Product details

Overview

SPP42N03S2L13 from Infineon Technologies is an N-channel enhancement-mode power MOSFET in TO-220-3 package, rated for 30 V V_DS, 42 A continuous drain current (T_C = 25 °C), and 7.5 mΩ typical R_DS(on) at V_GS = 10 V. It is designed for high-efficiency DC-DC converters and motor control stages in industrial power supplies.

For engineers reviewing the SPP42N03S2L13 datasheet, SPP42N03S2L13 pinout, SPP42N03S2L13 application, or SPP42N03S2L13 equivalent, key selection criteria include low conduction loss at 10 V gate drive, thermal performance in TO-220 mounting, and safe operating area robustness under repetitive avalanche conditions.

Technical Context

This MOSFET employs Infineon's OptiMOS™ 2 technology, delivering optimized trade-offs between switching speed and on-resistance. Its gate threshold voltage (V_GS(th)) is specified at 1.0–2.5 V, enabling compatibility with 3.3 V and 5 V logic-level drivers.

The device features a fully avalanche-rated structure (E_AS = 190 mJ at T_J = 25 °C), integrated body diode with soft recovery characteristics (t_rr = 55 ns), and guaranteed 100% UIS testing per production lot.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	30 V - Maximum blocking voltage in common-source configuration; supports 24 V rail systems with margin.
I_D (continuous)	42 A @ T_C = 25 °C - Sustained current capability with heatsink; derates to 28 A at T_C = 100 °C.
R_DS(on)	7.5 mΩ (typ) @ V_GS = 10 V - Enables <1 W conduction loss at 30 A, critical for high-current synchronous rectification.
Q_g	32 nC - Total gate charge determines driver strength requirement; compatible with standard half-bridge gate drivers.
E_AS	190 mJ - Energy-handling capacity during unclamped inductive switching; ensures reliability in relay/snubberless motor drive circuits.
t_rr	55 ns - Body diode reverse recovery time; reduces switching loss and EMI in freewheeling paths.

Pinout & Package

Package: TO-220-3 (full-pack, straight lead, isolated tab). Tab is connected to Drain (D); leads are Gate (G), Drain (D), Source (S) - left-to-right when viewing front side with tab up.

Pin/Terminal	Circuit Role	Design Meaning
G	Gate	Controls channel conduction; requires ≥10 V for full enhancement; Miller plateau at ~4.5 V.
D	Drain	High-side switch node; electrically tied to metal tab; must be insulated from heatsink unless referenced to same potential.
S	Source	Return path for load current; reference for gate drive; used for current sensing in low-side configurations.

Key Features

Feature	Design Value
OptiMOS™ 2 process	Enables 7.5 mΩ R_DS(on) at 30 V while maintaining fast switching (t_d(on) = 12 ns, t_f = 15 ns).
100% UIS tested	Guarantees ruggedness against inductive turn-off stress without external snubbers in motor gate drives.
Soft-recovery body diode	Reduces voltage overshoot and ringing during commutation, lowering EMI filter burden in DC-DC designs.
Logic-level compatible	V_GS(th) range (1.0–2.5 V) allows direct drive from microcontroller GPIOs with minimal external level-shifting.

Applications

Industrial Motor Control

Server VRM / POL Converter

Use Scenario: Half-bridge driver stage in 24 V BLDC motor controllers for HVAC blowers and conveyor systems.

IC Role / Device Role / Timing Role: Low-side switching element handling peak currents up to 40 A with PWM frequencies ≤50 kHz.

Use Value: Low R_DS(on) minimizes I²R losses during continuous conduction mode, improving thermal margin at ambient temperatures up to 70 °C.

Use Scenario: Synchronous rectifier in 30 A, 12 V → 1.2 V point-of-load buck converter for CPU core power delivery.

IC Role / Device Role / Timing Role: High-current, low-voltage output switch with fast turn-on/turn-off to reduce dead-time losses.

Use Value: 32 nC Q_g enables efficient drive with IR35201 controller, achieving >92% efficiency at 20 A load.

Automotive Body Control Module

UPS Inverter Stage

Use Value: Soft-recovery body diode limits dv/dt-induced shoot-through risk and reduces gate driver stress during zero-crossing transitions.

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
STP40NF03L	R_DS(on) = 9.5 mΩ (typ) at V_GS = 10 V; higher Q_g = 45 nC; no UIS rating specified.	Lacks guaranteed avalanche ruggedness; less suitable for inductive switching without snubbers.	Prefer SPP42N03S2L13 where unclamped inductive energy is present.
IRF3205	R_DS(on) = 8.0 mΩ (typ); V_DS = 55 V; Q_g = 71 nC; slower switching (t_f = 50 ns).	Higher voltage rating adds cost and capacitance; excessive for 24 V systems.	SPP42N03S2L13 offers better efficiency and thermal performance in 30 V-class designs.

Compared with STP40NF03L and IRF3205, SPP42N03S2L13 delivers lower conduction loss, faster switching, and verified avalanche capability-making it optimal for compact, high-reliability 24–30 V power stages where thermal headroom and transient robustness are critical.

FAQ

Is SPP42N03S2L13 suitable for surface-mount assembly?

No. SPP42N03S2L13 uses a through-hole TO-220-3 package with bent leads and an isolated metal tab. It requires hole mounting and mechanical screw-down to a heatsink. Surface-mount alternatives like IPP42N03S2L13 (TO-263) exist but are distinct orderable parts.

What is the maximum allowable junction temperature for continuous operation?

The absolute maximum junction temperature is 175 °C. For reliable continuous operation, Infineon specifies T_J ≤ 150 °C under steady-state conditions. Derating curves in the datasheet define usable I_D versus T_C, with 42 A valid only at T_C = 25 °C.

Does SPP42N03S2L13 require a gate resistor for stability?

Yes. A series gate resistor (typically 5–22 Ω) is recommended to dampen gate oscillation and control dV/dt during switching. The value balances switching speed against EMI and shoot-through risk, especially when paralleled or driven by high-current gate drivers.

Can this MOSFET replace older IRF series devices in legacy designs?

Yes-with verification. SPP42N03S2L13 matches pinout and voltage/current ratings of IRF3205 and IRF1404 but improves R_DS(on), Q_g, and avalanche rating. Layout and gate drive must be reviewed for parasitic inductance and voltage overshoot due to faster switching.
