2SC2120-Y-AP

Single Bipolar Transistors Overview

The 2SC2120-Y-AP is an NPN silicon transistor manufactured by Micro Commercial Components in a TO-92 package. It serves as the complementary pair to the 2SA950 PNP transistor. The device features a collector-emitter voltage of 30 V, a collector-base voltage of 35 V, and an emitter-base voltage of 5.0 V. Maximum collector current is rated at 800 mA with a power dissipation of 600 mW. The junction temperature range extends up to 150 °C, and storage temperatures span from -55 °C to +150 °C. The 'Y' suffix indicates a DC current gain (hFE) rank of 160 to 320.

Single Bipolar Transistors Feature Summary

• Complementary pairing with the 2SA950 PNP transistor for matched performance
• Epoxy casing meets UL 94 V-0 flammability rating standards
• Moisture sensitivity level 1 classification for handling reliability
• Lead-free finish compliant with RoHS directives

Single Bipolar Transistors Applications

Single Bipolar Transistors Procurement Notes

Verify the ordering suffix matches the required specifications. The 'O' suffix denotes an hFE rank of 100-200, while the 'Y' suffix specifies a higher gain range of 160-320. Confirm packaging requirements, as 'BP' indicates bulk packing and 'AP' indicates ammo packing. Ensure procurement channels are authorized distributors to guarantee genuine parts and full traceability per manufacturer guidelines.

Single Bipolar Transistors Selection Notes

Select this component when a high-gain NPN transistor is needed to complement the 2SA950 PNP device. The 'Y' variant is appropriate for applications requiring an hFE between 160 and 320. Consider the TO-92 package constraints for thermal management, given the 600 mW dissipation limit. Verify that the 30 V collector-emitter voltage aligns with the circuit's maximum operating conditions.

Single Bipolar Transistors Part Context

This part belongs to the 2SC2120 series of NPN silicon transistors produced by Micro Commercial Components. It is specifically designed as a matched pair component to the 2SA950 PNP transistor, ensuring consistent electrical characteristics for push-pull or complementary amplifier configurations. The series utilizes standard TO-92 encapsulation suitable for through-hole mounting.

Single Bipolar Transistors Replacement Considerations

Direct functional substitutes include other NPN transistors with similar voltage and current ratings, such as the 2SC2120-O for lower gain requirements. Cross-reference datasheets for hFE ranges, saturation voltages, and transition frequencies to ensure compatibility in existing designs without modifying circuit parameters.

Single Bipolar Transistors FAQ

What is the difference between the 2SC2120-O and 2SC2120-Y variants?

The primary difference is the DC current gain (hFE) ranking. The 'O' suffix indicates an hFE range of 100 to 200, while the 'Y' suffix designates a higher gain range of 160 to 320.

Is the 2SC2120-Y-AP RoHS compliant?

Yes, the device features a lead-free finish and is RoHS compliant. The datasheet notes that the 'P' suffix typically designates RoHS compliance, but the entire 2SC2120 series is described as having a lead-free finish.

What does the 'AP' suffix indicate regarding packaging?

The 'AP' suffix indicates that the device is supplied in ammo packing, which contains 20,000 pieces per carton.
