The Infineon BCR22PNE6433HTMA1 packs one NPN and one PNP pre-biased transistor into a single 6-pin SOT-363 package. Each transistor has a 22kΩ resistor in series with the base and another 22kΩ resistor from base to emitter, so the bias network is already on-die — no external resistors needed for the typical switching or driver stage. Collector-emitter breakdown is rated at 50V, continuous collector current at 100mA, and the transition frequency hits 130MHz. The 250mW power limit is the package ceiling; in a dense board layout that SOT-363 footprint keeps the pair smaller than two discrete SOT-23s side by side.
That means Infineon has stopped production; there is no last-time-buy window still open. The base product number is BCR22PN, and the suffix E6433HTMA1 denotes the specific reel and packaging variant. No official successor is listed on the lifecycle record, so a pin-compatible drop-in replacement from Infineon's current portfolio would need to be validated against the original footprint and bias resistor values.

The SOT-363 package is common enough that a qualified second-source search should start with other dual pre-biased transistor families that share the same 22kΩ/22kΩ resistor divider and pinout, but no official cross-reference is recorded in the lifecycle data.
