The MJE340 is a silicon NPN bipolar transistor in a TO-126 package, designed for high-voltage general-purpose applications such as audio power amplifiers and high-voltage converters. It has a collector-emitter voltage rating of 300 V and a continuous collector current of 500 mA. The device dissipates up to 20 W at 25°C, with a derating of 0.16 W/°C above that temperature. The junction temperature range is -65°C to +150°C, and thermal resistance from junction to case is 6.25°C/W. The DC current gain ranges from 30 to 240 at a collector current of 50 mA and collector-emitter voltage of 10 V. Physical dimensions include a maximum height of 13.0 mm and a lead spacing consistent with TO-126 mounting. No environmental or safety standards are stated.
