| Parameter | ||
|---|---|---|
| Supply voltage | - | VCEO 250V; VCBO 400V; IC 16A (30A peak); RthJC 0.7 degC/W; hFE 25-75 at 8A. |
| Memory & Peripherals | - | Complementary PNP is the MJL21193. Total harmonic distortion characterized by onsemi for audio duty. |
| Case | TO-3P(L) | TO-3PL / TO-264 |
| Compatibility Level | - | Functional Equivalent |
| Component Category | Audio Power Transistors (Complementary Pair) | - |
| Core & Architecture | - | NPN rated 250V, 16A, 200W with a much lower transition frequency: fT 4MHz minimum versus roughly 30MHz for the original - excellent for output stages at high bias, different in fast designs. |
| Firmware Notes | - | Much higher current gain linearity and dissipation, much slower switching. In audio output stages the lower fT is usually inaudible; in designs with high loop bandwidth, re-check stability margins and the Zobel network. |
| Hardware Notes | - | TO-3PL / TO-264 outline is larger than TO-3P(L) - verify heatsink drilling, insulator kit and body clearance before ordering this substitution in volume. |
| Lead Time Advantage | - | Shenzhen Spot Stock (24-48h Dispatch) |
| Market Reality | The 2SC5200 (NPN) and 2SA1943 (PNP) pair is the default output stage of generations of audio amplifiers, and it is one of the most counterfeited transistor families in the world - relabeled and re-died parts circulate heavily through marketplaces. Genuine Toshiba supply continues under the TTC5200 / TTA1943 part numbers with identical ratings, and the ON Semiconductor (onsemi) NJW0281G / NJW0302G and MJL21194 / MJL21193 pairs are the established second sources. For repair desks the hard problem is not finding a part - it is finding one that is not a relabel. | - |
| Reference Part | - | 2SC5200 / 2SA1943 |
| Role In Circuit | Original Reference Part | - |
| Sourcing Advantage | - | Active Western line, 200W class; the standard answer for amplifiers that have cooked the original pair. |
| Sourcing Status | Active Shenzhen Spot Sourcing (24–48h) | - |
