# JSM463

**JSMSEMI** · Hall Sensor · SOT-23

JSM463 from JSMSEMI, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD | power_in | Power supply input, 2.5 V to 5.5 V (absolute max 6.0 V). Bypass with 2.2 uF (C1) to GND per typical application circuit. |
| 2 | VOUT | output | CMOS push-pull switch output. Drives high (VDD-0.2 V at -1 mA) or low (0.2 V at 1 mA) based on magnetic field polarity/strength; Bop typ +/-17 G, Brp typ +/-12 G. Absolute max 6.0 V, +/-5 mA. |
| 3 | GND | power_in | Ground / 0 V reference. |

## CAD (KiCad official)

- Symbol: `JSM463`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `jsm463-etched.step` / `jsm463-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `jsm463.step` / `jsm463.glb` are the bare package body.
