MC1413BDG

MC1413BDG Description

The MC1413BDG from onsemi is a high-performance 7-channel NPN Darlington transistor array designed for medium-power switching and amplification applications. Housed in a 16-pin SOIC package, this device integrates seven Darlington pairs with high current gain (hFE ≥ 1000 @ 350mA, 2V) and a collector-emitter breakdown voltage of 50V, making it suitable for driving inductive loads such as relays, solenoids, and stepper motors. With a maximum collector current (Ic) of 500mA per channel and a low Vce saturation voltage (1.6V @ 500µA, 350mA), it ensures efficient power handling with minimal losses. The device is RoHS-compliant and rated for operating temperatures up to 150°C (TJ), ensuring reliability in demanding environments.
