Overview
The TLP187(E) is a transistor output optocoupler featuring a Darlington transistor structure. It provides high isolation with a rated voltage of 3750Vrms and supports a collector-emitter voltage of 300V. The device delivers an output current of 150mA with a minimum current transfer ratio of 1000%. It operates within a temperature range of -55°C to +110°C, utilizing a compact SO-6 package.
Feature Summary
- High collector-emitter breakdown voltage suitable for high-voltage switching applications
- Enhanced insulation safety compliance with reinforced insulation standards
- Compact surface-mount packaging reducing installation height
Applications
- Programmable logic controller (PLC) output modules
- Factory automation interface circuits
- Air conditioning control systems
Procurement Notes
Verify the specific suffix against official Toshiba documentation to confirm pinout and electrical tolerances. Ensure the selected variant matches the required insulation class and package dimensions for your PCB layout. Cross-reference datasheet parameters for current transfer ratio and isolation voltage before integration.
Selection Notes
Select this component when high voltage isolation and significant current gain are required in a small form factor. The Darlington configuration offers high sensitivity but slower switching speeds compared to standard transistors. Verify thermal management requirements for operation near the maximum junction temperature limit.
Part Context
This device belongs to Toshiba's general-purpose optocoupler lineup designed for industrial and consumer applications. It serves as a successor to older models like the TLP127, offering improved insulation thickness and reduced profile while maintaining robust performance characteristics for signal isolation.
Replacement Considerations
The TLP127 is documented as a predecessor that can be replaced by this series due to compatible pad sizes. Verify mechanical footprint compatibility and ensure the replacement meets the specific insulation voltage requirements of the original design.
