GBPC3502W

Overview

The onsemi GBPC3502W is a single-phase bridge rectifier from the GBPC35W series, rated for a maximum repetitive reverse voltage of 200 V. It supports an average rectified forward current of 35 A at a case temperature of 55°C and withstands a non-repetitive peak forward surge current of 400 A. The device features a low thermal resistance junction-to-case of 1.5°C/W and operates within a temperature range of -55°C to +150°C. Packaged in a GBPC-W configuration with wire leads, it utilizes silver-plated terminals suitable for soldering per MIL-STD-208.

Feature Summary

• Integrally molded heat sink provides very low thermal resistance for maximum heat dissipation
• Surge overload ratings support up to 400 A for the GBPC35 series
• Case to lead isolation voltage exceeds 2500 V
• Terminals feature silver finish material for improved solderability

Applications

• General-purpose AC to DC power supply conversion
• Industrial motor drive rectification circuits
• Battery charging systems requiring high surge tolerance

Procurement Notes

Verify the specific suffix 'W' indicates the wire lead structure variant rather than the standard pin-through-hole package. Confirm that the component meets RoHS compliance standards as indicated by the manufacturer's Pb-Free designation. Ensure the ordering information matches the required voltage rating of 200 VRRM for the intended circuit design.

Selection Notes

Select this component when a 200 V reverse voltage rating is required alongside a 35 A continuous current capacity. The GBPC-W package is appropriate for applications necessitating wire termination instead of through-hole pins. Consider the 400 A surge capability for circuits experiencing significant inrush currents during startup or fault conditions.

Part Context

This part belongs to the GBPC 12, 15, 25, 35 Series of glass-passivated bridge rectifiers manufactured by onsemi. The series offers various voltage ratings from 50 V to 1000 V, sharing common mechanical dimensions and thermal characteristics. The GBPC3502W specifically denotes the 35 A current class with a 200 V blocking voltage.

Replacement Considerations

Compatible alternatives include the GBPC3502 (pin version) for identical electrical performance with different termination. Other manufacturers offering equivalent GBPC form factor rectifiers may be considered if they meet the 200 VRRM and 35AIF(AV) specifications.
