TLP184(TPL,SE

Overview

The TLP184(TPL,SE is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It features a 6-SOP surface-mount package with four leads. Key electrical parameters include an isolation voltage of 3750Vrms, a maximum collector-emitter voltage of 80V, and a continuous collector current of 50mA per channel. The device supports AC or DC input signals with a typical forward voltage of 1.25V. Switching characteristics include typical rise and fall times of 2µs and 3µs, respectively, and typical on/off times of 3µs. The current transfer ratio ranges from 50% to 600% at a forward current of 5mA.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits using infrared LED and phototransistor technology.
• Supports both AC and DC input signal types for versatile interface applications.
• Features low saturation voltage and fast switching speeds suitable for digital signal transmission.

Applications

• Digital signal isolation in industrial control systems
• Interface circuits for microcontrollers and logic gates
• Power supply feedback loops requiring galvanic isolation

Procurement Notes

Verify the specific suffix (TPL,SE) against the manufacturer's datasheet to confirm the tape and reel packaging configuration. Ensure the component meets required RoHS compliance standards for your assembly process. Cross-reference the ordering code with official distributor catalogs to confirm availability and lead times before finalizing procurement plans.

Selection Notes

Select this component when a single-channel transistor output isolator with 3750Vrms isolation capability is required. Consider the 6-SOP package dimensions for PCB layout constraints. Evaluate the current transfer ratio range and switching speed requirements against the target application's performance needs compared to other TLP184 variants.

Part Context

This part belongs to the TLP184 family of transistor output optocouplers from Toshiba. Variants within this family share similar core electrical specifications but differ in packaging options such as tube or tape and reel, and specific color codes for identification. The TLP184 series is designed for general-purpose isolation tasks in consumer and industrial electronics.

Replacement Considerations

Direct substitutes may include other TLP184 variants with different packaging suffixes, provided the pinout and electrical ratings remain identical. Verify compatibility with any alternative components offering similar isolation voltage and current transfer ratios.
