Product details

Overview

STI360N4F6 from STMicroelectronics is an automotive-grade N-channel Power MOSFET using STripFET™ F6 trench gate technology, rated for 40 V V_DS, 1.46 mΩ typ. R_DS(on) at V_GS = 10 V and I_D = 60 A, 120 A continuous drain current, and qualified to AEC-Q101. It operates in I²PAK (TO-262) package and targets high-current DC-DC converters and motor control stages in engine management systems.

For engineers reviewing the STI360N4F6 datasheet, STI360N4F6 pinout, STI360N4F6 application, or STI360N4F6 equivalent, key selection criteria include its low 0.5 °C/W R_thj-case, 304 nC total gate charge, 44 ns reverse recovery time, and AEC-Q101 qualification for under-hood switching use.

Technical Context

This MOSFET employs a refined trench-gate STripFET™ F6 structure to minimize conduction loss while maintaining robust avalanche capability (unclamped inductive switching tested per Figure 16). Its 1.46 mΩ typ. R_DS(on) enables high-efficiency 12 V/24 V automotive power stages with minimal thermal derating up to T_C = 100 °C.

The device delivers fast switching performance: 64 ns turn-on delay, 182 ns rise time, and 47 nC Q_rr with 2.1 A I_RRM, supporting hard-switched topologies up to ~100 kHz. Gate drive compatibility is ensured by V_GS(th) of 3–4.5 V and ±20 V V_GS rating.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	40 V - Maximum blocking voltage for 12 V/24 V automotive battery rail applications.
R_DS(on) typ.	1.46 mΩ at V_GS = 10 V, I_D = 60 A - Enables <1.5 W conduction loss at 120 A, reducing heatsink requirements.
I_D cont.	120 A at T_C = 25 °C - Supports high-current load switching without parallel devices in compact layouts.
Q_g	304 nC - Determines gate driver current demand; requires ≥60 mA average drive for 100 kHz switching.
R_thj-case max	0.5 °C/W - Allows direct mounting to chassis or heatsink for >250 W power dissipation at ΔT = 125 °C.
t_rr	44 ns - Limits switching losses during freewheeling in synchronous rectification and H-bridge motor drives.

Pinout & Package

STI360N4F6 is housed in the I²PAK (TO-262) package: 3-pin, insulated tab, through-hole mount, with drain connected to the exposed metal tab for thermal and electrical connection.

Pin/Terminal	Circuit Role	Design Meaning
1 (Source)	Source terminal	Low-side reference node; connects to ground or low-side switch node in half-bridge configurations.
2 (Gate)	Control input	High-impedance MOSFET gate requiring <100 nA leakage; driven by logic-level or dedicated gate driver.
3 (Drain / Tab)	Power output / heat path	Electrically and thermally connected to internal drain; must be isolated from PCB ground unless system design permits.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive under-hood operation across −40 °C to +175 °C junction temperature range.
Very low R_DS(on)	1.46 mΩ typ. reduces I²R losses by >35% vs prior-generation F5 MOSFETs at same die size.
High avalanche ruggedness	Rated for unclamped inductive switching (UIS) with guaranteed energy absorption per JEDEC JESD24-11.
Low gate charge	304 nC Q_g enables efficient 100 kHz+ PWM operation with standard 1-A gate drivers.
Low V_SD	1.3 V forward voltage at I_SD = 120 A supports efficient body-diode conduction during dead-time intervals.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel 40 V power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRF3205PbF	R_DS(on) = 8.0 mΩ (higher), Q_g = 71 nC (lower), not AEC-Q101 qualified	Suitable only for non-automotive industrial or consumer applications	Select only if AEC-Q101 compliance is unnecessary and thermal margin allows higher R_DS(on).
STL360N4F6	Same STripFET™ F6 die but in PowerFLAT™ 5x6 package; R_DS(on) = 1.55 mΩ, surface-mount only	Requires PCB redesign for SMT assembly; no through-hole option	Choose for space-constrained, high-density automotive PCBs where reflow compatibility is mandatory.

Compared with IRF3205PbF and STL360N4F6, STI360N4F6 uniquely balances AEC-Q101 compliance, through-hole I²PAK packaging, and industry-leading 1.46 mΩ R_DS(on), making it optimal for production automotive power stages requiring field-proven reliability and serviceable assembly.

FAQ

Is STI360N4F6 pin-compatible with STP360N4F6?

No. STI360N4F6 uses the I²PAK (TO-262) package with 3 pins in linear order (Source–Gate–Drain/Tab), while STP360N4F6 uses TO-220 with identical pinout but different mechanical footprint and thermal interface. PCB layout and heatsink mounting differ significantly.

What is the maximum safe operating area (SOA) at T_C = 100 °C?

Per Figure 2 in the datasheet, the SOA at T_C = 100 °C supports 120 A continuous current up to V_DS = 10 V, and 40 A up to V_DS = 40 V in single-pulse mode. Derating is required beyond these boundaries to avoid thermal runaway.

Does STI360N4F6 require a gate resistor for automotive EMI compliance?

Yes. A 4.7 Ω gate resistor is specified in the switching test circuit (Figure 13) to limit di/dt and suppress ringing. For CAN-bus adjacent systems, a 10–22 Ω resistor combined with ferrite bead filtering is recommended to meet CISPR 25 Class 5 radiated emissions limits.

Can STI360N4F6 replace older STB360N4F6 in existing designs?

Yes, with verification. STI360N4F6 shares identical electrical specs and I²PAK package with STB360N4F6 but features improved R_DS(on) (1.46 mΩ vs 1.65 mΩ) and tighter Q_g distribution. Layout and thermal interface remain compatible; no PCB change is needed.
