radiation hardended, 100v, single 10a, solid state relay www.irf.com 1 05/18/12 description features: total dose capability to 100krad (si) optically coupled 1000v dc input-to-output and pin-to-case isolation hermetically sealed ceramic package the rdha710fr10a1nx is a radiation hardened solid state relay in a hermatic package. it is configured as a single pole single throw (spst) normally open relay. this device is characterized for 100krad (si) total ionizing dose. the output mosfet utilizes international rectifier?s r6 technology. rdha710fr10a1nk for notes, please refer to page 2 absolute maximum ratin g s @ tj = 25c (unless otherwise specified) parameter s y mbol value units output withstand voltage v o (off) 100 v output current i o 10 peak output current i o pk 20 input forward current i f 40 peak input forward current (t 1.0ms) i f pk 100 peak input reverse voltage (t 1.0ms) v r 5.0 v power dissipation p diss 4.0 w operating temperature range t j -55 to +125 storage temperature range t s -65 to +150 c lead temperature t l 300 weight 2.5 (typ) g a ma 22 pin flat pack product summary part number voltage current configuration rad level rdha710fr10a1nk 100v 10a single dc 100k pd-97579a
2 www.irf.com rdha710fr10a1nk notes for maximum ratings and electrical 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 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 irhna67160 data sheet. 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. 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. electrical characteristics @ -55c t c +125c (unless otherwise specified) parameter group a test conditions s y mbol min. t y p. max. units sub g roups 1-- 0.012 0.020 2 -- 0.018 0.040 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 l-o pin-to-case leakage current i case i f = 0 to 10ma, v bus = 28v, i o = 2.5a, dut y c y cle 1.0% i f = 0 to 10ma, v bus = 28v, i o = 2.5a, dut y c y cle 1.0% output capacitance i f = 0, v =+25v, f =1mhz, t c = 25c c oss -- 1600 -- pf thermal resistance r thjc -- -- 5.0 c/w mtbf mil-hdbk-217f, tc = 25c 6.5 -- -- mhrs i f = 0, v out = 100v i o a -- 1.0 9, 10, 11 t on -- a ms ? -- 8.0 -- -- 0.3 -- turn-off time output on-resistance i f = 10ma, i o = 4.0a r ds(on) t off turn-on time 9, 10, 11 1 vi-o = 1000vdc, dwell = 5s output leakage current
