NJW3281G Description

Short technical summary and product information.

The NJW3281G from ON Semiconductor is a high-performance NPN silicon power bipolar transistor. It is engineered for demanding applications such as high-power audio amplifiers, disk head positioners, and other linear circuits.

 

Key electrical characteristics include a maximum collector-emitter voltage (VCEO) of 250V and a continuous collector current (IC) of 15A. The transistor can handle a peak collector current of 30A and a continuous base current of 1.6A. It offers a total power dissipation of 200W at 25°C case temperature and features a DC current gain (hFE) of 75 minimum at 3A collector current and 5V VCE.

 

Designed for reliable performance at higher power levels, the NJW3281G exhibits exceptional safe operating area and excellent gain linearity. Its complementary NPN-PNP gain matching within 10% from 50mA to 5A is beneficial in complementary configurations.

 

The transistor is housed in a TO-3P-3L package, suitable for through-hole mounting. It operates within a junction temperature range of -65°C to +150°C, with a thermal resistance junction-to-case of 0.625°C/W.
