DDTA114GKA-7-F

Transistors - Bipolar (BJT) - Single, Pre-Biased

The DDTA114GKA-7-F is a PNP pre-biased (also known as “PNP-N”) transistor belonging to the Transistors – Bipolar (BJT) – Single, Pre-Biased family. It is essentially a single transistor with two junctions, both of which are biased in the Forward direction. This type of transistor is designed for small-signal amplification and switching in a wide variety of applications.

It consists of two junctions, a PNP and an NPN, which are connected back-to-back to produce a single transistor. The PNP side of the transistor is known as the “Reverse-biased” side and the NPN side is known as the “Forward-biased” side. These two sides are pre-connected and set up to function as a single transistor.

DDTA114GKA-7-F is rated at 20V and has a current gain of 75, making it suitable for use in amplifying small signals. As the current gain is relatively low, this transistor works best in low-frequency applications. It also has a relatively low power dissipation of 250mW which makes it very suitable for low-power applications.

The common applications of the DDTA114GKA-7-F transistor are in audio amplifiers, mixers, signal conditioning, and other low-frequency amplifying and switching circuits. It is an ideal choice for applications that require a low-cost, low-power, small-signal amplifier or switch.

The working principle of the DDTA114GKA-7-F is quite simple. It acts as an amplifier for small signals and as a switch for larger signals. On the Reverse-biased side, a small signal applied to the base of the PNP is amplified as current flows through the PNP to the collector, while on the Forward-biased side, a larger signal applied to the base of the NPN switches the NPN transistor to its on or off state.

In conclusion, the DDTA114GKA-7-F is a versatile PNP-N pre-biased single transistor that is suitable for low-frequency small-signal amplification and switching applications. It is designed for a wide range of applications such as audio amplifiers, mixers, signal conditioning, and other low-frequency amplifying and switching circuits. Its working principle is quite simple, as it amplifies small signals while switching large signals.
