Designed for high-current switching and amplifier circuits, including switching regulators, converters, inverters, and power oscillators.\u003cbr\u003e\u003cbr\u003eRatings include 20A continuous collector current, 75V collector-emitter sustaining voltage, and 140W power dissipation at a 25°C case temperature. Operation must remain within the manufacturer’s safe operating area and thermal limits.\u003cbr\u003e\u003cbr\u003eThe photographed component is marked 2N5039, RCA, HNC, and 8441. Includes one transistor. Please review the photos for physical condition and markings.\u003cbr\u003e\u003cbr\u003eCompatibility:\u003cbr\u003eDirect replacement for the 2N5039 in switching regulators, inverters, wide-band amplifiers and power oscillators. The 2N5038 is the higher-voltage (90V) version of the same 20A, 140W TO-3 transistor.\u003cbr\u003e\u003cbr\u003eQ\u0026amp;A\u003cbr\u003eQ: What is the difference between the 2N5038 and the 2N5039?\u003cbr\u003eA: Both are 20A, 140W NPN power transistors in TO-3. The 2N5038 is rated 90V VCEO(sus) with hFE 20–100 at 12A; the 2N5039 is rated 75V with hFE 20–100 at 10A.\u003cbr\u003eQ: Which terminal is the collector?\u003cbr\u003eA: On a TO-3 package, the metal case is the collector. The two pins are the base and the emitter.\u003cbr\u003eQ: Is a mounting kit included?\u003cbr\u003eA: No. The listing is for the transistor only.\u003cbr\u003e\u003cbr\u003eDISCLAIMER\u003cbr\u003ePlease review all photos and item specifics carefully before purchase. Confirm the exact part number, pin configuration, and application requirements before installation.\u003cbr\u003e\u003cbr\u003eLEGAL DISCLAIMER\u003cbr\u003eAmerican Industrial Parts Group is not an authorized distributor, reseller, or representative of RCA.
