Specifications are subject to change without notice (09.10.2020) 5 A pplications Therm al characteristics The thermal design of Solid State Relays is very im por - tant. It is essential that the user makes sure that cooling is ad - e quate and that the maximum junction tem per a ture of the re - lay is not ex ceed ed. This relay is designed for use in applications in which it is exposed to high surge con di - tions. Care must be taken to ensure proper heatsinking when the relay is to be used at high sustained currents. Ade- quate electrical con nec tion between relay terminals and cable must be ensured. Heat flow Heatsink temperature Rth j-c Rth c-s Rth s-a Junction temperature Case temperature Ambient temperature Thermal resistance: Rth j-c = junction to case Direct bonding In the design of the output power sem i con duc tor di rect bonding of the copper layer and the ceramic substrate has been applied. This is to en - sure uninhibited heat transfer and high thermal fa tigue strength. The relay has been designed for applications requiring lar- ge numbers of load cycles. Power dissipation The power dissipation for in - ter mit tent use is calculated ac- cording to the following for - mu la: ton toff OFF ON Irms = ION 2 x t ON tON + t OFF Ex: RA 24 50 -D 06: Load current = 45 A tON = 30 s t OFF = 15 s Irms = 45 2 x 30 30 + 15 The rms current will be 36.7 A. If the heatsink is placed in a small closed room, control panel or the like, the power dissipation can cause the ambient temperature to rise. The heatsink is to be cal- culated on the basis of the ambient temperature and the increase in temperature.
