UL60950, 2nd Edition, (Approval pending)
The S24SP family, the highest power density (40W) industrial input range 2”X1” isolated power converter whose pinout follows industry
standard. The S24SP series comes with a host of industry-standard features, such as over current protection, over voltage protection, over
temperature protection and remote on/off. An optional heatsink is available for more extreme thermal requirements. All models have an
ultra-wide 4:1 input voltage range (9V to 36V). With operating temperature of -40°C to +85°C, it is suitable for customers’ critical applications,
such as process control and automation, transportation, data communication and telecom equipment, test equipment, medical device and
everywhere where space on the PCB is critical

Note:
1. add heat sink to help heat dissipation and increase reliability of convert operating at high ambient temperature
2. please refer derating curve while upgrate the operating temperature of converter
3. heat sink will be mounted for volume orders, separated heat sink only be supplied for prototype
4. for model with heat sink option, the recommended layout only need note the length more larger than without heat sink
Application notice:
For modules with through-hole pins, they are intended for wave soldering assembly onto system boards;
please do not subject such modules through reflow temperature profile.
Recommended layout refer below
