TLP385(BL-TPL,E

Transistor, Photovoltaic Output Optoisolators Overview

The TLP385(BL-TPL,E is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It integrates a Gallium Arsenide infrared LED with a phototransistor in a compact 6-SO, 4-lead surface-mount package. The device provides high isolation voltage of 5000Vrms and supports a collector-emitter voltage of 80V. It features a typical forward voltage of 1.25V and a maximum DC forward current of 50mA. The output channel can handle up to 50mA with a saturation voltage drop of 300mV maximum. Switching characteristics include typical turn-on/turn-off times of 3µs and rise/fall times of 2µs/3µs. The Current Transfer Ratio ranges from 200% to 400% at 5mA input. It operates within a temperature range of -55°C to 110°C.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix designation to ensure correct packaging configuration, as variations such as TR, CT, or EKR denote different reel or cut-tape formats. Confirm RoHS3 compliance status and MSL level 1 classification during sourcing. Cross-reference the manufacturer part number against official distributor catalogs to avoid confusion with similar family members like TLP385(GB-TPL,E which may have distinct CTR specifications.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high isolation voltage and small form factor are required for surface-mounted designs. Ensure the application current does not exceed the 50mA output limit and that the 80V collector-emitter rating accommodates the load voltage. Consider the 200%-400% CTR range for drive circuit design. Verify thermal management requirements given the wide operating temperature span and surface mount thermal dissipation characteristics.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the TLP385 series of photocouplers featuring GaAs infrared LEDs and photo-transistors. The series is designed for high-density applications where space constraints necessitate thin packages compared to standard DIP types. The BL suffix typically indicates a specific binning or packaging variant within the broader TLP385 product line offered by Toshiba Semiconductor and Storage.
