www.irf.com 3 RDHA720SF06A1NK notes for maximum rating, electrical and general characteristic tables specification is guaranteed by design 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 ensure compliance with soa requirements as specified in the irhn7054 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 circuit and wave form total dose irradiation with input bias 20ma i dd applied and v ds = 0 during irradiation total dose irradiation with output bias 48 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 @ 25c (unless otherwise specified) , , parameter group a test conditions symbol min. typ. max. units sub g roups output on-resistance 1 i dd = 20ma, i o = 20a r ds(on) -- 0.03 0.040 ? output leakage current 1 i dd 0.5ma, v out = 60v i o -- -- 25 a i dd = 20ma, v s = 40v, i o = 20a pw = 4.0ms, d 1% v s = 40v, i o = 20a pw = 4.0ms, d 1% i dd = 20ma, v s = 40v, i o = 20a pw = 4.0ms, d 1% v s = 40v, i o = 20a pw = 4.0ms, d 1% rise time 1--1.1 1 turn-on delay 1 turn-off delay ms -- 0.8 0.05 1.6 fall time t f -- 0.06 1 t on 0.15 t off -- t r 0.13 2.2
