Product details

Overview

SPD30N03S2L-20 from Infineon Technologies is an N-channel enhancement-mode logic-level power MOSFET in TO252 (DPAK) package, rated for 30 V V_DS, 30 A continuous drain current at T_C = 25 °C, and 20 mΩ typical R_DS(on) at V_GS = 10 V. It features avalanche rating, 175 °C maximum junction temperature, and optimized gate charge × R_DS(on) figure-of-merit for high-efficiency DC-DC converters and motor drive half-bridges.

For engineers reviewing the SPD30N03S2L-20 datasheet, SPD30N03S2L-20 pinout, SPD30N03S2L-20 application, or SPD30N03S2L-20 equivalent, key selection criteria include its 4.5 V logic-level gate drive compatibility, 70 mJ single-pulse avalanche energy, thermal resistance of 1.7 K/W (junction-to-case), and robust dv/dt immunity up to 6 kV/µs - critical for inductive switching reliability in automotive body control modules and industrial power supplies.

Technical Context

This OptiMOS™ device uses trench-gate silicon technology with optimized cell pitch and deep-trench source contact to achieve low R_DS(on) while maintaining fast switching and rugged unclamped inductive switching (UIS) capability. Its gate threshold voltage (1.2–2.0 V) ensures reliable turn-on with standard 3.3 V or 5 V microcontroller outputs.

The MOSFET integrates a co-packaged, fast-recovery body diode (t_rr = 15–18 ns, Q_rr = 2–3 nC) with low forward voltage (V_SD = 1.1–1.4 V at 30 A), enabling efficient synchronous rectification and freewheeling in buck converters and H-bridge motor drivers without external diodes.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	30 V - Maximum blocking voltage compatible with 24 V automotive and industrial bus systems
R_DS(on) @ V_GS = 10 V	20 mΩ max - Enables ≤0.6 W conduction loss at 30 A, reducing heatsink requirements
I_D continuous	30 A @ T_C = 25 °C - Supports high-current load switching in compact PCB layouts
E_AS	70 mJ - Withstands single-pulse inductive energy without failure in relay/motor drive snubbing
Q_g	14.3–19 nC - Low gate charge enables fast switching with modest gate driver current (e.g., 1 A peak)
T_j max	175 °C - Rated for under-hood automotive environments and sealed industrial enclosures
dv/dt rating	6 kV/µs - Immune to false triggering during high-slew-rate transients in noisy ECU power stages

Pinout & Package

Package: TO252-3-11 (DPAK), surface-mount, single-drain tab configuration with exposed drain pad for thermal conduction to PCB copper.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Source)	Source terminal	Low-side reference node; connects to ground or current-sense shunt for feedback
Pin 2 (Gate)	Control input	Logic-level compatible; requires <2.0 V V_GS(th) to initiate conduction
Pin 3 (Drain)	Power output / high-side connection	Exposed metal tab - must be soldered to ≥6 cm² copper pour for thermal performance

Key Features

Feature	Design Value
Logic-level gate drive	Turns on fully with 4.5 V gate voltage - eliminates need for gate boosters in 3.3 V MCU designs
Avalanche-rated	70 mJ single-pulse energy handling - supports reliable operation in inductive load switching without external clamping
Low R_DS(on) × Q_g FOM	~400 mΩ·nC - balances conduction and switching losses for high-frequency (≥200 kHz) SMPS efficiency
175 °C operation	Rated junction temperature - enables use in thermally constrained spaces like engine control units and LED drivers
Fast body diode	t_rr = 15–18 ns, Q_rr = 2–3 nC - minimizes reverse recovery loss and EMI in synchronous rectifier topologies

Applications

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
IRLZ44NPBF	R_DS(on) = 25 mΩ @ 10 V; lower avalanche rating (E_AS = 45 mJ); higher Q_g (27 nC)	Less suitable for high-reliability automotive UIS stress; slower switching increases loss above 100 kHz	Lower-cost option where thermal margin and avalanche robustness are non-critical
STP30NF03L	R_DS(on) = 22 mΩ @ 10 V; no specified dv/dt rating; T_j max = 150 °C	Not qualified for 175 °C under-hood use; lacks documented dv/dt immunity for noisy ECU environments	Acceptable for industrial controls below 125 °C ambient, but not for automotive AEC-Q101 deployment

Compared with IRLZ44NPBF and STP30NF03L, SPD30N03S2L-20 delivers superior thermal capability (175 °C), higher avalanche energy (70 mJ), and guaranteed dv/dt immunity - making it the preferred choice for mission-critical automotive and high-reliability industrial power switching where long-term field robustness is mandatory.

FAQ

Is SPD30N03S2L-20 pin-compatible with standard TO252-3 packages?

Yes - it uses the industry-standard TO252-3-11 (DPAK) footprint with 2.3 mm lead pitch and 6.5 mm × 6.2 mm body dimensions. Pin 1 is Source, Pin 2 is Gate, and Pin 3 is Drain (exposed tab). Layout matches JEDEC MS-012AC, enabling drop-in replacement in existing DPAK designs.

What is the maximum recommended gate resistor for 100 kHz PWM switching?

A 10 Ω gate resistor is recommended for 100 kHz operation with 1 A peak gate driver current. This value balances switching speed (t_r/t_f ≈ 11–26 ns) against ringing and EMI, based on measured Q_g = 14.3–19 nC and C_iss = 530–700 pF at 25 V.

Does SPD30N03S2L-20 require a gate pull-down resistor in microcontroller-driven applications?

Yes - a 10 kΩ pull-down resistor between Gate and Source is required to ensure defined off-state during MCU reset or I/O floating conditions. The device's 1.2–2.0 V V_GS(th) makes it susceptible to noise-induced turn-on without active gate bias control.

Can SPD30N03S2L-20 be used in parallel configurations for higher current?

Yes - its positive R_DS(on) temperature coefficient (R_DS(on) increases with T_j) enables inherent current sharing. Parallel operation requires matched layout, identical gate drive paths, and thermal coupling via shared copper area to maintain <5 °C inter-device ΔT for stable load distribution.
