Product details
Overview
SPD22N08S2L-50 from Infineon Technologies is an N-channel enhancement-mode logic-level power MOSFET rated for 75 V VDS, 25 A continuous drain current at TC = 22 °C, and 50 mΩ RDS(on) at VGS = 10 V / ID = 11 A. It features avalanche rating, 6 kV/µs dv/dt capability, and 175 °C maximum junction temperature-designed for high-reliability DC-DC converter primary-side switching in industrial power supplies.
For engineers reviewing the SPD22N08S2L-50 datasheet, SPD22N08S2L-50 pinout, SPD22N08S2L-50 application, or SPD22N08S2L-50 equivalent, key selection criteria include its logic-level gate drive compatibility (VGS(th) = 1.2–2.0 V), low RDS(on) at 4.5 V (48–65 mΩ), integrated body diode with 44–55 ns trr, and TO252-3 package thermal resistance of 1.34 K/W (typ) junction-to-case.
Technical Context
This OptiMOS™ device uses trench-gate superjunction technology to achieve low conduction loss while maintaining fast switching performance. Its 640–850 pF Ciss, 124–165 pF Coss, and 49–74 pF Crss support efficient hard-switched operation up to several hundred kHz in synchronous rectification and motor control half-bridges.
The MOSFET's 25 nC total gate charge (Qg) and 3.3 V gate plateau voltage enable predictable turn-on/turn-off timing with standard gate drivers. Its 94 mJ single-pulse avalanche energy (EAS) and 7.5 mJ repetitive rating provide robustness against inductive load transients without external snubbers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS Rating | 75 V - supports 48 V nominal bus systems with 50 % safety margin for surge and ringing |
| RDS(on) @ 10 V | 38–50 mΩ - enables <1.2 W conduction loss at 22 A in TO252 package at 25 °C |
| RDS(on) @ 4.5 V | 48–65 mΩ - ensures full enhancement with 3.3 V or 5 V logic-level microcontroller outputs |
| Qg Total | 25–33 nC - determines gate driver current requirement (~1.5 A peak for 20 ns rise time) |
| tr/tf | 22–33 ns / 18–27 ns - supports >500 kHz switching in compact SMPS designs |
| EAS | 94 mJ - withstands worst-case inductive energy dump without failure in unclamped inductive loads |
| Tj max | 175 °C - allows operation in sealed enclosures or high-ambient industrial environments |
Pinout & Package
SPD22N08S2L-50 is housed in a surface-mount TO252-3 (DPAK) package with exposed drain pad for thermal management. The package has 3 terminals: Gate (G), Drain (D), Source (S).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Left) | Gate (G) | Control terminal; requires ≤±20 V drive; threshold 1.2–2.0 V enables direct MCU interface |
| Pin 2 (Middle) | Drain (D) | High-side switch node; connected to PCB copper pour for thermal dissipation (RthJC = 1.34 K/W typ) |
| Pin 3 (Right) | Source (S) | Power return path; tied to ground or low-side switch source; defines reference for gate drive |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive | VGS(th) = 1.2–2.0 V ensures full enhancement with 3.3 V or 5 V controllers without level-shifting |
| Avalanche-rated | 94 mJ single-pulse EAS eliminates need for external clamping in relay or solenoid drive circuits |
| dv/dt ruggedness | 6 kV/µs rating prevents false turn-on during high-slew-rate commutation in half-bridge topologies |
| Integrated body diode | 44–55 ns trr and 0.9–1.3 V VSD support synchronous rectification in buck converters |
| High-temperature operation | Rated for continuous use up to 175 °C junction temperature in sealed or convection-limited enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel logic-level power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IPB050N08N3 G | RDS(on) = 4.8 mΩ @ 10 V (lower), but TO263 package; higher cost and larger footprint | Better efficiency in high-current, space-unconstrained designs; not drop-in compatible due to package | Select when RDS(on) reduction justifies board area and cost increase |
| IRLR024ZPBF | RDS(on) = 45 mΩ @ 10 V, but only 55 V VDS; lower EAS (52 mJ); TO252-3 pin-compatible | Limited to ≤40 V systems; less robust under overvoltage transients | Acceptable for cost-sensitive 24 V applications where 75 V margin is unnecessary |
Compared with IPB050N08N3 G and IRLR024ZPBF, SPD22N08S2L-50 uniquely balances 75 V rating, logic-level drive, TO252-3 footprint, and 94 mJ avalanche capability-making it optimal for industrial 48 V power stages requiring reliability without package redesign.

FAQ
What is the maximum continuous drain current at 100 °C case temperature?
At TC = 100 °C, the maximum continuous drain current is 18 A per the datasheet's ID vs. TC curve (Page 4, Figure 2). This derating accounts for thermal resistance and safe junction temperature limits, ensuring reliable operation without exceeding 175 °C Tj.
Does SPD22N08S2L-50 require a gate resistor for stability?
Yes-a gate resistor (typically 5–15 Ω) is recommended to dampen ringing caused by gate loop inductance and MOSFET input capacitance. The 25–33 nC Qg and 640–850 pF Ciss make it susceptible to oscillation without proper gate control, especially in high-speed switching layouts.
Can this MOSFET replace a standard 60 V part in a 48 V system?
Yes-its 75 V VDS rating provides 56 % headroom above 48 V nominal, accommodating typical bus transients (e.g., ISO 7637-2 Pulse 1/2/5a) and layout-induced overshoot. The 6 kV/µs dv/dt rating further ensures immunity to false turn-on during fast voltage transitions.
Is the body diode suitable for synchronous rectification?
Yes-the body diode has 44–55 ns reverse recovery time (trr) and 66–83 nC Qrr, enabling use in synchronous buck topologies up to ~300 kHz. However, for highest efficiency, an external Schottky diode may be preferred in high-frequency, high-current designs due to lower forward voltage.
