**Infineon Technologies** · Digital Transistors · SOT-363

BCR 108S H6327 from Infineon Technologies, in a SOT-363. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | E1 | passive | Emitter of transistor 1. Ground/return leg of the first NPN digital transistor. |
| 2 | B1 | passive | Base input of transistor 1 through the internal series resistor R1 = 2.2 kΩ (with 47 kΩ base-emitter shunt R2). Input on voltage Vi(on) = 0.5 - 1.1 V, input off voltage Vi(off) = 0.4 - 0.8 V. |
| 3 | C2 | passive | Collector of transistor 2. Switched output leg of the second NPN digital transistor; VCEO = 50 V max, IC = 100 mA max, VCEsat ≤ 0.3 V at IC = 10 mA / IB = 0.5 mA. |
| 4 | E2 | passive | Emitter of transistor 2. Ground/return leg of the second NPN digital transistor. |
| 5 | B2 | passive | Base input of transistor 2 through the internal series resistor R1 = 2.2 kΩ (with 47 kΩ base-emitter shunt R2). Input on voltage Vi(on) = 0.5 - 1.1 V, input off voltage Vi(off) = 0.4 - 0.8 V. |
| 6 | C1 | passive | Collector of transistor 1. Switched output leg of the first NPN digital transistor; VCEO = 50 V max, IC = 100 mA max, VCEsat ≤ 0.3 V at IC = 10 mA / IB = 0.5 mA. |

## CAD (KiCad official)

- Symbol: `BCR 108S H6327`
- Footprint: `Package_TO_SOT_SMD:SOT-363_SC-70-6`
- 3D model: SOT-363 (KiCad packages3D, STEP)
- 3D model files: `bcr-108s-h6327-etched.step` / `bcr-108s-h6327-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bcr-108s-h6327.step` / `bcr-108s-h6327.glb` are the bare package body.
