   "description": "Manufacturer: TOSHIBA Manufacturer Part No: 2SA1943 Package / Case: TO-264 RoHS: Yes Datasheet: Click Here Specifications Current Rating: 15A Voltage Rated: 230V Transistor Type: PNP Features: Power Amplifier More Information Same Spec Items - SKU A-149 Manufacturer TOSHIBA MPN 2SA1943 Can be used with - Customer Ratings 5/5 Based on 1 reviews 5 Stars 3 4 Stars 0 3 Stars 0 2 Stars 0 1 Star 0 Write a review Price Quality Value Nov 9, 2013 These devices are originals I bought a few pairs of these transistors (C5200/A1943) from 100Electronics. They come with very original looking packages, the marking looks genuine. Both types came in the version \"-O\" which have more gain. I have run them through some tests: Hfe (beta, dc current gain) of these devices is in the manufacturers (Toshiba's) tolerances. Most of the devices had gain around 100 @Ic=5A, and the gain reduction with bigger collector current corresponds to the datasheet. Then I measured the Uceo voltage (base unconnected). The weakest from the batch had around 270V which is surprisingly good. The last test was the power current test. The transistor was connected to 5V supply, and loaded to 12 amps (60Watts) for one hour. It survived. I didn't measere ft or junction capacitances, nevertheless I can say, that 90%, these transistors are genuine. I wish 100Electronics retains their qualities. They've never sent me any broken or fake part. Jan",
