Product details
Overview
STL9P2UH7 from STMicroelectronics is a P-channel enhancement-mode Power MOSFET using STripFET™ H7 trench-gate technology, rated for 20 V VDS, 0.0195 Ω RDS(on) (typ.) at VGS = 4.5 V, and 9 A continuous drain current at Tpcb = 25 °C. It operates in high-frequency switching roles with ultra-low gate charge (22 nC) and capacitance (Ciss = 2390 pF), deployed in load-switching circuits for portable power management.
For engineers reviewing the STL9P2UH7 datasheet, STL9P2UH7 pinout, STL9P2UH7 application, or STL9P2UH7 equivalent, key selection criteria include verified P-channel logic-level drive compatibility, avalanche ruggedness (100% UIS tested), thermal resistance to PCB (42 °C/W), and PowerFLAT™ 3.3×3.3 package footprint compliance.
Technical Context
This device implements a trench-gate P-channel structure optimized for low RDS(on) and minimized switching losses. Its gate threshold voltage (0.4–1.0 V) enables direct interfacing with 1.8 V/2.5 V/3.3 V logic controllers without level-shifting.
The integrated source-drain diode exhibits 15.8 ns reverse recovery time and 5.9 nC Qrr, supporting synchronous rectification and inductive load commutation. Thermal design relies on junction-to-PCB conduction (Rthj-pcb = 42 °C/W on 1 in² FR-4, 2 oz Cu).
Key Specifications

|---|---|
| VDS | 20 V - Maximum blocking voltage for low-voltage P-channel load switches |
| RDS(on) (typ.) | 0.0195 Ω @ VGS = 4.5 V - Enables <180 mW conduction loss at 9 A |
| ID (cont.) | 9 A @ Tpcb = 25 °C - Sustained current capability with board-level thermal management |
| Qg | 22 nC - Low gate drive energy supports >1 MHz PWM operation |
| Ciss | 2390 pF - Minimizes Miller effect and improves dv/dt immunity |
| Tj max | 150 °C - Junction temperature limit enabling operation in compact enclosures |
| VGS(th) | 0.4–1.0 V - Ensures turn-on with 1.8 V I/O rails without external bias |
Pinout & Package
STL9P2UH7 is housed in a surface-mount PowerFLAT™ 3.3×3.3 package with exposed drain pad for thermal and electrical performance. The package features 8 terminals in a single-row configuration with drain connected to pins 5–8, gate to pin 4, and source to pins 1–3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 (S) | Source | Common return path for load current; tied to ground plane in high-side switch configurations |
| 4 (G) | Gate | Control input requiring ≤±8 V rating; low 4.2 nC Qgs enables fast edge rates |
| 5, 6, 7, 8 (D) | Drain | Main power output node; thermally and electrically connected to exposed copper pad under package |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RDS(on) | 0.0195 Ω typ. at 4.5 V gate drive reduces conduction loss by >30% vs. legacy P-channel MOSFETs |
| Low gate charge | 22 nC total charge minimizes driver power and enables efficient 1–2 MHz switching |
| High avalanche ruggedness | 100% UIS-tested to 100 mJ ensures reliability in inductive load transients |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Infineon BSP296 | RDS(on) = 0.025 Ω @ 4.5 V; Qg = 28 nC; TO-263 package | Larger footprint and higher thermal resistance (Rthj-pcb ≈ 65 °C/W) | Prefer when through-hole assembly or higher surge current margin is required |
| Vishay SI2301DS | RDS(on) = 0.095 Ω @ 4.5 V; SOT-23 package; lower current rating (2.7 A) | Not suitable for >3 A continuous loads; limited thermal mass | Select only for space-constrained, low-current bias rail switching |
Compared with BSP296 and SI2301DS, STL9P2UH7 delivers superior RDS(on)/Qg ratio in a thermally optimized PowerFLAT™ package, making it optimal for high-efficiency, high-density 9 A load switching where PCB area and thermal dissipation are critical.

FAQ
What is the maximum safe operating temperature for STL9P2UH7?
The maximum operating junction temperature is 150 °C, validated per absolute maximum ratings. Derating begins above 100 °C case temperature, with continuous drain current dropping to 5.9 A at Tpcb = 100 °C. Thermal design must ensure Rthj-pcb ≤ 42 °C/W on a 1 in² FR-4 board with 2 oz copper to maintain reliability.
Can STL9P2UH7 be driven directly by a 3.3 V microcontroller GPIO?
Yes - its gate threshold voltage range (0.4–1.0 V) and guaranteed turn-on at VGS = 2.5 V make it fully compatible with 3.3 V logic. At 3.3 V, RDS(on) remains ≤0.025 Ω, delivering <225 mW conduction loss at 9 A, well within thermal limits for typical PCB layouts.
Does STL9P2UH7 include an integrated body diode, and what are its recovery characteristics?
Yes - it features a monolithic source-drain diode with 15.8 ns reverse recovery time (trr) and 5.9 nC reverse recovery charge (Qrr) at di/dt = 100 A/µs. These values are measured under standardized inductive switching conditions and support synchronous rectification in buck converters and flyback snubbers.
Is the PowerFLAT™ 3.3×3.3 package lead-free and RoHS-compliant?
Yes - STL9P2UH7 is manufactured in ST's ECOPACK®-compliant PowerFLAT™ 3.3×3.3 package, meeting RoHS Directive 2011/65/EU and REACH SVHC requirements. The package uses matte tin plating and is halogen-free per IEC 61249-2-21.
