Bridge Rectifier Procurement Notes
Verify the specific ordering suffix to confirm the delivery mode and packaging format. The E3 suffix indicates RoHS compliance and halogen-free status for commercial grade applications. Confirm that the required quantity aligns with the standard tube base quantity of 20 units associated with the /45 designation.
Bridge Rectifier Selection Notes
Select this component when a 600 V peak reverse voltage rating is required for single-phase bridge rectification. Ensure the thermal design accommodates the specified derating curves for average forward current based on the intended mounting method, whether heatsink-mounted or PCB-mounted without additional cooling.
Bridge Rectifier Part Context
This part belongs to the GBU8 series of glass passivated single-phase bridge rectifiers. The series includes variants with different voltage ratings ranging from 50 V to 1000 V, sharing identical physical dimensions and electrical characteristics except for the maximum repetitive peak reverse voltage and related ratings.
