Product details

Overview

SPD100N03S2L04T from Infineon Technologies is an N-channel logic-level enhancement-mode power MOSFET in PG-TO252-5-1 (DPAK) package, rated for 30 V V_DS, 4.2 mΩ R_DS(on) at V_GS = 10 V and 50 A, and 100 A continuous drain current at T_C = 100 °C. It features avalanche rating, 175 °C maximum junction temperature, and optimized gate charge × R_DS(on) figure-of-merit for high-efficiency DC-DC and motor drive switching.

For engineers reviewing the SPD100N03S2L04T datasheet, SPD100N03S2L04T pinout, SPD100N03S2L04T application, or SPD100N03S2L04T equivalent, key selection criteria include its 4.2 mΩ on-resistance at 10 V gate drive, 100 A thermal current capability, logic-level gate threshold (1.2–2.0 V), integrated body diode with 46 ns reverse recovery time, and TO252-5 footprint compatibility with PCB cooling area optimization.

Technical Context

This OptiMOS™ device uses trench-gate superjunction technology to achieve low R_DS(on) while maintaining robust dv/dt immunity (6 kV/µs) and unclamped inductive switching (UIS) capability (325 mJ single-pulse E_AS). Its gate plateau voltage of 3.6 V enables stable turn-on under noisy conditions.

The MOSFET supports synchronous rectification and high-frequency PWM operation up to 1 MHz, enabled by low C_iss (2500–3320 pF), C_oss (980–1300 pF), and Q_g (67.5–89.7 nC), with fast switching times (t_r = 17–26 ns, t_f = 24–36 ns) under 2.7 Ω gate resistance.

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	4.2 mΩ max - Enables ≤1.05 W conduction loss at 50 A, critical for thermally constrained PCB layouts
I_D continuous @ T_C=100 °C	100 A - Sustains high-current loads without derating when mounted on ≥6 cm² copper area
Q_g	67.5–89.7 nC - Determines gate driver power requirement and switching loss trade-off at 100 kHz–1 MHz
E_AS	325 mJ - Supports reliable operation in inductive load switching without external snubbers
T_j max	175 °C - Allows operation in under-hood or sealed industrial enclosures without active cooling
R_thJC	0.7–1.0 K/W - Enables direct thermal path to heatsink via drain-connected copper pad

Pinout & Package

Package: PG-TO252-5-1 (DPAK variant with 5 terminals, 1.5 mm PCB thickness, FR4 substrate). Drain connected to exposed pad (pins 3 & 6); source connected to pins 4 & 5; gate at pin 1; pin 2 is no-connect but must be tied to gate on PCB per layout guidance.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Gate	Main control input; requires low-impedance drive due to 89.7 nC total gate charge
Pin 2	No-connect (NC)	Must be electrically tied to pin 1 on PCB to reduce gate loop inductance
Pins 3 & 6	Drain	High-current output node; soldered to large copper area for thermal dissipation
Pins 4 & 5	Source	Power return path; dual connection reduces source inductance in high-di/dt applications

Key Features

Feature	Design Value
Logic-level gate drive	V_GS(th) = 1.2–2.0 V enables direct interface with 3.3 V/5 V microcontrollers without level-shifting
Avalanche-rated	325 mJ single-pulse E_AS ensures ruggedness in motor commutation and relay driving
Low thermal resistance	R_thJC = 0.7 K/W allows >150 W power dissipation with minimal ΔT between die and heatsink
Optimized FOM	Q_g × R_DS(on) ≈ 375 nC·mΩ - balances switching loss and conduction loss for 100–500 kHz operation
dv/dt immune	Rated for 6 kV/µs - suppresses false turn-on in high-noise half-bridge configurations

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRF100N03L3PBF	R_DS(on) = 3.2 mΩ @ 10 V, but higher Q_g (105 nC) and no avalanche rating	Better conduction loss only in low-frequency, high-current apps where switching loss is secondary	Select if lowest R_DS(on) dominates and UIS ruggedness is not required
STL100N3LLH6	Same 30 V/4.2 mΩ rating but in PowerFLAT 5x6 package; lower R_thJA (30 K/W) but no exposed drain pad	Suitable for space-constrained surface-mount designs where thermal vias replace heatsinking	Select for ultra-thin consumer electronics where DPAK height is prohibitive

Compared with IRF100N03L3PBF and STL100N3LLH6, SPD100N03S2L04T uniquely combines avalanche ruggedness, low gate charge × R_DS(on) FOM, and TO252-5 thermal performance-making it optimal for automotive and industrial switching where reliability under transient stress is non-negotiable.

FAQ

What is the maximum safe operating temperature for SPD100N03S2L04T?

The device supports continuous operation up to T_j = 175 °C, verified by design and validated through UIS testing. Derating begins above T_C = 100 °C per the ID vs. TC curve on page 4 of the datasheet; thermal design must maintain junction temperature below 175 °C under worst-case ambient and power dissipation conditions.

Can SPD100N03S2L04T be used in synchronous rectification topologies?

Yes-the integrated body diode has t_rr = 46–58 ns and Q_rr = 56–69 nC, enabling efficient synchronous rectification in buck and forward converters up to 500 kHz. Gate drive timing must account for V_plateau = 3.6 V to avoid cross-conduction during dead-time transitions.

Is pin 2 internally connected or truly unused?

Pin 2 is a no-connect terminal with no internal bond wire. However, the datasheet explicitly requires it to be externally tied to pin 1 (gate) on the PCB to minimize gate loop inductance and improve switching stability-this is a layout mandate, not optional.

Does SPD100N03S2L04T require a gate resistor for ESD protection?

No dedicated ESD resistor is needed-the device meets HBM Class 2 (≥2 kV) per JESD22-A114. However, a 2.7 Ω gate resistor is specified in dynamic test conditions to control dV/dt and ringing; values between 1 Ω and 10 Ω are typical for balancing switching speed and gate drive stability.
