OP555A

The OP555A belongs to OP555 series devices which consist of NPN silicon phototransistors molded in blue tinted epoxy packages. The tensing effect of the package allows an acceptance half angle of 28° measured from the optical axis to the half power point. These devices are 100% production tested using infrared light for close correlation with Optek's GaAs and GaAIAs emitters. The wide receiving angle provides relatively even reception over a large area. The sidelooking package is designed for easy PC board mounting of slotted optical switches or optical interrupt detectors.

The features of OP555A can be summarized as (1)wide receiving angle; (2)variety of sensitivity ranges; (3)side-looking package for space limited applications.

The absolute maximum ratings of OP555A are (1)collector-emitter voltage: 30 V; (2)emitter-collector voltage: 5.0V; (3)storage and operating temperature range: -40°C to +100°C; (4)lead soldering temperature [1/16 inch iron]: 260°C(1 RMA flux is recommended. Duration can be extended to 10 sec. max. when flow soldering. Max. 20 grams force may be applied to leads when soldering.); (5)power dissipation: 100mW(2 derate linearly 1.33mW/°C above 25°C).
