High-Voltage NPN Power Transistor with Integrated Damper Diode, specifically engineered to handle horizontal deflection sweep driving inside color television and CRT monitor chassis. It manages an extreme collector-emitter pulse voltage threshold up to 1500V paired with built-in back-EMF suppression to prevent structural junction breakdown, housed in a standard through-hole TO-3P or isolated power package. Manufactured by Matsushita / Philips.
