LTV-816S-TA1

Transistor, Photovoltaic Output Optoisolators Overview

The LTV-816S-TA1 is a single-channel transistor-output optocoupler manufactured by Lite-On Inc. It features a gallium arsenide infrared LED coupled to an NPN silicon phototransistor in a compact 4-SMD gull-wing package. The device provides high isolation voltage of 5000Vrms and supports a maximum collector-emitter voltage of 80V with a continuous output current of 50mA. Key electrical parameters include a typical forward voltage of 1.2V, a DC forward current limit of 50mA, and a saturation voltage of 200mV. The unit offers a current transfer ratio ranging from 50% to 600% at 5mA input, with rise and fall times of 4µs and 3µs respectively, operating within a temperature range of -50°C to 110°C.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix TA1 corresponds to the tape-and-reel packaging configuration as defined by the manufacturer. Confirm RoHS compliance status and safety certifications such as UL, CSA, or VDE are present on the official datasheet before integration. Ensure the ordering part number matches the exact package type and lead finish requirements for the intended surface-mount assembly process.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a single-channel transistor output with high isolation voltage is required in a small surface-mount footprint. Consider the 5000Vrms isolation rating and the 80V collector-emitter voltage for applications demanding strong barrier protection. Evaluate the CTR range and switching speeds against the system's timing constraints and logic level requirements.
