TCMT11.. Series/TCMT4100 is a product of Vishay Semiconductors. It is a photocoupler with low profile package, low coupling capacitance and low temperature coefficient.
The TCMT11.. Series optocouplers from Vishay combine a gallium arsenide infrared LED with a phototransistor in a low‑profile, half‑pitch package. They are intended for use in programmable logic controllers, modems, answering machines, and general industrial applications where isolation and low coupling capacitance are required.
Key specifications include an AC isolation test voltage of 3750 V RMS, CTR ranges from 50 % to 600 %, low coupling capacitance (typical 0.3 pF), and operating temperature from –40 °C to +100 °C. Package options cover 4‑pin single‑channel and 16‑pin quad‑channel configurations with detailed mechanical dimensions provided.
