The SDS32R4K is a slim, compact DC solid-state relay designed for printed circuit board applications with a maximum output current of 4 A at 32 Vdc and a control input range of 18–32 Vdc. It features an integrated voltage clamp and high surge handling capabilities, with a maximum non-repetitive surge current rating of 9 A and an on-state voltage drop of 0.24 V at 2 A. The relay exhibits fast switching performance with a turn-on time of 50 µs and turn-off time of 600 µs, an off-state leakage current of 1 mA, and an input-output isolation of 2500 Vrms. Operating across a temperature range of -20 °C to +80 °C with a compact form factor and 0.28 oz weight, this relay is ideal for industrial control, power distribution, and load switching applications requiring reliable DC switching in space-constrained environments.
