Dual PNP pre-biased with matched resistor network
The Toshiba RN2504(TE85L,F) integrates two PNP transistors with a built-in bias resistor network — 47 kOhm base resistor (R1) and 47 kOhm base-emitter resistor (R2) per side — in a single SC-74A SOT-753 package. This eliminates two external resistors per transistor from the BOM, saving board space and reducing pick-and-place cost on high-volume assemblies. The 200 MHz transition frequency means it handles low-speed switching and digital interface loads comfortably, though it is not a fast-switching part for RF or high-frequency PWM.
Package and footprint — SMV / SOT-753
Housed in the SMV package (SC-74A, SOT-753), the RN2504(TE85L,F) occupies a 2.9 mm × 1.6 mm footprint with 0.95 mm pin pitch — a standard small-signal SOT-23-5 layout. Surface-mount assembly on standard FR-4 with no special thermal management needed for the 300 mW power dissipation.
