Diodes Incorporated · Digital Transistors · SOT-523
DDTC113TE-7-F from Diodes Incorporated, in a SOT-523. 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 | B | input | Base, which drives the transistor through the built-in 1kΩ (nominal, ±30%) series resistor R1 for DDTC113TE, with VEBO limited to 5 V maximum. |
| 2 | E | passive | Emitter of the NPN transistor, with emitter-base voltage limited to 5 V maximum. |
| 3 | C | passive | Collector of the NPN transistor, rated for VCEO 50 V, VCBO 50 V and IC(MAX) 100 mA. |
