Central Semiconductor Corp. Single Bipolar Transistors CMST3904 BK PBFREE

NPN silicon transistor for small signal amplification and switching, housed in an SOT-323 surface mount package. It has a collector-emitter voltage rating of 40 V, a continuous collector current of 200 mA, and a power dissipation of 275 mW. The transistor operates with a junction temperature range of -65 to +150 °C and has a thermal resistance of 455 °C/W. Current gain (hFE) ranges from 30 to 300 depending on collector current, with a transition frequency of 300 MHz. Collector-emitter saturation voltage is 0.20 V at 10 mA and 0.30 V at 50 mA.
