TLP187(TPR,E

Overview

The TLP187(TPR,E is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It features a Darlington phototransistor output capable of handling a maximum collector-emitter voltage (VCEO) of 300V and a continuous collector current of 150mA. The device provides an isolation voltage rating of 3750Vrms. Key electrical parameters include a typical forward voltage (VF) of 1.25V at a maximum DC forward current (IF) of 50mA, and a maximum collector-emitter saturation voltage (VCE(sat)) of 1.2V. The unit operates within a temperature range of -55°C to 110°C and is housed in a 6-SOP surface-mount package.

Feature Summary

• High-voltage Darlington output configuration supporting up to 300V collector-emitter voltage
• Robust insulation capability with a 3750Vrms isolation voltage rating
• High current transfer efficiency enabling significant output current drive

Applications

• Industrial control systems requiring high-voltage isolation
• Power supply feedback circuits for signal isolation
• Solid-state relay driver interfaces

Procurement Notes

Verify the complete part number including suffixes such as (TPR,E) to ensure correct packaging and compliance specifications. Confirm RoHS status and moisture sensitivity level requirements against project standards. Cross-reference datasheet revision dates to validate parameter accuracy before finalizing component selection for production.

Selection Notes

Select this component when high output current capability and elevated voltage tolerance are required in a compact surface-mount form factor. The Darlington structure offers higher gain compared to standard phototransistors but exhibits slower switching speeds. Ensure input current limits are respected to maintain optimal current transfer ratio performance under varying thermal conditions.

Part Context

This device belongs to the TLP187 series of transistor output optocouplers from Toshiba. It shares the same core optical isolation architecture as other variants in the family but differs in packaging and specific electrical tolerances. The 6-SOP package allows for automated surface-mount assembly, distinguishing it from through-hole alternatives in the broader product line.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical ratings carefully if considering alternative manufacturers or different Toshiba series parts.
