The Infineon BCR133SH6433XTMA1 integrates two NPN transistors with 10kΩ series base resistors and 10kΩ emitter-base resistors in a single SOT-363 package. This pre-biased configuration eliminates two external resistors per channel, saving board space in high-density switching arrays. The 50V collector-emitter breakdown and 100mA continuous collector current suit it for driving relays, LEDs, or logic-level loads from a 3.3V or 5V microcontroller output.

Frequently asked questions
What replaces BCR133SH6433XTMA1?
No official replacement order code is provided by Infineon. A functionally similar dual pre-biased NPN transistor in the same SOT-363 footprint should be evaluated for switching performance, saturation voltage, and thermal characteristics before substitution.
