Product details
Overview
SPD30N03S2L10T from Infineon Technologies is an N-channel logic-level enhancement-mode MOSFET optimized for high-efficiency DC-DC conversion and motor control. It delivers 30 A continuous drain current at TC = 25 °C, 10 mΩ RDS(on) at VGS = 10 V, and operates up to 175 °C junction temperature-enabling compact, thermally robust power stages in automotive body electronics and industrial SMPS.
For engineers reviewing the SPD30N03S2L10T datasheet, SPD30N03S2L10T pinout, SPD30N03S2L10T application, or SPD30N03S2L10T equivalent, key selection criteria include its 10 mΩ on-resistance at 10 V gate drive, 150 mJ single-pulse avalanche energy, 6 kV/µs dv/dt rating, and TO-252 (DPAK) package thermal resistance of 1.5 K/W junction-to-case.
Technical Context
This OptiMOS™ power transistor uses trench-gate silicon technology to achieve low gate charge × RDS(on) figure-of-merit (FOM), enabling fast switching with reduced conduction and switching losses. Its logic-level gate threshold (1.2–2.0 V) ensures full enhancement with standard 3.3 V or 5 V microcontroller outputs.
The device integrates a robust intrinsic body diode rated for 30 A continuous forward current and 31–39 ns reverse recovery time, supporting synchronous rectification and freewheeling in buck converters and H-bridge motor drivers without external diode supplementation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 30 V - maximum blocking voltage compatible with 24 V automotive and industrial bus systems |
| RDS(on) @ VGS = 10 V | 7.8–10 mΩ - enables <1 W conduction loss at 30 A, reducing heatsink requirements |
| ID (continuous) | 30 A @ TC = 25 °C - supports high-current load switching in power distribution modules |
| EAS | 150 mJ - withstands inductive energy spikes in relay/motor drive circuits without failure |
| dv/dt rating | 6 kV/µs - immune to false turn-on during fast transient noise in noisy ECU environments |
| Tj max | 175 °C - allows operation in under-hood or enclosed industrial enclosures without derating |
| Qg | 31.4–41.8 nC - balances switching speed and gate driver power consumption in 100–500 kHz SMPS |
Pinout & Package
SPD30N03S2L10T is housed in a surface-mount TO-252-3 (DPAK) package with exposed drain pad for enhanced thermal performance. The package features 1.5 K/W typical junction-to-case thermal resistance and is optimized for PCB copper area cooling (6 cm² recommended).

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel logic-level MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRL3803PbF | RDS(on) = 12 mΩ @ 10 V; lower EAS (100 mJ); no dv/dt rating specified | Lacks avalanche and dv/dt specs - unsuitable for inductive switching in automotive BCM | Prefer SPD30N03S2L10T where robustness against load dump or motor back-EMF is required |
| STL30N03LH5 | RDS(on) = 9.5 mΩ @ 10 V; higher Qg (48 nC); Tj max = 150 °C | Lower thermal limit restricts continuous 30 A operation in confined spaces | Choose SPD30N03S2L10T when ambient exceeds 105 °C or long-term reliability at 175 °C is mandatory |
Compared with IRL3803PbF and STL30N03LH5, SPD30N03S2L10T uniquely combines 150 mJ avalanche capability, 6 kV/µs dv/dt immunity, and 175 °C operation-making it the only option qualified for demanding automotive and industrial power switching where fault resilience and thermal headroom are non-negotiable.

FAQ
What is the maximum gate-source voltage for SPD30N03S2L10T?
The absolute maximum gate-source voltage is ±20 V. Operation beyond this risks permanent gate oxide damage. For reliable logic-level drive, apply 4.5–10 V to ensure full enhancement while maintaining margin against transients. Gate drive circuits must include clamping or Zener protection if exposed to >12 V supply rails.
Can SPD30N03S2L10T be used in linear mode for adjustable current limiting?
Yes-it supports linear-mode operation with a maximum junction temperature of 175 °C and 1.5 K/W junction-to-case thermal resistance. At 30 A and 10 mΩ, power dissipation is 9 W; using ≥6 cm² copper area keeps case temperature below 100 °C, enabling stable current regulation without thermal shutdown.
Is the body diode suitable for synchronous rectification in a 200 kHz flyback converter?
Yes-the body diode has 31–39 ns reverse recovery time and 29–37 nC Qrr, making it viable for synchronous rectification up to 300 kHz. Its 0.9–1.2 V forward voltage at 30 A yields lower conduction loss than a 40 V Schottky diode, improving efficiency by ~1.2% at full load.
Does SPD30N03S2L10T require a gate resistor for stability in motor drive applications?
Yes-a series gate resistor of 3.3–5.4 Ω is recommended to damp ringing and control dV/dt during switching. This value balances turn-on/turn-off times (6–9 ns td(on), 27–41 ns td(off)) while preventing oscillation caused by gate-drain capacitance coupling in H-bridge configurations.
