Product details
Overview
STB16PF06LT4 from STMicroelectronics is a P-channel enhancement-mode MOSFET rated for 60 V drain-source voltage, 16 A continuous drain current at 25°C, and 0.11 Ω typical RDS(on) at VGS = 10 V. It features low gate charge (11.4 nC), rugged unclamped inductive switching capability (250 mJ EAS), and is optimized for high-efficiency DC-DC converters and brushed DC motor control in industrial power stages.
For engineers reviewing the STB16PF06LT4 datasheet, STB16PF06LT4 pinout, STB16PF06LT4 application, or STB16PF06LT4 equivalent, key selection criteria include verified P-channel logic-level gate drive compatibility (VGS(th) = 1.5 V typ), thermal resistance (Rthj-case = 2.14 °C/W), avalanche energy rating, and D2PAK package mounting requirements for PCB thermal management.
Technical Context
This device employs ST's "Single Feature Size™" strip-based STripFET™ process to achieve high cell density and low on-resistance while maintaining robust avalanche performance. Its P-channel topology enables high-side switching without level-shifting circuitry, and its low threshold voltage supports direct interfacing with 3.3 V or 5 V microcontroller GPIOs.
The MOSFET exhibits fast switching dynamics (td(on) = 129 ns, tf = 19.5 ns) and controlled diode recovery (trr = 48.5 ns, Qrr = 87.3 nC), making it suitable for synchronous rectification and freewheeling paths where reverse recovery losses must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 60 V - Maximum blocking voltage in high-side switch configuration |
| RDS(on) (VGS = 10 V) | 0.11 Ω typ - Enables <1.4 W conduction loss at 16 A, reducing heatsink requirements |
| ID (TC = 25°C) | 16 A - Continuous current rating under ideal heatsinking conditions |
| EAS | 250 mJ - Energy-handling capability during unclamped inductive turn-off, critical for motor drive reliability |
| Qg | 11.4 nC - Gate charge determining driver strength requirement and switching loss trade-off |
| Rthj-case | 2.14 °C/W - Junction-to-case thermal resistance defining minimum heatsink interface performance |
| VGS(th) | 1.5 V typ - Ensures full enhancement with standard logic-level gate drive |
Pinout & Package
The STB16PF06LT4 is housed in a surface-mount D2PAK (TO-263) package with three terminals: Gate, Drain, and Source. The exposed drain pad provides low-inductance, high-current path and primary thermal conduction to the PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Gate (G) | Control electrode | Receives logic-level voltage to modulate channel conductivity; requires ≤±16 V absolute rating |
| Drain (D) | High-side power input/output node | Connected to load supply rail; electrically tied to exposed metal tab for thermal and current conduction |
| Source (S) | Reference terminal / return path | Typically connected to load ground or floating bus; defines VGS reference point |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(on) with P-channel architecture | 0.11 Ω @ VGS = 10 V enables high-side switching without external level shifters |
| Logic-level gate threshold | VGS(th) = 1.5 V typ allows direct drive from 3.3 V/5 V MCUs and digital controllers |
| Rugged avalanche capability | 250 mJ single-pulse EAS ensures survivability during inductive load transients |
| Optimized dynamic parameters | Qgd/Qg ratio of 0.41 improves switching controllability and reduces Miller-induced shoot-through risk |
Applications
| Brushed DC Motor Control | DC-DC Synchronous Buck Converter |
|---|---|

IC Role / Device Role / Timing Role: Reverse-polarity protected, low-loss conduction path replacing Schottky diodes. Use Value: RDS(on) < 0.13 Ω cuts forward drop by >70% vs. diode solution, improving efficiency and thermal margin. |
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 |
|---|---|---|---|
| IRF9540NPBF | RDS(on) = 0.2 Ω @ VGS = −10 V; higher threshold (−2–−4 V); TO-220 package | Lower current rating (19 A @ 25°C but derates faster); less suitable for compact SMT layouts | Prefer when through-hole mounting and lower gate charge sensitivity are acceptable |
| STP16PF06 | Same die, TO-220 package; identical electrical specs but different thermal path (Rthj-case = 2.5 °C/W) | No tape-and-reel option; manual assembly only; slightly higher thermal resistance limits high-power density use | Select for prototyping or low-volume through-hole designs where D2PAK reflow is unavailable |
Compared with IRF9540NPBF and STP16PF06, the STB16PF06LT4 offers superior RDS(on), lower gate charge, and SMT-compatible D2PAK packaging-making it optimal for space-constrained, high-efficiency industrial power stages requiring automated assembly and thermal performance.

FAQ
Is STB16PF06LT4 suitable for 3.3 V microcontroller gate drive?
Yes. With a typical gate threshold voltage of 1.5 V and guaranteed operation down to VGS = 4.5 V for full enhancement, the STB16PF06LT4 reliably turns on using standard 3.3 V GPIO outputs. Its low gate charge (11.4 nC) further ensures fast switching without excessive driver current demand.
What is the maximum safe operating temperature for continuous operation?
The device supports continuous operation up to Tj = 175°C, with derated current of 11.4 A at TC = 100°C. To maintain this junction temperature, the PCB layout must provide adequate copper area (≥1 inch² FR-4, 2 oz Cu) and ensure thermal resistance from junction to ambient remains below ~30 °C/W, including case-to-heatsink interface losses.
Does STB16PF06LT4 include an integrated body diode? What are its recovery characteristics?
Yes-it features a monolithic source-drain body diode with trr = 48.5 ns and Qrr = 87.3 nC at Tj = 150°C. These values indicate moderately fast, soft recovery behavior suitable for freewheeling in buck converters and motor drives, though external Schottky diodes may still be preferred in ultra-high-frequency (>1 MHz) or zero-voltage-switching topologies.
Can STB16PF06LT4 replace N-channel MOSFETs in high-side configurations?
No-it is a P-channel device intended for high-side switching *without* level shifting, unlike N-channel counterparts that require gate voltage above the source. Substituting it for an N-channel part would invert control logic and violate voltage ratings; proper replacement requires matching polarity, voltage class, RDS(on), and thermal profile-not just current rating.
