PNP pre-biased transistor with integrated 47 kΩ resistors
The Infineon BCR198E6393HTSA1 is a PNP pre-biased transistor in a PG-SOT23 surface-mount package, integrating two 47 kΩ resistors — one in series with the base (R1) and one between base and emitter (R2).

This means Infineon has scheduled end-of-production, and the remaining stock in the distribution channel is the final available inventory. If this part is qualified into an active design, secure your lifetime buy quantities now to avoid a forced requalification later.
The 47 kΩ base resistor (R1) sets the base drive for a given input voltage, so the transistor saturates predictably without an external resistor. The 47 kΩ emitter-base resistor (R2) provides a defined off-state, pulling the base to emitter potential when the drive is removed, which improves noise immunity.
