2SC1815 PBFREE

Single Bipolar Transistors Overview

The Central Semiconductor Corp 2SC1815 PBFREE is a silicon NPN transistor manufactured via the epitaxial planar process. It features a maximum collector-base voltage of 60 V, a collector-emitter voltage of 50 V, and an emitter-base voltage of 5.0 V. The device supports a continuous collector current of 150 mA with a power dissipation rating of 400 mW. Electrical characteristics include a transition frequency (fT) of 80 MHz at 1.0 mA. DC current gain (hFE) ranges from 70 to 700 depending on the specific sub-model variant.

Single Bipolar Transistors Feature Summary

• Designed for general-purpose amplifier applications using an epitaxial planar process
• Offers multiple gain variants defined by suffix codes ranging from low to high hFE
• Utilizes a standard TO-92 through-hole package configuration

Single Bipolar Transistors Applications

• Switching applications requiring small-signal control
• Audio pre-amplifier stages

Single Bipolar Transistors Procurement Notes

Verify the exact ordering suffix required for the desired gain range, as the base part number covers multiple performance tiers. Confirm RoHS compliance status and plating options directly with the manufacturer or authorized distributors prior to finalizing orders. Ensure that the selected variant meets the specific hFE requirements of the target circuit design.

Single Bipolar Transistors Selection Notes

Select the appropriate suffix based on the required DC current gain (hFE) for the application. The standard 2SC1815 offers a broad gain range, while -O, -Y, -GR, and -BL variants provide tighter or higher gain specifications. Consider the thermal resistance and power dissipation limits when designing heat management strategies for the TO-92 package.
