# 2SC5103TLQ

**ROHM Semicon** · Bipolar Transistors - BJT · TO-252-2(DPAK)

2SC5103TLQ from ROHM Semicon, in a TO-252-2(DPAK). 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 (Gate) of the NPN transistor; VEBO max is 5 V and collector current is controlled by IC/IB conditions such as 3A/0.15A. |
| 2 | C | passive | Collector (Drain) of the transistor; VCBO 100 V, VCEO 60 V, IC max 5 A DC and 10 A pulse. |
| 3 | E | passive | Emitter (Source) of the transistor; VEBO max 5 V, common return for the collector current. |
