Product details
Overview
PHP174NQ04LT from NXP Semiconductors (formerly Philips) is a logic-level N-channel TrenchMOS™ power MOSFET in TO-220AB (SOT78) package, rated for 40 V VDS, 75 A ID, 250 W Ptot, and 3.6 mΩ RDS(on) @ VGS = 10 V, used in high-current DC switching applications such as motor drives and uninterruptible power supplies.
For engineers reviewing the PHP174NQ04LT datasheet, PHP174NQ04LT pinout, PHP174NQ04LT application, or PHP174NQ04LT equivalent, key selection criteria include logic-level gate drive compatibility (VGS(th) = 1–2 V), low on-resistance at 5 V gate drive (RDS(on) ≤ 4.4 mΩ), avalanche ruggedness (560 mJ), thermal resistance to mounting base (0.6 K/W), and TO-220AB mechanical compatibility with heatsink mounting.
Technical Context
This device implements a trench-gate vertical DMOS structure optimized for logic-level gate drive, enabling direct interface with 3.3 V or 5 V microcontrollers without level-shifting circuitry. Its RDS(on) remains stable across junction temperatures up to 175 °C, supported by a low thermal resistance of 0.6 K/W from junction to mounting base.
The integrated source-drain diode exhibits fast recovery (trr = 70 ns, Qr = 67 nC) and low forward voltage (VSD = 0.85–1.2 V @ IS = 25 A), making it suitable for synchronous rectification and freewheeling in DC-DC converters. Avalanche energy rating (560 mJ) confirms robust unclamped inductive switching capability under defined test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 40 V - Maximum continuous drain-source blocking voltage; defines upper limit for DC bus voltage in motor control or UPS designs. |
| ID (DC) | 75 A @ Tmb = 25 °C, VGS = 10 V - Continuous current handling capacity when mounted on heatsink; derates with mounting base temperature per Figure 2. |
| RDS(on) | 3.6 mΩ (typ) @ VGS = 10 V, ID = 25 A, Tj = 25 °C - Low conduction loss enables high-efficiency power switching; rises to 7.6 mΩ at 175 °C junction. |
| VGS(th) | 1.0–2.0 V @ ID = 1 mA - Logic-level threshold ensures full enhancement with 3.3 V or 5 V gate drive; usable down to 0.5 V at 175 °C. |
| EAS | 560 mJ - Non-repetitive avalanche energy rating under unclamped inductive load (ID = 74 A, tp = 0.28 ms); supports reliable operation in inductive switching circuits. |
| Qg(tot) | 64 nC @ VDD = 32 V, VGS = 5 V - Total gate charge determines driver strength requirement; Miller charge (Qgd = 24 nC) impacts switching speed and EMI. |
| Rth(j-mb) | 0.6 K/W - Thermal resistance from silicon junction to mounting base; enables high-power dissipation with minimal ΔT when properly heatsinked. |
Pinout & Package
PHP174NQ04LT uses the TO-220AB (SOT78) plastic single-ended package with heatsink mounting and three leads. The mounting base (MB) is electrically connected to the drain terminal and serves as primary thermal path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Gate (G) | Control input; requires ≤±15 V gate-source voltage; logic-level compatible with 3.3 V/5 V controllers. |
| 2 | Drain (D) | Main power output terminal; internally connected to mounting base; must be isolated from PCB ground if heatsink is grounded. |
| 3 | Source (S) | Power return path and reference for gate drive; common node for low-side switching configuration. |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive | VGS(th) = 1–2 V enables direct interfacing with 3.3 V or 5 V microcontrollers, eliminating external level shifters in embedded motor control. |
| Ultra-low RDS(on) | 3.6 mΩ @ 10 V gate drive minimizes conduction losses in high-current paths, supporting >95% efficiency in 40 V DC-DC stages. |
| Avalanche-rated | 560 mJ non-repetitive avalanche energy allows safe operation during inductive turn-off transients without external snubbers in relay or solenoid drivers. |
| Fast-recovery body diode | trr = 70 ns and Qr = 67 nC support efficient freewheeling in synchronous buck converters and reduce reverse recovery losses. |
| Thermally optimized package | Rth(j-mb) = 0.6 K/W enables high-power dissipation with standard TO-220 heatsinks, simplifying thermal design for industrial power modules. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel logic-level power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP75NF40 | 40 V VDS, 75 A ID, but higher RDS(on) (6.5 mΩ typ @ 10 V); VGS(th) = 2–4 V - less logic-level tolerant. | Requires 10 V gate drive for optimal RDS(on); not recommended for 3.3 V controller interfaces without buffer. | Select STP75NF40 only when gate drive voltage ≥8 V is available and lower cost is prioritized over thermal performance. |
| IRF1404Z | 40 V VDS, 130 A ID, RDS(on) = 4.7 mΩ @ 10 V; VGS(th) = 2–4 V - higher threshold limits 3.3 V compatibility. | Better current headroom but slower switching (Qg = 131 nC) and no specified avalanche rating. | Prefer IRF1404Z for high-surge applications where gate drive ≥10 V is assured and avalanche robustness is secondary. |
Compared with STP75NF40 and IRF1404Z, PHP174NQ04LT delivers superior logic-level drive margin (1–2 V threshold), lower conduction loss (3.6 mΩ), and verified avalanche ruggedness (560 mJ), making it the preferred choice for space-constrained, thermally demanding, and microcontroller-driven power switching.

FAQ
What is the maximum continuous drain current rating for PHP174NQ04LT?
The PHP174NQ04LT is rated for 75 A continuous drain current (ID) at Tmb = 25 °C and VGS = 10 V. This rating decreases with increasing mounting base temperature per the derating curve in Figure 2 of the datasheet. At Tmb = 100 °C, the device still supports 75 A, confirming robust thermal design for forced-air or heatsink-cooled applications.
Is PHP174NQ04LT compatible with 3.3 V microcontroller GPIO outputs?
Yes, PHP174NQ04LT is fully compatible with 3.3 V logic-level drive due to its VGS(th) range of 1.0–2.0 V at 25 °C and guaranteed minimum of 0.5 V at 175 °C. At VGS = 4.5 V, RDS(on) remains ≤4.8 mΩ, ensuring low conduction loss without external level shifting - a key advantage over higher-threshold alternatives like IRF1404Z.
What is the thermal resistance from junction to mounting base for PHP174NQ04LT?
The PHP174NQ04LT has a maximum thermal resistance of Rth(j-mb) = 0.6 K/W from junction to mounting base, as specified in Table 4. This low value enables efficient heat transfer to an external heatsink, allowing the device to sustain 250 W total power dissipation at Tmb = 25 °C while maintaining safe junction temperatures.
Does PHP174NQ04LT include avalanche energy rating information?
Yes, PHP174NQ04LT specifies a non-repetitive drain-source avalanche energy (EAS) of 560 mJ under defined test conditions: unclamped inductive load, ID = 74 A, tp = 0.28 ms, VDD ≤40 V, RGS = 50 Ω, VGS = 10 V, and starting Tj = 25 °C. This rating validates its suitability for inductive switching without snubber networks.
What package type is used for PHP174NQ04LT?
PHP174NQ04LT is supplied in the TO-220AB plastic single-ended package (SOT78), featuring three leads and a metal mounting base electrically connected to the drain. The package includes one mounting hole and is designed for heatsink attachment, with standardized dimensions compliant with JEDEC SC-46 outlines.
