Vishay DC Input Optocoupler Surface Mount Mini-Flat 4-Pin TCMT1107

Vishay TCMT1107 is a DC input optocoupler featuring a phototransistor output in a surface-mount 4-pin Mini-Flat package. It provides electrical isolation between input and output through optical coupling, critical for protecting sensitive circuits.

The optocoupler has a maximum forward voltage of 1.6 V and allows up to 60 mA of input current. Its wide operating temperature range from -40°C to 100°C makes it suitable for industrial and commercial electronics exposed to environmental stress.

Its low profile and mini-flat packaging enable high-density PCBs in compact electronics. The device exhibits a low coupling capacitance (~0.3 pF) minimizing signal distortion during switching.

The TCMT1107 is rated for an isolation voltage of 3750 VRMS ensuring robust galvanic isolation. The current transfer ratio is tightly grouped with a minimum of 80% and a maximum of 160%, providing reliable signal fidelity.

Typical rise and fall times of 3 μs and 4.7 μs facilitate fast switching applications. The optocoupler complies with international safety standards UL1577, CSA 22.2 Bulletin 5A, VDE 0884-5, EN60950-1, and others, certifying its suitability for global markets.

Common application areas include programmable logic controllers, modems, answering machines, and general use where electrical isolation and signal transmission are required. The TCMT series represents a trusted choice for precise, reliable optoelectronic performance.
