TCMT1101

Overview

The TCMT1101 is a single-channel optoisolator manufactured by Vishay Semiconductor Opto Division, featuring a transistor output. It provides an isolation voltage of 3750Vrms and operates within a temperature range of -40°C to 100°C. The device supports a maximum output voltage of 70V and a continuous output current of 50mA per channel. Typical switching characteristics include a turn-on time of 9.5µs and a turn-off time of 8.5µs. The rise and fall times are typically 5.5µs and 7µs, respectively. The component utilizes a 4-SOP surface-mount package with a width of 4.40mm.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits using optical coupling technology.

Applications

• General-purpose signal isolation in industrial control systems
• Interface circuits for microprocessors and logic gates
• Power supply feedback loops requiring galvanic separation

Procurement Notes

Verify the specific ordering suffix (e.g., TR, CT, DKR) to confirm the required packaging format such as tape and reel or cut tape. Ensure the procurement source explicitly lists the manufacturer as Vishay Semiconductor Opto Division to guarantee authenticity. Cross-reference the datasheet revision date against project requirements to confirm compliance with current specifications. Confirm RoHS3 compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a single-channel transistor output isolator with 3750Vrms isolation capability is required. Consider the 50mA output current limit and 70V collector-emitter voltage rating for circuit design constraints. Evaluate the typical propagation delays of approximately 9.5µs for timing-sensitive applications. The 4-SOP package is suitable for automated surface-mount assembly processes.

Part Context

The TCMT1101 belongs to the TCMT1100 series of optoisolators from Vishay. This series includes various channel configurations and output types designed for general-purpose isolation applications. The component is currently listed as active in the manufacturer's portfolio, ensuring long-term availability for production designs.

Replacement Considerations

Public data identifies the PC3H711NIP as a similar substitute option. Note that the PC3H711NIP has different isolation ratings and is marked as obsolete in some sources. Verify pinout compatibility and electrical parameter alignment before substitution.
