Infineon Technologies · Digital Transistors · SOT-23
BCR 135 E6327 from Infineon Technologies, in a SOT-23. 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 is the input of the built-in bias network (R1 = 10 kΩ, R2 = 47 kΩ); the datasheet gives Vi(on) of 0.5 to 1.4 V at IC = 2 mA, VCE = 0.3 V and Vi(off) of 0.5 to 1 V at IC = 100 µA, VCE = 5 V. |
| 2 | E | passive | Emitter is the common terminal of the transistor; the datasheet limits the input reverse voltage Vi(rev) to 6 V and the input forward voltage Vi(fwd) to 40 V. |
| 3 | C | passive | Collector is the output terminal, rated for VCEO of 50 V and IC of 100 mA maximum. |
