Product details

Overview

STU10P6F6 from STMicroelectronics is a P-channel -60 V, 0.13 Ω typ. R_DS(on), -10 A Power MOSFET in IPAK (TO-251) package, fabricated using STripFET™ F6 trench-gate technology. It delivers high avalanche ruggedness (80 mJ E_AS) and low gate charge (6.4 nC), enabling efficient high-side switching in DC-DC converters, motor drivers, and load-switching circuits.

For engineers reviewing the STU10P6F6 datasheet, STU10P6F6 pinout, STU10P6F6 application, or STU10P6F6 equivalent, key selection criteria include its -60 V V_DS, thermal resistance of 7.5 °C/W (j-case), 175 °C max junction temperature, and compatibility with standard gate-drive voltages down to -4 V threshold.

Technical Context

This device operates as a high-voltage P-channel enhancement-mode MOSFET with fully specified avalanche capability and optimized dynamic parameters for hard-switching topologies. Its STripFET™ F6 process enables low R_DS(on) while maintaining robust safe operating area (SOA) up to 10 ms at T_C = 25 °C.

The IPAK package provides mechanical stability and thermal performance suitable for surface-mount PCBs with moderate power dissipation requirements. Gate drive characteristics-including Q_g = 6.4 nC, Q_gd = 1.7 nC, and C_iss = 340 pF-support fast turn-on/turn-off with minimal driver loss.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	-60 V - Maximum drain-source blocking voltage for high-side switch applications requiring ≥60 V rail isolation.
R_DS(on) typ.	0.13 Ω @ V_GS = -10 V, I_D = -5 A - Enables ≤0.65 W conduction loss at 10 A continuous current in thermally managed designs.
I_D cont.	-10 A @ T_C = 25 °C - Supports sustained load currents up to 10 A when mounted on heatsinked PCBs.
E_AS	80 mJ - Single-pulse avalanche energy rating ensures reliability under inductive switching transients without external snubbers.
Q_g	6.4 nC - Low total gate charge reduces driver power consumption and enables use with low-current gate drivers (e.g., microcontroller GPIO).
R_thj-case	7.5 °C/W - Thermal resistance from junction to case allows ~4.7 W power dissipation before reaching 175 °C junction limit at 25 °C case temperature.
t_r/t_f	5.3 ns / 3.7 ns - Fast switching transitions minimize overlap losses in PWM-based power stages operating up to 500 kHz.

Pinout & Package

STU10P6F6 is housed in an IPAK (TO-251) package with three leads: Drain (Tab), Source (Pin 1), and Gate (Pin 2). The metal tab is electrically connected to the Drain terminal and serves as the primary thermal path to the PCB copper pour.

Pin/Terminal	Circuit Role	Design Meaning
Tab (Drain)	Main current-carrying terminal (high-side switch node)	Electrically tied to internal drain region; requires isolation from heatsink unless referenced to system ground; primary thermal interface.
Pin 1	Source	Reference node for gate drive; connects to system ground or load return in high-side configuration; carries full load current.
Pin 2	Gate	Control input; driven negative relative to source to turn on; threshold range -2 V to -4 V ensures compatibility with standard logic-level gate drivers.

Key Features

Feature	Design Value
Very low R_DS(on)	0.13 Ω typ. at -10 V V_GS enables <1 W conduction loss at 9 A, reducing thermal design burden in compact power modules.
Low gate charge	6.4 nC total gate charge minimizes switching energy loss and supports direct MCU GPIO driving with RC gate networks.
High avalanche ruggedness	80 mJ single-pulse E_AS eliminates need for external clamping diodes in relay/snubberless inductive load switching.
Extended junction temperature	175 °C max T_j rating permits operation in automotive under-hood and industrial ambient environments up to 125 °C with proper derating.
ECOPACK® compliant	Meets RoHS and halogen-free requirements per ST's environmental compliance program for industrial and automotive supply chains.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP10P6F6	Same die, TO-220 package; R_thj-case = 5 °C/W; higher thermal performance but through-hole mounting required.	Better suited for heatsink-mounted, high-power discrete designs where board space allows leaded components.	Select when thermal budget is tighter than 7.5 °C/W and through-hole assembly is acceptable.
STD10P6F6	Same die, DPAK (TO-252) package; R_thj-case = 4.29 °C/W; surface-mount compatible with higher thermal efficiency than IPAK.	Ideal for automated SMT production lines needing optimal thermal performance in space-constrained DC-DC modules.	Choose for highest thermal efficiency in SMT designs where footprint and reflow compatibility are critical.

Compared with STP10P6F6 (TO-220) and STD10P6F6 (DPAK), STU10P6F6 offers a balanced trade-off: IPAK provides better thermal performance than SO-8 equivalents while retaining surface-mount compatibility and lower profile than TO-220-making it optimal for mid-power industrial PCBs with mixed assembly constraints.

FAQ

What is the maximum continuous drain current for STU10P6F6 at 100 °C case temperature?

The maximum continuous drain current (I_D) for STU10P6F6 is -7.2 A at T_C = 100 °C, as specified in Table 2 of the datasheet. This derating reflects thermal limitations of the IPAK package; operation above this current requires active cooling or pulse-width reduction to maintain junction temperature ≤175 °C.

Does STU10P6F6 require a gate resistor for safe operation?

A gate resistor is recommended to control dV/dt and prevent oscillation during switching. Typical values range from 10 Ω to 100 Ω depending on drive strength and layout parasitics. The device's low Q_g (6.4 nC) allows fast switching even with modest gate drive, but uncontrolled ringing can cause shoot-through or EMI issues without proper gate damping.

Can STU10P6F6 be used in linear mode (as a pass transistor)?

No-STU10P6F6 is not characterized or guaranteed for linear (ohmic) operation. Its Safe Operating Area (SOA) curve in Figure 2 shows limited capability for DC or long-pulse linear use. For constant-current regulation or analog pass applications, dedicated linear MOSFETs or bipolar transistors with SOA-rated operation should be selected instead.

Is the metal tab of STU10P6F6 electrically isolated from other pins?

No-the metal tab is internally connected to the Drain terminal. When mounted on a PCB, the tab must either be electrically isolated from the heatsink or tied to the same potential as the drain node. Insulating pads or shoulder washers are required if the heatsink is grounded or at a different potential.
