MC1413BP

MC1413BP Description

The MC1413BP from onsemi is a high-performance 7-channel NPN Darlington transistor array housed in a 16-pin DIP (Dual In-line Package). Designed for through-hole mounting, this obsolete yet robust component offers a collector-emitter breakdown voltage of 50V and a maximum collector current of 500mA, making it suitable for medium-power switching and amplification tasks. Its Darlington configuration ensures high current gain (min hFE = 1000 @ 350mA, 2V) and low base drive requirements, ideal for interfacing low-power logic circuits with higher-current loads.

MC1413BP Features

• 7 NPN Darlington Pairs: Integrated array for multi-channel applications, reducing board space and complexity.
• High Current Gain: 1000 @ 350mA, 2V, enabling efficient signal amplification with minimal input current.
• Low Saturation Voltage: 1.6V @ 500µA, 350mA, minimizing power dissipation in switching applications.
• Wide Operating Temperature: Up to 150°C (TJ), ensuring reliability in harsh environments.
• Through-Hole Package (16DIP): Robust construction for easy prototyping and industrial use.
• Compliance: EAR99 (ECCN), REACH Unaffected, and MSL 1 (Unlimited) for broad usability.

MC1413BP Applications

The MC1413BP excels in applications requiring high-current switching or amplification with low control signal levels, such as:

• Industrial Control Systems: Driving relays, solenoids, and motors in automation equipment.
• LED Displays: Multiplexing and driving segments in large-scale displays.
• Logic Level Translation: Bridging 5V/3.3V logic to higher-voltage/current peripherals.
• Telecom Equipment: Signal buffering and interface circuitry.
• Obsolete Equipment Maintenance: Replacement for legacy systems due to its through-hole design.

Conclusion of MC1413BP

While obsolete, the MC1413BP remains a versatile and reliable Darlington transistor array for medium-power switching and amplification. Its high current gain, low saturation voltage, and multi-channel integration make it a preferred choice for industrial, display, and interface applications. Engineers maintaining legacy systems or seeking a cost-effective, through-hole solution for high-drive requirements will find this component exceptionally useful. For modern designs, alternative SMD options may be considered, but the MC1413BP stands out for its durability and ease of use in prototyping and repair scenarios.
