2SC4363-AC

Overview

The 2SC4363-AC is an active NPN pre-biased single bipolar transistor manufactured by onsemi. It features a collector-emitter breakdown voltage of 50 V and a maximum power dissipation of 200 mW. The device integrates a built-in bias resistor with a value of 4.7 kOhm, simplifying circuit design by reducing component count. Packaged in a 3-SSIP configuration, it serves as a compact solution for switching applications requiring integrated biasing.

Feature Summary

• Integrates a 4.7 kOhm bias resistor directly with the NPN transistor to simplify circuit layout
• Provides a 50 V collector-emitter breakdown voltage rating for signal switching
• Delivers 200 mW maximum power dissipation capability within a compact package

Applications

• General-purpose signal switching circuits
• Driver stages for low-power loads
• Logic interface buffering

Procurement Notes

Verify that the specific part number matches the required 3-SSIP package type and confirms the 4.7 kOhm internal bias resistance. Ensure the manufacturer designation aligns with onsemi specifications to guarantee correct electrical characteristics and pinout compatibility for the intended application design.

Selection Notes

Select this component when a discrete NPN transistor requires an integrated bias resistor to reduce board space and assembly complexity. The 50 V rating suits low-voltage logic interfaces, while the 200 mW dissipation limit defines its suitability for small-signal applications rather than high-power driving tasks.

Part Context

This component belongs to the family of single pre-biased bipolar transistors designed for efficient switching operations. Unlike standard discrete transistors, it combines the active device and necessary biasing network into a single unit, offering a streamlined alternative for designs prioritizing minimal footprint and simplified schematic architecture.

Replacement Considerations

Substitutes must maintain the NPN polarity, 3-SSIP package form factor, and approximately 4.7 kOhm internal bias resistance. Verify that replacement parts meet or exceed the 50 V breakdown voltage and 200 mW power dissipation requirements to ensure functional equivalence.
