That means one component replaces two discrete transistors plus four resistors — a common trick for cutting pick-and-place cost and board area on digital outputs, relay drivers, and logic-level interface circuits where you need a simple inverter or buffer stage. Each transistor is rated for 50 V collector-emitter breakdown and 100 mA continuous collector current, with a maximum power dissipation of 150 mW for the whole package. The 250 MHz transition frequency keeps switching edges clean up through low-MHz gate drives and serial bus buffers. ## Still in production — no end-of-life scramble ROHM lists the EMG9T2R as active with current lifecycle stage. ## Package and mounting With R1 = R2 = 10kΩ, the base is biased at roughly half the collector supply through the resistor divider when the input is high. The 10kΩ base resistor limits base current from the logic output, so the transistor saturates at about 300 mV with 500 µA base drive into a 10 mA load. The DC current gain minimum of 30 at 5 mA, 5 V means you get reliable saturation even with the built-in base resistor dropping some drive. Off-state leakage is capped at 500 nA, which keeps the output high-impedance when the input is low — no unintended pull-downs on a shared bus.","metaTitle":"EMG9T2R dual NPN pre-biased transistor, 250 MHz, 150 mW","metaDescription":"ROHM EMG9T2R dual NPN pre-biased transistor array. 50 V VCEO, 100 mA IC, 10kΩ base and emitter resistors. 250 MHz transition frequency.
