Product details
Overview
SPB80N04S2-H4 from Infineon Technologies is an N-channel enhancement-mode MOSFET with 40 V VDS, 4 mΩ RDS(on) at VGS = 10 V and 80 A continuous drain current at TC = 25 °C, rated for 175 °C operation and avalanche energy of 660 mJ (single pulse), used in high-current DC-DC power stages and motor drive half-bridges.
For engineers reviewing the SPB80N04S2-H4 datasheet, SPB80N04S2-H4 pinout, SPB80N04S2-H4 application, or SPB80N04S2-H4 equivalent, key selection criteria include its 0.35 K/W typical junction-to-case thermal resistance, 111–148 nC total gate charge, 4430–5890 pF input capacitance, and TO-263-3 package suitability for high-power surface-mount PCB layouts.
Technical Context
This OptiMOS™ power transistor employs trench-gate silicon technology optimized for low conduction loss and fast switching in synchronous rectification and high-frequency buck converters. Its 5.2 V gate plateau voltage and 53–105 S transconductance support stable gate drive under high di/dt conditions.
The device integrates a robust body diode with 195–240 ns reverse recovery time and 370–460 nC Qrr, enabling reliable operation in hard-switched topologies without external snubbers. Its dv/dt rating of 6 kV/µs ensures immunity to parasitic turn-on in noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 40 V - Maximum blocking voltage in high-side switch configurations with 20 V margin above 24 V rail systems. |
| RDS(on) | 3.4–4 mΩ @ VGS = 10 V - Enables ≤3.2 W conduction loss at 80 A, critical for thermally constrained 300 W power stages. |
| ID (cont.) | 80 A @ TC = 25 °C - Supports high-current motor phase legs and battery protection circuits without forced air cooling. |
| EAS | 660 mJ - Withstands single-pulse inductive energy from 80 A load interruption at 25 V, eliminating need for external clamping. |
| Qg | 111–148 nC - Determines gate driver power requirement; compatible with standard 2 A peak drivers at ≤500 kHz switching. |
| RthJC | 0.35–0.5 K/W - Enables direct heatsink mounting on copper pads; 0.35 K/W typ allows ≤105 °C junction rise at 300 W dissipation. |
| VGS(th) | 2.1–4 V - Ensures clean turn-on with 5 V logic-level gate drive while avoiding spurious activation near ground noise. |
Pinout & Package
SPB80N04S2-H4 uses the P-TO263-3-2 surface-mount package (D²PAK), with drain connected to the exposed metal tab for low-inductance thermal and electrical path. Pin 1 = Gate, Pin 2 = Drain (tab), Pin 3 = Source.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (G) | Gate terminal | High-impedance control input requiring <100 nA leakage; routed with short, low-inductance trace to minimize ringing. |
| Pin 2 (D) | Drain terminal (exposed tab) | Primary high-current output node; electrically and thermally coupled to PCB copper pour via soldered tab. |
| Pin 3 (S) | Source terminal | Reference node for gate drive; tied to power ground plane with minimal loop area to reduce EMI. |
Key Features
| Feature | Design Value |
|---|---|
| Avalanche-rated | 660 mJ single-pulse energy handling eliminates need for external overvoltage clamps in inductive load switching. |
| 175 °C operating temperature | Enables deployment in sealed enclosures or high-ambient environments (e.g., automotive engine bays) without derating. |
| dv/dt rated (6 kV/µs) | Prevents false turn-on during fast voltage transients in motor drives and SMPS, reducing gate driver complexity. |
| Low Qgd/Qg ratio (~42%) | Improves Miller immunity and enables faster, more predictable switching transitions under varying load conditions. |
| Optimized body diode (Qrr = 370–460 nC) | Reduces reverse recovery losses and associated voltage spikes in synchronous rectifier applications. |

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 |
|---|---|---|---|
| STL220N4F7AG | RDS(on) = 3.7 mΩ, Qg = 135 nC, TO-263 package, 175 °C rating | Slightly higher gate charge increases driver loss; identical thermal footprint and avalanche capability | Preferred when gate drive voltage is limited to 5 V due to lower VGS(th) (1.5–2.5 V). |
| IXTP80N04T4 | RDS(on) = 4.2 mΩ, Qg = 92 nC, TO-220 package, 175 °C rating | Lower gate charge but TO-220 requires through-hole mounting and has higher RthJA (62 K/W vs. 40 K/W on PCB) | Selected where manual assembly or legacy board layout prohibits D²PAK rework. |
Compared with STL220N4F7AG and IXTP80N04T4, SPB80N04S2-H4 delivers the lowest RDS(on) in D²PAK form factor and best balance of gate charge and thermal performance for automated SMT production of high-power density modules.

FAQ
What is the maximum safe operating temperature for SPB80N04S2-H4?
The device is rated for continuous operation from –55 °C to +175 °C junction temperature. Its 175 °C limit allows full 80 A current capability at case temperatures up to 125 °C when mounted on a 6 cm² copper area, verified per DIN IEC 68-1 climatic category 55/175/56.
Does SPB80N04S2-H4 require a gate resistor for stability?
Yes - a 1.3 Ω gate resistor is specified in the datasheet for dynamic characterization (e.g., td(on)/td(off) measurements). For production use, values between 2.2 Ω and 10 Ω are typical to dampen gate oscillation while maintaining ≤500 kHz switching efficiency, depending on driver strength and PCB layout inductance.
Can SPB80N04S2-H4 be used in parallel configurations?
Yes - its positive temperature coefficient for RDS(on) (increasing from ~3.4 mΩ at 25 °C to ~7.5 mΩ at 150 °C) ensures inherent current sharing. Parallel operation requires matched gate drive paths, symmetrical PCB copper pours, and individual source resistors (≤10 mΩ) for current sensing and balancing.
Is the body diode suitable for synchronous rectification?
Yes - the integrated body diode has a forward voltage of 0.9–1.3 V at 80 A and reverse recovery charge of 370–460 nC, making it viable for synchronous rectification in 100–500 kHz buck converters. However, external Schottky diodes remain preferred for <100 kHz or ultra-low VF requirements.
