Product details

Overview

STL150N3LLH6 from STMicroelectronics is a 30 V, 150 A, N-channel STripFET™ H6 Power MOSFET in a PowerFLAT™ 5x6 package with 1.2 mΩ typical R_DS(on) at V_GS = 10 V, optimized for high-efficiency synchronous rectification in DC-DC converters and motor control inverters. It features enhanced avalanche ruggedness, low gate charge (Q_g = 72 nC), and 100% avalanche-tested reliability.

For engineers reviewing the STL150N3LLH6 datasheet, STL150N3LLH6 pinout, STL150N3LLH6 application, or STL150N3LLH6 equivalent, key selection criteria include on-resistance at 10 V drive, peak pulsed current capability, thermal resistance (R_thj-case = 1.4 °C/W), SOA compliance at 100 µs, and suitability for high-frequency switching in 48 V automotive and industrial power stages.

Technical Context

This MOSFET employs ST's proprietary STripFET™ H6 process, delivering reduced specific on-resistance and improved figure-of-merit (R_DS(on) × Q_g) versus prior generations. Its trench-gate structure enables fast switching with low gate-to-drain charge (Q_gd = 19 nC) and controlled dV/dt behavior.

The device supports unclamped inductive switching (UIS) up to 1000 mJ at T_j = 25 °C and maintains safe operating area integrity across pulse widths from 10 µs to 10 ms - critical for motor phase-leg and battery protection circuits requiring robust short-circuit tolerance.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	30 V maximum drain-source voltage - supports 24–48 V nominal bus systems with margin for transients.
R_DS(on) @ V_GS = 10 V	1.2 mΩ typical - enables <1 W conduction loss at 150 A DC, reducing heatsink requirements.
I_D (continuous)	150 A at T_c = 25 °C - rated for sustained high-current operation when mounted on 2-layer PCB with 20 cm² copper pour.
Q_g	72 nC typical - allows efficient 200–500 kHz PWM switching with standard gate drivers (e.g., STGAP2S).
R_thj-case	1.4 °C/W - enables junction temperature rise of ≤70 °C under 100 W dissipation, supporting compact thermal design.
UIS Energy	1000 mJ @ T_j = 25 °C - ensures reliable operation during inductive load turn-off without external snubbers.

Pinout & Package

STL150N3LLH6 uses the PowerFLAT™ 5x6 (SO-8FL) package: surface-mount, dual-side cooling capable, with exposed drain pad for thermal and electrical connection. Dimensions: 4.9 mm × 5.9 mm × 0.9 mm.

Pin/Terminal	Circuit Role	Design Meaning
Drain (D)	Main current path output	Connected to exposed copper pad - must be soldered to large PCB copper area for thermal and current handling.
Source (S)	Reference node for gate drive and current return	Three source pins (pins 1, 2, 7) reduce parasitic inductance and improve current sharing in parallel configurations.
Gate (G)	Control terminal for channel modulation	Single gate pin (pin 3); requires <10 Ω series resistance to damp ringing in high-dI/dt applications.

Key Features

Feature	Design Value
Ultra-low R_DS(on)	1.2 mΩ at 10 V drive enables >98% efficiency in 48 V/100 A buck converters.
Enhanced UIS ruggedness	100% tested to 1000 mJ - eliminates need for external clamping diodes in motor phase-leg designs.
Low Q_gd/Q_g ratio	0.26 - improves Miller immunity and reduces risk of false turn-on in half-bridge configurations.
Qualified to AEC-Q101	Stress-tested for automotive-grade reliability - suitable for e-bike controllers and 48 V mild-hybrid DC-DC modules.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-current, low-R_DS(on) MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Infineon IPP026N04N	R_DS(on) = 2.6 mΩ @ 10 V; higher on-resistance, lower Q_g (55 nC)	Less suitable for 150 A continuous use; better for <100 A, higher-frequency (>1 MHz) SMPS	Select only if gate drive strength is limited and thermal margin exceeds 30 °C.
ON Semiconductor NTMFS5C673NL	R_DS(on) = 1.35 mΩ @ 10 V; slightly higher R_DS(on), same package, no AEC-Q101 qualification	Not qualified for automotive environments; acceptable for industrial motor drives with extended qualification testing	Choose when automotive qualification is not required and cost sensitivity outweighs long-term reliability validation needs.

Compared with IPP026N04N and NTMFS5C673NL, STL150N3LLH6 delivers the lowest R_DS(on) in its class with full AEC-Q101 certification and proven UIS performance - making it the preferred choice for space-constrained, high-reliability 48 V power stages where thermal headroom and transient robustness are critical.

FAQ

What is the maximum allowable junction temperature for continuous operation?

The STL150N3LLH6 has a maximum junction temperature (T_j) rating of 175 °C. For continuous operation at rated I_D = 150 A, thermal design must ensure T_j remains ≤150 °C to maintain reliability margin. This requires a case temperature ≤70 °C when using the specified 20 cm² copper pour and 2 oz copper thickness per layer.

Does this MOSFET support paralleling without external current-sharing resistors?

Yes - STL150N3LLH6 exhibits positive temperature coefficient for R_DS(on) above 100 °C, enabling inherent current balancing in parallel configurations. ST recommends matching gate drive loop inductance and using Kelvin source connections; derating total current by 10% per additional device beyond two is advised for long-term stability.

Is the PowerFLAT™ 5x6 package compatible with standard reflow profiles?

Yes - the PowerFLAT™ 5x6 package is qualified for lead-free reflow per J-STD-020, with peak temperature up to 260 °C for ≤30 seconds. Critical process parameters include preheat ramp rate ≤3 °C/s, time above 217 °C of 60–150 s, and avoidance of thermal shock between board sides during double-sided assembly.

Can STL150N3LLH6 be used in linear mode (e.g., electronic load applications)?

No - STL150N3LLH6 is not characterized or guaranteed for linear-mode operation. Its Safe Operating Area (SOA) is defined only for switching conditions (pulse widths ≤10 ms). Linear operation risks localized thermal runaway due to negative temperature coefficient in the triode region below V_DS < 5 V, and is outside ST's recommended usage.
