Product details
Overview
PHP129NQ04LT from NXP Semiconductors (formerly Philips Semiconductors) is a logic-level N-channel TrenchMOS™ power MOSFET in TO-220AB (SOT78) package, rated for 40 V VDS, 75 A ID, and 200 W Ptot, with RDS(on) ≤ 5 mΩ at VGS = 10 V - designed for high-current DC switching in motor drives and industrial power supplies.
For engineers reviewing the PHP129NQ04LT datasheet, PHP129NQ04LT pinout, PHP129NQ04LT application, or PHP129NQ04LT equivalent, key selection criteria include logic-level gate drive compatibility (VGS(th) = 1–2 V), low on-resistance under thermal stress, avalanche ruggedness (475 mJ), and mounting-base thermal resistance (0.75 K/W).
Technical Context
This device uses TrenchMOS™ technology to achieve enhanced conduction efficiency and fast switching dynamics. Its gate threshold voltage (1–2 V at Tj = 25 °C) enables direct interface with 3.3 V/5 V logic controllers without level-shifting circuitry.
The SOT78 (TO-220AB) package features an electrically connected mounting base tied to the drain, supporting heatsink-integrated thermal management. It delivers 240 A peak drain current (IDM) and exhibits robust unclamped inductive avalanche capability (EDS(AL)S = 475 mJ) under defined test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 40 V maximum drain-source voltage - supports 36 V nominal bus systems with 10 % margin. |
| ID | 75 A continuous drain current at Tmb = 25 °C - enables high-power load switching without forced air cooling. |
| RDS(on) | 4.1–5 mΩ at VGS = 10 V, Tj = 25 °C - reduces conduction loss to <1.2 W at 25 A, improving thermal headroom. |
| VGS(th) | 1–2 V threshold voltage - ensures full enhancement with standard 3.3 V or 5 V microcontroller GPIOs. |
| EDS(AL)S | 475 mJ non-repetitive avalanche energy - withstands inductive kickback in relay/motor control without external snubbers. |
| Rth(j-mb) | 0.75 K/W junction-to-mounting-base thermal resistance - allows efficient heat transfer to external heatsinks. |
| Qg(tot) | 44.2 nC total gate charge - determines driver strength requirement for <100 ns switching transitions at 25 A. |
Pinout & Package
Package: TO-220AB (SOT78), plastic single-ended package with heatsink-mounted mounting base and 3 leads. Mounting base is electrically connected to drain terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Gate (G) | Control input; requires ≤±15 V gate-source voltage; low input capacitance (Ciss = 3965 pF) eases driver design. |
| 2 | Drain (D) | High-side power output node; internally bonded to mounting base - must be isolated from heatsink unless referenced to same potential. |
| 3 | Source (S) | Power return path and reference for gate drive; forms common node with load ground in low-side switch configuration. |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive | VGS(th) = 1–2 V enables direct interfacing with 3.3 V/5 V MCUs, eliminating level-shifters and reducing BOM count. |
| Ultra-low RDS(on) | 4.1 mΩ typical at 10 V gate drive minimizes I²R losses in high-current paths, critical for thermal stability in enclosed enclosures. |
| Avalanche-rated | 475 mJ unclamped inductive avalanche energy provides inherent protection against inductive transients in motor/solenoid loads. |
| TrenchMOS™ technology | Enables higher cell density and lower specific on-resistance versus planar MOSFETs, improving power density in space-constrained designs. |
| Mounting-base thermal path | 0.75 K/W Rth(j-mb) enables >150 W dissipation with modest heatsinking - suitable for industrial-grade continuous operation. |
Applications
| Motor Control Systems | Uninterruptible Power Supplies (UPS) |

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 |
|---|---|---|---|
| STP75NF75 | 75 V VDS, 75 A ID, RDS(on) = 12.5 mΩ @ 10 V - higher voltage rating but double the on-resistance. | Better suited for 48 V systems; less efficient at 24–36 V due to higher conduction loss. | Select when system bus voltage exceeds 40 V or when higher avalanche margin is required despite efficiency trade-off. |
| IRF1404ZPBF | 40 V VDS, 130 A ID, RDS(on) = 4.7 mΩ @ 10 V - higher current rating and similar on-resistance, but VGS(th) = 2–4 V. | Requires stronger gate drive for full enhancement; not guaranteed logic-level compatible at 3.3 V. | Prefer when peak current > 75 A is needed and gate drive can supply ≥4.5 V; verify VGS(th) distribution across temperature. |
Compared with STP75NF75 and IRF1404ZPBF, PHP129NQ04LT uniquely balances logic-level drivability (1–2 V threshold), ultra-low RDS(on) (≤5 mΩ), and proven 475 mJ avalanche energy - making it optimal for thermally constrained 24–36 V industrial switching where gate drive simplicity and transient robustness are prioritized.

FAQ
What is the gate-source threshold voltage range for PHP129NQ04LT?
The PHP129NQ04LT has a gate-source threshold voltage (VGS(th)) of 1–2 V at Tj = 25 °C, dropping to 0.5 V minimum at 175 °C and rising to 2.2 V maximum at −55 °C. This logic-level range ensures reliable turn-on with standard 3.3 V or 5 V microcontroller outputs across its full operating temperature range.
Is PHP129NQ04LT suitable for high-frequency switching applications?
Yes - PHP129NQ04LT supports high-frequency operation with td(on) = 43 ns, tr = 145 ns, td(off) = 132 ns, and tf = 92 ns under standard test conditions. Its 44.2 nC total gate charge and 3965 pF input capacitance enable efficient switching up to ~200 kHz in hard-switched topologies when paired with appropriately sized gate drivers.
Does PHP129NQ04LT have an integrated body diode, and what are its characteristics?
Yes - PHP129NQ04LT includes an integrated source-drain body diode rated for 75 A DC forward current (IS) and 240 A peak (ISM). Its forward voltage is 0.85–1.2 V at IS = 25 A and VGS = 0 V, with reverse recovery time (trr) = 61 ns and recovered charge (Qr) = 57 nC - suitable for freewheeling in inductive loads without external diodes.
What is the thermal resistance from junction to mounting base for PHP129NQ04LT?
The PHP129NQ04LT has a maximum thermal resistance of Rth(j-mb) = 0.75 K/W from junction to mounting base. This value is measured under specified test conditions and enables effective heat transfer to externally mounted heatsinks - critical for sustaining 200 W total power dissipation in industrial environments.
Can PHP129NQ04LT be used in avalanche mode, and what is its rated energy?
Yes - PHP129NQ04LT is rated for non-repetitive unclamped inductive avalanche with EDS(AL)S = 475 mJ under defined conditions (ID = 69 A, tp = 0.27 ms, VDD ≤ 40 V, RGS = 50 Ω, VGS = 10 V, starting Tj = 25 °C). This specification validates its robustness in motor commutation and relay driving where inductive spikes occur.
