Photo transistors KODENSHI ST-1MLA・ST-1MLB DIMENSIONS (Unit : mm) The ST-1MLA and 1MLB are high-sensitivity NPN silicon phototransistors mounted in TO-18 Type header with clear epoxy encapsulation. The phototransistors have a wide angular response and relatively low-cost compared to TO-18 can type devices. FEATURES •Wide angular response •Relatively low-cost against metal can package •Low profile package •Two leads (Collector, Emitter) ST-1MLA •Three leads (Collector, Emitter, Base) ST-1MLB APPLICATIONS •Optical counters •Infrared sensors •Camera stroboscopes ST-1MLA MAXIMUM RATINGS ST-1MLB (Ta=25℃) Item Symbol Rating Unit C-E voltage E-C voltage Collector current Collector power dissipation Operating temp.
