Product Description
Product Overview
The WB2003 is a high-voltage, high-current Darlington transistor array featuring seven open collector common emitter pairs, each rated at 500mA. It is designed to drive a wide range of loads including solenoids, relays, DC motors, LED displays, filament lamps, thermal print heads, and high-power buffers. The device includes suppression diodes for inductive load driving and offers inputs compatible with various logic types. Its outputs are pinned in opposition to simplify board layout. Available in DIP16, SOP16, and SSOP16 packages.
