WOST04 Datasheet, PDF (1/3 Pages) Weitron Technology – Surface Mount TVS Diode Array for ESD Protection

Surface Mount TVS Diode Array
for ESD Protection
P b Lead(Pb)-Free
Description:
* The WOSTxx is a transient voltage suppressor designed to
protect components which are connected to data and
transmission lines against ESD. It clamps the voltage just
above the logic level supply for positive transients, and to
a diode drop below ground for negative transients.
Features:
* Unidirectional Transil functions
* Low leakage current: I_R max< 20 μA at V_RM
* 300W peak pulse power(8/20μs)
* Transient protection for data lines as per
IEC61000-4-2(ESD) 15KV(air) 8KV(contact)
IEC61000-4-5(Lightning) see I_PPM below
Mechanical Data:
* Case : Molded Epoxy
* Marking : Marking Code
* Weight : 0.008 grams(approx)
