2N2102 Description

Short technical summary and product information.

The 2N2102 is a silicon NPN epitaxial planar bipolar junction transistor designed for high-current general-purpose switching and amplification. It features a maximum collector-emitter voltage (VCEO) of 65V and a continuous collector current rating of 1A. The device is housed in a hermetic TO-205AD (TO-39) through-hole metal can package, offering robust thermal performance with a maximum power dissipation of 1.0W at 25°C ambient and 5.0W at 25°C case temperature.

 

Electrical characteristics include a DC current gain (hFE) of 40-200 at 150mA and 10V, with a transition frequency (fT) of 60 MHz. Saturation voltage (VCE(sat)) is 0.5V maximum at 150mA collector current and 15mA base current. The device operates over a junction temperature range of -65°C to +200°C, making it suitable for demanding environments.

 

Typical applications include switching regulators, power drivers, and general-purpose amplifier stages where moderate voltage and current handling are required. The TO-39 package provides excellent heat dissipation and reliability for industrial and military-grade designs.
