LESDA6V1W6T1G

LESHAN RADIO COMPANY, LTD. LESDA6V1W6T1G S-LESDA6V1W6T1G Transil array for data protection General Description Features The LESDA6V1W6T1G 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 Computers z Printers z Communication systems z Cellular phones handsets and accessories z Wireline and wireless telephone sets z Set top boxes z z z z z z z z z 5 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 Device marking:WF S- Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC-Q101 Qualified and PPAP Capable.
