2N5550 Description

Short technical summary and product information.

The 2N5550 is an NPN silicon bipolar junction transistor designed for general purpose amplifier and switching applications. It is manufactured by On Semiconductor and is part of the 2N5550/2N5551 series of preferred devices.

 

Key electrical specifications include a maximum collector-emitter voltage (VCEO) of 140V, a continuous collector current rating of 600mA, and a minimum DC current gain (hFE) of 60 at Ic=10mA, Vce=5V. The transistor features a typical transition frequency of 300MHz and a collector-emitter saturation voltage of 250mV at Ib=5mA, Ic=50mA.

 

The device is housed in a through-hole TO-92 package (TO-226-3, TO-92-3 Long Body) and supports a total power dissipation of 625mW at 25°C ambient temperature. The operating junction temperature range is -55°C to +150°C, making it suitable for a wide range of environments.

 

Design engineers should consider the thermal derating of 5.0mW/°C above 25°C and ensure adequate heat sinking for continuous operation near maximum ratings. The low saturation voltage and high transition frequency enable efficient switching and amplification in low-to-medium power circuits.
