2SC5476

Single Bipolar Transistors Overview

The onsemi 2SC5476 is an NPN silicon planar Darlington transistor designed for high-current switching applications. It features a collector-emitter voltage rating of 85V and a continuous collector current capacity of 3A. The device incorporates an integrated Zener diode between the collector and base terminals, rated at 95±10V, to protect against inductive load voltage spikes. Key electrical characteristics include a high DC current gain and wide safe operating area (ASO), enabling robust handling of inductive loads such as motors and relays.

Single Bipolar Transistors Feature Summary

• Integrated Zener diode between collector and base for inductive spike protection
• High DC current gain suitable for driver circuits
• Wide Safe Operating Area (ASO) for reliable switching
• Large current capacity with uniform collector-to-base voltage characteristics

Single Bipolar Transistors Applications

• Printer hammer drivers
• Relay drivers
• Inductive load switching

Single Bipolar Transistors Procurement Notes

Verify the manufacturer origin carefully, as the 2SC5476 part number was originally established by Sanyo Semicon Device. While listed under onsemi due to corporate acquisitions, confirm that the specific procurement lot matches the desired datasheet revision and pinout configuration. Ensure the component meets the required RoHS compliance status for your target market before finalizing orders.

Single Bipolar Transistors Selection Notes

Select this component when designing circuits requiring high current switching with built-in overvoltage protection for inductive loads. The integrated Zener diode simplifies design by eliminating external protection components. Consider the package thermal dissipation capabilities and ensure the driving circuit can provide sufficient base current to achieve the specified saturation levels for efficient operation.

Single Bipolar Transistors Part Context

This device belongs to the family of power Darlington transistors used in industrial and consumer electronics. It serves as a bridge between low-power control logic and high-power loads. The inclusion of the internal Zener diode distinguishes it from standard Darlington pairs, offering enhanced reliability in environments prone to back-EMF generation from solenoids or motor windings.

Single Bipolar Transistors Replacement Considerations

Check for direct equivalents from other manufacturers holding the same 2SC prefix designation. Verify pin compatibility and electrical ratings against original Sanyo specifications if substituting with non-onsemi sources. Ensure any replacement maintains the integrated Zener diode functionality if inductive load protection is critical.
