LDA102

Transistor, Photovoltaic Output Optoisolators Overview

The LDA102 is a single-channel transistor output optocoupler manufactured by IXYS Integrated Circuits Division. It features an NPN phototransistor with a base connection for enhanced switching performance. The device provides a high isolation voltage of 3750Vrms between the input LED and output transistor. Key electrical parameters include a minimum current transfer ratio of 50% at a forward current of 1 mA, a maximum collector-emitter voltage of 50 V, and a collector-emitter saturation voltage of 500 mV. The unit operates within a temperature range of -40°C to +85°C and is housed in a standard 6-DIP through-hole package.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify component authenticity against official IXYS datasheets when sourcing. Confirm that the received units match the specific LDA102 designation to ensure correct pinout and electrical characteristics. Check for any obsolescence notices or lifecycle status updates from the manufacturer prior to finalizing procurement plans. Ensure storage conditions comply with moisture sensitivity levels if applicable.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a dedicated base drive is required to optimize switching times in transistor output applications. Compare the 50% CTR specification against system requirements for signal integrity at low input currents. Evaluate the 3750Vrms isolation rating against safety standards relevant to the target application environment. Consider the physical dimensions of the 6-DIP package for PCB layout constraints.

Transistor, Photovoltaic Output Optoisolators Part Context

The LDA102 belongs to the family of transistor output optocouplers produced by IXYS Integrated Circuits Division. It serves as a discrete solution for isolating low-voltage digital signals from higher voltage power stages. The inclusion of a base lead distinguishes it from standard phototransistor optocouplers, offering designers additional control over the output stage's dynamic response characteristics.
