TLP183(E

Overview

The TLP183(E) is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It provides electrical isolation with a rated voltage of 3750Vrms. The device features a maximum collector-emitter voltage of 80V and can handle an output current of 50mA per channel. Typical switching characteristics include a turn-on time of 3µs and a turn-off time of 3µs, with rise and fall times of 2µs and 3µs respectively. The forward voltage is typically 1.25V at a maximum DC forward current of 50mA. The component operates within a temperature range of -55°C to 125°C and is available in a 6-SOP surface-mount package.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits using infrared LED and phototransistor technology.
• Delivers fast switching performance suitable for digital logic transmission and signal transfer applications.

Applications

• Digital logic signal transmission and level shifting
• Power supply control and switching circuits
• Electrical insulation between circuit stages or systems

Procurement Notes

Verify the specific suffix (e.g., GB, GRL, BL, Y, BLL) against design requirements, as these indicate variations in Current Transfer Ratio (CTR) ranges and packaging types such as tape-and-reel or tube. Confirm RoHS compliance status through official manufacturer documentation prior to ordering. Ensure the selected variant matches the required isolation voltage and operating temperature specifications for the target application environment.

Selection Notes

Select the appropriate suffix based on the required CTR range; for instance, variants like TLP183(BL) offer higher CTR compared to standard versions. Consider the packaging format (reel, cut tape, or tube) relative to assembly line capabilities. Verify that the 80V output voltage rating and 50mA current capacity meet the load requirements. Ensure the 6-SOP footprint aligns with the PCB layout constraints.

Part Context

The TLP183 series comprises various transistor output optocouplers from Toshiba, differentiated by suffixes indicating CTR bins and packaging options. These devices are designed for general-purpose isolation in industrial and consumer electronics. The base model shares core electrical characteristics, while suffixes define specific performance tolerances and supply formats, allowing designers to optimize for cost and manufacturing efficiency.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the source material. Designers should consult Toshiba's official selection guide or distributor catalogs for cross-reference data when identifying compatible alternatives.
