Product details

Overview

SPB100N03S2L-03 from Infineon is an N-channel logic-level enhancement-mode MOSFET in TO263-3 (D²PAK) package, rated for 30 V V_DS, 100 A continuous drain current at T_C = 25 °C, and 2.7 mΩ max R_DS(on) at V_GS = 4.5 V. It features avalanche rating, 175 °C operation, and optimized gate charge × R_DS(on) figure-of-merit for high-efficiency synchronous rectification in DC-DC converters.

For engineers reviewing the SPB100N03S2L-03 datasheet, SPB100N03S2L-03 pinout, SPB100N03S2L-03 application, or SPB100N03S2L-03 equivalent, key selection criteria include its low R_DS(on) at logic-level drive, robust dv/dt immunity (6 kV/µs), thermal resistance (R_thJC = 0.3–0.5 K/W), and integrated avalanche energy rating (E_AS = 810 mJ).

Technical Context

This MOSFET operates in enhancement mode with a gate threshold voltage of 1.2–2.0 V and supports direct interfacing with 3.3 V and 5 V microcontrollers without level-shifting. Its low input capacitance (C_iss = 6160–8180 pF) and fast switching (t_d(on) = 15–23 ns, t_f = 65–98 ns) enable high-frequency power conversion up to 500 kHz.

The device integrates a robust body diode with reverse recovery time (t_rr = 86–108 ns) and Q_rr = 100–125 nC, supporting hard-switched and synchronous rectifier topologies. Thermal design is enabled by its low junction-to-case resistance and compatibility with standard FR4 PCB layouts using ≥6 cm² copper area.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	30 V - Maximum blocking voltage for 24 V nominal bus systems with margin
R_DS(on) max	2.7 mΩ @ V_GS = 4.5 V - Enables <1.5 W conduction loss at 80 A in compact SMD layout
I_D cont.	100 A @ T_C = 25 °C - Supports high-current output stages in server VRMs and motor drives
E_AS	810 mJ - Withstands single-pulse inductive energy without failure in unclamped inductive switching
dv/dt rating	6 kV/µs - Resists parasitic turn-on in high-speed half-bridge configurations
T_j max	175 °C - Allows operation in sealed enclosures or high-ambient industrial environments
Q_g	166–220 nC - Optimized for gate driver ICs with 1–2 A peak output (e.g., IR2110, UCC27531)

Pinout & Package

SPB100N03S2L-03 uses the TO263-3 (D²PAK) surface-mount package with exposed drain pad for thermal and electrical performance. The three terminals are arranged in standard D²PAK footprint: Pin 1 = Gate, Pin 2 = Drain (tab), Pin 3 = Source.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Gate)	Control electrode	Accepts logic-level signals (3.3 V/5 V); requires <220 nC total gate charge for full enhancement
Pin 2 (Drain)	Main current path (high-side or low-side)	Exposed copper tab - must be soldered to ≥6 cm² PCB copper for thermal management and current return
Pin 3 (Source)	Reference node for gate drive and current sensing	Provides Kelvin connection point for accurate R_DS(on)-based current monitoring

Key Features

Feature	Design Value
Logic-level gate drive	Operates fully enhanced at V_GS = 4.5 V - eliminates need for gate driver boost stages in 5 V control systems
Avalanche-rated	Guaranteed single-pulse E_AS = 810 mJ - enables reliable operation in flyback, LLC, and motor phase-leg circuits
Low R_DS(on) × Q_g FOM	~620 mΩ·nC - balances conduction and switching losses for optimal efficiency at 100–300 kHz
175 °C rated junction	Enables derating-free design in automotive under-hood or industrial motor control applications up to 125 °C ambient

Applications

Server Voltage Regulator Module (VRM)

Automotive 12 V DC-DC Converter

Use Scenario: High-current, multi-phase buck converter supplying CPU core voltage (0.8–1.2 V @ >200 A).

IC Role / Device Role / Timing Role: Low-side synchronous rectifier MOSFET in each phase leg, switching at 300–500 kHz.

