# LN2670TZHG

**LRC** · MOSFETs · SOT-89

LN2670TZHG from LRC, in a SOT-89. 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 | MOSFET gate terminal; the datasheet rates gate-to-source voltage VGS at ±20 V. |
| 2 | Drain | passive | MOSFET drain terminal; the datasheet rates drain-to-source voltage VDSS at 60 V. |
| 3 | Source | passive | MOSFET source terminal, the reference for gate drive and the drain-source rating (VDSS 60 V). |
