Each transistor has a 10kΩ resistor in series with the base and a 10kΩ resistor from base to emitter, so the pair turns on when the base drive exceeds about 0.7 V at the input node — no external base resistors needed. Collector-emitter breakdown is rated at 50 V, continuous collector current at 100 mA, and the 250 MHz transition frequency supports switching applications up into the low-MHz range. Total package dissipation is 150 mW, which sets the thermal budget in a dense layout. ## Package and footprint fit The UMA9NTR is supplied in a surface-mount UMT5 package (also designated 5-TSSOP, SC-70-5, SOT-353). The five-pin footprint is shared across ROHM's UMT5 pre-biased transistor family, so the same PCB land pattern works for both PNP and NPN variants. Shipping options include Tape & Reel and Cut Tape. ## Lifecycle and compliance The part is RoHS3 compliant.","metaTitle":"UMA9NTR dual PNP pre-biased transistor, 50V 100mA 250MHz","metaDescription":"UMA9NTR dual PNP pre-biased transistor pair in UMT5 package. 50V Vce, 100mA Ic, 250MHz fT, 10kΩ integrated resistors.

Both share the same UMT5 package, 50 V breakdown, 100 mA collector current, and 250 MHz fT. The key difference is polarity: UMA9NTR uses two PNP transistors, while UMH9NTN uses two NPN transistors. They are not pin-compatible substitutes for each other — the circuit must be designed for the correct polarity. For a PNP-to-PNP alternative, the EMG9T2R is a dual PNP pre-biased pair with identical 10kΩ R1 and R2 values, same package, and same 150 mW power dissipation."},{"question":"What compliance documentation does ROHM provide for UMA9NTR?","answer":"The UMA9NTR is RoHS3 compliant.
