You cannot safely build a verified inverter from the 2SC5200 transistor’s specifications alone. Toshiba identifies the 2SC5200 as an NPN power transistor for audio-amplifier output stages—not as a validated inverter design. Its maximum ratings do not tell you an inverter’s output voltage, waveform, power, or safe operating limits.
What is the 2SC5200 transistor for?
Toshiba describes the 2SC5200 as an NPN power transistor intended for an “Audio amplifier output stage 100-W” application. That description concerns its role in an amplifier design; it does not mean one transistor alone delivers 100 W, and it does not establish inverter suitability. Toshiba lists the PNP 2SA1943 as its complementary product. A complementary transistor pair is not, by itself, a complete amplifier or inverter circuit. Toshiba’s 2SC5200 product information and datasheet provide the component-level details.

Why the published ratings do not tell you inverter power
Toshiba lists absolute maximum ratings of 15 A collector current, 150 W collector power dissipation, and 230 V collector-emitter voltage for the 2SC5200. These are device limits, not recommended operating targets or finished-circuit output ratings. They must not be treated as simultaneously usable values or converted into an inverter wattage, efficiency estimate, or safe continuous-load claim.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
An inverter needs a complete design matched to its input supply, desired AC output and waveform, load, switching and drive requirements, protection, and thermal conditions. The transistor’s maximum ratings do not provide those circuit specifications or show that a particular circuit works.

Does a 2SC5200 inverter circuit exist?
The available manufacturer information does not validate a 2SC5200 inverter topology or specify its input voltage, output voltage, waveform, power, transformer, driver, protection, or test results. A video result that names the 2SC5200 describes an audio-amplifier project using a 12 V DC source and a heatsink; that is not evidence for an inverter circuit. Without a complete design validated for the intended input, output, and load, there are no responsible construction steps to give.
What should you do instead?
- If you want DC-to-AC conversion: use a complete inverter design or product with specifications for your input source, required AC output, waveform, load, protection, and thermal design. Do not derive a build from the 2SC5200’s absolute maximum ratings.
- If you meant an audio amplifier: correct the project description and work from a complete amplifier schematic whose supply rails, output load, device count, protection, and thermal design are specified. Toshiba’s application description is not a complete schematic.
- If sourcing the transistor: check the exact part number, package, seller provenance, and current availability. Toshiba marks both the 2SC5200 and 2SC5200N “Not Recommended for New Design,” so their status and supply should be confirmed before purchase.
Thermal design and safe operating limits
A power transistor’s heat handling depends on the actual circuit and operating conditions. Toshiba links guidance on bipolar-transistor thermal stability and thermal design, but the component page does not establish a heatsink size for a proposed build. Heatsink selection requires design-specific thermal analysis; a generic heatsink recommendation or the 150 W maximum dissipation figure is not a substitute.

For the same reason, do not infer a safe current or output power from a single headline rating. A finished design must keep every component within its applicable limits under its actual load and cooling conditions.
