AZ7042Z-E1 from Diodes Incorporated, in a TO-92-3. 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 | OUT | output | Open-collector output that pulls low when VCC falls below the detect voltage; VOL is 0.4 V max and the output sinks 20 mA at 25 °C (16 mA over -40 to 85 °C) with 0.1 µA max leakage at VCC = 18 V. |
| 2 | GND | power_in | Ground reference for the detect threshold and the output low level. |
| 3 | VCC | power_in | Supply input monitored against the detect voltage; absolute maximum is -0.3 to 20 V and the recommended supply is 18 V max. |
