MC1413DG Description

The MC1413DG 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, it integrates seven Darlington pairs with common emitters, offering a collector-emitter breakdown voltage (VCEO) of 50V and a maximum collector current (Ic) of 500mA per channel. This device is optimized for low input drive requirements, with a minimum DC current gain (hFE) of 1000 at 350mA and 2V, ensuring efficient signal amplification. Its low saturation voltage (1.6V max at 500µA, 350mA) enhances power efficiency, making it suitable for high-density, low-power designs.
