**Diodes Incorporated** · Digital Transistors · SOT-363

DDC114YU-7-F 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 | COM1 | passive | Common (emitter) terminal of NPN pre-biased transistor 1, the reference side of its built-in bias resistors (R1 and R2 for DDC114YU, nominal 10kΩ and 47kΩ). |
| 2 | IN1 | input | Input (base) of pre-biased transistor 1; for DDC114YU the absolute maximum input voltage range is -6 V to +40 V. |
| 3 | OUT2 | output | Output (collector) of pre-biased transistor 2; for DDC114YU the output current is rated at 70 mA, with 100 mA peak, and the supply voltage VO is rated at 50 V maximum. |
| 4 | COM2 | passive | Common (emitter) terminal of NPN pre-biased transistor 2, the reference side of its built-in bias resistors. |
| 5 | IN2 | input | Input (base) of pre-biased transistor 2; for DDC114YU the absolute maximum input voltage range is -6 V to +40 V. |
| 6 | OUT1 | output | Output (collector) of pre-biased transistor 1; for DDC114YU the output current is rated at 70 mA, with 100 mA peak, and the supply voltage VO is rated at 50 V maximum. |
