Product details
Overview
SPD14N06S2-80 from Infineon Technologies is an N-channel enhancement-mode OptiMOS™ power MOSFET rated for 55 V VDS, 80 mΩ RDS(on) (max), and 17 A continuous drain current at TC = 25 °C. It operates up to 175 °C, features avalanche and dv/dt ruggedness, and is housed in a TO252-3 (DPAK) package - commonly used in DC-DC converters, motor control stages, and industrial power switching.
For engineers reviewing the SPD14N06S2-80 datasheet, SPD14N06S2-80 pinout, SPD14N06S2-80 application, or SPD14N06S2-80 equivalent, key selection criteria include its 53–80 mΩ on-resistance at VGS = 10 V, 43 mJ single-pulse avalanche energy, 6 kV/µs dv/dt rating, and thermal resistance of 2.14 K/W (junction-to-case), critical for high-reliability 12–24 V power systems.
Technical Context
This MOSFET employs trench-gate silicon technology optimized for low conduction and switching losses in medium-voltage, high-current applications. Its gate threshold voltage (2.1–4.0 V) enables compatibility with 3.3 V and 5 V logic-level drivers, while its 302–400 pF input capacitance and 8–10 nC total gate charge support efficient PWM operation at frequencies up to several hundred kHz.
The integrated body diode exhibits 0.9–1.3 V forward voltage at 14 A and 25–31 ns reverse recovery time, making it suitable for synchronous rectification and freewheeling in buck converters and H-bridge motor drives where diode performance impacts efficiency and EMI.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS Rating | 55 V - supports 24 V nominal bus systems with ≥30 % overvoltage margin for transients and inductive kickback |
| RDS(on) (max) | 80 mΩ at VGS = 10 V, ID = 7 A - determines conduction loss (Pcond ≈ I² × 0.08 Ω) in continuous load paths |
| ID (cont) | 17 A at TC = 25 °C - defines maximum steady-state current before thermal derating begins |
| EAS | 43 mJ single-pulse - quantifies robustness against inductive energy dump without failure under unclamped inductive switching |
| dv/dt Rating | 6 kV/µs - ensures immunity to false turn-on during fast voltage transients in high-noise motor or relay drive environments |
| Tj Max | 175 °C - enables operation in sealed enclosures or high-ambient industrial settings without forced cooling |
| Qg | 8–10 nC - sets gate driver power requirement and influences switching speed trade-off between loss and EMI |
Pinout & Package
SPD14N06S2-80 is packaged in TO252-3 (DPAK), a surface-mount power package with exposed drain pad for thermal conduction to PCB copper. The three terminals are arranged in standard DPAK orientation: Pin 1 = Gate, Pin 2 = Drain (tab), Pin 3 = Source.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (left) | Gate | Control terminal; requires ≤±20 V drive; 1.6–2 nC Qgs minimizes Miller-induced delay in hard-switching |
| Pin 2 (center tab) | Drain | Main high-side current path; electrically connected to exposed copper pad - must be soldered to ≥6 cm² PCB copper for RthJA = 50 K/W |
| Pin 3 (right) | Source | Reference node for gate drive and current sensing; ties to power ground plane; carries full load current |
Key Features
| Feature | Design Value |
|---|---|
| Avalanche-rated operation | Guarantees reliable unclamped inductive switching up to 43 mJ per pulse without parameter shift or failure |
| 175 °C junction temperature rating | Enables use in thermally constrained environments (e.g., sealed motor drives, automotive under-hood modules) |
| Low RDS(on) × Qg figure-of-merit | ~640 mΩ·nC - balances conduction and switching loss for high-efficiency 100–500 kHz SMPS designs |
| dv/dt ruggedness | 6 kV/µs tolerance prevents spurious turn-on during fast-rising edge noise in half-bridge configurations |
| Optimized body diode | 25–31 ns trr and 35–44 nC Qrr reduce switching loss and voltage overshoot in synchronous rectifier applications |
Applications
| DC-DC Buck Converter | Brushed DC Motor Driver |

IC Role / Device Role / Timing Role: Ideal diode replacement in active OR-ing configuration with fast reverse recovery. Use Value: 25–31 ns trr and low Qrr minimize cross-conduction loss and voltage spikes during supply switchover. |
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 |
|---|---|---|---|
| IPB120N04S4-02 | 40 V VDS, 2.0 mΩ RDS(on), TO263 package - lower voltage, much lower on-resistance, larger footprint | Better suited for 12 V systems requiring ultra-low loss; not safe for 24 V transient conditions | Select only if bus voltage stays ≤16 V and thermal budget allows TO263 mounting |
| IRFZ44NPBF | 55 V VDS, 28 mΩ RDS(on), TO220 - older planar process, higher Qg (71 nC), no avalanche rating | Higher switching loss and no guaranteed avalanche immunity limit reliability in inductive loads | Acceptable for cost-sensitive, low-frequency (<50 kHz), non-critical applications without repetitive stress |
Compared with IPB120N04S4-02 and IRFZ44NPBF, SPD14N06S2-80 delivers optimal balance of 55 V rating, moderate RDS(on), proven avalanche ruggedness, and DPAK thermal performance - making it preferred for 24 V industrial switching where reliability and board space are both constraints.

FAQ
Is SPD14N06S2-80 suitable for 24 V automotive applications?
Yes - its 55 V VDS rating exceeds ISO 7637-2 load-dump requirements (up to 40 V), and 175 °C Tj max supports under-hood ambient temperatures. However, it is not AEC-Q101 qualified; for automotive safety-critical systems, consult Infineon's AEC-Q101-qualified equivalents like IPP65R099C7.
What is the recommended PCB layout for thermal performance?
Mount the exposed drain pad directly to ≥6 cm² of 70 µm thick copper on FR4 (single layer, vertical orientation, no forced air). Use ≥4 thermal vias (0.3 mm diameter, 0.8 mm pitch) under the pad connecting to inner or backside ground planes to achieve RthJA ≈ 50 K/W.
Does SPD14N06S2-80 require a gate resistor for stability?
Yes - a 10–39 Ω series gate resistor is recommended to dampen ringing caused by gate-drain capacitance and PCB inductance. The datasheet specifies td(on)/td(off) test condition uses RG = 39 Ω; lower values increase switching speed but risk oscillation or shoot-through in bridge topologies.
Can SPD14N06S2-80 replace IRFZ44N in existing designs?
Yes, with caveats: pin-compatible in TO252 vs. TO220, but thermal design must be re-evaluated due to different RthJC (2.14 K/W vs. ~1.5 K/W) and package footprint. Also verify gate drive strength - SPD14N06S2-80's lower Qg (10 nC vs. 71 nC) reduces driver stress but may increase EMI without proper layout.
