**TECH PUBLIC** · MOSFETs · DFN5x6-8L

CSD18504Q5A-TP from TECH PUBLIC, in a DFN5x6-8L. 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 | S | passive | Source of the N-channel MOSFET (pin 1 marked by the dot), carrying up to 60 A continuous at Tc = 25°C. |
| 2 | S | passive | Source of the N-channel MOSFET, connected to the other source pins and the body diode anode. |
| 3 | S | passive | Source of the N-channel MOSFET, connected to the other source pins and the body diode anode. |
| 4 | G | input | Gate of the N-channel MOSFET, rated at ±20 V gate-source maximum with a threshold of 1 V min to 2.2 V max. |
| 5 | D | passive | Drain of the MOSFET, rated at 40 V drain-source maximum. |
| 6 | D | passive | Drain of the MOSFET, rated at 40 V drain-source maximum. |
| 7 | D | passive | Drain of the MOSFET, rated at 40 V drain-source maximum. |
| 8 | D | passive | Drain of the MOSFET, rated at 40 V drain-source maximum, with 300 A pulsed drain current. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
