Dual pre-biased pair in a single SOT-363
The Infineon BCR22PNH6433XTMA1 integrates one NPN and one PNP pre-biased transistor in a single SOT-363 package. Each transistor includes internal 22 kΩ base and 22 kΩ emitter-base resistors, so the bias network is built in — no external resistors needed for the base drive. This saves board area and reduces component count in switching and driver stages where you need complementary outputs.
50 V breakdown, 100 mA collector current
Collector-emitter breakdown is rated at 50 V, with a maximum continuous collector current of 100 mA per transistor. The 130 MHz transition frequency keeps switching edges clean for low-speed to moderate-speed loads like relay drivers, LED indicators, or logic-level translation.
NRND — plan your BOM accordingly
It remains available for existing production runs through independent distribution, but new designs should evaluate a current-production alternative. The base product number BCR22 family includes other dual pre-biased variants that may suit your footprint and bias requirements — verify pin compatibility and resistor values against your schematic before substituting.
