TT Electronics - Optek Technology OP805SL NPN Silicon Phototransistor

The OP805SL is an NPN silicon phototransistor equipped with high power dissipation capabilities and designed for operation in harsh environments. Its narrow receiving angle ensures excellent on-axis coupling, and the base lead is bonded for conventional transistor biasing. The device is spectrally and mechanically matched to the OP130 and OP230 series of integrated LED emitters. It is available in various sensitivity ranges and offers an enhanced temperature range, making it suitable for industrial applications. Due to high market demand, lead times may be extended, and delivery dates are subject to fluctuation. This product is exempt from discounts.
