C1124 Transistor Datasheet Better Link Jun 2026

The C1124 had poor thermal transfer. A "better" transistor will have a lower RθJA, meaning it stays cooler for the same power dissipation.

: Always ensure a proper heat sink is used if the transistor is operating near its c1124 transistor datasheet better

For the (flat face, leads down, left to right): The C1124 had poor thermal transfer

Based on the part number "C1124," you are most likely looking for the transistor, or potentially the 2SC1123/1124 series used in older audio equipment. c1124 transistor datasheet better

: Viewed from the front (flat side with markings): Emitter

The original C1124 has a narrow DC SOA. A better replacement will have a flatter, wider SOA. Look for a transistor that can handle 60V at 1A DC without thermal runaway.
