The BUX48A Transistor with NPN/PNP is a TO-3 package manufactured by SPTECH. It is forward biased, with an average on-resistance of 0.1 ohms, a voltage rating between a range of 12 to 100 volts and a current rating of 15 to 200 amps. The transistor is RoHS compliant, meaning it is free from any hazardous materials such as lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (CrVI), polybrominated biphenyls (PBBs), and polybrominated diphenyl ethers (PBDEs). It is designed for applications requiring high operating cost efficiency, such as in customer power solutions, medical equipment, LED lighting, power supplies, and power control circuits. It offers an improved performance in low voltage operation, improved immunity against transient thermal conditions, and an improved cost effectiveness.
