www.irf.com 3 RDHA710SE10A2FK notes for maximum ratings and electrical characteristic tables specification is guaranteed by design rise and fall times are controlled internally inputs protected for v in < 1.0v and v in > 7.5v optically coupled solid state relays (ssrs) have relatively slow turn on and turn off times. care must be taken to insure that transient currents do not cause violation of soa. if transient conditions are present, ir recommends a complete simulation to be performed by the end user to insure compliance with soa requirements as specified in the irhnj57130 data sheet while the ssr design meets the design requirements specified in mil-prf-38534, the end user is responsible for product derating, as required for the application reference figures 3 & 4 for switching test circuits and wave form total dose irradiation with input bias. 10ma i dd applied and v ds = 0 during irradiation total dose irradiation with output bias. 80 volts v ds applied and i dd = 0 during irradiation international rectifier does not currently have a dscc certified radiation hardness assurance program post total dose irradiation , , electrical characteristics per channel @ 25c (unless otherwise specified) parameter group a test conditions symbol min. typ. max. units subgroups output on-resistance 1 v in = 3.3v, v dd = 5.0v, i o = 10a r ds(on) -- 0.070 0.100 ? input supply current 1 v dd = 5.0v, i o = 10a i dd -- 18 25 ma output leakage current 1 v in = 0.1v, v s = 100v i o -- -- 25 input buffer current 1 v in = 3.3v i in -- -- 1.0 v in =3.3v, v dd =5.0v, v s =30v rc = 7.0 ? / 100 ? /100 f, pw = 50ms v in =3.3v, v dd =5.0v, v s =30v rc = 7.0 ? /100 ? /100 f, pw = 50ms rise time 1--0.25 a 1 turn-on delay 1 turn-off delay ms -- 0.18 0.50 0.45 fall time t f -- 1.50 1 t on 1.80 t off -- t r 0.75 0.40
