Product details

Overview

STL62P3LLH6 from STMicroelectronics is a P-channel enhancement-mode Power MOSFET using STripFET™ H6 trench-gate technology, rated for -30 V V_DS, 9 mΩ typ. R_DS(on) at V_GS = -10 V, and -62 A continuous drain current at T_C = 25 °C. It operates as a high-current, low-loss high-side switch in DC-DC converters, load switches, and battery protection circuits.

For engineers reviewing the STL62P3LLH6 datasheet, STL62P3LLH6 pinout, STL62P3LLH6 application, or STL62P3LLH6 equivalent, key selection criteria include its -30 V rating, 9 mΩ on-resistance, -62 A current capability, gate charge of 33 nC, and PowerFLAT™ 5x6 thermal performance with R_thj-case = 1.5 °C/W.

Technical Context

This device implements a trench-gate P-channel structure optimized for low R_DS(on) and low Q_g, enabling fast switching with reduced gate drive power loss. Its avalanche ruggedness supports robust operation under inductive load switching and fault conditions.

The PowerFLAT™ 5x6 package provides exposed drain pad for efficient heat transfer to PCB copper, with R_thj-pcb = 31.3 °C/W on 1 in² 2 oz Cu - critical for thermally constrained board-level designs requiring high pulsed current handling up to -248 A.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	-30 V - maximum blocking voltage for high-side switching in 24 V automotive and industrial rails
R_DS(on) (typ.)	9 mΩ at V_GS = -10 V - enables <1 W conduction loss at 33 A, reducing heatsink requirements
I_D (cont.)	-62 A at T_C = 25 °C - supports high-current load switching without derating in forced-air or heatsinked setups
Q_g	33 nC - allows efficient gate driving with standard logic-level controllers, minimizing driver IC stress
R_thj-case	1.5 °C/W - enables direct thermal coupling to heatsink or metal-core PCB for sustained 100 W dissipation
V_GS(th)	-1 V (min) - ensures reliable turn-on with -4.5 V logic-compatible gate drive, supporting 3.3 V/5 V controller interfaces
C_iss	3350 pF - defines input impedance for gate driver sizing and EMI filtering in high-frequency SMPS

Pinout & Package

STL62P3LLH6 uses the PowerFLAT™ 5x6 type R surface-mount package with an exposed drain pad (D) on the bottom side for thermal and electrical connection. The top-side has three terminals: Gate (G), Source (S), and Drain (D) - where Drain is internally connected to the exposed pad.

Pin/Terminal	Circuit Role	Design Meaning
G	Gate	Control terminal accepting negative V_GS; requires -10 V for full enhancement; threshold at -1 V
S	Source	Reference node for gate drive; tied to system ground or positive rail depending on high-side configuration
D (exposed pad)	Drain	Main current path output; electrically and thermally connected to PCB copper pour for low-inductance, high-power routing

Key Features

Feature	Design Value
Very low R_DS(on)	9 mΩ typ. at V_GS = -10 V reduces I²R losses by >30% vs prior-generation P-channel MOSFETs in same package
Low gate charge	33 nC total gate charge enables 500 kHz+ switching in synchronous buck converters with minimal driver power
High avalanche ruggedness	Rated for repetitive unclamped inductive switching - eliminates need for external snubbers in motor drive H-bridge legs
ECOPACK® compliant	Meets RoHS and halogen-free requirements per ST's PowerFLAT™ 5x6 type R environmental grade definition

Applications

Automotive Body Control Module (BCM)

Industrial 24 V DC Load Switch

Use Scenario: High-side power distribution for door locks, lighting, and window actuators in 12–24 V vehicle systems.

IC Role / Device Role / Timing Role: P-channel MOSFET used as protected high-side switch with integrated reverse polarity and overcurrent detection support.

Use Value: 9 mΩ R_DS(on) limits voltage drop to <0.6 V at 60 A, preserving headroom for downstream electronics during cold-crank conditions.

