- PTH12030W TYPICAL CHARACTERISTICS (VI = 12 V)Characteristic data has been developed from actual products tested at 25C. This data is considered typical data for the converter. Applies to , , and .SOA curves represent the conditions at which internal components are at or below the manufacturer’s maximum operating temperatures. Derating limits apply to modules soldered directly to a 4 in. 4 in. double-sided PCB with 1 oz. copper. For surface mount products (AS and AZ suffix), multiple vias (plated through holes) are required to add thermal paths around the power pins. Please refer to the mechanical specification for more information. Applies to .
