Each transistor integrates a 47kΩ base resistor (R1) and a 47kΩ emitter-base resistor (R2), eliminating the need for external bias components in low-current switching and interface applications. Collector-emitter breakdown is rated at 50V, with a maximum collector current of 100mA per transistor — enough for driving relay coils, LED indicators, logic-level translation, or as a small-signal inverter pair. ## 150 mW total — watch the thermal budget The total power dissipation for the package is 150mW. That ceiling applies to the sum of both transistors under continuous operation. In a 50V, 100mA switching application the instantaneous dissipation can spike above that if the load is inductive or the switching edge is slow — derate per the SOT-563 thermal resistance. The 250MHz transition frequency means it handles fast edges for a small-signal part, but the 150mW limit keeps it out of linear-regulator service.","metaTitle":"EMD12T2R Dual NPN/PNP Pre-Biased Transistor, 50V, 100mA","metaDescription":"EMD12T2R dual complementary pre-biased transistor: 50V Vce, 100mA Ic, 250MHz fT, 47kΩ resistors in SOT-563.

That changes the base-drive threshold — the EMD12T2R is the higher-impedance input choice. For a dual-NPN-only variant, see the EMG2T2R; for dual-PNP-only, the EMB2T2R. None are direct pin-for-pin replacements without checking the bias resistor values against the circuit."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/rohm/EMD12T2R","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/rohm/EMD12T2R when reusing this data.
