PNP pre-biased transistor — where the resistor network saves you two passives
The Infineon BCR192E6327HTSA1 is a PNP pre-biased transistor in a PG-SOT23 package. The 22 kOhms base resistor (R1) and 47 kOhms emitter-base resistor (R2) are integrated on-die, so you drop two external resistors from the BOM — a clean fit for dense boards where every 0402 counts. Rated for 50 V collector-emitter breakdown and 100 mA continuous collector current, with a transition frequency of 200 MHz. The 300 mV Vce(sat) at 10 mA / 500 µA base drive keeps conduction loss low enough for 3.3 V logic-level switching without a heatsink. Power dissipation is 200 mW maximum — adequate for signal-level switching, interface pull-down, and small-signal load-switch roles in consumer, industrial, and telecom PCBs. The 100 nA collector cutoff current (ICBO) means negligible leakage in the off-state.
This exact suffix (BCR192E6327HTSA1) carries an official Last Buy lifecycle status. That means Infineon has scheduled end-of-production for this specific ordering code; once the final shipments clear, no new factory orders will be accepted. If this transistor is locked into your current BOM, the window to secure lifetime-buy quantities is open now. For ongoing production, you will need to evaluate a pin-compatible pre-biased PNP from the same or another family — or requalify the board with a different resistor ratio. We can source remaining factory stock and qualified surplus against an RFQ.
