Key Features
- Dual-channel configuration with 2 separate optocoupler elements in a single SOP-8 package saves PCB space compared to two single-channel devices
- 2500 V isolation voltage rating provides robust galvanic separation between input and output circuits in safety-critical applications
- Surface-mount SOP-8 package with UL recognized certification supports automated PCB assembly and meets safety agency requirements
Applications
The TLP2108(F) is used in industrial control systems, power supply feedback loops, and programmable logic controller I/O interfaces where galvanic isolation between 2 separate signal channels is required. Its 2500 V isolation rating makes it suitable for isolating microcontroller outputs from high-voltage drive circuits in motor controllers, inverters, and relay drivers. The dual-channel SOP-8 format reduces component count and PCB area in designs requiring multiple isolated signal paths.

Frequently Asked Questions
What isolation voltage does the TLP2108(F) provide and what safety certifications does it carry?
The TLP2108(F) provides a maximum isolation voltage of 2500 V between the input LED side and the output transistor side of each channel. It carries UL recognition, which validates its suitability for use in safety-critical applications such as industrial automation equipment, medical power supplies, and consumer appliances where regulatory compliance for galvanic isolation is required.
How many isolated channels does the TLP2108(F) integrate and how does that reduce BOM complexity?
The TLP2108(F) integrates 2 separate optocoupler channels in a single SOP-8 surface-mount package. Using one dual-channel device instead of 2 single-channel optocouplers reduces the bill of materials by 1 component, cuts PCB footprint by roughly 50%, and simplifies layout routing for paired isolation requirements such as transmit and receive paths in isolated RS-485 or CAN bus interface circuits.
What are the input LED forward current and output on-state current limits for the TLP2108(F)?
The TLP2108(F) has a maximum forward input current of 20 mA (0.02 A) for the LED drive side and a maximum on-state output current of 25 mA (0.025 A) for the phototransistor output. These parameters define the drive and load constraints for each isolated channel, ensuring the device operates within its safe operating area when used in logic-level signal isolation between 3.3 V or 5 V microcontroller outputs and downstream circuits.
For which industrial or power-electronics applications is the TLP2108(F) dual-channel optocoupler most appropriate?
The TLP2108(F) is well suited for isolated I/O interfaces in industrial PLCs, gate drive signal isolation in DC-DC converters, feedback isolation in SMPS circuits, and relay drive control in building automation systems. Its 2500 V isolation rating and SOP-8 package meet the clearance and creepage requirements for reinforced insulation in equipment operating at mains voltages up to 250 V AC, covering a broad range of low-power industrial isolation needs.
