TLP185(Y-TPL,SE

Overview

The TLP185(Y-TPL,SE) is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It integrates an infrared LED with a phototransistor in a compact surface-mount package. Key electrical parameters include a minimum isolation voltage of 3750Vrms, a collector-emitter breakdown voltage of 80V, and a maximum DC forward current of 50mA. The device features a typical rise time of 3µs and fall time of 3µs. It operates within a temperature range of -55°C to 110°C and offers a current transfer ratio ranging from 50% to 150% at 5mA input.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits using infrared light transmission.
• Delivers fast switching performance with microsecond-level rise and fall times for signal integrity.
• Ensures reliable operation across a wide industrial temperature range without derating.

Applications

• Digital logic signal transmission and level shifting
• Power supply control and switching circuits
• Electrical insulation between systems and impedance transformation

Procurement Notes

Verify the specific suffix (Y-TPL,SE) against official Toshiba documentation to confirm current transfer ratio grades and packaging specifications. Ensure compliance with RoHS directives and check for any recent product change notifications that may affect pinout or material composition before finalizing procurement orders.

Selection Notes

Select this component when high isolation voltage and moderate speed are required for single-channel applications. Compare the 50-150% CTR range against circuit requirements to ensure adequate drive capability. Consider the SOP4 footprint constraints and thermal management needs for the -55°C to 110°C operating environment during design integration.

Part Context

This part belongs to the TLP series of small outline optocouplers designed for surface mount technology. It serves as a compact solution for isolating low-power control signals from higher voltage loads. The series is widely used in consumer electronics and industrial equipment where space efficiency and safety certification are critical design factors.

Replacement Considerations

Direct substitutes must match the 6-SOP package, 3750Vrms isolation, and similar CTR ranges. Verify pin compatibility and thermal characteristics before swapping. Generic replacements may lack the specific safety certifications held by this Toshiba component.
