Product details
Overview
SPD30N08S2L-21 from Infineon Technologies is an N-channel enhancement-mode logic-level power MOSFET in TO-252 (D-Pak) package, rated for 75 V VDS, 30 A continuous drain current at TC = 25 °C, and 20.5 mΩ RDS(on) at VGS = 10 V. It features avalanche rating, 6 kV/µs dv/dt capability, and 175 °C maximum junction temperature - deployed in DC-DC synchronous buck converters and motor drive half-bridges.
For engineers reviewing the SPD30N08S2L-21 datasheet, SPD30N08S2L-21 pinout, SPD30N08S2L-21 application, or SPD30N08S2L-21 equivalent, key selection criteria include RDS(on) at 4.5 V gate drive, unclamped inductive switching robustness, thermal resistance (RthJC = 0.7–1.1 K/W), and reverse diode recovery charge (Qrr = 122–153 nC).
Technical Context
This OptiMOS™ device uses trench-gate silicon technology optimized for low gate charge (Qg = 54–72 nC) and high transconductance (gfs = 23–45 S), enabling fast switching with reduced driver loss. Its logic-level threshold (VGS(th) = 1.2–2.0 V) ensures full enhancement with standard 3.3 V or 5 V microcontroller outputs.
The integrated body diode exhibits low forward voltage (VSD = 0.9–1.3 V at IF = 30 A) and controlled reverse recovery (trr = 52–65 ns, Qrr = 122–153 nC), minimizing commutation loss and ringing in hard-switched topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 75 V - supports 48 V bus systems with 50 % derating margin against transients |
| RDS(on) @ VGS = 10 V | 20.5 mΩ max - enables ≤1.5 W conduction loss at 30 A in thermally optimized PCB layout |
| RDS(on) @ VGS = 4.5 V | 26 mΩ max - ensures usable on-resistance with 3.3 V logic-level gate drive |
| Qg | 72 nC max - determines gate driver power requirement and switching speed trade-off |
| EAS | 240 mJ single-pulse - provides ruggedness against inductive load turn-off energy without external snubber |
| tr/tf | 15–24 ns / 15–23 ns - supports >500 kHz switching in high-efficiency SMPS designs |
| Qrr | 153 nC max - directly impacts crossover loss and EMI in synchronous rectification |
Pinout & Package
SPD30N08S2L-21 is housed in a surface-mount TO-252-3 (D-Pak) package with exposed drain pad for thermal performance. The package footprint complies with JEDEC MS-012AC and supports ≥6 cm² copper area for optimal heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Source) | Source terminal of N-channel MOSFET | Low-side reference node; connects to ground or low-side switch node in half-bridge |
| Pin 2 (Gate) | Control electrode | Receives logic-level PWM signal; requires <72 nC charge for full turn-on |
| Pin 3 (Drain) | Power output terminal | Connected to high-side rail or inductive load; electrically tied to exposed copper pad |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive | VGS(th) = 1.2–2.0 V enables direct interface with 3.3 V/5 V MCUs without level-shifting |
| Avalanche-rated | 240 mJ single-pulse EAS eliminates need for external clamping in inductive switching |
| dv/dt ruggedness | 6 kV/µs rating prevents false turn-on during high-slew-rate voltage transients |
| High-temperature operation | Rated up to Tj = 175 °C supports compact, fanless industrial power designs |
| Optimized body diode | Qrr = 122–153 nC and trr = 52–65 ns reduce switching loss in synchronous rectifiers |

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 |
|---|---|---|---|
| IRLR8726PbF | VDS = 75 V, RDS(on) = 20 mΩ @ 10 V, Qg = 32 nC - lower gate charge but no specified avalanche rating | Suitable for low-frequency, non-inductive loads where EAS not required | Prefer when gate drive strength is limited and avalanche stress is absent |
| STP30NF06L | VDS = 60 V, RDS(on) = 20 mΩ @ 10 V, Tjmax = 175 °C - lower voltage rating limits 48 V system margin | Acceptable in 24 V systems or with strict input transient suppression | Select only if system VIN max ≤ 40 V and board space favors TO-220 |
Compared with IRLL8726PbF and STP30NF06L, SPD30N08S2L-21 uniquely combines 75 V rating, 175 °C operation, and certified avalanche ruggedness - making it the only choice for unclamped inductive switching in 48 V industrial environments requiring long-term reliability without snubbers.

FAQ
What is the maximum continuous drain current at 100 °C case temperature?
At TC = 100 °C, the continuous drain current is derated to approximately 18 A per the ID vs. TC curve on page 4 of the datasheet. This reflects thermal limitation of the TO-252 package under real-world PCB cooling conditions, not electrical degradation.
Does SPD30N08S2L-21 require a gate resistor for stability?
Yes - a gate resistor (typically 3.9 Ω, as used in dynamic test conditions) is recommended to dampen gate oscillation and control dV/dt during switching. Lower values increase switching speed but risk ringing; higher values reduce EMI but raise switching losses.
Can this MOSFET be used in parallel configurations?
Yes - its positive temperature coefficient of RDS(on) (shown on page 9) enables inherent current sharing. However, matched layout symmetry, individual gate resistors, and Kelvin source connections are required to ensure balanced dynamic current distribution across paralleled units.
Is the body diode suitable for synchronous rectification in a 400 kHz buck converter?
Yes - with trr = 52–65 ns and Qrr = 122–153 nC, the body diode supports synchronous rectification up to 500 kHz. For best results, pair with a controller featuring adaptive dead-time control to minimize shoot-through and reverse recovery loss.
