TLP183(BLL,E

Overview

The TLP183(BLL,E is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It integrates an infrared LED and a phototransistor within a compact 4-SOP package to provide electrical isolation between input and output circuits. The device features a high isolation voltage of 3750Vrms, ensuring robust safety standards for signal transmission. It operates with a DC input type and supports a maximum output voltage of 80V per channel. The unit delivers a typical current transfer ratio ranging from 200% to 400% at a forward current of 500µA. It functions reliably across an extended temperature range of -55°C to 125°C.

Feature Summary

• Provides galvanic isolation via infrared LED and phototransistor integration
• Supports high voltage insulation up to 3750Vrms
• Designed for low current input applications
• Utilizes surface mount 4-SOP packaging

Applications

• Digital logic signal transmission and conversion
• Power supply control and switching circuits
• Electrical insulation between circuit stages
• Impedance transformation in isolated systems

Procurement Notes

Verify the specific suffix BLL against official Toshiba documentation to confirm pinout and performance characteristics relative to other variants in the TLP183 series. Ensure compatibility with RoHS3 regulations as indicated for this product line. Confirm package dimensions match the 4-SOP specification before integration into PCB layouts.

Selection Notes

Select this component when high isolation voltage is required in a minimal footprint. The 4-SOP package offers space efficiency compared to wider SOP options. Consider the current transfer ratio specifications at low drive currents if designing for energy-efficient or low-power input stages. Verify thermal management requirements for operation near the upper temperature limit.

Part Context

This part belongs to the TLP183 family of low-current input transistor optocouplers. The BLL suffix typically denotes specific packaging or material compliance variations within the Toshiba portfolio. These devices are engineered for general-purpose isolation tasks where small size and high reliability are prioritized over high-speed switching capabilities.

Replacement Considerations

Direct substitutes may include other Toshiba TLP183 variants such as TLP183(BL,E or TLP183(GB,E, provided the package and electrical parameters align. Cross-referencing datasheets is essential to ensure identical isolation ratings and pin configurations.
