LESHAN RADIO COMPANY, LTD. LESDA6V1W5T1G Quad Array for ESD Trotection General Description Features The LESDA6V1W5T1G is a monolithic suppressor designed to protect components connected to data and transmission lines against ESD. The device clamp the voltage just above the logic level supply for positive transients, and to a diode drop below ground for negative transients. Applications z 4 Unidirectional Transil functions z Breakdown voltage: z VBR = 6.1 V min. and 25 V min. z Low leakage current: < 1 mA z Very small PCB area < 4.2 mm2 typically z High ESD protection level: up to 25 kV z High integration Complies with the following standards z Computers IEC61000-4-2 z Printers Level 4 16 kV (air discharge) z Communication systems z Cellular phones handsets and accessories z Wireline and wireless telephone sets z Set top boxes 9 kV(contact discharge) MIL STD 883E - Method 3015-7 Class 3 25 kV HBM (Human Body Model) Functional diagram LESDA6V1W5T1G Absolute Ratings (Tamb=25°C ) Symbol PPP Parameter Peak Pulse Power (tp = 8/20μs) LESDA6V1W5T1G Value Units 150 W TL Maximum lead temperature for soldering during 10s 260 °C Tstg Storage Temperature Range -40 to +125 °C Top Operating Temperature Range -40 to +125 °C 1 LESHAN RADIO COMPANY, LTD.
