Minimum DC current gain of 100 at 150 mA, 10 V means the part drives moderate base-drive loads without excessive input current — a typical saturated switch in a 24 V control loop or relay driver lands well inside the safe operating area. ## Junction temperature range and what it enables The -65 °C to 200 °C junction temperature rating places this part in the military-temperature class — it sustains operation in avionics bay ambient, engine-mounted electronics, or downhole instrumentation where commercial or even industrial parts would hit the thermal ceiling. Vce saturation is 1.6 V maximum at 50 mA base drive and 500 mA collector current — the on-state voltage drop at the rated current gives a rough conduction loss of 0.8 W at 500 mA, which stays within the 500 mW power dissipation limit only if the duty cycle is pulsed or the ambient is well below the maximum. ## Active production and compliance flag The part is marked RoHS non-compliant — the die-attach or lead finish likely contains lead. If your BOM requires RoHS exemption 7(c)-I (lead in high-melting-temperature solders) or you are building to a military/hermetic spec that explicitly exempts lead, this is not a blocker; for commercial RoHS-mandated builds, verify your exemption coverage before committing the line. ## Leakage and gain — what they mean for the circuit Collector cutoff current is 50 nA maximum — low enough that a 10 kΩ pull-up to 60 V sees less than 0.5 mV of leakage-induced offset, making the part suitable for high-impedance analog switches or low-power keep-alive circuits where every microamp counts.","metaTitle":"Microchip 2N2907AUB PNP Transistor, 60V 600mA UB","metaDescription":"Active PNP switching transistor, 60V Vceo, 600mA Ic, hFE 100 min at 150mA.
