This integration eliminates two external resistors per transistor, cutting placement cost and board area in dense automotive I/O, relay-driver, or solenoid-driver stages. Rated for 500 mA continuous collector current and 50 V collector-emitter breakdown, it handles the typical load currents of automotive auxiliary loads — small relays, LEDs, logic-level solenoids — without an external driver transistor. ## Automotive-grade qualification and switching performance The BCR555E6433 carries AEC-Q101 qualification, placing it in the automotive-grade bin for under-hood and cabin electronics where temperature cycling and reliability screening are mandatory. Transition frequency of 150 MHz ensures clean switching well into the hundreds of kilohertz, with a typical DC current gain of 70 at 50 mA, 5 V. Saturation voltage is 300 mV at 2.5 mA base, 50 mA collector — low enough to keep dissipation under the 330 mW power limit in the SOT-23 footprint.","metaTitle":"Infineon BCR555E6433 PNP Pre-Biased Transistor, 500 mA, 50 V","metaDescription":"Infineon BCR555E6433 PNP pre-biased transistor, 500 mA collector current, 50 V breakdown, 150 MHz transition frequency.
