GBPC3510

Overview

The onsemi GBPC3510 is a single-phase silicon bridge rectifier rated for a peak repetitive reverse voltage of 1000 V and an average forward current of 35 A. It utilizes the GBPC through-hole package with four pins, measuring 29 mm in length and width, and 11.23 mm in height. The device supports a peak non-repetitive forward surge current of 400 A and operates within a junction temperature range of -55°C to +150°C. Key electrical parameters include a maximum peak forward voltage of 1.1 V at 17.5 A and a maximum peak reverse current of 5 µA at 1000 V.

Feature Summary

• Features an integrated heat sink design that provides low thermal resistance for effective heat dissipation.
• Offers high isolation capability with case-to-lead insulation voltage exceeding 2500 V.
• Includes UL certification (E258596) for safety compliance.
• Utilizes silver-plated terminals for wire-type GBPC-W packages to facilitate welding per MIL-STD-202 Method 208.

Applications

• Industrial power supply units requiring robust AC-to-DC conversion.
• Welding equipment power stages.
• General-purpose rectification in high-voltage DC circuits.

Procurement Notes

Verify the specific ordering suffix against official datasheets to confirm terminal plating and packaging variations. Confirm RoHS compliance status and lead-free designation as required by project specifications. Ensure the supplier provides valid traceability documentation matching the manufacturer's part number to avoid counterfeit components.

Selection Notes

Select this component when a single-phase rectifier with 1000 V blocking capability and 35 A continuous current is required. The GBPC package is suitable for chassis or board mounting where screw termination is preferred over surface mount technology. Consider the 1.5°C/W junction-to-case thermal resistance for heatsink calculations in high-power applications.

Part Context

The GBPC3510 belongs to the GBPC35W series of bridge rectifiers from onsemi. This series is designed for general-purpose applications requiring high reliability and efficient thermal management. The part is manufactured using standard silicon junction technology and is distinct from lower-current variants within the broader GBPC family.

Replacement Considerations

Cross-reference with other manufacturers offering equivalent GBPC-4 packages rated for 1000 V and 35 A. Verify pinout compatibility and thermal resistance characteristics before substitution. Ensure mechanical dimensions match the existing footprint constraints.