Use Scenario: Remote-controlled power enable for PLC I/O modules, solenoid drivers, and sensor power rails.

IC Role / Device Role / Timing Role: Main power switch controlled via microcontroller GPIO with active-low logic interface.

Use Value: -1 V V_GS(th) ensures clean turn-on with 3.3 V MCU outputs; 33 nC Q_g allows fast, low-jitter switching transitions.

Battery Protection Circuit (LiFePO₄)

DC-DC Synchronous Buck Converter (High-Side)

Use Scenario: Reverse-current blocking and over-discharge cutoff in 24 V battery packs for energy storage systems.

IC Role / Device Role / Timing Role: Back-to-back configured P-MOSFET providing bidirectional current control and fault isolation.

Use Value: -30 V rating accommodates 24 V nominal + surge margin; 1.5 °C/W R_thj-case sustains 10 s overload pulses without thermal shutdown.

Use Scenario: Upper switch in non-isolated 12 V → 3.3 V/5 V buck converter for FPGA or SoC power supplies.

IC Role / Device Role / Timing Role: High-side synchronous rectifier operating at 300–600 kHz with gate driver IC.

Use Value: 3350 pF C_iss and 287 pF Crss ensure predictable timing and minimal shoot-through risk when paired with matched low-side N-MOSFET.

Equivalent & Alternatives

The following parts are listed as comparable options for similar P-channel high-current switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRF4905PBF	R_DS(on) = 20 mΩ @ V_GS = -10 V; TO-220 package; R_thj-case = 1.7 °C/W	Requires heatsink mounting; higher conduction loss increases thermal footprint	Select when through-hole assembly or legacy footprint compatibility is required
DMT6009LPS-13	R_DS(on) = 9.5 mΩ @ V_GS = -10 V; PowerDI™ 5060 package; R_thj-pcb = 35 °C/W	Lower thermal efficiency on PCB; no exposed drain pad for direct heatsinking	Select when board space is constrained but thermal derating to ≤40 A is acceptable

Compared with IRF4905PBF and DMT6009LPS-13, STL62P3LLH6 delivers superior thermal performance in surface-mount form factor, lower gate charge for faster switching, and tighter R_DS(on) tolerance - making it optimal for compact, high-efficiency 24 V industrial and automotive power stages.

FAQ

What is the maximum safe operating temperature for STL62P3LLH6?

The junction temperature must not exceed 175 °C. At T_C = 25 °C, the device supports 100 W total dissipation; derating is required above 25 °C at 0.67 W/°C. PCB layout with ≥1 in² 2 oz Cu copper pour is essential to maintain R_thj-pcb = 31.3 °C/W and avoid thermal runaway under continuous -44 A load.

Can STL62P3LLH6 be driven directly by a 3.3 V microcontroller?

No - its V_GS(th) min is -1 V, but full enhancement requires V_GS ≤ -4.5 V for R_DS(on) ≤ 16 mΩ. A 3.3 V MCU cannot provide sufficient negative gate voltage. A level-shifting driver or charge pump is required to generate -4.5 V to -10 V gate drive referenced to the source node.

Does STL62P3LLH6 include integrated ESD or overvoltage protection?

No. It is a bare silicon Power MOSFET without integrated protection circuitry. External TVS diodes across V_DS and gate resistors with RC snubbers are recommended for automotive load-dump transients and inductive switching spikes, especially in BCM and motor drive applications.

How does the PowerFLAT™ 5x6 package affect PCB layout requirements?

The exposed drain pad must be soldered to a minimum 1 in² copper area with ≥4 thermal vias (0.3 mm diameter) connecting to inner/ground planes. Footprint dimensions require D2 = 4.15–4.45 mm and E2 = 3.50–3.70 mm per ST's recommended land pattern; insufficient copper or missing vias increase R_thj-pcb beyond 31.3 °C/W and risk thermal failure.
