Central Semiconductor Corp. Single Bipolar Transistors 2N3947 TIN/LEAD

The 2N3947 is a silicon NPN transistor in a TO-18 package for general-purpose applications, with a collector-emitter voltage rating of 40 V, continuous collector current of 200 mA, and power dissipation of 360 mW at 25°C. The device has a collector-base voltage of 60 V, emitter-base voltage of 6.0 V, and operating junction temperature range of -65 to +200°C. Thermal resistance from junction to case is 146 °C/W and junction to ambient is 486 °C/W. Current gain (hFE) ranges from 40 to 300 depending on collector current. Transition frequency is 300 MHz at 10 mA and 20 V. The TO-18 case has three leads: emitter, base, and collector. The part meets RoHS compliance when ordered with the PBFREE suffix, and tin/lead plating is available with the TIN/LEAD suffix.
