MC1413BPG

Overview

The MC1413BPG is a high-voltage, high-current Darlington transistor array manufactured by onsemi. It integrates seven NPN Darlington-connected transistors within a single package, designed to drive inductive loads such as relays, lamps, and printer hammers. The device features internal suppression diodes to protect against voltage spikes from inductive kickback. Each channel includes a 2.7 kΩ series input resistor, allowing direct interfacing with 5.0 V TTL or CMOS logic circuits without additional buffering components.

Feature Summary

• Integrates seven independent NPN Darlington pairs for simultaneous multi-channel load driving
• Includes built-in clamp diodes across each output to suppress inductive voltage transients
• Features integrated 2.7 kΩ base resistors for direct compatibility with standard logic families
• Provides high collector-emitter breakdown voltage suitable for industrial switching applications

Applications

• Driving electromagnetic relays and solenoids in industrial control systems
• Powering incandescent lamps and indicator lights in consumer electronics
• Actuating printer hammers and mechanical actuators in office equipment
• Interface circuits between microcontrollers and high-power peripheral devices

Procurement Notes

Verify the specific suffix 'P' indicates the PDIP-16 through-hole package configuration when sourcing replacements. Confirm that the 'G' suffix denotes lead-free compliance if environmental regulations apply to the assembly process. Ensure the operating temperature range requirements align with the MC1413B specification of -40°C to +85°C rather than the standard MC1413 rating.

Selection Notes

Select this component when multiple low-current logic outputs must switch higher voltage or current loads simultaneously. The internal 2.7 kΩ resistors simplify circuit design by eliminating external base resistors. Consider the thermal resistance characteristics and duty cycle limitations if driving continuous high-current loads like incandescent lamps to prevent junction overheating.

Part Context

This part belongs to the MC1413 family of high-voltage Darlington arrays produced by onsemi. The MC1413B variant offers an extended operating temperature range compared to the standard MC1413. The PG suffix specifically identifies the plastic dual in-line package (PDIP) version, distinguishing it from surface-mount SOIC alternatives like the MC1413BDG.

Replacement Considerations

Compatible substitutes include the ULN2003A and ULQ2003A arrays, which offer similar Darlington configurations. Verify pinout compatibility and saturation voltage specifications before swapping, as interface requirements may differ slightly between manufacturers.
