TCLT1016

Overview

The TCLT1016 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output housed in a low-profile SMD 4-lead SOP-6L4 package. The device provides high isolation of 5000 Vrms and supports a maximum collector-emitter voltage of 80 V with a collector current rating of 50 mA. Key electrical parameters include a forward voltage of 1.6 V at a forward current of 60 mA, and a power dissipation capacity of 250 mW. The unit operates within a temperature range of -55°C to +100°C, offering rise and fall times of 3 µs and 4.7 µs respectively.

Feature Summary

• High insulation voltage capability of 5000 Vrms for safe signal isolation
• Low profile surface mount design suitable for space-constrained applications
• NPN phototransistor output configuration for standard switching logic

Applications

• Industrial control systems requiring galvanic isolation
• Signal transmission across isolated ground planes
• Power supply feedback loops for voltage regulation

Procurement Notes

Verify the specific Current Transfer Ratio (CTR) bin required for the application, as the TCLT series offers flexibility in CTR ranges. Confirm that the SOP-6L4 package dimensions align with the target PCB footprint. Ensure the selected supplier provides genuine Vishay components to guarantee the specified 5000 Vrms isolation rating and thermal performance characteristics are met under operational conditions.

Selection Notes

Select this component when a compact, single-channel isolator with high voltage withstand capability is needed. The 80 V collector-emitter voltage suits moderate load switching. Consider the 160-320% CTR range typical for this family if precise gain matching is required. Evaluate the 3 µs rise time against system speed requirements to ensure adequate response for the intended digital or analog signal transmission rates.

Part Context

The TCLT1016 belongs to the TCLT series of low-profile optocouplers designed for surface mount technology. This series emphasizes miniaturization while maintaining robust isolation standards. The SOP-6L4 package allows for automated assembly processes, making it suitable for high-volume manufacturing environments where board space efficiency and reliable electrical isolation are critical design constraints.

Replacement Considerations

Cross-reference with other Vishay TCLT variants such as TCLT1009 or TCLT1104 for alternative CTR specifications. Verify pinout compatibility and package dimensions before substitution. Ensure the replacement part meets or exceeds the 5000 Vrms isolation requirement and matches the thermal dissipation capabilities of the original design.
