IMH20TR1G Application Field and Working Principle

IMH20TR1G, manufactured by International Rectifier, is a diode-isolated, coarse-current-sourced, pre-biased transistor array that provides an economical and efficient way to control high side and low side power devices.

The product has been developed as an interface in automotive applications that require inner insulation and direct contact of the pre-biased devices. It features an embodied isolated thermal pad that allows direct contacting to the metal core of the devices in a wide range of temperature grades.

It consists of an array of transistor elements that can be connected in either parallel or series configuration to achieve specific goals. The key features of IMH20TR1G include long off-state isolation time, low forward voltage drop due to the diode isolation, and a reduced on-state resistance.

IMH20TR1G can be applied mainly in automotive chassis-mounted electrical equipment and interior lighting systems. Other possible applications include non-mobile power converters, motor drives, and load detectors. Its working principle is based on semiconductor physics and the use of the transistor elements to preempt and control power.

In terms of working principle, this product is based on the transistor array which is composed of NPN and PNP bipolar junction transistors (BJT). It works by creating a bias voltage across the terminals of the transistor array and then use this voltage to manipulate the current flow or voltage of various devices. This manipulation is made possible by controlling the current applied to the gate terminal of the transistors.

The transistors are the active components of the product and their main goal is to control the current flow or voltage of the attached devices. This is achieved by controlling the current on their gate terminal using the bias voltage. When the current is increased, it causes the transistor to become active, which reduces the voltage across the device. Conversely, when the current is reduced, it decreases the transistor activity, causing the voltage across the device to be increased.

Overall, IMH20TR1G offers a cost-effective means of controlling high side and low side power devices. It integrates NPN and PNP bipolar junction transistors into a diode isolated pre-biased array that can be used in many applications. The application range is wide and includes automotive applications, motor drives, non-mobile power converters, and load detectors.

IMH20TR1G, a diode-isolated, coarse-current-sourced, pre-biased transistor array, has been designed and developed to interact with and control efficient operation of automotive chassis-mounted electrical equipment, interior lighting systems, motor drives, non-mobile power converters, and load detectors. The product is truly versatile, thanks to the embedded NPN and PNP types of transistor array which can control the current or voltage of various devices and their gate current value leads to changes in their activity.
