LDA110STR

Transistor, Photovoltaic Output Optoisolators Overview

The LDA110STR is a bidirectional-input optocoupler manufactured by IXYS Integrated Circuits Division. It features a Darlington transistor output with an integrated base terminal for enhanced switching control. The device provides high isolation voltage of 3750Vrms and supports AC or DC input signals. Key electrical parameters include a minimum current transfer ratio (CTR) of 300% at 1mA forward current, a maximum collector-emitter saturation voltage of 500mV, and typical turn-on/turn-off times of 7µs and 20µs respectively. It operates within a temperature range of -40°C to 85°C and is housed in a 6-SMD鸥翼 package.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix STR indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the bidirectional input requirement matches your circuit design before procurement. Check for any recent product change notices affecting pinout or specifications.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when bidirectional input flexibility is required alongside high CTR for efficient drive currents. The integrated base allows for faster switching compared to standard Darlington outputs without base access. Consider the 6-SMD footprint for surface-mount assembly constraints. Evaluate thermal management needs based on the specified operating temperature range.

Transistor, Photovoltaic Output Optoisolators Part Context

The LDA110 belongs to IXYS's line of optoisolators designed for general-purpose isolation applications. It complements other models like the LDA100STR but offers superior current transfer characteristics due to its Darlington architecture. This series is commonly used in environments demanding reliable galvanic isolation between low-voltage control logic and higher-voltage power stages.
