If you need a for switching applications, choose the MJE340.
A high-quality datasheet isolates static (DC) and dynamic (AC) parameters to give circuit designers precise modeling inputs for SPICE simulations and structural worst-case analyses. DC Parameters Emitter Cutoff Current ( IEBOcap I sub cap E cap B cap O end-sub ): DC Current Gain ( hFEh sub cap F cap E end-sub ): Rank R: 60 to 120 Rank S: 100 to 200 Rank T: 160 to 320 (Measured at Collector-Emitter Saturation Voltage (
The (frequently abbreviated as C1124 ) is a legacy Silicon NPN Epitaxial Planar Bipolar Junction Transistor (BJT) originally developed by prominent Japanese manufacturers like Sony and Sanyo. Prized by audiophiles and repair technicians alike, understanding the core specifications of the C1124 transistor datasheet is essential for maintaining or retrofitting classic high-fidelity consumer electronics.
The KSC2690A has superior linearity. If you are repairing a vintage amplifier where the C1124 was used as a driver transistor, the KSC2690A will reduce distortion. It also comes in the modern TO-126L package.
: Commonly used as a driver transistor to supply clean current gain to large power output blocks (e.g., in vintage hardware like the Pioneer SX-828 Receiver).
