Brass-Terminal 1600V Solar Rectifier

This 1600V-rated common cathode rectifier module handles up to 200A forward current and is built for photovoltaic DC system durability. Housing material is ABS; current-carrying terminals are solid brass — selected for superior thermal and electrical conductivity, corrosion resistance, and mechanical strength. Electrical specs include 12mA and 20mA leakage current values, 2500V AC insulation rating, and 150°C maximum junction temperature. Its 3-terminal layout supports straightforward integration into photovoltaic combiner boxes, DC distribution cabinets, and inverter DC input stages. Internal construction uses precision welding instead of solder or crimping — delivering lower parasitic inductance, higher mechanical integrity, and improved resistance to thermal fatigue. This results in more predictable forward voltage behaviour and extended service life under real-world PV duty cycles involving frequent partial-load operation and rapid ambient temperature shifts. Heat dissipation relies on direct conduction through brass terminals into the heatsink or mounting plate — eliminating reliance on air convection or external heatsinks in many applications. This makes it especially suitable for compact, sealed enclosures typical in UK residential and commercial solar installations.
