TLP184(Y-TPL,SE

Overview

The TLP184(Y-TPL,SE is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It features an infrared LED coupled to a phototransistor within a compact surface-mount package. The device provides high isolation voltage of 3750Vrms between input and output circuits. Key electrical parameters include a collector-emitter voltage of 80V, a collector current of 50mA, and a forward current of 20mA. The typical rise and fall times are 2µs and 3µs respectively, with a current transfer ratio ranging from 50% to 600% at 5mA input.

Feature Summary

• Provides galvanic isolation via infrared light transmission between input and output sections
• Features a compact surface-mount design suitable for automated assembly processes
• Delivers fast switching performance with microsecond-level response times

Applications

• Signal isolation in industrial control systems
• Interface circuits for microprocessors and logic devices
• Power supply feedback loops requiring voltage isolation

Procurement Notes

Verify the specific suffix (Y-TPL,SE) against official Toshiba documentation to confirm tape and reel packaging specifications. Ensure that the requested variant matches the required moisture sensitivity level and reflow soldering profile. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity before placing orders.

Selection Notes

Select this component when a single-channel isolation solution with moderate speed is required. Consider the 80V output voltage limit and 50mA current capacity for load compatibility. Evaluate the 3750Vrms isolation rating against system safety requirements. Compare current transfer ratio specifications if signal amplification is needed without external components.
