Overview
The TCMT1100 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output and is housed in a surface-mount SOP-4 package. The device provides an isolation voltage of 3750 Vrms, with a maximum collector-emitter voltage of 70 V and a maximum collector current of 50 mA. The forward current rating is 60 mA, and the typical forward voltage is 1.35 V. The current transfer ratio ranges from 50% to 600%. Operating temperatures span from -40°C to +100°C.
Feature Summary
- Single-channel configuration with NPN phototransistor output
- High isolation voltage capability of 3750 Vrms
- Surface-mount SOP-4 packaging for automated assembly
Applications
- General-purpose signal isolation
- Industrial control systems
- Consumer electronics interfaces
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific ordering suffixes against official Vishay documentation prior to purchase. Ensure storage conditions adhere to moisture sensitivity level requirements to maintain device integrity during assembly processes.
Selection Notes
Select this component for applications requiring compact surface-mount isolation with high voltage tolerance. Consider the 50 mA output current limit and 70 V collector-emitter voltage when designing load circuits. Evaluate thermal management needs given the operating temperature range up to 100°C and power dissipation constraints inherent to the small outline package.
Part Context
The TCMT1100 belongs to the TCMT110 series of transistor output optocouplers from Vishay. This series includes variants such as the TCMT1101, which shares similar electrical characteristics but may differ in packaging or specific parameter tolerances. These components are designed for reliable galvanic isolation in digital and analog signal transmission environments.
Replacement Considerations
The TCMT1101 is a documented substitute within the same product family, offering comparable performance in a similar surface-mount format. Verify pinout compatibility and exact electrical specifications against the target application requirements before substitution.
