SR12
500 WATT loW cAPAciTAnce STeeRing diode/TVS ARRAy
deScRiPTion
The SR12 is a low capacitance steering diode TVS array, designed to protect two I/O lines from the effects of Electro-
static Discharge (ESD) and Electrical Fast Transients (EFT). The SR12 provides ESD protection and has a peak pulse
power rating of 500 Watts for an 8/20s waveshape.
The low capacitance of the steering diode allows the designer to protect high speed data applications. The small
SOT-143 package, with four leads reduces the internal lead inductance for low overshoot voltage during fast front time
transient events, such as ESD. The SR12 meets the IEC 61000-4-2 and IEC 61000-4-4 requirements.
