Few suppliers still have the older RCA 2N3055H transistors. Repair shop personnel report 2N3055H transistors perform better in vintage equipment. Note: Genuine RCA 2N3055HOM/2N3055H Power Transistors have a reduced bandwidth as compared to the new currently manufactured 2N3055 replacements. RCA - 2N3055HOM is a High Reliability Version "Hometaxial Selected version" of the old standard which often works as compared to earlier versions "E" (Epitaxial). In this post we comprehensively discuss the pinout function, electrical specification, and application designs for the power transistor 2N3055. The 2N3055 is a power bipolar transistor designed to handle high power loads in the range of 100 V, and 15 amps. The circuit works but I’m not sure that is perfectly ok. 2N3055 Datasheet, Pinout, Application Circuits. In the picture you can see that I’m using a 2n2222 that controls a TIP3055 (or a 2N3055).

I need to control the speed of a dc motor (0.5 A no load, to 10 A full load). Max Current: 15 Amp collector, 7 Amp base.Īpplication: Designed for general purpose switching and amplifier applications. Control DC motor with transistor 2N3055, pwm from Arduino. Then only the base layer had to be etched free for contacting.

It is a transistor type of enduring popularity. Before you learn how to build this interesting and useful 100 watt amplifier circuit using 2N3055 transistors, a prior understanding of the involved circuit configuration would be very handy, let’s begin the explanation with the following points: Circuit Operation. Its numbering follows the JEDEC standard. It was introduced in the early 1960s by RCA using a hometaxial power transistor process, transitioned to an epitaxial base in the mid-1970s. They were manufactured by simultaneously inversely doping a wafer with a base doping on both sides, thus generating the emitter and collector layers. The 2N3055 is a silicon NPN power transistor intended for general purpose applications.
The first transistors were called hometaxial, and this model is certainly one of them. Over time, RCA changed the structure of the 2N3055 transistors.
