Frequently Asked Questions
What isolation voltage and current transfer ratio does the TCET1103 provide?
The Vishay TCET1103 offers an isolation voltage of 5000 V and a nominal current transfer ratio (CTR) of 70%. The collector-emitter breakdown voltage is 70 V minimum, and maximum forward current is 60 mA, making it suitable for safely isolating low-voltage control circuits from high-voltage power rails in industrial designs.
How does the DIP-4 package of TCET1103 simplify PCB integration compared to SMD optocouplers?
The TCET1103's through-hole DIP-4 package offers 4 pins in a standard 2.54 mm footprint, enabling straightforward hand-soldering and easy replacement during prototyping. Unlike SMD alternatives, the DIP-4 package provides better mechanical retention and is preferred in industrial and control panels where long service life and field serviceability with 5000 V isolation are required.
Which industrial safety certifications does the TCET1103 carry, and what designs does that enable?
The TCET1103 carries UL and VDE approvals, reflecting its compliance with industry safety standards for reinforced isolation at 5000 V. These certifications qualify it for use in medical-grade power supplies, home appliances, and industrial motor controllers where regulatory compliance is mandatory, supporting forward currents up to 60 mA across single-channel isolation barriers.
