2 www.irf.com RDHA701CD10A2NX notes for maximum ratings and electrical characteristic tables specification is guaranteed by design. rise and fall times are controlled internally. 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 a 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 irhq57110 data sheet. while the ssr design meets the design requirements specified in mil-prf-38534, the end user is responsible for product derating, as applicable for the application. reference fig. 2 for switching test circuit and fig. 3 for switching test wave form. turn-on time (ton) includes the turn-on delay and rise time; turn-off time (toff) includes the turn-off delay and fall time international rectifier does not currently have a dla certified radiation hardness assurance plan. electrical characteristics per channel @ -55c t c +125c (unless otherwise specified) parameter group a test conditions symbol min. typ. max. units sub g roups 1-- 0.25 0.40 2 -- 0.39 0.80 1----10 2----25 input forward voltage 1, 2, 3 i f = 10ma v f 1.0 -- 1.85 v input-to-output leakage current i i-o channel-to-channel leakage current 1 v i-o = 1000vdc, dwell = 5s i ch-ch -- -- 1.0 a pin-to-case leakage current i case i f = 0 to 10ma, v bus = 28v, i o = 1.0a, duty cycle 1.0% i f = 10ma to 0, v bus = 28v, i o = 1.0a, duty cycle 1.0% output capacitance i f = 0, v=+25v, f=1mhz,t c =25c c oss -- 110 -- pf thermal resistance per channel r thjc -- -- 15 c/w mtbf mil-hdbk-217f, sf@ t c =25c 22.7 -- -- mhrs 9, 10, 11 a i o -- -- 2.0 ms 4.0 ? -- -- turn-off time output on-resistance i f = 10ma, i o = 1.0a r ds(on) turn-on time 9, 10, 11 t on t off i f = 0, v out = 100v output leakage current
