Infineon BAS4002A: High-Performance Bridge Rectifier for Compact Power Designs

In the relentless pursuit of miniaturization and efficiency in modern electronics, the selection of core components like bridge rectifiers is critical. The Infineon BAS4002A stands out as a premier solution, engineered specifically to meet the demanding requirements of compact and efficient power supply designs. This device encapsulates advanced semiconductor technology to deliver superior performance in a minimal footprint.

At the heart of the BAS4002A is its use of high-quality Schottky diode technology. Unlike conventional PN-junction rectifiers, Schottky diodes have a lower forward voltage drop (V_F), typically around 0.36V at a forward current of 0.5A. This key characteristic directly translates to significantly reduced power losses and lower heat generation during operation. For space-constrained applications where thermal management is a challenge, this efficiency is a major advantage, enabling cooler running and more reliable end products.

The component is housed in an ultra-compact DSO-8 surface-mount (SMD) package. This miniature form factor is ideal for high-density PCB designs, allowing engineers to save valuable board real estate without compromising on performance. Despite its small size, the BAS4002A is robust, offering a high surge current capability of I_FSM = 30A and a maximum average forward rectified current of I_F(AV) = 0.8A. Its high operating junction temperature of up to 125 °C further ensures reliability under strenuous conditions.

Furthermore, the bridge rectifier is designed for a reverse voltage of 200 V, making it perfectly suited for a wide array of consumer and industrial applications, including AC/DC adapters, low-power switch-mode power supplies (SMPS), battery chargers, and auxiliary power sources for home appliances.

ICGOOODFIND: The Infineon BAS4002A is a high-efficiency, miniature bridge rectifier that sets a new benchmark for compact power design. Its exceptional combination of low forward voltage, a robust SMD package, and high thermal performance makes it an indispensable component for engineers aiming to optimize both size and efficiency in their power conversion stages.
