BU1206-M3/51

Bridge Rectifier Overview

The BU1206-M3/51 is a single-phase bridge rectifier from Vishay General Semiconductor, utilizing enhanced isoCink+ technology. It features a maximum repetitive peak reverse voltage of 600 V and an average rectified forward current rating of 12 A at a case temperature of 85 °C. The device exhibits a typical junction capacitance of 50 pF per diode and a maximum non-repetitive peak forward surge current of 150 A. Operating within a junction and storage temperature range of -55 to +150 °C, it incorporates glass passivated chip junctions for superior thermal conductivity. The component is housed in a thin single-in-line BU package with matte tin plated leads.

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging configuration. The M3 designation indicates halogen-free, RoHS-compliant commercial grade material categorization. Confirm that the /51 suffix corresponds to paper tray delivery mode rather than tube packaging. Ensure technical parameters align with application requirements before procurement.

Bridge Rectifier Selection Notes

Select this component based on its 600 V reverse voltage capability and 12 A average forward current rating. Consider the thermal resistance characteristics when designing heatsinking solutions for high ambient temperatures. Verify compatibility with free air derating curves if operating without external heatsinks. Ensure the BU package dimensions fit the intended PCB layout constraints.

Bridge Rectifier Part Context

This part belongs to the BU1206, BU1208, and BU1210 series of enhanced isoCink+ bridge rectifiers. The series offers varying peak reverse voltage ratings while maintaining consistent current handling capabilities.
