Complementary NPN/PNP pair in a 1.6 × 1.6 mm footprint
The ROHM EMZ7T2R packs an NPN and a PNP transistor in a single SOT-563 package, giving you a complementary pair for push-pull drivers, half-bridge gate drive, or signal-level output stages without routing two separate discretes. The 150 mW total power budget per package means you are not dissipating much; keep the duty cycle moderate or let the PCB copper do the work.
Transition frequency and saturation — where the numbers matter
Transition frequency sits at 320 MHz for the NPN side and 260 MHz for the PNP. That is fast enough for switching regulators switching at a few hundred kilohertz or for buffering a PWM fan-control signal, but not a GHz-class RF transistor — the 12 V breakdown tells you that already. Saturation voltage is 250 mV max at 200 mA collector current with 10 mA base drive, so the on-state loss stays low when you forward-bias it hard enough. The 270 minimum DC current gain at 10 mA, 2 V means you get consistent beta across the low-current region where many small-signal transistors start to droop.
The SOT-563 package is a standard ROHM small-signal footprint shared across the EMZ and EMX families, which helps if you need to dual-source or swap between complementary and dual-NPN variants on the same board layout.
