Product Details

2SC828 NPN Transistor - Classic AF Amplifier & Switching BJT

The 2SC828 is an NPN silicon epitaxial planar transistor originally developed for audio frequency amplification and low-power switching stages. It remains a popular choice among hobbyists restoring vintage audio gear or building small-signal amplifier and oscillator circuits, thanks to its widely available direct and SMD equivalents.

Functions & Applications

Silicon Epitaxial Planar Construction: Provides stable gain and low noise for audio-frequency amplification stages.
Compact TO-92 Package: Through-hole format, easy to solder onto breadboards and prototype PCBs.
High Current Gain (hFE): Depending on the Q/R/S grade, hFE ranges from 130 up to 520, suitable for sensitive preamp and driver stages.
Proven Switching Performance: Handles up to 100mA peak collector current, ideal for driving small relays, LEDs and logic-level loads.
Wide Cross-Reference Support: Multiple modern equivalents (e.g. 2SC1815, 2N3904, BC548) make sourcing replacements straightforward.

Frequently Asked Questions

Q: What is the complementary PNP transistor for the 2SC828?
A: The complementary PNP counterpart is the 2SA564, which shares similar voltage and current ratings for push-pull or complementary designs.

Q: Can the 2SC828 be replaced with a more common part?
A: Yes, common substitutes include the 2SC1815, 2N3904, BC548 and BC550, though you should check the hFE grade and pinout before swapping.

Notes

This is a legacy/vintage part number, commonly found in older Japanese audio equipment and hobby stock; pinout may vary by manufacturer batch, so verify before use.
