Rated for continuous operation from -55 °C to +110 °C, it suits industrial control and power-supply feedback loops where the ambient temperature stays well above commercial-grade limits. ## CTR and output drive — what the numbers mean for your BOM The output transistor can sink up to 50 mA continuous and block up to 32 V, so it drives a standard 5 V or 24 V logic input directly through a collector resistor without a buffer stage. Switching is not fast — typical turn-on is 11 µs and turn-off is 7 µs, with rise and fall times of 7 µs and 6.7 µs respectively — so this part is intended for DC-level signalling and low-frequency status feedback, not high-speed data links. ## Package, compliance, and sourcing Housed in a 6-DIP (0.300-inch, 7.62 mm pitch) through-hole package, supplied in tubes — the standard footprint for socketed or soldered board-level isolation. Vishay lists the TCDT1103 as Active and RoHS3 compliant.","metaTitle":"Vishay TCDT1103 Optoisolator, 5kVrms, Transistor Output","metaDescription":"Vishay TCDT1103 optocoupler: 5000Vrms isolation, 100-200% CTR at 10mA, 50mA output, -55 to +110°C.
