Each transistor has a 10 kΩ base resistor (R1) and a 47 kΩ base-emitter resistor (R2), so the pair is self-biased and ready to switch from a logic-level output without external resistors. Collector-emitter breakdown is rated at 50 V, with a maximum collector current of 100 mA per transistor. ## Switching speed and drive capability Transition frequency of 250 MHz means these transistors can handle load switching well into the VHF band — useful for gating RF signals or driving small relays at high repetition rates. The 150 mV saturation voltage at 5 mA collector current keeps conduction losses low in logic-level shifting or LED drive applications. ## Package and footprint reality SOT-563 is a very small package — about 1.6 mm × 1.6 mm — so the PCB footprint is tight. The EMT6 supplier device package is the same outline. ## Sourcing and compliance ROHS3 compliant.","metaTitle":"EMB59T2R dual PNP pre-biased transistor, SOT-563, 250 MHz","metaDescription":"ROHM EMB59T2R dual PNP digital transistor with 10k/47k bias resistors. 100 mA Ic, 150 mW, 250 MHz ft.
