SRDA70-4

The SRDA70-4 railclamps are rated diode arrays designed to protect high speed data interfaces.The SR series has been specifically designed to protect sensitive components which are connected to data and transmission lines from overvoltage caused by ESD (electrostatic discharge),EFT(eletrical fast transients),and lightning.

Features of the SRDA70-4 are:(1)transient protection for high-speed data lines;(2)array of surge rated diodes with internal TVS diode;(3)protects four I/O lines;(4)low capacitance for high-speed interfaces;(5)high surge capability;(6)low forward voltage characteristics;(7)solid-state techology.Applications of the SRDA70-4 are:(1)latch-up protection;(2)microcontroller input protection;(3)token ring;(4)I2C bus protection;(5)video line protection;(6)set top box I/O;(7)lan/wan equipment.

The absolute maximum ratings of the SRDA70-4 can be summarized as:(1):the rating is peak pulse current,the symbol is IPP,the value is 24,the unit is A;(2):the rating is rectifier repetitive peak reverse voltage,the symbol is VRRM,the value is 70,the unit is V;(3):the rating is thermal resistance,junction to ambient,the symbol is JA,the value is 163,the unit is /W;(4):the rating is thermal resistance,junction to case,the symbol is JC,the value is 38.8,the unit is /W;(5):the rating is lead soldering temperature,the symbol is TL,the value is 260(10 sec),the unit is ;(6):the rating is operating temperature,the symbol is Tj,the value is -55 to +125,the unit is ;(7):the rating is storage temperature,the symbol is Tstg,the value is -55 to +150,the unit is .
