TCLT1007 VISHAY Isolators

The TCLT1007 from Vishay is a single-channel phototransistor optocoupler offering 5000Vrms isolation in a surface-mount SOP-4L mini-flat package. For selection, key parameters include its DC transistor output with 50mA collector current and 70V maximum output voltage, making it suitable for logic-level signal isolation. The current transfer ratio (CTR) ranges from 80% to 160% at 5mA, with a typical forward voltage of just 1.25V for easy LED drive. Fast switching times (6µs turn-on, 5µs turn-off) support moderate-speed digital signals, while the extra-low coupling capacitance and >8mm creepage distance ensure robust safety margins. In application, it excels in switchmode power supply feedback loops, microprocessor and computer peripheral interfaces, digital logic transmission, and industrial control systems. Its wide -55°C to +100°C operating range and compact SMD profile also suit space-constrained designs like power adapters and isolated sensor modules where reliable galvanic isolation is critical.
