Changjing · Digital Transistors · SOT-563
EMB9 from Changjing, in a SOT-563. 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 PNP digital transistor Tr1 (DTA114Y with built-in R1/R2); Vi -40 to +6 V, VCC max -50 V. |
| 2 | B1 | input | Input (base via built-in resistor R1, 7 to 13 kΩ) of Tr1; input voltage range -40 to +6 V, Vi(on) max -1.4 V. |
| 3 | C2 | passive | Collector (output) of PNP digital transistor Tr2; output current max -100 mA, VCC max -50 V. |
| 4 | E2 | passive | Emitter of PNP digital transistor Tr2 (DTA114Y with built-in R1/R2); the two transistor elements are independent. |
| 5 | B2 | input | Input (base via built-in resistor R1, 7 to 13 kΩ) of Tr2; input voltage range -40 to +6 V, Vi(on) max -1.4 V. |
| 6 | C1 | passive | Collector (output) of PNP digital transistor Tr1; output current max -100 mA, VCC max -50 V. |
