ULN62003A DMOS Arrays Diodes Incorporated ULN62003A DMOS Arrays are high-voltage, high-current transistor arrays, including seven open-drain devices, with all the sources connected to a common ground. The 500mA transistors provide a clamp diode, each enabling protection for driving inductive loads. The DMOS output construction features a lower on-resistance than the common bipolar devices reducing power dissipation. This also allows the designer more flexibility to control additional devices and maintain the desired die temperature.
