# JSM601

**JSMSEMI** · Linear Hall Sensors · SOT-23

JSM601 from JSMSEMI, in a SOT-23. 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 | VDD | power_in | Supply pin; the datasheet specifies an operating supply of 3 V to 12 V, with an absolute maximum of 15 V. |
| 2 | GND | power_in | Ground pin for the sensor. |
| 3 | Vout | output | Analog output whose voltage changes proportionally with the magnetic field input and whose quiescent level is set by VDD; output current is rated 0 to 5 mA absolute maximum, with a 200 kOhm minimum load resistance specified for the stated test condition. |

## CAD (KiCad official)

- Symbol: `JSM601`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `jsm601-etched.step` / `jsm601-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `jsm601.step` / `jsm601.glb` are the bare package body.
