Dual pre-biased pair in a SOT-363
The Infineon BCR22PNH6327XTSA1 packs one NPN and one PNP pre-biased transistor into a single PG-SOT363-PO package — a space-saving alternative to two discrete bias-resistor networks for switching and driver stages where board area is tight. Both the base resistor (R1) and the base-emitter resistor (R2) are 22kOhms, giving a symmetrical input impedance that simplifies design-in for logic-level interface or relay/load driver circuits.
For existing production, you can still source it through independent distribution against an RFQ, but new designs should look at the current Infineon dual pre-biased transistor portfolio for a pin-compatible alternative.
