 A enables efficient synchronous rectification or freewheeling in hard-switched topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 60 V - Supports 48 V telecom bus and 36 V automotive systems with margin |
| RDS(on) max | 40 mΩ at VGS = 10 V - Limits conduction loss to ≤11.5 W at 17 A continuous |
| Qg | 13 nC - Enables <1 µs turn-on with 15 mA gate drive, reducing switching loss |
| dv/dt rating | 10 V/ns - Withstands fast transient coupling in high-noise power stages |
| EAS | 225 mJ - Absorbs inductive energy without failure during unclamped switching |
| Rthj-case | 2.5 °C/W - Allows 60 W dissipation with ≤150 °C case-to-ambient rise under heatsink |
| VSD | 1.5 V at ISD = 24 A - Reduces freewheeling loss vs. external Schottky in buck/LLC designs |
Pinout & Package
DPAK (TO-252) package: surface-mount, single-tab thermally enhanced outline with exposed drain pad (Pin 2/TAB), gate (Pin 1), and source (Pin 3). Tab is electrically connected to drain and must be soldered to PCB copper for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G (Pin 1) | Gate control terminal | Receives 0–10 V logic-level signal; 13 nC total charge requires low-impedance driver |
| D (Pin 2 / TAB) | Drain connection + thermal path | Exposed metal tab ties directly to drain; must be routed to high-current net and thermal plane |
| S (Pin 3) | Source reference node | Serves as return path for load current and gate drive reference; connects to power ground |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive powertrain and body electronics per stress test requirements |
| 100% avalanche tested | Each unit passes single-pulse EAS = 225 mJ test-ensures robustness in inductive fault conditions |
| Low Ciss / Coss | 660 pF / 170 pF - Minimizes capacitive switching loss and improves EMI behavior |
| Exceptional dv/dt immunity | 10 V/ns rated - Prevents false turn-on in high-side configurations with fast-rising VDS |
| STripFET II process | Enables 32 mΩ RDS(on) in DPAK - Delivers higher current density than standard Trench MOSFETs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel 60 V power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRFZ44NPBF | RDS(on) = 28 mΩ (typ), but no AEC-Q101 qualification; Qg = 67 nC - 5× higher than STD20NF06LAG | Not suitable for automotive or high-reliability telecom; better for cost-sensitive industrial motor controls | Select only if gate drive strength permits high Qg and qualification is not required |
| STP20NF06L | Same die, TO-220 package - Rthj-case = 1.5 °C/W, but larger footprint and through-hole mounting | Preferred for prototyping or low-volume thermal testing; unsuitable for automated SMT production | Choose when thermal performance outweighs board space constraints and assembly method allows leaded parts |
Compared with IRFZ44NPBF and STP20NF06L, STD20NF06LAG uniquely balances AEC-Q101 compliance, low gate charge, and DPAK manufacturability-making it optimal for volume automotive and telecom power modules where reliability, efficiency, and SMT yield are jointly critical.

FAQ
Is STD20NF06LAG suitable for high-frequency switching above 1 MHz?
No. While its 13 nC gate charge supports fast switching, its output capacitance (Coss = 170 pF) and 56 ns reverse recovery time limit practical operation to ≤500 kHz in hard-switched topologies. For >1 MHz designs, consider GaN or SiC alternatives with lower Coss and zero reverse recovery.
What is the maximum allowable PCB copper area for thermal performance in DPAK layout?
Per ST's datasheet, a minimum 1-inch² FR-4 board with 2 oz copper achieves Rthj-pcb = 50 °C/W. To approach the 2.5 °C/W Rthj-case rating, the exposed drain tab must connect to ≥300 mm² of internal or external copper pour with ≥4 thermal vias (0.3 mm diameter, 0.8 mm pitch).
Does STD20NF06LAG require a gate resistor for safe operation?
Yes. A series gate resistor (typically 4.7–10 Ω) is required to dampen ringing, control dV/dt during turn-on/off, and prevent oscillation due to gate loop inductance. ST's recommended test circuit uses RG = 4.7 Ω for 10 A resistive load switching.
Can STD20NF06LAG replace older STD20NF06L in existing designs?
Yes-STD20NF06LAG is a direct drop-in replacement for STD20NF06L with identical pinout, electrical specs, and DPAK package. The "A" suffix denotes updated marking and minor thermal data revision (Rthj-case unchanged); no layout or firmware changes are needed.
