This emitter-coupled dual configuration saves board space and external resistor count in switching and interface circuits where the bias network is fixed. Rated for 50 V collector-emitter breakdown and 100 mA continuous collector current, with a 300 mW power dissipation limit in the SMV package. The 200 MHz transition frequency means it handles moderate-speed switching up into the low-MHz range — fine for relay drivers, level shifters, and logic interface buffers. ## Package and rework reality SC-74A / SOT-753 is a small-outline package with five leads — the SMV variant is Toshiba's naming for this footprint. The 0.95 mm pitch and 2.9 x 1.6 mm body make it hand-reworkable with a fine-tip iron or hot air at 300°C, but the small pad area means the 300 mW dissipation limit is real; keep the copper pour under the part modest to avoid overheating the die during reflow. Cut Tape works for prototype or low-volume builds.","metaTitle":"Toshiba RN2505TE85LF 2 PNP Pre-Biased, 50V, 100mA","metaDescription":"Toshiba RN2505TE85LF dual PNP pre-biased transistor in SC-74A (SMV), 50V Vceo, 100mA Ic, 300mW, 200MHz ft.

The key difference is the base resistor: RN2505 uses 2.2 kΩ R1, while RN2507 uses 10 kΩ R1. The emitter-base resistor (R2) is 47 kΩ on both. If your circuit's bias network depends on the 2.2 kΩ base resistor, the RN2507 will not drop in without a resistor change."},{"question":"Will RN2505TE85LF fit the same board as RN2507(TE85L,F)?","answer":"Yes — both share the same SC-74A (SOT-753) SMV package and pinout. The footprint is identical. The electrical difference is only the base resistor value (2.2 kΩ vs 10 kΩ), so the board layout is compatible; the circuit design may need adjustment."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/toshiba/RN2505TE85LF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/toshiba/RN2505TE85LF when reusing this data.
