IRF3205 N-Channel MOSFET

@@ -0,0 +1,46 @@+# IRF3205++**Infineon** · MOSFET · TO-220++The IRF3205 is a 55 V N-channel power MOSFET with low 8 mOhm on-resistance and a high 110 A current rating. Its low Rds(on) and high current handling make it a workhorse for high-current DC switching, motor drives, battery management, and synchronous rectification, in a TO-220 package.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | G | input | Gate. Insulated MOSFET control terminal; V(GS(th))=2.0-4.0 V, absolute max V(GS)=±20 V. Drives the channel between Drain and Source. |+| 2 | D | passive | Drain. Continuous drain current I(D)=110 A @ T(C)=25 °C, V(DSS)=55 V, R(DS(on))=8.0 mΩ @ V(GS)=10 V. Electrically connected to the TO-220AB metal tab. |+| 3 | S | passive | Source. Return terminal of the N-channel; integral body diode anode (V(SD)≤1.3 V, I(S)=110 A continuous, 390 A pulsed). |++## Key specifications++| Parameter | Value |+|---|---|+| Type | N-channel power MOSFET |+| Drain-source voltage (VDS) | 55 V |+| On-resistance (RDS(on)) | 8 mOhm at VGS = 10 V |+| Continuous drain current (ID) | 110 A |+| Gate threshold voltage | 2 V to 4 V |+| Power dissipation | 200 W |+| Package | TO-220 (G/D/S + tab) |+| Operating temperature | -55 C to 175 C |++## Ordering variants++- `IRF3205PbF`++## CAD (KiCad official)++- Symbol: `irf3205.kicad_sym`+- Footprint: `irf3205.kicad_mod`+- 3D model: TO-220 body from KiCad `Package_TO_SOT_THT/TO-220-3_Vertical`.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Infineon datasheet](https://www.infineon.com/dgdl/Infineon-IRF3205-DataSheet-v01_01-EN.pdf) (9 pp, sha256 `8658a274d7d8f377`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
