Overview
The TCMT4100T0 is a quad phototransistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features four independent channels within a 16-SOP surface-mount package. The device provides an isolation voltage of 3750Vrms and operates across a temperature range of -40°C to +100°C. Key electrical parameters include a maximum DC forward current of 60mA, a collector-emitter saturation voltage of 300mV, and a typical turn-on/turn-off time of 6µs/5µs. The current transfer ratio ranges from 100% to 600% at a forward current of 5mA.
Feature Summary
- Quad channel configuration for multi-signal isolation
- High isolation voltage rating for safety compliance
- Wide operating temperature range suitable for industrial environments
Applications
- Industrial process control systems
- Communication equipment signal isolation
- Power supply feedback circuits
Procurement Notes
Verify the specific suffix T0 against the official datasheet to confirm the tape and reel packaging format. Ensure the ordering part number matches the required quantity increments defined by the manufacturer. Cross-reference the safety agency approval numbers listed in the documentation to confirm compliance with relevant international standards for your specific application region.
Selection Notes
Select this component when high-density quad isolation is required in a small surface-mount footprint. Compare the current transfer ratio and switching speeds against alternative quad optocouplers to ensure compatibility with the driving circuit requirements. Verify that the 3750Vrms isolation rating meets the system's safety clearance and creepage distance specifications.
Part Context
This component belongs to the TCMT4100 series, which includes variants like the TCMT4106. The TCMT4100 model serves as the safety application reference number for consulting agency documents. The series is designed for general-purpose digital signal isolation in compact electronic designs requiring multiple isolated channels.
Replacement Considerations
Check for direct pin-compatible substitutes within the same Vishay TCMT410x family. Verify that any replacement maintains the same 16-SOP package dimensions and electrical characteristics such as CTR and isolation voltage.
