# CSD19501KCS

**Texas Instruments** · MOSFETs · TO-220

CSD19501KCS from Texas Instruments, in a TO-220. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Gate | input | Gate terminal of the MOSFET, with gate-to-source voltage rated at ±20 V absolute maximum (VGS). |
| 2 | Drain | passive | Drain terminal of the MOSFET, rated for 80 V drain-to-source voltage (VDS) and 129 A continuous drain current when silicon-limited at TC = 25°C (100 A package-limited). |
| 3 | Source | passive | Source terminal of the MOSFET, serving as the reference for the gate-to-source voltage rating; the datasheet gives no further explicit limit for this pin. |
