| ESDAXXXWX TRANSILTM array for data protection Main applications Where transient overvoltage protection in ESD sensitive equipment is required, such as : Computers Printers Communication systems Cellular phones handsets and accessories Wireline and wireless telephone sets Set top boxes SOT323-3L Order codes SOT323-5L SOT323-6L Part Numbers ESDA6V1W5 ESDA6V1-5W6 Marking E61 E62 E25 E25 Features ESDA25W ESDA25W5 2 up to 5 Unidirectional Transil functions Breakdown voltage: VBR = 6.1 V min. and 25 V min. Low leakage current: < 1 A Very small PCB area < 4.2 mm2 typically ESDA25W Functional diagram 1 3 Description The ESDAXXXWX are monolithic suppressors designed to protect components connected to data and transmission lines against ESD. These devices clamp the voltage just above the logic level supply for positive transients, and to a diode drop below ground for negative transients. 2 ESDA6V1W5/ESDA25W5 Functional diagram 1 2 3 4 5 Benefits High ESD protection level: up to 25 kV High integration Complies with the following standards IEC61000-4-2 Level 4 15 kV (air discharge) 8 kV(contact discharge) ESDA6V1-5W6 Functional diagram 1 2 3 6 5 4 MIL STD 883E - Method 3015-7 Class 3 25 kV HBM (Human Body Model) August 2005 Rev 2 1/11 www.st.com 11 1 Characteristics ESDAXXXWX 1 Characteristics Table 1.
