• Manufacturer Part Number: ir3088a
• Description: Xphase Ic With Fault And Overtemp Detect
• Manufacturer: International Rectifier Corp.

Solder Resist
• The solder resist should be pulled away from the metal lead lands by a minimum of 0.06mm. The solder
• The minimum solder resist width is 0.13mm, therefore it is recommended that the solder resist is completely
• At the inside corner of the solder resist where the lead land groups meet, it is recommended to provide a
• The land pad should be Solder Mask Defined (SMD), with a minimum overlap of the solder resist onto the
• Ensure that the solder resist in-between the lead lands and the pad land is ≥ 0.15mm due to the high aspect
• The 4 vias in the land pad should be tented with solder resist 0.4mm diameter, or 0.1mm larger than the

Mask Defined (NSMD). Therefore pulling the S/R 0.06mm will always ensure NSMD pads.
