| Market Reality | The S8050 / S8550 pair is the transistor of Chinese mass production - relays, chargers, LED drivers, small audio stages, appliance boards. Every fab makes it, it costs almost nothing, and that is exactly the problem: vendor specifications drift (collector-emitter ratings quoted at 20V by some makers and 25V by others), the SS prefix versions pass over twice the current in the same body, and the TO-92 lead order (E-B-C) is the mirror of the European small-signal parts it gets cross-referenced against (C-B-E). Substitution on this pair is a pinout and vendor-grade exercise, not an electrical one. | - |
