2SC1815-Y TIN/LEAD

Single Bipolar Transistors Overview

The Central Semiconductor Corp 2SC1815-Y TIN/LEAD is a small-signal NPN silicon epitaxial transistor housed in a TO-92 plastic package. It supports a maximum collector current of 150 mA and a collector-emitter breakdown voltage of 50 V. The device dissipates up to 400 mW of power with a transition frequency of 80 MHz. Operating temperatures range from -55 °C to +125 °C junction temperature.

Single Bipolar Transistors Feature Summary

• NPN silicon epitaxial construction for reliable signal amplification
• Designed specifically for RF and AF amplifier applications
• General-purpose utility suitable for broad electronic circuits

Single Bipolar Transistors Applications

• Radio frequency (RF) amplifier stages
• Audio frequency (AF) amplifier circuits
• General-purpose switching and amplification tasks

Single Bipolar Transistors Procurement Notes

Verify the specific suffix designation against manufacturer documentation to confirm lead finish composition, as variations exist between tin/lead and lead-free options. Confirm RoHS compliance status directly with the supplier or datasheet, as historical batches may differ. Ensure the TO-92 package dimensions match your PCB footprint requirements before finalizing procurement orders.

Single Bipolar Transistors Selection Notes

Select this component when a standard NPN small-signal transistor is required for low-power amplification. The 50 V rating and 150 mA current capacity suit general logic and analog interfaces. Consider the 80 MHz transition frequency for moderate-speed signal processing needs where higher frequencies are unnecessary.

Single Bipolar Transistors Part Context

This part belongs to the 2SC1815 family of NPN transistors widely used in consumer electronics. The Y variant typically denotes specific gain binning or manufacturing lot characteristics defined by the original Japanese standards. Central Semiconductor manufactures this legacy part to maintain compatibility with older designs requiring this specific form factor and electrical profile.

Single Bipolar Transistors Replacement Considerations

Consult official substitution guides for equivalent NPN transistors such as the 2SC1815-O or generic BC547 series if pinout compatibility allows. Verify that replacement devices meet the 50 V collector-emitter voltage and 150 mA current requirements to ensure circuit integrity without redesigning the surrounding components.
