Micro Commercial Components (MCC) has introduced the PB-A Series of high-voltage bridge rectifiers (PBA2510 and PBA3516), designed to address two critical challenges in demanding power electronics: insulation performance in contaminated or humid environments, and effective thermal management for long-term system reliability.
The PB-A Series features a specially engineered package that provides creepage distances greater than 4 mm, enhancing surface insulation and reducing the risk of tracking or leakage under harsh environmental conditions. These characteristics make the devices ideal for industrial and infrastructure systems where safety margins and insulation integrity are essential.
Each device uses glass-passivated chip junctions, which help stabilize reverse characteristics and minimize leakage over the product’s lifespan. Additionally, optimized internal thermal conductivity facilitates efficient heat transfer from the die to the case. This results in lower junction temperatures, supporting smaller heatsink designs, more compact system layouts, or increased power output without compromising durability.
Available in 25 A and 35 A variants, with voltage ratings of 1000 V and 1600 V, the PB-A Series offers strong surge current capabilities. These devices are built to handle high inrush currents and AC line transients while maintaining dependable blocking performance. Their low thermal resistance and forward voltage drop contribute to system efficiency, while the mechanically robust and easy-to-mount PB-A package simplifies integration.
The PB-A Series is ideally suited for AC front-end applications in switched-mode power supplies (SMPS), uninterruptible power supplies (UPS), battery chargers, and various industrial and infrastructure power systems where durability, thermal efficiency, and insulation reliability are critical.
