GBJ3508-BP

Overview

The GBJ3508-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It features an average forward current rating of 35 A and a maximum repetitive peak reverse voltage of 800 V. The device utilizes glass passivation for junction protection and is housed in a GBJ plastic package designed for through-hole mounting. Key electrical characteristics include a forward voltage drop of 1.1 V at 35 A and a maximum reverse leakage current of 5 µA at 800 V. The component operates within a junction temperature range of -55°C to 150°C.

Feature Summary

• Glass passivated junctions provide reliable operation under high-temperature conditions.
• High surge current capability supports transient load handling.
• Low forward voltage drop contributes to improved system efficiency.

Applications

• AC-to-DC power supply circuits
• Battery charging systems
• General-purpose rectification in industrial equipment

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm compliance with RoHS directives, as the "BP" suffix typically indicates lead-free and halogen-free status. Ensure that the procurement specifications align with the required thermal management capabilities for the intended operating environment. Cross-reference the datasheet revision date to confirm the accuracy of the electrical parameters provided.

Selection Notes

Select this component when a 35 A current rating and 800 V blocking voltage are required for through-hole assembly. Compare the forward voltage drop and thermal resistance values against alternative packages such as KBPC or MB series if space constraints differ. Confirm that the PCB layout accommodates the specific pin spacing and physical dimensions of the GBJ case style.

Part Context

This part belongs to the GBJ35005 through GBJ3510 series of 35 Amp glass passivated bridge rectifiers from MCC. The series offers various voltage ratings ranging from 50 V to 1000 V while maintaining consistent current handling and package geometry. This standardization allows for design flexibility across different voltage requirements without changing the mechanical footprint.

Replacement Considerations

Direct substitutes include the SMC Diode Solutions GBJ3508, which shares identical electrical ratings and package dimensions. Other compatible alternatives may include parts from Vishay or Rectron within the same GBJ form factor, provided their electrical specifications meet or exceed the 35 A and 800 V requirements.
