TCLT1113

Overview

The TCLT1113 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor with a base terminal for enhanced switching performance. The device provides 5000Vrms isolation voltage and operates within a temperature range of -55°C to 110°C. Key electrical parameters include a maximum collector-emitter voltage of 70V, a DC forward current of 60mA, and a typical forward voltage of 1.25V. The current transfer ratio ranges from 100% to 200% at 10mA input. Switching characteristics include typical turn-on/turn-off times of 6µs/5µs and rise/fall times of 3µs/4.7µs. It is housed in a 6-SOP, 5-pin surface-mount package.

Feature Summary

• Integrated base terminal on the phototransistor output for improved switching speed and linearity
• High isolation voltage rating of 5000Vrms for robust signal separation
• Wide operating temperature range suitable for industrial environments
• Surface-mount 6-SOP package design for compact circuit board integration

Applications

• Industrial automation control systems requiring galvanic isolation
• Signal transmission between microcontrollers and high-voltage loads
• Power supply feedback loops for voltage regulation
• Solid-state relay driver circuits

Procurement Notes

Verify the specific ordering suffix (e.g., TR for tape and reel, CT for cut tape) to ensure correct packaging quantity and handling requirements. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the procurement channel provides valid traceability for the Vishay Semiconductor Opto Division part number TCLT1113. Check for any recent product change notifications that may affect pinout or specifications.

Selection Notes

Select this component when base-driven phototransistor outputs are required for faster switching compared to standard phototransistors. Consider the 70V collector-emitter voltage limit for load compatibility. Evaluate the 5000Vrms isolation requirement against system safety standards. The 6-SOP package dimensions must fit the available PCB footprint. Verify thermal management needs given the 110°C maximum junction temperature rating.

Part Context

The TCLT1113 belongs to the TCLT11xx series of transistor output optocouplers from Vishay. This series is designed for general-purpose isolation applications where moderate speed and high reliability are needed. It shares similar packaging and basic functionality with other members like the TCLT1103 and TCLT1117, but differs in specific electrical characteristics such as current transfer ratio and switching speeds. The series supports various surface-mount configurations for automated assembly.

Replacement Considerations

Direct replacements should be sought from the same Vishay TCLT11xx family, such as the TCLT1103 or TCLT1117, ensuring pin compatibility and electrical parameter alignment. Cross-manufacturer substitutes require careful verification of isolation voltage, CTR, and package dimensions. Any alternative must maintain the base-terminal feature if switching speed is critical.
