TIL117S1(TA)

Overview

The TIL117S1(TA) is a single-channel logic output optocoupler manufactured by Everlight Electronics. It features an infrared emitting diode coupled to a phototransistor with a base terminal for improved switching performance. The device utilizes a surface-mount SMD-6 package and provides electrical isolation of 5000 Vrms between input and output circuits. Key electrical parameters include a maximum continuous output current of 50 mA, a forward current rating of 60 mA, and a forward voltage of 1.5 V. The unit operates within a temperature range of -55°C to +100°C, with rise and fall times specified at 100 ns.

Feature Summary

• Integrated base terminal on the phototransistor enhances switching speed and sensitivity compared to standard configurations.
• Provides high-voltage electrical isolation suitable for separating low-voltage control circuits from high-voltage loads.
• Designed for surface-mount technology (SMD) assembly to facilitate automated manufacturing processes.

Applications

• Signal isolation in industrial automation control systems
• Interface circuits connecting microcontrollers to power stages
• Logic signal transmission across isolated barriers

Procurement Notes

Verify the specific suffix designation against official Everlight documentation to confirm exact packaging and compliance status. Confirm RoHS compliance details directly with the manufacturer or authorized distributor as regulatory statuses may vary by production batch. Ensure the selected variant matches the required thermal and electrical specifications for the target application environment.

Selection Notes

Select this component when enhanced switching performance is required due to the integrated base terminal. Compare the 5000 Vrms isolation rating against system safety requirements. Evaluate the SMD-6 footprint compatibility with existing PCB layouts. Consider the operating temperature range limits relative to the intended deployment environment.

Part Context

This part belongs to the H11LX series of logic output optocouplers produced by Everlight Electronics. The series is designed for applications requiring reliable signal transmission with electrical isolation. The TIL117S1(TA) variant specifically adapts the standard TIL117 transistor output structure into a surface-mount format while retaining the base connection feature.

Replacement Considerations

Consult official substitution guides for compatible equivalents. Verify pinout compatibility and electrical parameter alignment before replacing the original component in existing designs.
