The PC792A is an automotive relay with a 40 A continuous current rating, designed for switching applications up to 75 VDC. It features a SPST NO (1A) contact form, a 48 VDC coil requiring 1.9 W power, and includes a parallel diode for suppression. The part is mounted in a weatherproof case with a metal bracket (C3), sealed for protection, and has tin-plated terminals. Dimensions are 26.0 mm × 26.0 mm × 17.9 mm, with a weight of 31.0 g. It operates from -40°C to 125°C and meets mechanical and electrical life ratings of 10⁷ and 10⁵ operations respectively. The contact material is AgSnO₂, with an initial contact resistance of 30 mΩ max. The relay complies with terminal strength standards of 8 N for quick connect and 4 N for PCB pins, and withstands 500 Vrms dielectric strength between contacts and 750 Vrms between coil and contacts.
