TCMT1103 Description

Short technical summary and product information.

The Vishay TCMT1103 is a single-channel optocoupler designed for applications requiring electrical isolation. It consists of an infrared-emitting diode coupled to a phototransistor.

 

Key electrical specifications include an AC isolation test voltage of 3750V RMS, a typical forward current of 60 mA, and a maximum collector current of 50 mA. The current transfer ratio (CTR) ranges from a minimum of 100% at 10mA to a maximum of 200% at 10mA. The Vce saturation voltage is a maximum of 300mV. Typical turn-on time is 9.5µs and turn-off time is 5.5µs.

 

This optocoupler operates within a temperature range of -40°C to 100°C. It is packaged in a compact 4-SOP surface-mount package, making it suitable for space-constrained designs. The input type is DC.

 

Applications for the TCMT1103 include programmable logic controllers, modems, and answering machines, where reliable signal isolation is critical.
