LESDA6V1W5T1G

LESHAN RADIO COMPANY, LTD. LESDA6V1W5T1G Quad Array for ESD Trotection General Description 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. Features 4 Unidirectional Transil functions Breakdown voltage: VBR = 6.1 V min. and 25 V min. Low leakage current: < 1 mA Very small PCB area < 4.2 mm2 typically High ESD protection level: up to 25 kV High integration Applications Computers Printers Communication systems Cellular phones handsets and accessories Wireline and wireless telephone sets Set top boxes Complies with the following standards IEC61000-4-2 Level 4 16 kV (air discharge) 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 Parameter Value Units PPP TL Tstg Top Peak Pulse Power (tp = 8/20μs) LESDA6V1W5T1G 150 260 -40 to +125 -40 to +125 W °C °C °C Maximum lead temperature for soldering during 10s Storage Temperature Range Operating Temperature Range 1 LESHAN RADIO COMPANY, LTD.
