ESDALY Automotive dual Transil array for ESD protection Datasheet - production data Applications Where transient overvoltage protection in ESD sensitive equipment is required, such as: Entertainment Signal communications Connectivity Comfort and convenience Description SOT23-3L This device is a diode array designed to protect 1 line or 2 lines against ESD transients. The device is ideal for applications where both reduced line capacitance and board space saving Features are required AEC-Q101 qualified It can also be used as bidirectional suppressor by Dual unidirectional Transil functions connecting only pin 1 and 2. Low leakage current: IR max. < 20 A at VBR Figure 1: Functional diagram 300 W peak pulse power (8/20 s) Benefits High ESD protection level: up to 25 kV 1 High integration Suitable for high density boards AEC-Q101 qualified 3 Complies with the following standards ISO 10605: C = 330 pF, R = 330 2 30 kV (air discharge) 30 kV (contact discharge) ISO 7637-3 fast transient Pulse a: V = -150 V S Pulse b: V = +100 V S ISO 7637-3 slow transient Positive pulse: VS = +85 V Negative pulse : VS = -85 V July 2017 DocID022075 Rev 2 1/12 www.st.com This is information on a product in full production.
