The 2SC1124 (C1124) is a high-performance NPN BJT designed for high-fidelity audio, featuring 160V VCBOcap V sub cap C cap B cap O end-sub
and 1A collector current in a TO-202/TO-220 package. Commonly paired with the 2SA706 for Class AB amplifiers, this transistor offers high linearity and thermal stability, with common alternatives including 2SC1162 and 2SC5200. Detailed specifications and application data are available from UXPython and AllTransistors.
The 2SC1124 is a vintage, high-voltage NPN silicon BJT designed for audio amplification, featuring 140V-160V VCEOcap V sub cap C cap E cap O end-sub c1124 transistor datasheet better
and 1A collector current in a TO-202/TO-220 package. Commonly used in 1980s consumer electronics, this transistor is frequently paired with the 2SA706 for push-pull applications. Detailed specifications are available in the 2SC1124 datasheet from LittleDiode.
If your device has a blown C1124, don't just swap it. Something killed it: TIP41C:
When you are repairing vintage electronics, audio amplifiers, or switching power supplies, you will eventually come across the C1124 transistor. This Japanese NPN epitaxial silicon transistor (often marked as 2SC1124) was a workhorse of the 1980s and 1990s. However, if you are reading this article, you have likely run into a common problem: The original datasheet is hard to read, the part is obsolete, or you need a better performing component.
Searching for a "c1124 transistor datasheet better" is a smart move. You aren't just looking for a scan of an old document; you want a modern equivalent that outperforms the original. The 2SC1124 (C1124) is a high-performance NPN BJT
In this guide, we will break down the original C1124 specifications, explain why you need a "better" version, and provide a curated list of superior, readily available replacement transistors.
If you simply need a working replacement without the headache, search for NTE375 or NTE192. NTE provides a modern datasheet for the replacement part that includes all the original specs plus modern safety margins. Their datasheet is infinitely better than the original C1124 sheet.
Type: NPN silicon transistor
Package: TO-92 (plastic)
