| Market Reality | - | The 13003 is less a part number than an industry specification: the standard high-voltage NPN for offline SMPS, CFL/LED ballasts and small chargers, made in TO-92, TO-126 and TO-220 by dozens of fabs under prefix variations (MJE / KSE / ST / 3DD). Two things decide whether a substitution works: the 700V figure everyone quotes is the collector-base rating while the sustaining collector-emitter rating is 400V, and self-oscillating ballast circuits depend on the switching speed and gain of the specific grade - not just its voltage. |
