| Parameter | ||
|---|---|---|
| Supply voltage | - | VCEO -250V; VCBO -400V; RthJC 0.7 degC/W. |
| Memory & Peripherals | - | Matched with MJL21194; onsemi characterizes the pair for audio output stages. |
| Case | TO-3P(L) | TO-3PL / TO-264 |
| Compatibility Level | - | Functional Equivalent |
| Component Category | Audio Power Transistors (Complementary Pair) | - |
| Core & Architecture | - | The PNP member: -250V, -16A, 200W, fT 4MHz class - replaces the 2SA1943 position where more dissipation headroom is wanted. |
| Firmware Notes | - | Same discipline as the NPN side: substitution is about the amplifier thermal design, not the socket - re-verify bias and stability after fitting. |
| Hardware Notes | - | TO-3PL / TO-264 outline; check the mechanical fit (drilling, insulator) as with the NPN companion. |
| 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 onsemi production; pairs sourced from one lot on request. |
| Sourcing Status | Active Shenzhen Spot Sourcing (24–48h) | - |
