Reliable 1200 V Bolt‑Mount Rectifier Diode — 25 A to 85 A models Why choose this rectifier diode Delivers dependable rectification at a 1200 V rating for demanding electrical applications. High surge-current capability prevents failures during inrush or transient events, keeping equipment running under heavy loads. Available in multiple current ratings (25 A to 85 A), so you can match performance to your application without over‑specifying. Key features and benefits Models: 25 A, 35 A, 45 A, 55 A, 65 A, 75 A, 85 A (range covers common industrial needs). Rated voltage: 1200 V for robust high-voltage operation. High transient and surge current handling for reliable performance in equipment with large startup or pulse currents. Bolt-mount (bolt holder) package for secure electrical and mechanical connection, simplified installation, and easier maintenance. Consistent, predictable diode behavior that reduces downtime and maintenance cost in continuous-operation environments. Compatibility and performance Function: rectification of AC to DC in power conversion and charging systems. Compatible with standard bolt-mount assemblies used in power supplies, welders, chargers, converters, and machine tool controls. Choice of current ratings lets you balance thermal management and efficiency for your specific design. Typical use scenarios Industrial power supply: As the main rectifier in a DC bus, the diode handles high steady currents and occasional surges without compromising uptime. Welding equipment: Absorbs welding-start transients and inrush, providing durable rectification for stable welding arcs and long service life. Charging and conversion systems: Used in battery chargers and DC converters where 1200 V blocking capability and high surge tolerance are required. Installation and maintenance notes Bolt-holder mounting simplifies attachment to heatsinks or chassis for effective thermal dissipation (select appropriate heatsinking for the selected current model). Accessible mounting style reduces service time during replacement or inspection. Choose this rectifier diode when you need a proven, bolt-mount solution with a 1200 V rating, robust surge capability, and a range of current options from 25 A to 85 A for industrial and power‑electronics applications.
