If the overcurrent condition persists beyond a few milliseconds, the module will shut down into hiccup mode and restart once every 40 ms. The module operates normally when the output current goes into specified range. The typical average output current is 4 A during hiccup. Figure 31.

This module has a power good indicator output. Power good pin used positive logic and is open collector. 2. The maximum voltage pulled up externally on Power Good pin should not exceed 7V. 3. If the output voltage becomes within +10% and –5% of the target value, internal comparators detect power-good state and the power-good signal becomes high after a 1ms internal delay. 4. If the output voltage goes outside of +15% or –10% of the target value, the power-good signal becomes low after two microsecond (2-μs) internal delay. 5.

The suggested Pb-free solder paste is Sn/Ag/Cu(SAC). The recommended reflow profile using Sn/Ag/Cu solder is shown in the following. Recommended reflow peak temperature is 245C while the part can withstand peak temperature of 260C maximum for 10 seconds. This profile should be used only as a guideline. Many other factors influence the success of SMT reflow soldering. Since your production environment may differ, please thoroughly review these guidelines with your process engineers. Figure 36. Soldering information The SRPE-30E1A0 modules have a MSL rating of 3. The SRPE-30E1A0 modules are designed to be compatible with J-STD-033 Rev: A (Handling, Packing, Shipping and Use of Moisture /Reflow Sensitive surface Mount devices). Moisture barrier bags (MBB) with desiccant are applied. The recommended storage environment and handling procedure is detailed in J-STD-033. This component has been designed, handled, and packaged ready for Pb-free reflow soldering. If the assembly shop follows J-STD033 guidelines, no pre-bake of this component is required before being reflowed to a PCB. However, if the J-STD-033 guidelines are not followed by the assembler, Bel recommends that the modules should be pre-baked @ 120~125C for a minimum of 4 hours (preferably 24 hours) before reflow soldering. tech.support@psbel.com SRPE-30E1A0 17 Figure 37.
