Product details

Overview

STL60N3LLH5 from STMicroelectronics is an N-channel 30 V PowerFLAT™ (5×6) STripFET™ V MOSFET optimized for high-efficiency switching in DC-DC converters and motor control. It delivers R_DS(on) = 6.3 mΩ @ V_GS = 10 V, 8.5 A; Q_g = 8 nC; avalanche energy E_AS = 120 mJ; and continuous drain current I_D = 17 A (T_C = 25 °C, PCB-mounted). It is used in synchronous buck converters for server VRMs.

For engineers reviewing the STL60N3LLH5 datasheet, STL60N3LLH5 pinout, STL60N3LLH5 application, or STL60N3LLH5 equivalent, key selection criteria include low R_DS(on) × Q_g figure of merit, high pulsed current capability (I_DM = 68 A), thermal resistance to PCB (R_thj-pcb = 31.3 °C/W), and unclamped inductive switching ruggedness.

Technical Context

This MOSFET employs ST's STripFET™ V process to minimize conduction and switching losses simultaneously. Its gate charge profile supports fast turn-on/turn-off with low drive power, while the integrated source-drain diode exhibits t_rr = 22 ns and Q_rr = 15 nC at T_j = 150 °C, enabling efficient synchronous rectification.

The device is characterized for operation up to 150 °C junction temperature and features a robust safe operating area (SOA) validated for unclamped inductive switching. Its PowerFLAT™ (5×6) package provides exposed drain pad for low thermal resistance to PCB (R_thj-pcb = 31.3 °C/W on 1 in² 2 oz Cu).

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	30 V - Maximum blocking voltage for 24 V input systems with margin
R_DS(on) max	7.1 mΩ @ V_GS = 10 V, I_D = 8.5 A - Enables <1 W conduction loss at 17 A
Q_g	8 nC - Reduces gate drive power and enables >1 MHz switching in hard-switched topologies
I_D (PCB)	17 A continuous @ T_C = 25 °C - Rated for FR-4 board with 1 in² copper area

Pinout & Package

STL60N3LLH5 uses the PowerFLAT™ (5×6) surface-mount package with exposed drain pad (pin 1–3: Source; pin 4–5: Gate; bottom thermal pad: Drain). The package measures 5.0 × 6.0 × 0.83 mm and is RoHS-compliant and ECOPACK® certified.

Pin/Terminal	Circuit Role	Design Meaning
1–3 (Source)	Source connection (common return path)	Low-inductance parallel terminals reduce source inductance in high-di/dt switching
4–5 (Gate)	Control terminal	Dual gate pins lower gate loop inductance and improve switching consistency
Drain (exposed pad)	Main current path and thermal interface	Direct thermal coupling to PCB improves power dissipation and thermal stability

Key Features

Feature	Design Value
R_DS(on) × Q_g benchmark	53.1 mΩ·nC - Industry-leading FOM for 30 V MOSFETs, reducing total switching + conduction loss
High avalanche ruggedness	E_AS = 120 mJ - Eliminates need for external snubbers in inductive load circuits
Low gate drive power requirement	Q_g = 8 nC @ V_GS = 10 V - Compatible with low-current gate drivers (e.g., STMicro's STGAP2S)
Optimized body diode	t_rr = 22 ns, Q_rr = 15 nC - Reduces shoot-through risk and recovery loss in synchronous buck stages
Thermally enhanced package	R_thj-pcb = 31.3 °C/W - Allows full 17 A rating on standard FR-4 without thermal vias or heatsinks

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel 30 V PowerFLAT™ MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Infineon BSC014N03LS	R_DS(on) = 1.4 mΩ (lower), Q_g = 12.5 nC (higher), same PowerFLAT™ (5×6) footprint	Better conduction loss but higher gate drive demand; requires stronger driver	Select when lowest R_DS(on) dominates over switching loss and gate drive capability exists
ON Semiconductor NTMFS4C03NT1G	R_DS(on) = 6.7 mΩ, Q_g = 7.2 nC, same package, slightly lower E_AS (100 mJ)	Nearly identical performance envelope; reduced avalanche margin	Select when cost sensitivity outweighs need for maximum unclamped inductive ruggedness

Compared with BSC014N03LS and NTMFS4C03NT1G, STL60N3LLH5 offers the best balance of ultra-low Q_g, proven 120 mJ avalanche capability, and stable R_DS(on) across temperature-making it preferred for thermally constrained, transient-heavy industrial and telecom power stages.

FAQ

What is the maximum continuous drain current for STL60N3LLH5 under PCB-mount conditions?

The maximum continuous drain current is 17 A when mounted on a standard FR-4 PCB with 1 in² of 2 oz copper (per datasheet Table 1, ID(2)). This rating assumes T_C = 25 °C and accounts for R_thj-pcb = 31.3 °C/W. At T_C = 100 °C, derated current drops to 10.6 A.

Does STL60N3LLH5 support gate drive at 4.5 V logic levels?

Yes. R_DS(on) is specified at 8.6 mΩ max @ V_GS = 4.5 V and I_D = 8.5 A (Table 5), confirming full enhancement at 4.5 V. However, Q_g remains 8 nC, so gate driver peak current must still support ~1–2 A for sub-10 ns rise times.

Is the PowerFLAT™ (5×6) package lead-free and RoHS-compliant?

Yes. The STL60N3LLH5 is manufactured in ST's ECOPACK®-compliant PowerFLAT™ (5×6) package, meeting RoHS Directive 2011/65/EU and REACH SVHC requirements. Lead finish is matte tin, and the package is halogen-free per ST's environmental specifications.

Can STL60N3LLH5 be used in parallel configurations?

Yes, but with design precautions. Its positive temperature coefficient for R_DS(on) (Figure 11) supports current sharing. Use matched gate resistors, symmetrical layout, and individual gate routing to minimize loop inductance imbalance. Derate total current by ≥15% versus sum of individual ratings due to thermal coupling on shared PCB area.
