Dual PNP pre-biased pair — what the bias resistors mean for the BOM
The RN2903FE(TE85L,F) packs two PNP transistors with integrated 22 kΩ base resistors (R1) and 22 kΩ emitter-base resistors (R2) into a single SOT-563 package. Those built-in bias resistors eliminate two external resistors per transistor from the BOM — four components saved on a dual-channel design. The 200 MHz transition frequency means it handles low-speed switching and logic-level interfacing without trouble.
Surface-mount in SOT-563 or SOT-666 case outline, with the supplier device package designated ES6. Cut Tape works for prototype or low-volume runs.
RoHS compliant per.
