The -55°C to 100°C operating range covers industrial enclosures and outdoor telecom cabinets, with the 400mV max Vce saturation keeping power dissipation low across temperature. Supplied in tape and reel or cut tape options, it is ready for high-volume pick-and-place assembly on standard 8-SMD gull wing footprints.","metaTitle":"onsemi MCT623SD Optoisolator, 5kV Isolation, 2-Ch, 8-SMD","metaDescription":"onsemi MCT623SD dual-channel transistor output optocoupler with 5000Vrms isolation, 100% CTR at 5mA, -55°C to 100°C.
