The BUK7Y21-40EX is a single pole double throw (SPDT) insulated transistor specifically designed to be used in failsafe automotive applications. The BUK7Y21-40EX has a double pole double throw (DPDT) diode built in to provide the necessary insulation protection in environments where the ignition and other voltage sources can create a potential hazard. The BUK7Y21-40EX is also capable of operating over a wide range of temperatures and can handle peak inrush current conduction for up to one hour.

The BUK7Y21-40EX is a two-terminal JFET based linear device which combines the features of economical, high performance and high reliability. This FET is exceptionally well suited for powering off driver circuits and gate drivers, as well as load switching. Its thickness increases the Rds ON over traditional planar FETs. This feature eliminates the possibility of current conducting paths, as it offers both a uniform current as well as better temperature stability. The device is also highly efficient, with a typical on-state power dissipation of 43.5 mW per device at 250 mA.

The BUK7Y21-40EX is suitable for use in applications where the load requires protection against overcurrent and overheating. With an on-state current of 250mA, it can be used for automotive, industrial, and consumer electronics. The on-state current of 250mA, together with the additional insulation provided by the DPDT diode, make it an excellent choice for applications that require both overload and temperature protection. Coupled with its low power dissipation, the BUK7Y21-40EX is also well suited for applications where power efficiency is a primary consideration.

The BUK7Y21-40EX is designed to work in conjunction with external components to provide a wide range of protection features for its applications. First, the NFET current control circuit allows the device to be configured to operate in either high or low voltage mode depending upon the application requirements. In addition to this, the dual P-channel IGBTs and the built-in temperature sensors provide additional protection functions such as over-current, over-temperature, and over-voltage protection. Finally, the on-board microcontroller can further be programmed to provide advanced system monitoring and control functions.

The BUK7Y21-40EX is ideal for use in automotive, industrial, and consumer electronics applications. Its low thermal resistance and superior insulation make it an attractive choice for applications where safety and reliability are of primary concern. As such, it can be used for a variety of different purposes, such as load switching, gate driver circuits, and other applications requiring temperature protection and overload protection. Furthermore, its built-in temperature sensors and NFET current control circuit make it an ideal choice for applications that require advanced system monitoring and control functions.
