ESDAL 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. Unidirectional device It can also be used as bidirectional suppressor by Low leakage current (IR max. < 20 A at connecting only pin 1 and 2. V ) BR Figure 1: Functional diagram 300 W peak pulse power (8/20 s) Benefits High ESD protection level: up to 30 kV 1 High integration Suitable for high density boards 3 Complies with the following standards IEC 61000-4-2 (exceeds level 4) : 2 30 kV (air discharge) 30 kV (contact discharge) July 2017 DocID7058 Rev 5 1/11 www.st.com This is information on a product in full production.
