    RCA - 2N3055HOM / 2N3055H Transistor, NPN Silicon.

    Over time, RCA changed the structure of the 2N3055 transistors. The first transistors were called hometaxial, and this model is certainly one of them. They were manufactured by simultaneously inversely doping a wafer with a base doping on both sides, thus generating the emitter and collector layers. Then only the base layer had to be etched free for contacting. 

    Max Voltage: 60V.

    Max Current: 15 Amp collector, 7 Amp base.

    Dissipation: 115 Watt.

    Package: TO-3 Steel.

    Application: Designed for general purpose switching and amplifier applications.

    Operating Temperature: -65 to +200 DegC.

    RCA - 2N3055HOM is a High Reliability Version "Hometaxial Selected version" of the old standard which often works as compared to earlier versions "E" (Epitaxial).

    Genuine Vintage RCA - New Old Stock - Rare

    Alternates: ECG130, BDY73

    Note: Genuine RCA 2N3055HOM/2N3055H Power Transistors have a reduced bandwidth as compared to the new currently manufactured 2N3055 replacements. Repair shop personnel report 2N3055H transistors perform better in vintage equipment. Few suppliers still have the older RCA 2N3055H transistors.
