MJE340G Description

Short technical summary and product information.

The MJE340G is a plastic medium-power NPN silicon transistor from ON Semiconductor, suitable for high-voltage general-purpose applications. It is particularly useful for transformerless, line-operated equipment due to its high voltage rating.

 

Key electrical specifications include a continuous collector current of 500 mA and a collector-emitter voltage of 300 Vdc. The DC current gain (hFE) ranges from 30 to 240 at 50 mA collector current and 10V collector-emitter voltage. The device offers a high power dissipation rating of 20 W at 25°C case temperature.

 

This transistor operates within a junction and storage temperature range of -65°C to +150°C. It is housed in a TO-126 package, suitable for through-hole mounting. The MJE340G is also noted as being Pb-Free and RoHS Compliant.

 

Its complementary part is the MJE350. The MJE340G is useful in applications requiring high voltage handling and moderate current capabilities.
