Built on Vishay Telefunken co-planar technology, the four-lead Miniflat optocouplers ensure maximum safety and reliability by providing a stable distance between the emitter and detector chips. Providing an insulation voltage of 3750 Vrms, the surface mountable devices also feature a transistor output and a forward current of 60 mA. Vishay offers eight different CTR options in the TCMT11xx family, with values ranging from 80% to 600%. Additional series features include a wide operating ambient temperature range spanning from 40 ° C to 100 ° C, a low typical coupling capacitane of 0.3 pF, and a low temperature coefficient of current transfer ratio. All eight of the TCMT11xx devices are supplied in reel and tape packaging for high-speed assembly, with 3000 pieces per reel.
