# AH1895-Z-7

**Diodes Incorporated** · Magnetic Sensors · SOT-553-5

AH1895-Z-7 from Diodes Incorporated, in a SOT-553-5. 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 | Power supply input, operating over 1.6V to 3.6V. |
| 2 | NC | unconnected | No connection, not connected internally; this pin can be left open or tied to ground. |
| 3 | NC | unconnected | No connection, not connected internally; this pin can be left open or tied to ground. |
| 4 | GND | power_in | Ground pin. |
| 5 | OUTPUT | output | Output is pulled low when the magnetic flux density exceeds the operate point (Bop) and is held until it falls below the release point (Brp); output current (source and sink) is rated at 3.5 mA absolute maximum. |
