LDA102S

Transistor, Photovoltaic Output Optoisolators Overview

The LDA102S is a unidirectional-input optocoupler featuring a single NPN phototransistor output with an integrated base terminal. It provides a 3750Vrms isolation barrier between input and output channels. The device operates within a temperature range of -40°C to +85°C and utilizes a surface-mount 6-SMD package. Key electrical parameters include a minimum current transfer ratio of 50% at a forward current of 1 mA, a maximum collector-emitter voltage of 30 V, and a power dissipation rating of 150 mW.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'S' indicates the surface-mount configuration when sourcing replacements. Confirm that the required current transfer ratio meets the system's minimum threshold, as values can vary based on operating conditions. Ensure the selected component complies with relevant RoHS directives for environmental standards.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a low-cost, general-purpose optocoupler with a base-accessible output is required. The integrated base allows for faster switching or linear operation compared to standard configurations. Consider the 3750Vrms isolation rating for safety-critical applications requiring robust barrier protection.

Transistor, Photovoltaic Output Optoisolators Part Context

The LDA102S belongs to the LDA100 series of transistor-output optocouplers manufactured by IXYS Integrated Circuits Division. This series is designed for cost-effective isolation solutions where moderate speed and high reliability are prioritized. The S variant specifically denotes the surface-mount package option within the broader family.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Compatible substitutes include the LDA102 (through-hole) for pin-compatible board revisions if packaging changes are acceptable. Verify that alternative components maintain the same 3750Vrms isolation rating and similar current transfer characteristics.
