Overview
The TLP127(TEE-TPLS,F) is a single-channel optocoupler featuring an infrared LED input and a Darlington phototransistor output. It provides electrical isolation with a rated voltage of 2500Vrms. The device supports a maximum collector-emitter voltage of 300V and can handle an output current of 150mA. Key timing parameters include a turn-on time of 50µs and a turn-off time of 15µs at standard test conditions. The forward voltage is typically 1.15V, with a maximum DC forward current of 50mA. It operates within a temperature range of -55°C to 100°C.
Feature Summary
- Integrates an infrared LED with a high-gain Darlington phototransistor for enhanced sensitivity.
- Provides robust electrical isolation between input and output circuits.
- Features a compact surface-mount package suitable for automated assembly.
Applications
- Programmable logic controllers
- DC-output modules
- Telecommunications equipment
Procurement Notes
Verify the exact suffix against official Toshiba documentation, as 'TEE-TPLS' may indicate specific tape-and-reel or lead-free variations. Confirm RoHS compliance status and moisture sensitivity level prior to ordering. Ensure the supplier provides valid traceability documents matching the manufacturer's part numbering system.
Selection Notes
Select this component when high current transfer ratio is required due to the Darlington output structure. Consider the slower switching speed compared to standard transistor outputs. Verify that the 300V collector voltage meets the load requirements. Check if the SOP-4 footprint aligns with the PCB design constraints.
Part Context
This part belongs to Toshiba's small outline coupler series designed for surface mount applications. It replaces older through-hole variants in modern compact designs. The family focuses on providing reliable isolation for industrial and communication systems while maintaining a low profile.
Replacement Considerations
Public confirmed substitute: IS352-AXW (Anxin Micro Semiconductor). Note that alternative parts may differ in pinout compatibility or electrical characteristics such as current transfer ratio and saturation voltage.
