Product details

Overview

SPB80N04S2L-03 from Infineon Technologies is an N-channel enhancement-mode logic-level power MOSFET in TO263-3 (D²PAK) package, rated for 40 V V_DS, 80 A continuous drain current at T_C = 25 °C, and 3.1 mΩ typical R_DS(on) at V_GS = 10 V. It supports 175 °C operation, is avalanche-rated (E_AS = 810 mJ), and features dv/dt ruggedness up to 6 kV/µs - deployed in high-current DC-DC synchronous rectification and motor drive half-bridge legs.

For engineers reviewing the SPB80N04S2L-03 datasheet, SPB80N04S2L-03 pinout, SPB80N04S2L-03 application, or SPB80N04S2L-03 equivalent, key selection criteria include R_DS(on) at 4.5 V gate drive, thermal resistance (R_thJC = 0.3–0.5 K/W), reverse diode forward voltage (V_SD = 0.9–1.3 V), safe operating area (SOA) at 1 ms pulse width, and gate charge (Q_g = 160–213 nC).

Technical Context

This OptiMOS™ device uses trench-gate superjunction technology optimized for low conduction loss and fast switching in high-efficiency power stages. Its logic-level gate threshold (V_GS(th) = 1.2–2.0 V) enables direct drive from microcontrollers and PWM controllers without level-shifting.

The integrated body diode exhibits low reverse recovery charge (Q_rr = 145–180 nC) and short trr (62–78 ns), reducing commutation losses in hard-switched topologies. Thermal design is supported by validated transient impedance curves and PCB-cooling-area-dependent R_thJA values (40 K/W with 6 cm² copper).

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	40 V - Maximum blocking voltage in high-side or low-side switch configurations
R_DS(on) @ V_GS = 10 V	3.1 mΩ max - Enables ≤2.5 W conduction loss at 80 A, critical for <1% efficiency drop in 12 V input converters
I_D continuous	80 A @ T_C = 25 °C - Sustains full load in automotive HVAC blowers and industrial servo inverters
E_AS	810 mJ - Withstands single-pulse inductive energy without failure during motor stall or short-circuit events
Q_g	160–213 nC - Determines gate driver power requirement and switching speed trade-off in 100–500 kHz designs
V_GS(th)	1.2–2.0 V - Ensures turn-on with standard 3.3 V or 5 V logic outputs, eliminating external gate biasing
V_SD	0.9–1.3 V @ I_F = 80 A - Minimizes freewheeling loss in synchronous buck and H-bridge applications

Pinout & Package

SPB80N04S2L-03 is housed in a surface-mount TO263-3 (D²PAK) package with exposed drain pad for thermal performance. The three terminals are arranged as Drain (pins 1 & 2, common), Source (pin 3), and Gate (pin 1, isolated).

Pin/Terminal	Circuit Role	Design Meaning
Drain (Pins 1 & 2)	Main current path collector	Electrically and thermally connected to large copper area on PCB; primary heat transfer path to heatsink
Source (Pin 3)	Reference node for gate drive and current sensing	Low-inductance return path; used for Kelvin source connection in precision current monitoring
Gate (Pin 1)	Control electrode	Isolated input requiring <213 nC charge; sensitive to ESD; routed away from noisy power traces

Key Features

Feature	Design Value
Logic-level gate drive	Operates fully enhanced at V_GS ≥ 4.5 V, compatible with 3.3 V MCU GPIOs and low-voltage PWM ICs
Avalanche ruggedness	Rated for repetitive unclamped inductive switching (EAR = 30 mJ), enabling robust motor control without snubbers
dv/dt immunity	6 kV/µs - Prevents false turn-on during fast voltage transients in high-noise industrial environments
High-temperature operation	175 °C maximum junction temperature - Supports under-hood automotive and enclosed industrial enclosure use
Low Q_gd/Q_g ratio	54–81 nC / 160–213 nC - Improves Miller immunity and reduces switching loss during hard commutation

Applications

Motor Drive Half-Bridge Leg

Server PSU Primary-Side Switch

Use Scenario: 24 V brushed DC motor control in warehouse automation conveyors with regenerative braking.

IC Role / Device Role / Timing Role: High-current switching element in H-bridge leg, subjected to bidirectional current and inductive flyback.

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
IRF8720PbF	R_DS(on) = 4.0 mΩ @ 10 V; Q_g = 22 nC lower; TO220 package only	Limited to leaded mounting; lacks SMD thermal performance and avalanche rating	Prefer for cost-sensitive, non-SMD, low-frequency (<100 kHz) applications where PCB space is not constrained
STL110N4LF6	R_DS(on) = 2.8 mΩ @ 10 V; 60 V rating; DFN8 5×6 mm package	Higher voltage margin but smaller footprint; no official avalanche rating or dv/dt spec	Choose when board area is critical and 60 V headroom is required, but avoid in high-dv/dt or unclamped inductive loads

Compared with IRF8720PbF and STL110N4LF6, SPB80N04S2L-03 uniquely combines SMD thermal capability (R_thJC ≤ 0.5 K/W), 175 °C operation, and certified avalanche/dv/dt ruggedness - making it the only option qualified for automotive-grade motor control and industrial UPS systems demanding reliability under transient stress.

FAQ

What is the maximum gate-source voltage rating for SPB80N04S2L-03?

The absolute maximum V_GS is ±20 V, per the datasheet's "Maximum Ratings" table. Operation beyond ±16 V risks permanent gate oxide damage. For reliable logic-level drive, keep V_GS between 4.5 V and 15 V, with 10 V recommended for minimum R_DS(on) and optimal switching performance.

Can SPB80N04S2L-03 be used in parallel configurations?

Yes - its positive temperature coefficient of R_DS(on) (confirmed in Fig. 9) ensures inherent current sharing. Parallel operation requires matched gate drive layout, identical PCB copper area per device, and Kelvin source connections to minimize imbalance. Derate total current by 15% for thermal margin in multi-device arrays.

Does SPB80N04S2L-03 have a qualified AEC-Q101 rating?

No - while SPB80N04S2L-03 meets automotive ambient temperature requirements (T_j = −55 °C to +175 °C) and is widely used in automotive subsystems, it is not formally AEC-Q101 qualified. For AEC-Q101-compliant alternatives, consider Infineon's BSC010N04LS or BSZ050N04NS.

What is the recommended PCB footprint for thermal performance?

Per datasheet note on page 2, use a 40 mm × 40 mm × 1.5 mm FR4 PCB with ≥6 cm² of 70 µm-thick copper connected to the drain pad (pins 1 & 2). Avoid thermal relief spokes; use solid copper pour and multiple vias (≥8 × 0.5 mm) to internal ground planes to achieve R_thJA ≈ 40 K/W.
