DTC114EUBHZGTL

DTC114EUBHZGTL Application Field and Working Principle

The DTC114EUBHZGTL is a single pre-biased transistor from the bipolar junction transistor (BJT) family. It is a potentiometer-controlled diffusion transistor with an integrated reversed monolithic n-channel DMOS input/output (I/O). The pre-biased feature makes it significantly easier to design an application circuit, as no additional biasing resistors are needed.

Characteristics

The DTC114EUBHZGTL has a 0.2A current capability, with an on-resistance of 0.85 Ω, a 4V-to-16V gate voltage range and a 0.1V-to-3.3V drain to source voltage range. It also has an operating temperature range of -55°C to +125°C, maximum RMS current is 3A, board area is 2.6 mm2 and a protection capability against external power-supply transients up to 10V for tp = 10ms.

Basic Operating Principle

The DTC114EUBHZGTL transistor operates by creating a voltage drop across the transistor base (I/O) when an applied voltage is greater than the gate voltage. This allows the current flow from the drain to the source. When no voltage is applied, the transistor acts as an open circuit. The current flow is proportional to the gate voltage.

Current Path

The current flow path of the DTC114EUBHZGTL is from the source to the drain when the gate voltage is greater than the source. When the source voltage is greater than the gate voltage, then the current flow is reversed, from the drain to the source. This allows the transistor to act as either a switch, or as a current amplifier.

Applications

The DTC114EUBHZGTL has a wide range of potential applications. It can be used as an amplifier and/or switch, for controlling voltage in a circuit, and as a pre-biased device, which means no additional biasing is required. It can also be used to regulate the current in a circuit and as a voltage-to-current converter. Additionally, it can be used as a device to sense temperature, humidity and/or light.

Conclusion

The DTC114EUBHZGTL is a single pre-biased transistor from the bipolar junction transistor family. It has a 0.2A current capability, a 0.85 Ω on-resistance and a 4V-to-16V gate voltage range. It has a wide range of applications, such as amplifiers, switches, current regulators and voltage-to-current converters. Additionally, it can be used to sense temperature, humidity and/or light.
