NX138AKR is a high performance, low voltage JFET n-channel depletion mode digital transistor. It offers features such as low on-state resistance (RDS (on)), low input capacitance (Ciss), fast switching, and low gate drive current.

This makes the NX138AKR a suitable choice for many digital applications such as CMOS logic devices, communications and power management, consumer electronics and automotive markets. The NX138AKR is offered in a variety of packages including SOT563, SOT-83 and TO-92.

The NX138AKR utilizes a depletion mode architecture, which is a type of field-effect transistor (FET) where a gate voltage above the voltage of the source causes an increase in the drain current. That is, the device will be on in its default state without the need for a certain gate voltage.

This makes the NX138AKR suitable for applications where a reliable, electrically isolated operation is required, such as level shifters, analog switches, voltage regulators, DC-DC converters, amplifier circuits, digital logic and memory devices.

The NX138AKR is designed for operation in environments with a supply voltage range from -400V to +400V and a maximum junction temperature of 125°C. It features low junction leakage current, fast switching performance and low on-resistance. This enables it to switch quickly and efficiently, with minimal power consumption.

The NX138AKR has a gate threshold voltage of -2V to ground. This indicates that it is a fully depletion-mode part, meaning the gate voltage needs to be higher than the source voltage to turn the part on. This enables the use of the part in various types of amplitude control, such as audio amplifiers, or switching regulators.

The NX138AKR also features low input capacitance, which makes it suitable for use in noise-sensitive applications. This significantly reduces the risk of noise coupling, which can cause electrical interference and degrade system performance.

The NX138AKR utilizes a HEXFET package, which includes the use of two metal layers and two polyimide layers to achieve excellent thermal and electrical performance. The HEXFET package provides a number of advantages, such as improved ruggedness, robustness and reliability, which are crucial for applications in harsh environments.

In summary, the NX138AKR is an ideal choice for a wide range of digital and analog applications. It features low RDS (on), low input capacitance, fast switching, and low gate drive current, making it suitable for a range of applications including CMOS logic devices, communications and power management, consumer electronics and automotive markets.
