MC1413DR2G

Overview

The MC1413DR2G is a high-voltage, high-current NPN Darlington transistor array manufactured by onsemi. It integrates seven independent Darlington pairs within a single SOIC-16 surface-mount package. The device features an internal suppression diode connected to the common emitter pin (Pin 9) to manage inductive load flyback currents. Each channel includes a 2.7 kΩ series input resistor, facilitating direct interfacing with 5.0 V TTL or CMOS logic families. Key electrical ratings include a maximum collector-emitter voltage of 50 V and a continuous collector current of 500 mA per channel. The standard operating temperature range for this specific part number extends from -20°C to +85°C.

Feature Summary

• Integrates seven NPN Darlington-connected transistors with built-in 2.7 kΩ base resistors for simplified logic control.
• Includes a common cathode clamp diode at Pin 9 to suppress voltage spikes generated by inductive loads such as relays and solenoids.
• Designed for robust operation with peak inrush currents up to 500 mA, suitable for driving incandescent lamps and printer hammers.

Applications

• Driving relays and solenoids in industrial automation systems.
• Actuating printer hammers and mechanical actuators.
• Switching incandescent lamps and lighting circuits.
• General-purpose high-side switching for consumer electronics.

Procurement Notes

Verify the specific suffix against the manufacturer's current ordering information to confirm availability status. Some variants within the MC1413 family have been discontinued; ensure the exact part number matches active production lists. Confirm that the SOIC-16 package dimensions align with the target PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select the MC1413DR2G when a 50 V breakdown voltage and 500 mA output capability are required for inductive loads. The integrated 2.7 kΩ input resistors make this component appropriate for 5 V logic systems without additional external components. Consider thermal resistance values if multiple channels are driven simultaneously to ensure junction temperatures remain within safe operating limits.

Part Context

This component belongs to the MC1413 series of high-voltage Darlington arrays produced by onsemi. The 'D' suffix indicates the SOIC-16 surface-mount package, while 'R2G' denotes tape-and-reel packaging with lead-free construction. This series serves as a legacy alternative to modern ULN2003-type arrays, offering comparable functionality with specific voltage and current characteristics tailored for older industrial standards.

Replacement Considerations

Publicly confirmed substitute part numbers include MC1413DR2G (identical functional equivalent). Other similar devices such as ULN2003AIDR or ULN2003D1013TR share the SOIC-16 form factor but may differ in internal resistor values or clamping diode configurations. Verify pinout compatibility and electrical ratings before substitution.

FAQ

What is the function of Pin 9?

Pin 9 serves as the common connection point for the emitters of all seven Darlington pairs and acts as the cathode for the internal suppression diode used to protect against inductive kickback.

Can this device be driven directly by 5V logic?

Yes, the MC1413DR2G includes 2.7 kΩ series input resistors, making it well-suited for direct interfacing with 5.0 V TTL or CMOS logic outputs.

What is the maximum continuous collector current?

The maximum continuous collector current (Ic) for each channel is rated at 500 mA.
