ESDA37W STMicroelectronics

ESDA37W Dual Transil array for ESD protection Datasheet - production data Applications Where transient overvoltage protection in ESD sensitive equipment is required, such as: Entertainment 3 Signal communications 2 Connectivity Comfort and convenience 1 SOT323-3L Description 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 a bidirectional suppressor by Low leakage current (IR max. < 1 A at VRM) connecting only pin 1 and 2. 300 W peak pulse power (8/20 s) Figure 1: Functional diagram Benefits High ESD protection level: up to 30 kV High integration 1 Suitable for high density boards Complies with the following 3 standards IEC 61000-4-2 (exceeds level 4) : 30 kV (air discharge) 2 30 kV (contact discharge) October 2017 DocID031000 Rev 1 1/10 www.st.com This is information on a product in full production.
