Product details
Overview
TK33S10N1L,LXHQ from Toshiba Electronic Devices & Storage Corporation is an AEC-Q101-qualified silicon N-channel power MOSFET in U-MOSⅧ-H process, designed for high-current automotive switching. It delivers 33 A DC drain current, 8.2 mΩ RDS(ON) at VGS = 10 V, and 100 V drain-source breakdown voltage, operating reliably up to 175 °C channel temperature in motor drivers and DC-DC regulators.
For engineers reviewing the TK33S10N1L,LXHQ datasheet, TK33S10N1L,LXHQ pinout, TK33S10N1L,LXHQ application, or TK33S10N1L,LXHQ equivalent, this page provides verified electrical specs, thermal limits, gate charge data, avalanche ruggedness (101 mJ), and DPAK+ package terminal mapping - all critical for automotive-grade layout, SOA validation, and thermal design.
Technical Context
This MOSFET uses Toshiba's U-MOSⅧ-H trench-gate structure to achieve low on-resistance and fast switching with controlled Qgd/Qg ratio (8/33 nC). Its enhancement-mode threshold (1.5–2.5 V) enables direct 3.3 V/5 V logic-level drive compatibility when paired with appropriate gate resistors.
The device integrates a robust body diode with 66 ns reverse recovery time and 60 nC Qrr, supporting synchronous rectification and freewheeling in hard-switched topologies. Its 8.4 V/ns dVDS/dt rating and guaranteed single-pulse avalanche energy (101 mJ) support reliable operation under inductive load transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 100 V - supports 48 V automotive systems with ≥2× safety margin against load-dump transients |
| RDS(ON) (typ.) | 8.2 mΩ at VGS = 10 V - enables <1 W conduction loss at 33 A, reducing heatsink requirements |
| ID (DC) | 33 A at Tc = 25 °C - rated for continuous high-current operation with proper heatsinking |
| EAS | 101 mJ - withstands inductive energy spikes without failure in motor control or SMPS freewheeling |
| Rth(ch-c) | 1.2 °C/W - allows precise junction-to-heatsink thermal modeling for automotive under-hood environments |
| Qg | 33 nC - determines gate driver power and switching loss; compatible with standard 1-A peak drivers |
| Vth | 1.5–2.5 V - ensures turn-on with 3.3 V microcontrollers while avoiding false triggering from noise |
Pinout & Package
TK33S10N1L,LXHQ is housed in a surface-mount DPAK+ (TOSHIBA 2-7M1A) package with exposed drain pad for thermal and electrical connection to PCB heatsink. The package weighs 0.36 g and features RoHS-compliant plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Gate (G) | Control input; requires ESD-safe handling and ≤25 Ω series resistance to limit ringing and overshoot |
| 2 | Drain (D) | Main power output node; electrically and thermally connected to exposed copper pad for low-inductance, high-current path |
| 3 | Source (S) | Power return reference; ties to ground plane; establishes VGS control voltage relative to load current path |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control, ADAS actuators, and body electronics per stress test requirements |
| Low RDS(ON) × Qg figure-of-merit | 270 mΩ·nC - balances conduction and switching losses for high-efficiency 100 kHz–500 kHz DC-DC converters |
| High dVDS/dt ruggedness | 8.4 V/ns - prevents spurious turn-on during fast voltage transitions in half-bridge configurations |
| Robust body diode | 66 ns trr, 60 nC Qrr - reduces voltage spikes and EMI in inductive switching, enabling simpler snubber design |
| 175 °C maximum channel temperature | Supports operation in under-hood environments (e.g., EPS, HVAC blowers) without derating at full current |

FAQ
What is the maximum continuous drain current rating for TK33S10N1L,LXHQ?
The TK33S10N1L,LXHQ is rated for 33 A DC drain current at case temperature Tc = 25 °C. At higher case temperatures, current must be derated per the Safe Operating Area curve in the datasheet; at Tc = 100 °C, the practical limit drops to approximately 22 A to maintain channel temperature ≤175 °C.
Is TK33S10N1L,LXHQ suitable for 48 V mild-hybrid automotive systems?
Yes, TK33S10N1L,LXHQ is explicitly designed for 48 V automotive applications. Its 100 V VDSS rating provides >2× margin over nominal 48 V bus, and its AEC-Q101 qualification covers temperature cycling, humidity, and mechanical shock tests required for mild-hybrid powertrain modules.
Does TK33S10N1L,LXHQ have a built-in body diode, and what are its key parameters?
Yes, TK33S10N1L,LXHQ integrates a fast-recovery body diode characterized at 33 A reverse current: typical reverse recovery time (trr) is 66 ns and reverse recovery charge (Qrr) is 60 nC. These values enable efficient freewheeling in synchronous buck and half-bridge topologies without external diodes.
What gate drive voltage is recommended for optimal RDS(ON) performance of TK33S10N1L,LXHQ?
TK33S10N1L,LXHQ achieves its specified 8.2 mΩ RDS(ON) at VGS = 10 V. For full enhancement with margin, a 12 V gate drive is recommended. It remains fully enhanced down to VGS = 4.5 V (RDS(ON) ≤ 16.2 mΩ), enabling compatibility with 5 V logic and certain 3.3 V controllers using level-shifting.
How does the DPAK+ package of TK33S10N1L,LXHQ improve thermal performance over standard DPAK?
The DPAK+ (TOSHIBA 2-7M1A) package used by TK33S10N1L,LXHQ features an enlarged exposed drain pad and optimized internal leadframe geometry, achieving 1.2 °C/W channel-to-case thermal resistance - 15% lower than standard DPAK. This directly improves power dissipation capability and reduces PCB heatsink area requirements.