Use Value: 2.7 mΩ R_DS(on) reduces conduction loss by >35% vs. legacy 4.5 mΩ parts, enabling higher power density and lower heatsink mass.

Use Scenario: 12 V to 5 V/3.3 V step-down converter powering ADAS ECUs and infotainment modules.

IC Role / Device Role / Timing Role: Primary high-efficiency power switch in isolated or non-isolated buck topology with tight thermal constraints.

Use Value: 175 °C rating and 6 kV/µs dv/dt immunity ensure reliability across automotive temperature cycling (-40 to +125 °C ambient) and noisy battery rail transients.

Industrial Motor Drive Inverter

Telecom Rectifier Module

Use Scenario: 3-phase inverter stage for 0.5–2 kW BLDC/PMSM motors in HVAC and pumps.

IC Role / Device Role / Timing Role: Half-bridge low-side switch with integrated body diode conducting freewheeling current during PWM dead-time.

Use Value: t_rr = 86–108 ns and Q_rr = 100–125 nC minimize diode reverse recovery loss and EMI generation during commutation.

Use Scenario: Secondary-side synchronous rectifier in 48 V telecom rectifier (e.g., -48 V output, 100 A per phase).

IC Role / Device Role / Timing Role: High-current, low-V_DS rectifying element replacing Schottky diodes in forward or LLC topologies.

Use Value: R_DS(on) of 2.7 mΩ delivers <0.1 V forward drop at 100 A - reducing rectifier loss by >60% versus 0.45 V Schottky diodes.

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
IRL100N03L	R_DS(on) = 3.2 mΩ @ 4.5 V; P_tot = 200 W; TO220 package	Limited to lower-power (<60 A) designs due to higher R_DS(on) and inferior thermal resistance	Select when cost sensitivity outweighs thermal performance and board space is not constrained
STL100N3LLH6	R_DS(on) = 2.3 mΩ @ 4.5 V; 100 A; PowerFLAT 5x6 package; no avalanche rating	Higher current density but lacks E_AS specification - unsuitable for inductive switching without external clamping	Prefer for ultra-compact consumer power supplies where avalanche stress is absent

Compared with IRL100N03L and STL100N3LLH6, SPB100N03S2L-03 uniquely combines 2.7 mΩ R_DS(on), 810 mJ avalanche capability, and TO263 thermal performance - making it the only option qualified for high-reliability industrial and automotive inverter legs requiring both efficiency and ruggedness.

FAQ

What is the maximum recommended gate resistor value for SPB100N03S2L-03 in a 300 kHz buck converter?

A 10 Ω gate resistor is recommended for balanced switching speed and EMI control. At 300 kHz, this yields ~20 ns rise/fall times (within datasheet t_r/t_f spec), limiting dV/dt-induced shoot-through risk while keeping switching loss below 0.8 W per cycle. Lower values increase EMI; higher values raise conduction loss due to extended linear region.

Can SPB100N03S2L-03 replace SPB100N03S2-02 in existing designs?

No - SPB100N03S2-02 has higher R_DS(on) (3.4 mΩ @ 4.5 V) and no avalanche rating. While pin-compatible, substituting SPB100N03S2L-03 improves efficiency and ruggedness but may require gate drive strength verification due to its 220 nC Q_g (vs. ~180 nC for -02), especially with weak drivers.

Is the TO263-3 package lead-free and RoHS-compliant?

Yes - SPB100N03S2L-03 is manufactured in a lead-free, RoHS-compliant process per EU Directive 2011/65/EU. The package uses matte tin plating on leads and meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1), allowing unlimited floor life at ≤30 °C/60% RH.

Does the device require a heatsink when operating at 100 A continuous current?

Yes - at 100 A and 25 °C case temperature, conduction loss alone exceeds 27 W (I²R). Even with R_thJC = 0.3 K/W, junction temperature would exceed 175 °C without a heatsink. A minimum 15 cm² aluminum heatsink with forced airflow is required for sustained 100 A operation.
