Overview
The TLP184(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 6-SOP surface-mount package. The device provides high isolation voltage of 3750Vrms, ensuring reliable signal transmission between isolated circuits. Key electrical parameters include a collector-emitter voltage of 80V, a collector current of 50mA, and a typical propagation delay of 3µs for both turn-on and turn-off times. The unit operates within a temperature range of -55°C to 110°C.
Feature Summary
- Provides galvanic isolation between input and output circuits using optical transmission.
- Features a compact 6-SOP surface-mount package suitable for automated assembly.
- Offers high common-mode transient immunity due to internal structural design.
Applications
- Signal isolation in general-purpose digital communication interfaces.
- Input stage isolation for solid-state relays and switching power supplies.
- Interface circuits for microcontrollers and logic gates requiring noise immunity.
Procurement Notes
Verify the specific suffix (SE) against the manufacturer's latest datasheet to confirm pinout configuration and packaging type. Ensure that the ordering quantity aligns with the standard factory pack size to avoid partial reel issues. Confirm RoHS compliance status and lead times directly with authorized distributors prior to finalizing procurement plans.
Selection Notes
Select this component when a single-channel transistor output is required for low-speed signal isolation. Consider the 80V collector-emitter voltage rating and 50mA output current capability for load matching. Evaluate the 3750Vrms isolation voltage requirement against system safety standards. Compare propagation delays if higher speed performance is necessary for the application.
Part Context
This part belongs to the TLP184 family of transistor output optocouplers from Toshiba. Variants such as TLP184(TPL,SE) or TLP184(GB,SE) may differ in packaging format or specific CTR ranges while maintaining core electrical characteristics. The family is designed for general-purpose isolation applications where cost-effectiveness and reliability are prioritized over high-speed data transmission.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires consulting official Toshiba replacement guides or distributor compatibility lists to ensure equivalent electrical and mechanical specifications.
