ESDA5V3L

® ESDAxxL DUAL TRANSIL ARRAY FOR ESD PROTECTION Application Specific Discretes A.S.D. APPLICATIONS Where transient overvoltage protection in ESD sensitive equipment is required, such as : - COMPUTERS - PRINTERS - COMMUNICATION SYSTEMS It is particulary recommended for the RS232 I/O port protection where the line interface withstands only with 2kV ESD surges. FEATURES n n SOT23 n 2 UNIDIRECTIONAL TRANSIL FUNCTIONS. LOW LEAKAGE CURRENT : IR max. < 20µA at VBR. 300 W PEAK PULSE POWER (8/20µs) DESCRIPTION The ESDAxxL is a dual monolithic voltage suppressor designed to protect components which are connected to data and transmission lines against ESD. It clamps the voltage just above the logic level supply for positive transients, and to a diode drop below ground for negative transients. It can also work as bidirectionnal suppressor by connecting only pin1 and 2. FUNCTIONAL DIAGRAM BENEFITS High ESD protection level : up to 25 kV. High integration. Suitable for high density boards. COMPLIES WITH THE FOLLOWING STANDARDS : IEC61000-4-2 level 4 MIL STD 883C-Method 3015-6 : class 3.
