MC1413DG

Overview

The MC1413DG is a high-voltage, high-current Darlington transistor array manufactured by onsemi. It integrates seven NPN Darlington-connected transistors within a single SOIC-16 package. Each channel includes an internal 2.7 kΩ series input resistor, facilitating direct interfacing with 5.0 V TTL or CMOS logic circuits without external components. The device features a maximum collector-emitter voltage of 50 V and supports continuous collector currents up to 500 mA per output. Internal suppression diodes are incorporated to manage inductive load flyback voltages. The component operates within an ambient temperature range of -20°C to +85°C and utilizes a Pb-Free packaging configuration.

Feature Summary

• Integrates seven independent NPN Darlington pairs with built-in 2.7 kΩ base resistors for simplified logic interfacing
• Includes internal clamp diodes to protect against voltage spikes generated by inductive loads such as relays and solenoids
• Supports peak inrush currents sufficient for driving incandescent lamps and printer hammers
• Provides high breakdown voltage capability suitable for industrial control environments

Applications

• Driving relays and solenoids in industrial control systems
• Actuating printer hammers in dot-matrix printing mechanisms
• Switching incandescent lamps and lighting loads
• General-purpose high-current switching in consumer electronics

Procurement Notes

Verify the specific suffix 'DG' corresponds to the SOIC-16 tube packaging format when sourcing. Confirm that the procurement specification aligns with the standard MC1413 electrical characteristics rather than the automotive-grade NCV1413B variant. Ensure the ordering documentation explicitly references the Pb-Free status associated with the 'G' suffix to match environmental compliance requirements.

Selection Notes

Select this component when a multi-channel driver is required for moderate current loads directly controlled by 5V logic. The integrated input resistors reduce bill-of-materials count compared to discrete solutions. Consider the thermal resistance of the SOIC-16 package if multiple channels operate simultaneously at high duty cycles. Verify that the 50 V rating meets the supply voltage requirements of the target application.

Part Context

This part belongs to the MC1413 family of high-voltage Darlington arrays produced by onsemi. The 'D' suffix identifies the surface-mount SOIC-16 package, while the 'G' suffix indicates lead-free manufacturing. It serves as a legacy alternative to modern integrated drivers but remains widely used due to its robustness and simple interface requirements.

Replacement Considerations

The MC1413DR2G is the tape-and-reel equivalent of the MC1413DG. The MC1413BDG offers a wider operating temperature range extending down to -40°C. Cross-reference with ULN2003A devices only if pinout compatibility and identical saturation voltage specifications are strictly required.
