Overview
The TLP187(TPL,E is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It integrates an InGaAs infrared LED with a Darlington transistor output, housed in a compact SO-4 (SOP-4) surface-mount package. The device provides high isolation voltage of 3750Vrms and supports a collector-emitter voltage of 300V. Key electrical parameters include a typical forward voltage of 1.25V, maximum DC forward current of 50mA, and output current capability of 150mA. It features a minimum current transfer ratio of 1000% at 10mA input, with rise and fall times of 40µs and 15µs respectively. Operating temperature range spans from -55°C to +110°C.
Feature Summary
- High current transfer ratio enabled by Darlington output structure for efficient signal transmission
- High breakdown voltage between collector and emitter suitable for high-voltage switching applications
- Robust insulation performance with 3750Vrms isolation voltage for noise immunity
- Compact surface-mount packaging designed for automated assembly processes
Applications
- Output modules for programmable controllers requiring 100VDC support
- Industrial control systems needing high-gain transistor switching
- Power supply circuits requiring galvanic isolation
- Signal transmission interfaces in noisy electrical environments
Procurement Notes
Verify the specific suffix (TPL,E) against official Toshiba documentation to confirm tape-and-reel packaging and RoHS compliance status. Ensure the ordering part number matches the required SOP-4 variant. Cross-reference datasheet revisions to confirm parameter consistency, particularly regarding current transfer ratio and isolation ratings, before finalizing procurement specifications.
Selection Notes
Select this component when high current gain and high voltage blocking capability are required in a small footprint. The Darlington configuration offers superior sensitivity compared to standard phototransistors, making it suitable for low-input current applications. Consider the slower switching speed relative to logic outputs when designing for high-frequency signals. Verify thermal management requirements within the specified operating temperature range.
Part Context
This device belongs to Toshiba's TLP187 series of transistor output optocouplers. It shares the same core functional architecture as other variants in the family but differs in packaging and reel specifications. The TPL,E suffix typically denotes tape-and-reel packaging for surface-mount technology, distinguishing it from tube-packaged equivalents like the TLP187(E.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult Toshiba's official replacement guide or contact technical support for verified cross-reference data.
