مقدمة المنتج:CDBHM2100L-HF مقدمة المنتج

The Comchip Technology CDBHM2100L-HF is a single-phase surface mount bridge rectifier in a compact MINI2DIP package, designed for AC-to-DC power conversion in space-constrained applications. Rated at 100V maximum repetitive reverse voltage and 1A average forward current, this bridge rectifier provides full-wave rectification using four internally connected silicon diodes in a Graetz bridge configuration. The low 1.0V peak forward voltage per element minimizes power dissipation and improves conversion efficiency. The HF suffix indicates halogen-free and lead-free green packaging that meets IEC 61249-2-21 and RoHS requirements. The MINI2DIP package offers a significantly smaller footprint than traditional DIP bridge rectifiers.

مبدأ العمل:CDBHM2100L-HF مبدأ العمل

The CDBHM2100L-HF bridge rectifier converts single-phase AC input to pulsating DC output using four diodes arranged in a Graetz bridge configuration. During the positive half-cycle of the AC input, two diagonally opposite diodes conduct, allowing current to flow through the load in one direction. During the negative half-cycle, the other two diodes conduct, maintaining the same current direction through the load. This full-wave rectification doubles the ripple frequency compared to half-wave rectification, simplifying downstream filtering. Each diode in the bridge drops approximately 1.0V when conducting, resulting in a total forward voltage drop of approximately 2.0V (two diodes in series per half-cycle). The 30A peak surge current rating accommodates initial power-on capacitor charging transients.
