MB6S-G

Bridge Rectifier Overview

The MB6S-G is a single-phase, surface-mount glass passivated bridge rectifier manufactured by Comchip Technology. It features a molded plastic case with solder-plated leads designed for printed circuit board mounting. The device supports a maximum average forward recurrent current of 0.8A and offers a maximum recurrent peak reverse voltage of 600V. Key electrical characteristics include a maximum instantaneous forward voltage of 1.0V at 0.4A and a peak forward surge current rating of 50A under JEDEC testing conditions. The component operates within a temperature range of -55°C to +150°C.

Bridge Rectifier Feature Summary

• Glass passivated die construction ensures stable performance and low leakage current.
• Surface mount package design facilitates automated assembly and space-saving on PCBs.
• High surge overload capability rated at 50A for single half-sine wave pulses.

Bridge Rectifier Applications

• General purpose AC to DC conversion in compact electronic devices.
• Power supply circuits requiring surface mount bridge rectification.
• Adapters and chargers utilizing resistive or inductive loads.

Bridge Rectifier Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to confirm exact electrical ratings and packaging specifications. Ensure that ordering requirements align with the standard reel quantity of 2,500 pieces per 13-inch reel as defined in the datasheet. Cross-reference mechanical dimensions with PCB layout guidelines to guarantee proper footprint compatibility during procurement planning.

Bridge Rectifier Selection Notes

Select this component when a 600V reverse voltage rating and 0.8A continuous current capacity are required for surface mount applications. Consider the thermal resistance values provided for aluminum substrate versus glass epoxy PCB mounting when designing heat dissipation strategies. Verify that the operating environment remains within the specified -55°C to +150°C junction temperature range for reliable operation.

Bridge Rectifier Part Context

This component belongs to the MB2S-G through MB10S-G series of glass passivated bridge rectifiers from Comchip Technology. The series provides various reverse voltage options ranging from 200V to 1000V while maintaining a consistent 0.8A forward current rating. The MB6S-G specifically addresses applications needing 600V blocking capability in a standardized SOP-4 surface mount package.

Bridge Rectifier Replacement Considerations

Compatible substitutes within the same series include MB4S-G (400V) and MB8S-G (800V), provided the voltage rating meets the circuit requirements. Other manufacturers offering similar 0.8A SMD bridge rectifiers may be considered if mechanical dimensions and electrical parameters match the datasheet specifications exactly.

Bridge Rectifier FAQ

What is the maximum non-repetitive peak forward surge current?

The MB6S-G can withstand a peak forward surge current of 50A for an 8.3ms single half-sine wave pulse superimposed on rated load, tested according to JEDEC methods.

How does the mounting substrate affect thermal performance?

Thermal resistance varies based on the PCB material; it is rated at 70°C/W on an aluminum substrate with a 0.8x0.8 inch area, whereas different values apply for glass epoxy PCBs mounted on specific solder pads.

Is derating required for capacitive loads?

Yes, when used with capacitive loads, the forward current must be derated by 20% compared to the rated maximum average forward recurrent current of 0.8A.
