YBS3004G

Overview

The YBS3004G is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation. It features a glass passivated junction and is housed in the YBS-4 surface-mount package. The device supports an average forward current of 3 A with peak reverse voltage ratings ranging from 400 V to 1000 V across the series. Key electrical parameters include a maximum non-repetitive peak surge current of 220 A, a forward voltage of 0.93 V at rated current, and a leakage current of 5 µA at maximum reverse voltage. Operating temperatures range from -55°C to +150°C.

Feature Summary

• Glass passivated junctions provide mechanical strength and protection against external stress.
• Surface-mount YBS-4 package design facilitates automated assembly processes.
• High surge current capability ensures robustness during transient power events.

Applications

• General-purpose AC to DC conversion circuits
• Power supply input stages for consumer electronics
• Adapter and charger front-end rectification

Procurement Notes

Verify the specific voltage sub-rating (e.g., 400V, 600V, 800V, or 1000V) required for the application, as the YBS3004G prefix denotes the 3A/4-pin form factor within the broader YBS300xG family. Confirm RoHS compliance status and packaging format (cut tape or reel) directly with the manufacturer or authorized distributors prior to ordering.

Selection Notes

Select this component when a compact surface-mount solution is needed for 3A rectification. Ensure the circuit's peak inverse voltage does not exceed the specific rating of the chosen suffix variant. Verify that the PCB footprint matches the YBS-4 package dimensions of 7.4 mm by 6.7 mm.

Part Context

This part belongs to the YBS300G series of glass passivated bridge rectifiers. The series offers various voltage ratings including YBS3004G (400V), YBS3006G (800V), and YBS3007G (1000V). All variants share the same 3A current rating and physical package, differing primarily in their peak reverse voltage capabilities.

Replacement Considerations

Direct substitutes within the same package and rating include YBS3006G and YBS3007G if higher voltage tolerance is acceptable. Other manufacturers offering equivalent 3A SMD bridge rectifiers in similar footprints may be considered after verifying thermal and electrical parameter alignment.
