MC1413BDG

Overview

The MC1413BDG 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. The device features an internal suppression diode to manage inductive load issues and includes a 2.7 kΩ series input resistor, making it compatible with 5.0 V TTL or CMOS logic systems. Key electrical specifications include a maximum collector-emitter voltage of 50 V, a continuous collector current of 500 mA, and a minimum DC current gain of 1000 at 350 mA. The operating ambient temperature range for the MC1413B variant extends from -40°C to +85°C.

Feature Summary

• Integrates seven NPN Darlington-connected transistors for high-gain switching applications.
• Includes internal suppression diodes to protect against voltage spikes from inductive loads.
• Features a 2.7 kΩ series input resistor designed for direct interfacing with 5.0 V logic families.

Applications

• Driving incandescent lamps in industrial and consumer equipment.
• Switching relays requiring high breakdown voltage and surge current handling.
• Actuating printer hammers in electromechanical systems.

Procurement Notes

Verify the specific suffix 'D' confirms the SOIC-16 surface-mount package configuration. Confirm the 'G' suffix indicates a lead-free compliant package as per onsemi standards. Ensure the procurement order matches the exact part number MC1413BDG to guarantee the correct thermal resistance and pinout associated with Case 751B. Cross-reference the ordering information table in the datasheet to confirm current availability status.

Selection Notes

Select this component when driving inductive loads such as relays or solenoids that require integrated flyback protection. The 2.7 kΩ input resistor simplifies driver circuit design for standard 5V logic interfaces. Consider the 50V output voltage rating for higher voltage switching tasks compared to lower-voltage alternatives. Evaluate the 500mA continuous current capability against the peak inrush requirements of the target load.

Part Context

The MC1413BDG belongs to the MC1413 family of high-voltage Darlington arrays. It shares functional similarities with the MC1413B but is distinguished by its specific SOIC-16 packaging (Case 751B). This family is designed to replace discrete transistor solutions, reducing board space and assembly complexity while providing robust drive capabilities for heavy loads.

Replacement Considerations

Public confirmed substitute part numbers include MC1413DR2G and MC1413DG. Verify pin compatibility and thermal characteristics when substituting between tube and tape-and-reel variants within the same package type.
