The peak pulse current (IPP), is defined as the maximum surge current that can be shunted before the diode itself will overheat and fail. Recall that a surge event can be defined in terms of a maximum current – IPP is a critical value as it determines whether a given diode can absorb that maximum current without seeing any damage.

Part one discusses the important considerations when selecting the right battery for a consumer application. These include rechargeability, energy density, power density, shelf life, safety, form factor, cost, and flexibility. Part two discusses how chemistry affects important battery metrics, and therefore battery selection.
Part 1: Important Battery Metrics The one thing to remember about battery selection is that there is no such thing as a perfect battery that works for every application. Selecting the right battery for your application is about identifying the most important battery metrics and trading these off against others.
