Product details
Overview
PHP143NQ04T from NXP Semiconductors (formerly Philips) is an N-channel TrenchMOS™ standard-level power MOSFET in TO-220AB (SOT78) package, rated for 40 V VDS, 75 A continuous drain current at Tmb = 25 °C, and 5.2 mΩ RDS(on) at VGS = 10 V - deployed in high-current DC-to-DC converters and motor drive stages.
For engineers reviewing the PHP143NQ04T datasheet, PHP143NQ04T pinout, PHP143NQ04T application, or PHP143NQ04T equivalent, key selection criteria include its low on-resistance, avalanche ruggedness (475 mJ), thermal resistance to mounting base (0.75 K/W), and compatibility with standard-level gate drive (VGS(th) = 2–4 V).
Technical Context
This device uses TrenchMOS™ technology to achieve low RDS(on) and high current capability in a thermally optimized TO-220AB package. Its standard-level gate threshold (2–4 V) enables direct interfacing with 5 V logic and microcontroller GPIOs without level-shifting circuitry.
The integrated source-drain diode supports synchronous rectification and freewheeling in buck converters and H-bridge motor drivers. Avalanche energy rating of 475 mJ ensures robustness under inductive switching transients common in solenoid and lamp control applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 40 V - Maximum blocking voltage compatible with 36 V nominal battery and 48 V industrial bus systems. |
| ID (continuous) | 75 A at Tmb = 25 °C - Supports high-power loads such as 1 kW DC motors or multi-phase converter legs. |
| RDS(on) | 4.4–5.2 mΩ at VGS = 10 V - Enables <1 W conduction loss at 20 A, critical for thermal management in compact designs. |
| Qg(tot) | 52 nC - Determines gate driver power requirement and switching speed in hard-switched topologies. |
| EAS | 475 mJ - Specifies unclamped inductive switching capability, enabling reliable operation in relay/solenoid snubberless circuits. |
| Rth(j-mb) | 0.75 K/W - Directly defines junction-to-heatsink thermal drop; allows accurate junction temperature estimation under load. |
Pinout & Package
PHP143NQ04T is housed in a TO-220AB (SOT78) plastic single-ended package with heatsink-mounted construction, 1 mounting hole, and 3 leads. The mounting base (MB) is electrically connected to the drain terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Gate (G) | Control input; requires 10 V drive for full enhancement; threshold range 2–4 V enables TTL/CMOS compatibility. |
| 2 | Drain (D) | Main power output node; internally bonded to mounting base - must be isolated from PCB ground unless drain-referenced topology. |
| 3 | Source (S) | Power return path and reference for gate drive; connects to system ground or low-side switch node. |
Key Features
| Feature | Design Value |
|---|---|
| TrenchMOS™ technology | Delivers 5.2 mΩ RDS(on) in TO-220AB, reducing conduction losses vs. planar MOSFETs of same footprint. |
| Standard-level gate drive | 2–4 V VGS(th) allows direct connection to 3.3 V/5 V MCUs without gate driver ICs in low-frequency switching. |
| Avalanche-rated | 475 mJ EAS supports reliable operation in inductive load switching without external clamping diodes. |
| Low thermal resistance | 0.75 K/W Rth(j-mb) enables >100 W dissipation with modest heatsinking - suitable for space-constrained industrial modules. |
Applications
| Motor Drive Stage | DC-to-DC Converter Primary Switch |
|---|---|
Use Scenario: High-current brushed DC motor control in industrial actuators and HVAC blowers. IC Role / Device Role / Timing Role: Low-side or half-bridge N-channel switch handling up to 75 A peak current during stall conditions.

IC Role / Device Role / Timing Role: Main power switch operating at 100–250 kHz with unclamped inductive turn-off stress. Use Value: 475 mJ avalanche energy rating absorbs leakage inductance spikes without failure during transient overload. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP75NF40 | 40 V VDS, 75 A ID, 5.5 mΩ RDS(on), TO-220 package; higher Qg (95 nC) than PHP143NQ04T. | Higher gate charge increases driver loss and slows switching - less optimal for >100 kHz SMPS. | Select when legacy STMicro design reuse is required; verify gate drive strength due to higher Qg. |
| IRF1404 | 40 V VDS, 169 A ID (pulsed), 4.7 mΩ RDS(on), TO-220; no published EAS rating. | Lacks specified avalanche ruggedness - unsuitable for unclamped inductive loads without external protection. | Prefer for pure low-RDS(on) DC switching where avalanche stress is absent; avoid in solenoid/motor freewheeling. |
Compared with STP75NF40 and IRF1404, PHP143NQ04T offers balanced performance: lower Qg than STP75NF40 for faster switching efficiency, and certified avalanche ruggedness absent in IRF1404 - making it uniquely suited for industrial inductive load control with minimal external protection.

FAQ
What is the maximum continuous drain current rating for PHP143NQ04T?
The PHP143NQ04T is rated for 75 A continuous drain current at mounting base temperature (Tmb) = 25 °C with VGS = 10 V. Derating applies above 25 °C - e.g., 75 A remains valid up to Tmb = 100 °C per Figure 2 in the datasheet. This rating assumes proper heatsinking and thermal interface to maintain Tj ≤ 175 °C.
Does PHP143NQ04T support gate drive from a 3.3 V microcontroller?
No - PHP143NQ04T has a gate threshold voltage (VGS(th)) of 2–4 V, but full enhancement requires VGS ≥ 10 V to achieve its specified 5.2 mΩ RDS(on). A 3.3 V MCU output cannot fully turn on PHP143NQ04T, resulting in high conduction loss and thermal risk. A gate driver or level shifter is required for reliable operation.
What is the avalanche energy rating of PHP143NQ04T and how is it applied?
PHP143NQ04T is rated for 475 mJ non-repetitive drain-source avalanche energy (EDS(AL)S) under defined test conditions: unclamped inductive load, ID = 69 A, tp = 0.27 ms, VDD ≤ 40 V, RGS = 50 Ω, VGS = 10 V, starting at Tj = 25 °C. This rating validates safe operation during inductive turn-off transients in motor and solenoid drivers without external snubbers.
Is PHP143NQ04T pin-compatible with PHB143NQ04T?
No - PHP143NQ04T uses the TO-220AB (SOT78) package, while PHB143NQ04T uses the D2-PAK (SOT404) surface-mount package. Though electrically identical, their footprints, thermal paths, and mounting methods differ significantly. PCB layout and mechanical assembly must be redesigned when substituting between them.
What is the thermal resistance from junction to mounting base for PHP143NQ04T?
The maximum thermal resistance from junction to mounting base (Rth(j-mb)) for PHP143NQ04T is 0.75 K/W, per Table 4 in the datasheet. This value enables precise junction temperature calculation using Tj = Tmb + (Pdiss × Rth(j-mb)), critical for reliability validation in high-power industrial applications.
