TLP183(GB,E

Overview

The TLP183(GB,E is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It features a 6-SOP surface-mount package with four leads. The device provides an isolation voltage of 3750Vrms between input and output circuits. Key electrical parameters include a maximum collector-emitter voltage of 80V and a continuous output current of 50mA per channel. The typical forward voltage is 1.25V, with a maximum DC forward current of 50mA. The saturation voltage is limited to 300mV. Switching characteristics include typical turn-on and turn-off times of 3µs, and rise/fall times of 2µs and 3µs respectively. The Current Transfer Ratio ranges from 100% to 600% depending on the specific suffix variant. Operating temperature spans -55°C to 125°C.

Feature Summary

• Provides high-voltage electrical isolation via infrared LED and phototransistor coupling
• Designed for digital logic transmission and impedance transformation
• Suitable for power control and switching applications requiring circuit insulation

Applications

• Digital logic signal transmission and level shifting
• Power supply control and switching circuits
• Electrical insulation between separate system circuits
• Impedance transformation in isolated interfaces

Procurement Notes

Verify the specific suffix code (e.g., GB, GRL, BL) to ensure correct Current Transfer Ratio specifications, as variants differ significantly. Confirm RoHS compliance status and MSL rating prior to ordering. Check manufacturer lead times and availability through authorized distributors. Ensure ESD handling procedures are followed during storage and assembly. Validate package dimensions against PCB footprint requirements.

Selection Notes

Select based on required CTR range and isolation voltage needs. The GB suffix offers a broad CTR range suitable for general-purpose switching. Consider thermal management if operating near the upper temperature limit. Verify that the 50mA output current meets load requirements. Ensure the 6-SOP package fits the available board space. Compare switching speeds if high-frequency operation is necessary.

Part Context

This component belongs to the TLP183 series of low-current input transistor optocouplers. It is part of Toshiba's isolator product line designed for compact surface-mount applications. The series includes various suffixes indicating different CTR grades and packaging options. It serves as a standard solution for galvanic isolation in consumer and industrial electronics where small form factors are critical.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source documentation. Direct replacements should be verified against pinout compatibility, isolation voltage ratings, and CTR specifications. Cross-reference with Toshiba's official selection guides for equivalent series components.
