Product details

Overview

SPP100N03S2L03 from Infineon Technologies is an N-channel enhancement-mode power MOSFET in TO-220-3 package, rated for 30 V V_DS, 100 A I_D (T_C=25°C), and 3.0 mΩ R_DS(on) max at V_GS=10 V. It serves as a high-current synchronous rectifier or low-side switch in DC-DC converters and motor drives.

For engineers reviewing the SPP100N03S2L03 datasheet, SPP100N03S2L03 pinout, SPP100N03S2L03 application, or SPP100N03S2L03 equivalent, key selection criteria include on-resistance at 10 V gate drive, peak pulsed current capability, thermal resistance (R_thJC = 0.9 K/W), and avalanche ruggedness rating.

Technical Context

This MOSFET employs Infineon's OptiMOS™ 2nd generation trench technology, delivering low conduction losses and fast switching with t_fall = 24 ns and Q_g = 68 nC. Its gate threshold voltage (V_GS(th)) ranges from 1.0 V to 2.5 V, enabling compatibility with 3.3 V and 5 V logic-level drivers.

The device features 100% UIS-tested avalanche capability (E_AS = 470 mJ at T_J=25°C) and is qualified per AEC-Q101 for automotive-grade reliability. Thermal design relies on its 0.9 K/W junction-to-case resistance and TO-220-3's exposed drain pad for direct heatsink mounting.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	30 V - Maximum drain-source blocking voltage for 12 V automotive and industrial bus applications
R_DS(on) max	3.0 mΩ @ V_GS = 10 V - Enables <1 W conduction loss at 100 A continuous DC current
I_D (T_C=25°C)	100 A - Continuous drain current rating with adequate heatsinking
Q_g	68 nC - Total gate charge determining driver strength requirement for 100 kHz–500 kHz switching
E_AS	470 mJ - Single-pulse avalanche energy supporting inductive load switching without external snubbers
R_thJC	0.9 K/W - Junction-to-case thermal resistance enabling 60 W dissipation with 54 K case-to-ambient delta

Pinout & Package

TO-220-3 package with isolated tab (drain-connected), standard through-hole mounting, and JEDEC outline TO-220AB. Pin 1 = Gate, Pin 2 = Drain (tab), Pin 3 = Source.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (left)	Gate	Control terminal requiring ≤68 nC charge for full enhancement; insulated from heatsink
Pin 2 (center/tab)	Drain	Main high-current path; electrically connected to metal tab for low-inductance heatsink interface
Pin 3 (right)	Source	Reference node for gate drive; tied to PCB ground plane with low-inductance layout

Key Features

Feature	Design Value

100% UIS avalanche tested	Guarantees 470 mJ single-pulse energy handling without derating in motor control flyback events
Logic-level compatible V_GS(th)	1.0–2.5 V threshold enables direct drive from MCU GPIOs or low-voltage gate drivers
TO-220-3 with isolated tab	Allows mechanical mounting to heatsink without insulating hardware while maintaining electrical isolation of gate

Applications

Use Scenario: Switching 12 V battery power to solenoids, lamps, and window lift motors.

IC Role / Device Role / Timing Role: Low-side power switch controlling load current with PWM duty cycle modulation.

Use Value: 3.0 mΩ R_DS(on) limits resistive heating to <1.5 W at 70 A peak, eliminating need for active cooling.

Use Scenario: H-bridge leg in 24 V brushed DC motor controller for conveyor systems.

IC Role / Device Role / Timing Role: Synchronous rectifier in freewheeling path during PWM off-time.

Use Value: Low Q_g (68 nC) and fast t_fall (24 ns) reduce switching losses below 0.8 W at 20 kHz operation.

Use Scenario: High-side switch in multiphase buck converter supplying CPU core voltage.

IC Role / Device Role / Timing Role: Power stage transistor operating in hard-switched synchronous rectification mode.

Use Value: Avalanche ruggedness (470 mJ) tolerates voltage overshoot during phase current commutation transients.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel 30 V power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP100N3LLH6	R_DS(on) = 2.8 mΩ @ 10 V, Q_g = 72 nC, TO-220FP package (lower profile)	Same 30 V/100 A rating but higher gate charge increases driver loss; FP variant has reduced height for space-constrained layouts	Select when board height is constrained and gate driver can supply extra 4 nC; verify thermal performance with lower-case R_thJC
IRF1404ZPBF	R_DS(on) = 4.0 mΩ @ 10 V, Q_g = 131 nC, no UIS rating, legacy TrenchFET® Gen 1	Lacks avalanche testing and has 33% higher conduction loss; suitable only for non-inductive, low-frequency switching	Use only in cost-sensitive, non-automotive designs where avalanche immunity and efficiency are secondary

Compared with STP100N3LLH6 and IRF1404ZPBF, SPP100N03S2L03 offers superior avalanche ruggedness and lower gate charge-critical for high-reliability automotive and high-frequency industrial converters-while maintaining identical TO-220-3 footprint and thermal interface.

FAQ

What is the maximum allowable junction temperature for continuous operation?

The SPP100N03S2L03 has a rated maximum junction temperature of 175°C. Continuous operation at this limit requires thermal design ensuring junction-to-case temperature rise remains within R_thJC × P_D, with derating applied above 25°C ambient per the datasheet's thermal curves.

Is the TO-220-3 package lead-free and RoHS compliant?

Yes, SPP100N03S2L03 is manufactured in a lead-free, RoHS-compliant process per EU Directive 2011/65/EU. The device carries the "Pb-free" marking on the package and meets JEDEC J-STD-020 moisture sensitivity level MSL-1.

Does this MOSFET require a gate resistor for safe switching?

A gate resistor (typically 5–22 Ω) is recommended to dampen ringing and control dV/dt during turn-on/turn-off. The 68 nC gate charge and low output capacitance make it susceptible to oscillation without proper gate drive impedance matching.

Can SPP100N03S2L03 be used in parallel configurations?

Yes-its positive temperature coefficient of R_DS(on) supports current sharing. Parallel operation requires matched gate drive paths, symmetrical PCB layout, and individual gate resistors to ensure simultaneous switching and prevent dynamic imbalance.
