... Technology, with vertical current flow power darlington and logic level compatible driving circuit. The VB125SP can be directly biased by using the 12V battery voltage, thus avoiding to use a low voltage regulator. It has built-in protection circuits for coil current limiting and collector voltage clamping suitable as smart, high voltage, high current interface in advanced electronic ignition system ...
