The 180 MHz transition frequency gives it enough speed for PWM frequencies up to a few megahertz and for level translation in digital interfaces. ## 150°C junction — thermally rated for tight enclosures The EMX1T2R is rated for a maximum junction temperature of 150°C, which means it can sit in a warm ambient — inside a motor drive housing, near a power supply, or in an outdoor telecom node — without derating the collector current. The 150 mW power dissipation ceiling is the package limit; at 150 mA continuous you'll be below that, but if both transistors are conducting simultaneously, the thermal budget needs a quick check against the SOA curve in the datasheet. ROHS3 compliance is confirmed, which covers the latest EU exemption updates.","metaTitle":"ROHM EMX1T2R Dual NPN Transistor, 50V 150mA 180MHz SOT-563","metaDescription":"ROHM EMX1T2R dual NPN transistor: 50V VCEO, 150mA IC, 180MHz fT, 150°C TJ.
