Product details

Overview

STN3P10F6 from STMicroelectronics is a P-channel enhancement-mode Power MOSFET using STripFET™ F6 trench-gate technology, rated for -100 V drain-source voltage, 0.136 Ω typical R_DS(on) at -10 V V_GS, -3 A continuous drain current (T_pcb = 25 °C), and housed in an SOT-223 package. It serves as a high-efficiency low-side switch in DC-DC converters and load switching circuits.

For engineers reviewing the STN3P10F6 datasheet, STN3P10F6 pinout, STN3P10F6 application, or STN3P10F6 equivalent, key selection criteria include its -100 V blocking capability, low gate charge (16.5 nC), avalanche ruggedness, thermal resistance (46 °C/W on FR-4), and SOT-223 footprint compatibility with board-level power management layouts.

Technical Context

This device operates as a normally-off P-channel switch requiring negative gate drive relative to source. Its trench-gate STripFET™ F6 structure enables reduced R_DS(on) and gate charge versus prior generations, supporting higher efficiency in medium-voltage switching applications up to 175 °C junction temperature.

The integrated body diode exhibits 1.1 V forward voltage at -3 A and 26.5 ns reverse recovery time under defined inductive switching conditions, enabling use in synchronous rectification and freewheeling paths where fast diode recovery is required.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	-100 V - Maximum drain-to-source blocking voltage; defines usable input voltage range in high-side or low-side configurations
R_DS(on) typ.	0.136 Ω @ V_GS = -10 V, I_D = -1.5 A - Directly determines conduction loss and thermal rise at rated current
I_D cont.	-3 A @ T_pcb = 25 °C - Continuous current rating under standard PCB thermal conditions; derates to -2 A at 100 °C
Q_g	16.5 nC - Total gate charge; governs driver strength requirement and switching energy loss
R_thj-pcb	46 °C/W - Junction-to-PCB thermal resistance on 1 in² FR-4, 2 oz Cu; used to calculate junction temperature rise
V_GS(th)	-2 to -4 V - Gate threshold voltage range; defines minimum negative gate bias needed to initiate conduction
C_iss	900 pF - Input capacitance at V_DS = -25 V; impacts gate drive loop stability and turn-on speed

Pinout & Package

SOT-223 package: surface-mount, 4-pin thermally enhanced plastic case with exposed drain tab (pins 2 and 4 internally connected to drain). Standard JEDEC MO-178AC outline; recommended footprint per Figure 17.

Pin/Terminal	Circuit Role	Design Meaning
G (Pin 1)	Gate	Control terminal; requires negative voltage relative to source to turn on; 16.5 nC total charge must be driven
S (Pin 3)	Source	Reference node for gate drive and current return path; electrically isolated from PCB ground unless tied externally
D (Pins 2 & 4)	Drain	Main power output terminal; internally shorted across two pins for lower inductance and improved thermal conduction to PCB copper

Key Features

Feature	Design Value
Very low R_DS(on)	0.136 Ω typ. at -10 V V_GS - Enables <1 W conduction loss at -3 A, reducing heatsink need in space-constrained designs
Low gate charge	16.5 nC total - Allows use of low-power gate drivers and reduces switching loss in high-frequency operation
High avalanche ruggedness	Rated for single-pulse avalanche energy per SOA curve - Supports robust operation during inductive load transients without external snubbers
ECOPACK® compliant	Meets RoHS and halogen-free requirements - Ensures compliance with environmental regulations for industrial and consumer end equipment

Applications

Use Value: -2 to -4 V V_GS(th) enables precise analog dimming control; low R_DS(on) ensures <0.5% current error across 0–3 A range.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRF9530NPBF	R_DS(on) = 0.3 Ω @ -10 V (higher), Q_g = 60 nC (much higher), TO-220 package	Requires larger PCB area and heatsink; unsuitable for high-frequency or space-constrained designs	Choose only if legacy TO-220 footprint is mandatory and thermal budget permits higher losses.
DMG2305UVT-7	R_DS(on) = 0.045 Ω @ -4.5 V (lower), but V_DS = -20 V (significantly lower), SOT-23 package	Limited to ≤24 V systems; insufficient for 48 V industrial or automotive inputs	Select when low gate drive voltage (-4.5 V) and ultra-low R_DS(on) are critical, and voltage stress remains below 20 V.

Compared with IRF9530NPBF and DMG2305UVT-7, STN3P10F6 uniquely balances -100 V rating, 0.136 Ω conduction loss, and SOT-223 thermal performance-making it optimal for 36–48 V industrial switching where both voltage headroom and board-area efficiency matter.

FAQ

What is the maximum safe operating voltage for STN3P10F6 in continuous DC applications?

The absolute maximum drain-source voltage is -100 V, but continuous operation should remain within the Safe Operating Area (SOA) limits defined in Figure 2 of the datasheet. At DC, derating is required above 25 °C ambient due to thermal constraints-maximum sustainable V_DS drops as current or temperature increases. For reliable long-term use, ST recommends staying ≥20% below -100 V under worst-case transient conditions.

Can STN3P10F6 be used in linear (analog) regulation mode?

Yes, but with strict thermal management: its R_DS(on) and SOA allow limited linear operation only at low V_DS × I_D products. For example, dissipating >0.5 W requires substantial copper area or forced cooling. The device is optimized for switching, not linear regulation-use dedicated LDOs or regulators for precision analog control.

Does STN3P10F6 require a gate resistor for ESD protection or switching control?

A series gate resistor (typically 4.7–47 Ω) is recommended to dampen ringing and limit peak gate current during fast transitions. While not required for ESD protection (IGSS is ±100 nA), it improves electromagnetic compatibility and prevents driver overstress. Values below 1 Ω risk oscillation; above 100 Ω slows switching and increases loss.

Is the SOT-223 package lead-free and RoHS-compliant?

Yes-STN3P10F6 carries ECOPACK® certification, meeting RoHS Directive 2011/65/EU and being halogen-free per IEC 61249-2-21. The SOT-223 package uses matte tin plating over copper leads and complies with JEDEC J-STD-020 moisture sensitivity level 1 (unlimited floor life at ≤30 °C/85% RH).
