Digital transistor

Circuit symbol, NPN

As digital transistor in which it is electronics , a discrete bipolar transistor with built-in resistors, a common base series and often denoted by additional base-emitter resistor. The area of ​​application is in the low power range.

The integrated resistors have the advantage that the digital transistor in without additional external resistor circuit as a switching transistor digital technology can be used. Compared to field-effect transistors which are voltage-controlled and in many cases do not require a series resistor, Digital transistors have the advantage even with very small control voltages below 1  V are used to.

Digital transistors include the DRC2523Y , a digital NPN transistor, and the complementary DRA2523Y as a PNP transistor, both from Panasonic .
