TLP183(Y-TPL,E

Overview

The TLP183(Y-TPL,E is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It features a GaAlAs LED coupled to an NPN phototransistor within a compact 6-SOP surface-mount package. The device provides high isolation voltage of 3750Vrms, ensuring reliable signal transmission across isolated circuits. Key electrical parameters include a maximum collector-emitter voltage of 80V, a DC forward current limit of 50mA, and a typical forward voltage of 1.25V. The unit supports a wide operating temperature range from -55°C to 125°C, with switching times of approximately 3µs for both turn-on and turn-off.

Feature Summary

• Integrates a GaAlAs infrared LED with an NPN phototransistor for efficient optical coupling.
• Provides robust electrical isolation with a rated voltage of 3750Vrms between input and output sections.
• Designed for surface-mount technology in a small 6-SOP package to save board space.
• Capable of operation across an extended industrial temperature range up to 125°C.

Applications

• Signal isolation in general-purpose digital communication interfaces
• Interface circuits for microcontrollers and logic systems
• Power supply feedback loops requiring galvanic isolation

Procurement Notes

Verify the specific suffix (Y-TPL,E) against the manufacturer's latest datasheet to confirm compliance with RoHS directives and halogen-free requirements. Ensure the ordering code matches the required tape-and-reel or cut-tape packaging format. Cross-reference the component marking with official Toshiba documentation to prevent counterfeit parts. Confirm that the supplier provides traceability documents consistent with the original equipment manufacturer's standards.

Selection Notes

Select this component when a single-channel transistor output is required for moderate-speed signal isolation. The 80V output voltage rating suits low-voltage logic interfacing applications. Consider the 50mA forward current capability for driving standard LED inputs without excessive power dissipation. The 6-SOP footprint is suitable for automated assembly processes where space constraints are critical compared to larger DIP packages.

Part Context

This part belongs to the TLP183 family of transistor-output optocouplers from Toshiba. Variants within this series differ primarily in packaging options, such as bulk versus reel, and specific environmental certifications indicated by suffixes like GRL, BLL, or GB. The core electrical characteristics remain consistent across the family, offering a standardized solution for basic isolation tasks in consumer and industrial electronics.
