Product details
Overview
PHP9NQ20T,127 from Nexperia is a standard-level N-channel TrenchMOS FET in TO-220AB (SOT78) package, designed for high-efficiency switching in power conversion stages. It delivers 200 V VDS, 8.7 A continuous drain current at Tmb = 25 °C, and 300–400 mΩ RDS(on) at VGS = 10 V and Tj = 25 °C, enabling use in off-line SMPS and DC-DC converters.
For engineers reviewing the PHP9NQ20T,127 datasheet, PHP9NQ20T,127 pinout, PHP9NQ20T,127 application, or PHP9NQ20T,127 equivalent, key selection criteria include thermal resistance (Rth(j-mb) = 1.7 K/W), fast switching (tr = 19 ns, tf = 15 ns), avalanche ruggedness (EAS = 93 mJ), and gate charge (QGD = 12 nC).
Technical Context
This device employs TrenchMOS technology to achieve low conduction losses and high thermal efficiency. Its mounting base (tab) is internally connected to the drain, enabling direct heatsink coupling and minimizing thermal path resistance - critical for sustained 88 W power dissipation at Tmb = 25 °C.
The FET features a gate threshold voltage of 2–4 V at 25 °C and maintains stable operation up to Tj = 175 °C. Its dynamic characteristics - including Ciss = 959 pF, Coss = 93 pF, and Crss = 54 pF - support high-frequency switching in hard-switched topologies without excessive drive loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 200 V - supports primary-side switching in universal-input off-line SMPS up to 265 VAC. |
| ID (continuous) | 8.7 A at Tmb = 25 °C - enables medium-power DC-DC stages with minimal parallel devices. |
| RDS(on) | 300–400 mΩ at VGS = 10 V, ID = 4.5 A, Tj = 25 °C - reduces conduction loss in 12–48 V output converters. |
| QGD | 12 nC - limits Miller-induced switching delay and improves controllability in high-dV/dt environments. |
| Rth(j-mb) | 1.7 K/W - allows efficient heat transfer to external heatsink, supporting >70 W continuous operation with modest cooling. |
| tr/tf | 19 ns / 15 ns - enables operation above 200 kHz in hard-switched topologies with low switching loss. |
| EAS | 93 mJ - provides unclamped inductive avalanche capability for robustness in motor control and relay driving. |
Pinout & Package
Package: TO-220AB (SOT78), plastic single-ended package with heatsink-mountable metal tab (drain-connected), 3 leads, and one mounting hole. Mounting base serves as both mechanical anchor and primary thermal interface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G) | Gate | Controls channel conduction; requires 10 V drive for full enhancement; threshold 2–4 V ensures TTL/CMOS compatibility. |
| 2 (D) | Drain | High-voltage power input node; electrically tied to mounting base for low-inductance, low-thermal-resistance heatsinking. |
| 3 (S) | Source | Power return path and reference for gate drive; internal source bond pad inductance is 7.5 nH - impacts high-speed layout. |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(on) | 300–400 mΩ at 10 V drive - directly reduces I²R conduction loss in 5–10 A load ranges. |
| TrenchMOS architecture | Enables higher cell density and lower gate charge vs planar MOSFETs - improves switching efficiency at 100–500 kHz. |
| Drain-connected mounting base | Eliminates need for insulating washer while maintaining thermal performance - simplifies heatsink integration and lowers assembly cost. |
| Avalanche-rated | 93 mJ non-repetitive EAS - withstands inductive turn-off transients in motor drives and solenoid controls without external snubbers. |
| Fast switching | tr = 19 ns, tf = 15 ns - minimizes overlap loss during PWM transitions in synchronous rectifiers and half-bridges. |
Applications
| DC-DC Converters | Off-line SMPS |

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 |
|---|---|---|---|
| STP9NK20ZFP | Zener-protected avalanche rating (EAS = 120 mJ); higher RDS(on) (450 mΩ typ); TO-220FP package (no drain-tab exposure). | Better surge immunity but requires insulating pad; less thermally efficient due to plastic isolation. | Prefer when enhanced overvoltage robustness is prioritized over thermal performance. |
| IRF640NPBF | Higher VDS (200 V same), but higher RDS(on) (180 mΩ min at 10 V, but 250 mΩ typical at 25 °C); slower switching (tr = 55 ns). | Lower conduction loss only at elevated VGS; unsuitable for >100 kHz due to higher QG and Coss. | Choose only for legacy designs where gate drive voltage exceeds 12 V and frequency <80 kHz. |
Compared with STP9NK20ZFP and IRF640NPBF, PHP9NQ20T,127 offers superior thermal management via drain-connected tab, tighter RDS(on) distribution, and faster switching - making it optimal for compact, high-efficiency, medium-frequency power stages where heatsink access is available.

FAQ
Is PHP9NQ20T,127 suitable for automotive applications?
No. The PHP9NQ20T,127 is not AEC-Q101 qualified and is explicitly rated for computing, communications, consumer, and industrial use only. It lacks automotive-grade screening, extended temperature validation beyond −55 °C to +175 °C junction, and zero-defect manufacturing controls required for automotive systems.
What is the maximum safe gate-source voltage for continuous operation?
The absolute maximum VGS is ±30 V, but for reliable long-term operation, Nexperia specifies a recommended maximum of ±20 V. Exceeding ±20 V risks gate oxide degradation, especially at elevated temperatures or with transient overshoots from PCB trace inductance.
Can the mounting base be electrically isolated from the heatsink?
No - the mounting base is internally connected to the drain terminal. Electrical isolation requires an insulated mounting kit (e.g., silicone pad + shoulder washer), which increases Rth(j-mb) by ≥0.5 K/W and must be accounted for in thermal design.
Does PHP9NQ20T,127 include integrated gate protection?
No. This device has no built-in gate protection diode or Zener clamp. External gate resistors (≥5.6 Ω) and TVS diodes (e.g., P6KE15A) between gate and source are required to suppress ESD and dv/dt-induced gate ringing in real-world layouts.
