: p- `# K0 K! a* C4 T
Inrush current, input surge current, or switch-on surge is the maximal instantaneous input current drawn by an electrical device when first turned on.

9 ]/ \# G7 u1 n; ^* TThe main cause is the current was used to charge into capacitors.2 s+ B' W7 W1 Y1 A- M2 L# }
To reduce this problem, I often don't use a TVS. Instead I always use a inrush current limit circuit like this:
8 m) x0 E4 D2 H1 H+ D5 d3 b% g
0 ~: {$ @( c9 z# r3 V% n7 V
$ t+ [+ I& Q v6 a# Q![]()
4 j! G6 d- u9 g' H$ w, B7 y2 R* U! Z# \& S4 B& `0 x
