TLP3052(D4LF2S,C,F) – Phototriac Output Optocoupler – Toshiba

The Toshiba TLP3052(D4LF2S,C,F) is a single-channel, non-zero-cross (random-phase) phototriac output optocoupler in a 6-lead DIP package, rated for 600V peak off-state voltage and 5000Vrms isolation. Now obsolete and available by RFQ.

The Toshiba TLP3052(D4LF2S,C,F) is a phototriac output optocoupler (optoisolator) consisting of a photo-triac optically coupled to a gallium arsenide infrared emitting diode, housed in a six-lead plastic DIP package. It is a non-zero-cross (random-phase) device designed to drive higher-power triacs and to serve as an isolated AC switching element in solid-state relay and equipment-control applications. The “(D4LF2S,C,F)” suffix designates the specific lead-form, packing, and shipping configuration of the base TLP3052 device.
