Each side integrates the base-bias resistor network — R1 is 1 kΩ (NPN) and 10 kΩ (PNP), with a shared R2 of 10 kΩ — so the turn-on threshold is set without external resistors. ## 50 V NPN, 12 V PNP — watch the rail voltage The NPN side is rated for 50 V collector-emitter breakdown, but the PNP side is limited to 12 V. If your supply rail exceeds 12 V, the PNP transistor is the constraint — keep the collector voltage under 12 V or use the NPN side only. Saturation voltage is specified at 300 mV for both sides under their respective test conditions (500 µA base, 10 mA collector for NPN; 5 mA base, 100 mA collector for PNP), which is typical for pre-biased parts and leaves adequate headroom for 3.3 V logic. ## 120 mW power budget in a tiny package Maximum power dissipation is 120 mW for the whole device. In a dense SOT-563 layout with limited copper, continuous operation near the 100 mA / 500 mA limits will hit that ceiling quickly — derate for ambient temperature and check the junction temperature if both transistors are conducting simultaneously. The surface-mount SOT-563 (1.6 × 1.6 mm typical) is suited for automated assembly and reflow soldering.","metaTitle":"ROHM EMD29T2R Dual Pre-Biased Transistor, SOT-563","metaDescription":"ROHM EMD29T2R dual NPN/PNP pre-biased transistor in SOT-563, 120 mW, 50 V/12 V breakdown.
