Procurement Notes

Verify the specific suffix K-A against official Renesas documentation to confirm lead bending type packaging and compliance details. Confirm availability status as limited supply or factory special order may apply. Ensure RoHS compliance requirements match project specifications before procurement.

Selection Notes

Select this component when high CTR and fast switching speeds are required in a surface mount package. Compare against standard DIP variants if through-hole mounting is preferred. Verify thermal dissipation limits and operating temperature range suitability for the target environment.

Part Context

This part belongs to the PS2562L series of high isolation voltage darlington transistor type multi photocouplers. It utilizes a GaAs light emitting diode coupled with an NPN silicon darlington connected phototransistor. The L-series designation indicates a lead bending type gull-wing package suitable for surface mount applications.
