Celduc Relais Solid State Relays SKL10521

The SKL10521 is a solid state relay for printed circuit board mounting, designed for AC output control with a 50A thyristor rating and a 230VAC load voltage capacity. It features thyristor and DCB (Direct Copper Bonding) technology, with an input control range of 3 to 14VDC and a control current of 2.8 to 19.5mA at 12V. The relay supports a maximum non-repetitive surge current of 700A for 10ms and an I2t value of up to 2450 A²s for short-circuit protection. It has an input-output isolation of 4000 VRMS and operates within a temperature range of -40°C to +80°C. The device requires an external heatsink and a 14mm varistor across the output. It is not suitable for reflow soldering and must be wave soldered at no more than 260°C for 10 seconds. Compliance includes EN60947-4-x, EN61810-xxx, and UL File E69913.
