onsemi KSA643CYTA

The KSA643 is a PNP epitaxial silicon transistor designed for low frequency power amplifier applications, housed in a TO-92 package with dimensions of 4.58 mm in height and 2.29 mm lead span. It has a collector-base voltage rating of -40 V, collector-emitter voltage of -20 V, and continuous collector current of -500 mA, with a collector power dissipation of 500 mW. The device features a DC current gain (hFE) ranging from 40 to 400, depending on classification, and a collector-emitter saturation voltage of -0.3 V to -0.4 V at -500 mA collector current. The KSA643CYTA variant includes a center collector pinout (1. Emitter, 2. Collector, 3. Base) and is offered in tape and reel packing. It meets the AEC-Q200 qualification standard and is RoHS compliant.
