Description
UTC D313 IS NPN EPITAXIAL PLANAR TRANSISTOR.
This transistor is designed for use in general purpose amplifier and switching applications.
Absolute maximum ratings ( Ta=25°C )
1. Collector to Base Voltage: Vcbo = 60 V
2. Collector to Emitter Voltage: Vceo = 60 V
3. Emitter to Base Voltage: Vebo = 5 V
4. Collector Current: Ic = 3 A
6. Junction Temperature: Tj = 150°C
7. Storage Temperature: Tsg = -55 ~ +150°C
1. Current Amplification: NPN transistors are designed to amplify electrical current, and can be used in a wide range of electronic applications such as amplifiers, switches, and oscillators.
2. Forward Biased: In order to operate, the base-emitter junction of an NPN transistor must be forward biased, meaning that the base must be connected to a positive voltage relative to the emitter.
