MC1413PG

Overview

The MC1413PG is a high-voltage, high-current NPN Darlington transistor array manufactured by onsemi. It integrates seven independent Darlington-connected transistors within a single package, designed for driving inductive loads such as relays and printer hammers. The device features internal suppression diodes to protect against voltage spikes from inductive kickback. It operates with a maximum collector-emitter voltage of 50 V and supports continuous collector currents up to 500 mA per channel. The input stage includes series resistors compatible with 5.0 V TTL or CMOS logic levels. This specific variant utilizes a 16-pin Plastic Dual In-Line Package (PDIP) with a lead-free construction.

Feature Summary

• Integrates seven NPN Darlington pairs for high-gain switching applications
• Includes internal clamp diodes across each output to suppress inductive load voltage spikes
• Features built-in series input resistors suitable for direct interfacing with 5V logic families
• Supports peak inrush currents sufficient for driving incandescent lamps

Applications

• Driving electromagnetic relays in industrial control systems
• Actuating printer hammers and solenoids
• Switching incandescent lamps and lighting circuits
• General-purpose high-voltage switching in consumer electronics

Procurement Notes

Verify the component marking aligns with the PDIP-16 package designation. Confirm the suffix 'G' indicates lead-free compliance if required by assembly specifications. Ensure the operating temperature range matches the specific sub-model variant, as ratings differ between standard and automotive grades. Validate pinout compatibility with existing PCB footprints before integration.

Selection Notes

Select this component when high voltage isolation and current gain are required for low-power logic control. The integrated input resistors simplify driver circuit design by eliminating external base resistors. Consider thermal dissipation requirements for the PDIP package when multiple channels are active simultaneously. Verify that the 50V breakdown voltage meets the load requirements.
