Product details
Overview
TPH11003NL,LQ from Toshiba is a silicon N-channel power MOSFET in U-MOSⅧ-H process, designed for high-efficiency DC-DC converters and synchronous rectification. It delivers RDS(ON) = 12.6 mΩ (typ.) at VGS = 4.5 V, QSW = 2.0 nC (typ.), and supports continuous drain current up to 32 A with 30 V VDSS, enabling compact, high-frequency switching power stages.
For engineers reviewing the TPH11003NL,LQ datasheet, TPH11003NL,LQ pinout, TPH11003NL,LQ application, or TPH11003NL,LQ equivalent, key selection criteria include low gate charge for fast turn-on/turn-off, tight Vth range (1.3–2.3 V), robust avalanche rating (EAS = 29 mJ), and thermal performance on standard PCB layouts.
Technical Context
This MOSFET employs Toshiba's U-MOSⅧ-H trench-gate structure to minimize conduction and switching losses simultaneously. Its low RDS(ON) and optimized Ciss/Crss ratio (510 pF / 18 pF typ.) support high-frequency operation in buck converters and OR-ing circuits.
The device operates in enhancement mode with guaranteed Vth between 1.3 V and 2.3 V, ensuring reliable gate drive compatibility with 3.3 V and 5 V logic controllers. Its 8-pin SOP Advance package provides dual-side cooling capability via exposed drain pads (pins 5–8) and integrated source terminals (pins 1–3).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30 V - Maximum blocking voltage for 12 V input rail applications with margin |
| RDS(ON) @ 4.5 V | 12.6 mΩ (typ.) - Enables <1 W conduction loss at 10 A in compact 5 V-output converters |
| QSW | 2.0 nC (typ.) - Reduces switching energy loss and gate driver power requirement |
| ID (DC) | 32 A - Supports high-current POL stages without external heatsinking on 2-layer boards |
| EAS | 29 mJ - Withstands single-pulse inductive energy during hard-switching transitions |
| Ciss | 510 pF (typ.) - Low input capacitance minimizes Miller effect and improves dv/dt immunity |
| Tch max | 150 °C - Specifies maximum junction temperature for derated power handling |
Pinout & Package
TPH11003NL,LQ uses the 8-pin SOP Advance (TOSHIBA: 2-5Q1S) surface-mount package with exposed drain thermal pad. The package enables efficient heat transfer through both top-side (drain pins) and bottom-side (exposed pad) paths, supporting >2 W dissipation on standard FR-4 PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Source | Common source connection for internal parallel FET cells; low-inductance return path |
| 4 | Gate | Control terminal requiring ≤2.3 V threshold; sensitive to ESD (handle per JESD22-A114) |
| 5, 6, 7, 8 | Drain | Parallel-connected drain terminals tied to exposed thermal pad; primary heat extraction path |
Key Features

| Low QSW/RDS(ON) ratio | Optimizes trade-off between switching speed and conduction loss in 500 kHz–2 MHz converters |
| Enhancement-mode Vth | 1.3–2.3 V range ensures turn-on with standard microcontroller GPIOs without level-shifting |
| Low IDSS | ≤10 µA at 30 V enables stable standby operation in always-on power domains |

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 |
|---|---|---|---|
| SiR872DP-T1-GE3 | RDS(ON) = 11.5 mΩ @ 4.5 V; higher Qg = 12.5 nC; PowerPAK SO-8 package | Better conduction loss but slower switching; suited for lower-frequency (<300 kHz) designs | Select when thermal budget dominates over switching loss, e.g., in fan-cooled industrial supplies |
| IRLHS6342TRPBF | RDS(ON) = 13.5 mΩ @ 4.5 V; QSW = 1.8 nC; 6-pin TSOP-6 package with smaller footprint | Lower current rating (16 A DC); limited avalanche energy (12 mJ); no exposed drain pad | Choose for space-constrained consumer adapters where peak current ≤12 A and layout area is critical |
Compared with SiR872DP-T1-GE3 and IRLHS6342TRPBF, the TPH11003NL,LQ offers superior balance of low QSW and moderate RDS(ON) in an 8-pin thermally enhanced package-ideal for high-frequency, medium-power DC-DC stages where both efficiency and board-level thermal management matter.

FAQ
What is the gate threshold voltage range for TPH11003NL,LQ?
The TPH11003NL,LQ has a guaranteed gate threshold voltage (Vth) range of 1.3 V to 2.3 V at VDS = 10 V and ID = 0.1 mA. This enhancement-mode specification ensures reliable turn-on with standard 3.3 V microcontroller outputs and eliminates need for gate boosting in many low-voltage control applications. The narrow Vth distribution also improves consistency across parallel configurations in multiphase designs.
Does TPH11003NL,LQ support synchronous rectification in buck converters?
Yes, the TPH11003NL,LQ is explicitly qualified for synchronous rectification due to its low RDS(ON) (12.6 mΩ typ. at 4.5 V), fast switching (QSW = 2.0 nC typ.), and robust body diode (VDSF = −1.2 V typ. at 11 A). Its 8-pin SOP Advance package provides low-inductance source and drain paths essential for minimizing shoot-through risk and optimizing dead-time control in high-frequency buck stages.
What is the maximum continuous drain current for TPH11003NL,LQ at 100 °C case temperature?
At Tc = 100 °C, the TPH11003NL,LQ supports a derated continuous drain current of approximately 22 A, calculated using its absolute maximum ID = 32 A at Tc = 25 °C and Rth(ch-c) = 5.95 °C/W. This derating follows standard thermal modeling and assumes proper PCB copper area (≥10 cm² 2-oz copper) under the exposed drain pad to maintain channel temperature ≤150 °C.
Is TPH11003NL,LQ RoHS compliant and halogen-free?
Yes, the TPH11003NL,LQ meets RoHS Directive 2011/65/EU requirements and is halogen-free per JEDEC JS709B. Toshiba confirms compliance in its official product change notices and material declarations. Full substance data and certificate of compliance are available upon request from Aetrix Electronics for qualifying production lots.
Can TPH11003NL,LQ be used in avalanche-mode operation?
Yes, the TPH11003NL,LQ is rated for single-pulse avalanche energy (EAS) of 29 mJ at Tch = 25 °C, with guaranteed IAR = 11 A. This rating applies under defined test conditions (VDD = 24 V, L = 190 µH) and supports limited unclamped inductive switching-such as in certain flyback snubberless designs-but does not imply repetitive avalanche capability. Designers must verify stress margins per application.
