Infineon Technologies AG Single, Pre-Biased Bipolar Transistors BCR129E6327

The BCR129 series consists of NPN silicon digital transistors with built-in bias resistors, designed for switching, inverter, and interface circuits. Available in SOT23, SOT323, and SOT363 packages, the devices feature a collector-emitter voltage rating of 50 V, a maximum collector current of 100 mA, and a total power dissipation up to 250 mW depending on the package. The input resistor is 10 kΩ with a tolerance of 7 to 13 kΩ. The junction temperature rating is 150 °C, and the devices are RoHS compliant and qualified to AEC-Q101. Thermal resistance from junction to soldering point is specified as ≤240 K/W for SOT23, ≤140 K/W for SOT363, and ≤105 K/W for SOT323.
