Pre-biased dual transistor with integrated 22kΩ resistors
The Infineon BCR 22PN H6727 is a pre-biased dual transistor combining one NPN and one PNP in a single SOT-363 package, each with integrated 22kΩ base and emitter-base resistors. This configuration eliminates two external resistors per channel, saving board space in high-density switching and interface circuits. The 130 MHz transition frequency supports switching applications up to several tens of MHz, and the 50 V collector-emitter breakdown voltage provides adequate headroom for 24 V and 48 V industrial logic rails.
Infineon lists the BCR 22PN H6727 as obsolete. No direct factory replacement is documented in the available records.
Package and power rating
Housed in the PG-SOT363-PO package (6-VSSOP, SC-88, SOT-363 equivalent), this surface-mount device is rated for a maximum power dissipation of 250 mW.
