Product details
Overview
SPI100N03S2L-03 from Infineon Technologies is an N-channel enhancement-mode logic-level power MOSFET in TO262-3-1 package, rated for 30 V VDS, 100 A continuous drain current at TC = 25 °C, and 2.7 mΩ max RDS(on) at VGS = 4.5 V. It operates up to 175 °C, features avalanche rating, dv/dt ruggedness (6 kV/µs), and is optimized for high-efficiency DC-DC converters and motor control in industrial power supplies.
For engineers reviewing the SPI100N03S2L-03 datasheet, SPI100N03S2L-03 pinout, SPI100N03S2L-03 application, or SPI100N03S2L-03 equivalent, key selection criteria include its low gate charge × RDS(on) figure of merit (FOM), superior thermal resistance (RthJC = 0.3–0.5 K/W), and robust unclamped inductive switching capability.
Technical Context
This OptiMOS™ device uses trench-gate silicon technology to achieve high current density with low conduction and switching losses. Its logic-level gate drive (VGS(th) = 1.2–2.0 V) enables direct interfacing with 3.3 V and 5 V microcontrollers without level-shifting circuitry.
The MOSFET integrates a fast, soft-recovery body diode (trr = 86–108 ns, Qrr = 100–125 nC) and supports repetitive avalanche operation (EAR = 30 mJ), making it suitable for hard-switched topologies where diode reverse recovery stress is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 30 V - Maximum blocking voltage for 12 V and 24 V system-level bus protection and switching |
| RDS(on) max @ VGS = 4.5 V | 3.4 mΩ - Enables <1 W conduction loss at 80 A, critical for high-current synchronous rectification |
| ID continuous @ TC = 25 °C | 100 A - Supports high-power motor drives and server VRMs without parallel devices |
| Qg total | 220 nC - Low gate charge reduces driver power demand and improves efficiency in 100–500 kHz switching |
| RthJC | 0.5 K/W max - Enables >240 W dissipation with modest heatsinking, reducing thermal margin risk |
| EAS | 810 mJ - Withstands single-pulse inductive energy in UPS and power tool H-bridge fault conditions |
| tr/tf | 67/65 ns - Fast switching minimizes overlap loss in half-bridge configurations at ≥200 kHz |
Pinout & Package
Package: TO262-3-1 (ISOTOP® variant of TO-220 compatible outline, surface-mountable with isolated tab). Thermal pad soldered to PCB copper for enhanced heat transfer.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (Tab) | Main current path output / heat sink interface | Electrically connected to exposed metal tab; must be electrically isolated from chassis unless system ground referenced |
| Source | Reference node for gate drive and current sensing | Low-inductance connection required for stable gate control and accurate shunt-based current monitoring |
| Gate | Control terminal for channel modulation | High-impedance input requiring <10 Ω series resistance to damp ringing and prevent oscillation during fast edge transitions |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate threshold | VGS(th) = 1.2–2.0 V ensures reliable turn-on with 3.3 V MCU GPIOs without gate driver IC overhead |
| Avalanche-rated operation | Single-pulse EAS = 810 mJ allows safe operation under inductive load switching faults without external snubbers |
| dv/dt ruggedness | 6 kV/µs rating prevents false turn-on during high-speed commutation in noisy motor drive environments |
| Soft-recovery body diode | Qrr = 100–125 nC and trr = 86–108 ns reduce voltage overshoot and EMI in freewheeling paths |
| 175 °C maximum junction temperature | Enables compact thermal design in sealed enclosures or high-ambient industrial settings without derating penalties |

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 |
|---|---|---|---|
| IRF1405PbF | RDS(on) = 5.3 mΩ @ 10 V (vs. 2.2 mΩ), higher Qg = 230 nC, TO-220 package only | Limited to lower-frequency (<100 kHz) applications due to slower switching and higher conduction loss | Prefer when cost sensitivity outweighs efficiency targets and thermal constraints are relaxed |
| STL110N3LLH6 | 30 V, RDS(on) = 2.3 mΩ @ 4.5 V, but rated only to 150 °C Tjmax and lacks avalanche rating | Not suitable for unclamped inductive loads or high-temperature sealed environments | Select only for space-constrained SMD designs where avalanche immunity is not required |
Compared with IRF1405PbF and STL110N3LLH6, SPI100N03S2L-03 delivers superior thermal capability (175 °C), proven avalanche robustness, and lowest gate-charge × RDS(on) FOM-making it the optimal choice for high-reliability, high-efficiency industrial power stages.

FAQ
What is the maximum recommended gate-source voltage for SPI100N03S2L-03?
The absolute maximum VGS is ±20 V per datasheet specifications. For reliable long-term operation, gate drive should be limited to +10 V to +15 V for full enhancement, with transient spikes held below +18 V using clamping Zener diodes or gate driver rail regulation.
Can SPI100N03S2L-03 be used in paralleled configurations?
Yes-the device exhibits positive temperature coefficient for RDS(on) above 100 °C, enabling inherently stable current sharing. Designers must match gate loop inductance and use Kelvin source connections to avoid oscillation and ensure balanced dynamic current distribution.
Is the body diode suitable for synchronous rectification?
No-the internal body diode is optimized for freewheeling, not synchronous rectification. Its Qrr and forward voltage are higher than discrete Schottky diodes. For synchronous rectifier applications, use external low-VF diodes or dedicated SR controllers with separate MOSFETs.
What PCB layout practices improve thermal performance?
Use ≥6 cm² of 70 µm thick copper on the drain pad, connected via multiple thermal vias to inner-layer ground planes. Avoid routing signal traces under the tab. Maintain ≥1.5 mm clearance between tab and adjacent components to prevent thermal coupling and ensure conformal coating compatibility.
