GBPC3510W

Overview

The onsemi GBPC3510W is a single-phase bridge rectifier from the GBPC35W series, designed for high-power applications. It features a peak repetitive reverse voltage (Vrrm) of 1000 V and an average forward rectified current (If) of 35 A. The device supports a peak non-repetitive forward surge current (Ifsm) of 400 A. Key electrical parameters include a maximum forward voltage (Vf) of 1.1 V at rated current and a maximum reverse leakage current (Ir) of 500 µA. It operates within a junction temperature range of -55°C to +150°C and utilizes a GBPC through-hole package with dimensions of 29 mm x 29 mm x 11.23 mm.

Feature Summary

• Integrated heat sink construction provides low thermal resistance for efficient heat dissipation.
• Isolated case-to-lead insulation voltage exceeds 2500 V for enhanced safety.
• Silver-plated terminals facilitate reliable soldering in accordance with MIL-STD-202 Method 208.
• Lead-free construction compliant with environmental standards.

Applications

• Industrial power supply units requiring robust rectification.
• AC-DC conversion circuits in heavy-duty equipment.
• Battery charging systems with high surge current demands.

Procurement Notes

Verify the specific suffix 'W' against official datasheets to confirm terminal plating specifications, as this variant typically denotes silver-plated leads compared to standard nickel-plated versions. Ensure compatibility with mounting torque limits of 20 in-lbs during assembly. Confirm UL recognition number E258596 if regulatory compliance is required for the final product design.

Selection Notes

Select the GBPC3510W when a 1000 V rating is necessary for mains or industrial AC inputs. The 35 A continuous current capability suits moderate to high-power loads. Consider the GBPC-W package specifically for applications requiring superior solderability or specific thermal management profiles associated with silver terminations versus standard nickel finishes.

Part Context

This component belongs to the GBPC35W series, which offers various voltage ratings within the same mechanical footprint. The '10' in the model number indicates the 1000 V reverse voltage class. It shares physical dimensions with other GBPC35xx variants but differs electrically in breakdown voltage and potentially terminal treatment based on the W suffix.

Replacement Considerations

Direct substitutes include the GBPC3510 for standard nickel-plated terminals. Other manufacturers offering equivalent 35 A / 1000 V GBPC packages may serve as alternatives, provided thermal and electrical ratings match exactly.
