ADC144EUQ-13 from Diodes Incorporated, in a SOT-363. 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 | E1 | passive | Emitter of transistor 1 (NPN, R1/R2 = 47kΩ/47kΩ pre-biased); the datasheet does not label pin names, so this is inferred from the device schematic. |
| 2 | B1 | input | Base/input of transistor 1 through built-in 47kΩ R1; input voltage rated -10 to +40 V, with Vl(off) 0.5 V min and Vl(on) 3.0 V max. |
| 3 | C2 | passive | Collector/output of transistor 2; collector supply rated 50 V and output current 100 mA maximum. |
| 4 | E2 | passive | Emitter of transistor 2 (NPN, 47kΩ/47kΩ pre-biased); the datasheet does not label pin names, so this is inferred from the device schematic. |
| 5 | B2 | input | Base/input of transistor 2 through built-in 47kΩ R1; input voltage rated -10 to +40 V. |
| 6 | C1 | passive | Collector/output of transistor 1; collector supply rated 50 V and output current 100 mA maximum. |
