MC1413D

MC1413D Description

The MC1413D from onsemi is a high-performance 7-channel NPN Darlington transistor array designed for demanding switching and amplification applications. Housed in a 16-pin SOIC package, it integrates seven Darlington pairs with common emitters, offering a collector-emitter breakdown voltage (VCEO) of 50V and a maximum collector current (Ic) of 500mA per channel. With a minimum DC current gain (hFE) of 1000 at 350mA and 2V, this device ensures high current drive capability while maintaining low saturation voltage (1.6V max at 500µA base current and 350mA collector current). Its surface-mount design and MSL 1 (unlimited) moisture sensitivity make it suitable for automated assembly processes.

MC1413D Features

• 7 NPN Darlington Transistors: Integrated array for compact, multi-channel designs.
• High Current Gain (hFE ≥ 1000): Ensures efficient signal amplification with minimal base current.
• Low Saturation Voltage (1.6V max): Reduces power dissipation in switching applications.
• Wide Operating Temperature (Up to 150°C TJ): Reliable performance in harsh environments.
• 50V Collector-Emitter Voltage Rating: Suitable for medium-voltage applications.
• Surface-Mount (SOIC-16) Package: Optimized for space-constrained PCB layouts.
• Obsolete Status: May require alternative sourcing for new designs but remains viable for legacy systems.

MC1413D Applications

The MC1413D is ideal for applications requiring high-current switching or amplification across multiple channels, such as:

• Relay and Solenoid Drivers: Efficiently controls inductive loads with minimal power loss.
• LED Display Drivers: Drives multiple LED segments or arrays with high brightness.
• Industrial Automation: Interfaces between low-power logic (e.g., microcontrollers) and high-power actuators.
• Automotive Systems: Used in lighting, motor control, and sensor interfaces (within temperature limits).
• Telecom and Networking Equipment: Signal buffering and line driving in communication modules.

Conclusion of MC1413D

The MC1413D stands out for its high integration, robust Darlington pairs, and reliable performance in multi-channel drive applications. While marked as obsolete, its low saturation voltage, high current gain, and 50V rating make it a preferred choice for legacy designs requiring dependable switching or amplification. Engineers should evaluate alternative modern equivalents for new projects but can leverage the MC1413D’s proven performance in existing systems.
