TCG85

Silicon NPN High-Voltage Power Transistor originally distributed by Toshiba under a specialized master service technician replacement brand catalog schema (TCG). This heavy-duty discrete power component is housed in a standard high-power TO-220 plastic package, engineered to handle a massive collector-emitter breakdown voltage ceiling up to 400 VDC and support continuous collector current streams up to 7A. It functions as a high-voltage electronic switch or linear regulator driver, forcefully modulating high-power current lines while safely resisting massive inductive kickback spikes and localized thermal stresses. It was universally deployed inside the switching power supply modules of CRT televisions, horizontal deflection output arrays, industrial motor actuators, and automated lighting regulators.
