AC DC Converters, Offline Switchers Procurement Notes

Verify the specific suffix 'XKLA1' against official Infineon documentation to confirm tape-and-reel packaging details, as standard BZS variants may differ. Ensure compatibility with required thermal management solutions given the DIP-7 package constraints. Confirm RoHS compliance status through the latest product quality report or datasheet revision notes provided by the manufacturer.

AC DC Converters, Offline Switchers Selection Notes

Select this component for designs requiring integrated high-voltage switching and control in a through-hole format. The 800 V breakdown voltage suits mains-connected applications. The fixed 100 kHz frequency offers a balance between efficiency and size. Consider the 0.8 Ω R_DS(on) for thermal performance at the target load current. Verify that the 39 W power limit meets the system requirements without exceeding thermal boundaries.
