STMicroelectronics STL8DN6LF6AG

Overview

STL8DN6LF6AG from STMicroelectronics is an AEC-Q101 qualified dual N-channel 60 V Power MOSFET in PowerFLAT 5x6 double island package, featuring 27 mΩ max R_DS(on) at V_GS = 10 V, 32 A continuous drain current at T_C = 25 °C, and 55 W total power dissipation - designed for high-efficiency automotive switching applications including motor control and DC-DC conversion.

For engineers reviewing the STL8DN6LF6AG datasheet, STL8DN6LF6AG pinout, STL8DN6LF6AG application, or STL8DN6LF6AG equivalent, key selection criteria include dual-channel isolation capability, wettable flank package compatibility with automated optical inspection (AOI), low gate charge (27 nC), avalanche ruggedness (120 mJ E_AS), and thermal resistance (R_thJC = 2.7 °C/W).

Technical Context

This device implements ST's STripFET F6 trench-gate technology to achieve simultaneous low on-resistance and low gate charge. Its dual-channel layout enables independent control of two high-current paths within a single compact footprint, supporting half-bridge or synchronous rectifier topologies without cross-conduction risk when properly driven.

The PowerFLAT 5x6 double island package provides separate thermal islands for each channel, enabling independent heat spreading and improved thermal management under asymmetric load conditions. The wettable flank design ensures reliable solder joint inspection via AOI, critical for automotive-grade manufacturing traceability.

FAQ

What is the maximum allowable junction temperature for continuous operation?

The STL8DN6LF6AG has an operating junction temperature range of −55 °C to 175 °C. For continuous operation, the maximum sustained junction temperature is 175 °C, validated under AEC-Q101 stress testing. Derating is required above T_C = 100 °C, where I_D drops to 23 A per channel per datasheet Table 1.

Does this MOSFET require external gate resistors for automotive EMI compliance?

Yes - while the device's 7 ns fall time and 9.6 ns turn-on delay support fast switching, ST recommends a 4.7 Ω gate resistor (as used in Figure 12 test circuit) to dampen ringing and meet CISPR 25 Class 5 radiated emissions limits in motor drive applications.

Can both channels be paralleled to increase current capacity?

No - the two channels share no internal connection and have independent thermal islands, but their R_DS(on) mismatch (±15% typical) and gate threshold variation (1–2.5 V) make paralleling unsafe without active current balancing. They are intended for independent switching functions only.

Is the PowerFLAT 5x6 double island package lead-free and RoHS compliant?

Yes - the STL8DN6LF6AG uses ST's ECOPACK2-compliant PowerFLAT 5x6 double island WF type R package, fully lead-free and RoHS compliant per Directive 2011/65/EU, with halogen-free molding compound and NiPdAu plating on wettable flanks.
